The best bat houses earn their spot in a backyard because bats are genuinely useful, not merely interesting. A single bat can eat more than a thousand mosquitoes in an hour, and a modest colony of them works a yard through summer without a drop of pesticide. Bat Conservation International has spent decades studying how to build shelters these animals will actually claim, and the specifications that matter come directly from that research.
I went through the specs, ratings and owner reports on ten of the most-reviewed bat boxes on the market, and the differences are not subtle. Some are cedar with a triple-chamber cavity and a rough grooved interior. Others are thin decorative boxes with a wire hanger. Both are sold as bat houses.
One honest note before the list. Occupancy is never guaranteed, and it is not fast. Most owners wait weeks to a full season before the first bat moves in, and plenty of empty boxes sit on poles for years. A box is one part of a habitat, not a magic switch. If you are wondering whether the money is well spent, read the placement and attraction section further down before you buy, because where the house goes matters at least as much as the house itself.

1. BIGBATBOX Two-Chamber Cedar Bat House – Best Overall
BIGBATBOX Bat House for Outdoors – Large 2 Chamber, Black, Holds 75 Bats
Cedar
2 chambers
Holds 75 bats
15 x 12 x 4 inches
3.88 lb
Pros
- Rot-resistant cedar
- Weather resistant against snow rain and heat
- Attractive finish that blends into a yard
- 75-bat capacity in two chambers
Cons
- High mounting often needs a pole and a second person
- Some boxes arrive with hardware stuck inside
This is the one I recommend to anyone who asks without qualification. It carries a 4.6 rating across more than 4,400 reviews, the largest body of owner feedback on the list, and it sits at the top of the Bat Supplies sales chart. Owners describe the cedar as sturdy and long-lasting, and the black finish genuinely looks good enough that neighbours tend to comment on it.
Two chambers give you a real colony rather than a token handful of bats, and the stated capacity is 75. The box comes apart into six steps with stainless steel hardware included, which is a five-minute job with a screwdriver.
What I like most is the spec sheet honesty. The manufacturer recommends a wall-mounted install, which tells you they expect it high up where a box belongs. The weight at 3.88 pounds is substantial enough to stay put in wind without being impossible to raise on a ladder.
How It Handles Cold Climates and Heat
The cedar holds heat rather well and owners in northern areas report it surviving snow and hard freezes intact. Two chambers also mean bats can choose a warmer or cooler cavity as the season turns, which is exactly why multi-chamber designs show better occupancy.
What to Have Ready Before Mounting
Plan a pole of at least 15 feet with six or more hours of direct sun, and pick a south or southeast facing position. If you are still working out the layout of a large house or property, our guide to covering three-story homes comes later in this article.
2. Kenley Triple-Chamber Cedar Bat Box – Best for Big Colonies
Kenley Bat House – Large Outdoor Bat Box with Triple Chamber – Cedar Wood
Cedar
3 chambers
Pre-assembled
15.3 x 9.5 x 4.9 inches
2.7 lb
Pros
- Pre-assembled so there is no building
- Triple chambers support larger colonies
- Textured platform with perches and skerfs
- Includes a hanger hook and pre-drilled hole
Cons
- Cedar scent can slow early interest
- Occupancy can take two full seasons
The Kenley is the pick if your goal is a healthy colony rather than a decorative yard ornament. It runs a 4.5 across more than 3,400 reviews, and the triple-chamber layout is the design research keeps pointing back to for higher occupancy.
It arrives fully assembled, with a hanger hook and a pre-drilled mounting hole already in place, so the entire install is a matter of choosing a pole or tree and hanging it. At 2.7 pounds it is light enough for one person on a ladder, which is unusual in this category.
The interior platform is textured with perches and skerfs, giving bats a grippy landing surface instead of a smooth face they have to cling to. That detail is small on paper and meaningful in practice, because the landing zone is where a first visit is won or lost.
Owner reports split on how quickly bats find it. Some saw activity nearby within weeks, while others waited a season or more. The fresh cedar scent draws the same comment, and a few buyers say the box smelled strongly enough to slow early interest until it weathered in.
Why Three Chambers Raise Occupancy
Multiple chambers let a colony spread out, separate juveniles from adults, and shift between warm and cool cavities as temperatures change. Research on multi-chamber designs consistently links that layout to higher occupancy in the same yard.
Where It Falls Short
The manufacturer recommends mounting 15 to 20 feet high facing south or southeast, and the box cannot be moved once bats have claimed it. The 4.9 inch depth is generous, but a roost is still a roost, not a winter hibernation shelter for northern species.
3. KIBAGA Double-Chamber Cedar Bat House – Top Rated
The Ultimate Wooden Bat House for Outdoors – Large Double Chamber Box
Cedar
2 chambers
Dark interior
16.5 x 10.2 x 4 inches
3.09 lb
Pros
- 4.7 average rating across 3000+ reviews
- Large body with efficient two-chamber layout
- Dark brown interior matches a natural cavity
- Pre-assembled with screws included
Cons
- Wide footprint needs a sturdy pole or open mounting face
The KIBAGA ties for the highest average rating in the roundup at 4.7, with around 80 percent of its reviews at five stars, and more than 3,000 reviews behind that number. When you want the strongest owner satisfaction signal available, this is the box that carries it.
The design choice that separates it from the pack is the dark brown interior. Bats seek out dark, warm cavities, and a light interior works against the one thing you are trying to encourage. Combined with a 16.5 inch body and a two-chamber layout, the internal volume is unusually generous for this build weight.
Construction is described as waterproof cedar rated for multi-year outdoor use, and it arrives pre-assembled with mounting screws in the box. That means the whole installation is unpacking, choosing a face, and driving three screws.
The trade-off is footprint. At 16.5 x 10.2 x 4 inches it is wide for a wall or a small pole, and a few owners found they needed a sturdier post or a large open mounting face than they first planned. Plan the support before the box arrives.
Why a Dark Interior Matters More Than Color Choice
Exterior color is mostly about heat absorption in cold regions, but the interior decides whether a bat walks in. A dark brown cavity is closer to the unlit tree hollow the species evolved to use, and this box commits to that where many competitors use bare light wood.
Best Fit for Mosquito Control
Owners frame this one as an investment in mosquito control and pollinator support rather than a display piece. If your goal is insect pressure in a yard you actually sit in, the interior volume here gives a small colony room to grow across a season.
4. Applewood Outdoor Two-Chamber Bat House – Premium Pick
Made in USA, Premium-Grade Red Cedar Bat House, 2 Chamber Bat Box, Easy-to-Install Wooden Bat House Kit, Weather-Resistant Bat Houses for Outdoors, Includes Mounting Screws – Applewood Outdoor
Cedar and stain
2 chambers
Grooved interior
3.5 x 11 x 17.25 inches
2.72 lb
Pros
- Built from full 3/4 inch lumber
- Handcrafted in Wisconsin
- Top hook simplifies high mounting
- Brown and black stain options available
Cons
- Some bare wood sections need sealing in wet climates
- Owners report bats can take years to find it
This is an unusually precisely built box. It is made in Wisconsin from US-grown full 3/4 inch lumber, which is thicker than the board many competitors use, and that difference is obvious the moment you unbox it.
It holds a 4.7 rating with about 81 percent five-star reviews across more than 1,800 reviews. Owners consistently describe the craftsmanship, and several single out the manufacturer for responsive customer service, which is rarer in this category than it should be.
The top hook deserves a mention. Mounting a bat house at 20 feet is unpleasant work, and this design lets you hang the box after the pole is already in place instead of carrying the full weight up with you. Pre-drilled mounting holes and three 2.5 inch screws are included.
The interior is narrow by design, which helps it hold heat through cold snaps. A black grain-penetrating stain handles weather, and the box is also offered in cedar, brown and an XL three-chamber version if you outgrow the two-chamber model.
How the Narrow Cavity Holds Heat
Smaller internal volume is an advantage in cold regions because bats raise their own body heat to stay warm, and a tight chamber loses less of it. The grooved narrow interior is built around that logic rather than around maximizing bat count.
Preparing It for Rainy Regions
Some sections arrive as exposed unfinished wood, and owners in wet climates recommend sealing those before mounting. Several buyers also caution that bats can take years to find a box, so treat the first season as a waiting period rather than a failed test.
5. VIREESR Castle Three-Chamber Bat Box – Best for Decorative Yards
VIREESR Bat House for Outdoors, Castle 3-Chamber Bat Box, 100-Capacity
Cedar
3 chambers
Holds 100 bats
16 x 9.2 x 4.4 inches
2.6 lb
Pros
- Distinctive castle styling owners call attractive
- High stated capacity of up to 100 bats
- Brown and black finishes absorb heat
- Arrives assembled with a rear bracket
Cons
- Thin wire hanger cannot carry the box
- Vent holes may need sealing for winter
- Landing pad at the entrance is small
This is the one to buy when the box has to look good on a fence or a garden wall. Reviewers describe the castle styling as cute and attractive often enough that it comes up in the majority of positive comments, and the three-room layout carries a stated capacity of up to 100 bats.
It arrives assembled and mounts with a single rear triangle bracket. Brown, black and distressed wood finishes are offered in medium and large sizes.
I want to be straight about the weak point, because it is the reason this box sits fifth rather than higher. The thin wire hanger loop is not strong enough to carry the box, and a number of owners ended up building their own pole or wall bracket. No mounting screws are included either.
There is also a cluster of detailed negative reviews about the small landing pad at the entrance, vent holes that may need sealing before winter, and a few units that arrived needing reassembly with a bowed interior wall. It is the lowest-rated pick here at 4.3, with around 9 percent one-star reviews.
Whether the Hanger Can Hold It
Do not trust the wire loop with this one. Owners consistently report modifying the mount with a pole or bracket, and that modification takes ten minutes. Build the support first, then hang the box on it.
Where It Falls Behind the Cedar Leaders
The landing pad at the entrance is small relative to what bat design guides recommend, and the thin construction did not hold up for everyone through a full winter. If durability matters more than looks, the cedar builds above are the safer bet.
6. INCLY Double-Chamber Cedar Bat House – Best for Mosquito Control
INCLY Bat House for Outdoors 15″x9.2″x3.2″ Shelter Box kit Double Chamber Dark Natural Cedar Wood, Pre-Finished Easy to Install
Cedar
2 chambers
15 x 9.2 x 3.2 inches
Screw-built
Pros
- Owners report bats moving in and fewer mosquitoes
- Decking screws give a sturdier box than nails
- Holds up through direct summer sun and winter cold
- Dark color blends into foliage
Cons
- Factory finish wears faster than expected
- Stain fades in strong sun and needs refinishing
Of the ten boxes here, this is the one with the most owner reports of bats actually moving in and mosquitoes dropping as a result. That is the outcome you are buying, so it carries more weight than any other spec on the list.
It measures 15 x 9.2 x 3.2 inches and uses decking screws instead of nails, which gives a noticeably sturdier box. The grooved interior and landing platform give bats something to cling to and climb on rather than a flat wall.
Owners report it holding up through two summers of direct sun and winter cold, and the narrow interior retains heat in cold weather. It arrives pre-assembled with mounting hardware included, and a no-questions-asked replacement policy covers the first-year risk.
The consistent complaint is finish durability. The brown coating wears and fades faster in strong sun, particularly in dry desert climates, and some owners add their own water sealer after the first season. Plan on a refinish roughly every year or two if you live somewhere bright.
Why Screws Beat Nails Here
Decking screws resist the racking and twisting that splits a nailed box when wind loads it from the side. On a structure that spends its whole life outdoors on a pole, that difference shows up as a longer useful life.
Setting the Mounting Height
The manufacturer guidance is 10 to 12 feet in a sheltered, sunny spot, which is lower than the 15 feet many wildlife guides suggest. If bats are already living nearby, the lower mount is fine, but a taller pole is the safer choice for new locations.
7. MIXXIDEA Double-Chamber Cedar Bat House – Best for Small Colonies
MIXXIDEA Bat House Bat Box Double Chamber Outdoor House Nursery Bat Shelter Habitat Big bat Box Handcrafted from Cedar Wood – Easy for Bats to Land and Roost – Weather Resistant & Ready to Install
Cedar
2 chambers
Narrow cavity
7.9 x 13.4 x 5.5 inches
3.11 lb
Pros
- Handcrafted cedar with decorative grooved panels
- Grooves between chambers give climbing support
- A compact 7.9 inch width suits small colonies
- Weather resistant for year-round exposure
Cons
- Listed dimensions vary between the listing and spec sheet
- You supply your own screws and mounting surface
The MIXXIDEA is a compact box that works well when you want a couple of bats in the yard rather than a full colony. Around 75 percent of its reviews are five stars across more than 670 reviews, which is a solid satisfaction rate.
The narrow internal size is deliberate. Small cavities insulate better in winter, and this one pairs that with grooved interior surfaces and grooves between the chambers that bats use to climb. The decorative grooved side panels also make it look good on a tree or a wall.
At 7.9 inches wide it is a compact box, which makes it easy to hang on a modest post or a mature tree without needing a heavy pole. The install is a two-step process: drive screws into the mounting points, then hang the box.
Two things to check. The listing and the spec sheet give slightly different dimensions, so measure the box when it arrives. You also supply your own screws and a drilled surface, so buy hardware before the box is in the air.
Whether a Small Box Is Enough
Interior volume is the limiting factor here. This box supports a handful of bats comfortably, so it suits a yard where you want insect control and occasional viewing rather than a growing colony you will need to expand next season.
Finishes and Climate Fit
Black, brown and natural wood options are available, and the choice matters more in cold regions where the exterior absorbs heat to keep the cavity warm. In the desert or deep south, light finishes reflect more sun and keep the interior from becoming an oven.
8. North States Three-Chamber Bat House – Best for Easy Install
North States – Outdoor Bat House for Mosquito Control with 3 Roosting Chambers, Holds 75 Brown Bats – Natural Wood
Cedar
3 chambers
Holds 75 bats
5.25 x 9 x 12 inches
2.1 lb
Pros
- Weighs just 2.1 pounds for easy handling
- Three chambers with front and side vents
- Pre-drilled back holes accept screws
- Natural wood finish suits landscaping
Cons
- Landing skerfs and vents are more basic than premium models
- High mounting is still awkward solo
This bat house weighs 2.1 pounds, and that weight is the whole selling point. It is the box you can raise onto a pole by yourself, which is the step that stops a lot of installs from happening at all.
It holds three roosting chambers with a stated capacity of 75 brown bats, and unlike some basic triple-chamber designs it includes proper air vents on the front and sides. Ventilation matters more than most listings admit, because a sealed cavity in summer heat becomes unusable.
Pre-drilled mounting holes on the back panel take screws directly into a tree, fence, post or house wall, and the package includes a bat facts card. The natural wood finish looks unremarkable in a good way, blending into landscaping rather than standing out.
The trade-off is refinement. The landing skerfs at the base and the vent layout are more basic than what the premium triple-chamber models offer, and even at 2.1 pounds, getting it 15 feet up on a ladder alone is still awkward. A second pair of hands makes it painless.
When Weight Is the Deciding Factor
If you have no pole, no ladder, or no helper, install difficulty is the real spec. This box is light enough to hold overhead while you drive the first screw, and that removes the most common reason a bat house never goes up.
How the Vents Help in Summer
Front and side vents keep air moving through the chambers so the cavity does not trap afternoon heat. Roosting bats need a stable warm zone they can leave when it gets too hot, and ventilation is what makes that possible without a second box.
9. Nature’s Way CWH6 Triple-Chamber Bat House – Best for Maximum Capacity
Nature’s Way Bird Products CWH6 Triple Chamber Cedar Bat House, 20.5″ x 12″ x 5″
Cedar
3 chambers
Holds 300 bats
20.5 x 12 x 5 inch chamber
5.9 lb
Pros
- Up to 300 bats
- the most capacity in our roundup
- Nylon hanging mesh will not rust or cut bats
- Stainless steel screws throughout
- Extended base with landing kerfs
Cons
- Bulky at 20.5 inches and needs a substantial support
- Heavy build so mounting needs a helper
The stated rating is up to 300 bats, well beyond anything else in the roundup, and the design is the one wildlife organisations point to when they discuss multi-chamber occupancy research.
Hardware detail separates it from cheaper builds. Nylon hanging mesh will not rust, corrode, scratch or cut bats the way metal mesh can, and stainless steel screws run throughout the structure. The extended base carries landing kerfs that make entry and climbing easier.
At 5.9 pounds it is a much heavier build than most in this roundup, and that weight works in your favor in wind, since a large box on a pole in an open yard is exactly the kind of thing that gets spun around in a storm.
The practical problem is size. A 20.5 inch wide chamber needs a substantial pole or a broad wall face, and getting it high requires two people and a ladder. If you have ever wanted a colony big enough to notice from across the yard, this is the box and the headache together.
Why the Hardware Choice Matters
Metal mesh and plated screws corrode over a decade outdoors, and rust has sharp edges that can injure bats entering the cavity. Nylon mesh and stainless steel remove that failure mode entirely, and that hardware choice is a large part of why this build sits at the top of the range.
Whether You Actually Need 300 Bats
Most yards support a small to mid-size colony, so this box is generous rather than necessary. It makes sense for a large property, a woodland edge, or a conservation project, and it is overkill for a typical suburban backyard.
10. Sobalai Two-Chamber Bat House – Best Value
Sobalai Bat Houses for Outdoors for Tree, 2 Chamber Bat Boxes for Outside to Attract Bats to Land and Roost, Durable and Easy to Hang
Natural wood
2 chambers
Holds 75 bats
15 x 11 x 4 inches
Pros
- 4.6 average rating from 375 reviews
- Decorative bat silhouette on the front
- Three mounting screws included
- Stained finish blends into landscaping
Cons
- Material is thin
- Smaller than buyers expect
- Tree mounting is not really supported
The Sobalai rates 4.6 across 375 reviews, a strong result for a budget box. The front panel carries a simple bat silhouette that looks clean on a shed wall or a tree without turning the yard into a novelty.
Inside there is a small alcove and landing kerfs to make roosting easier, and the box handles two chambers with a stated capacity of 75 bats. Three mounting screws come in the package, and the manufacturer recommends a southeast wall or a 15 to 20 foot pole with six or more hours of sun.
The listing describes corrosion-resistant natural wood rated for ten or more years outdoors, and a one-year warranty covers the first season. One owner documented occupancy after roughly a year, which fits the normal timeline for this category.
The two negative reviews both concern thin material, including a report of the roof detaching after two years unopened, and several buyers warn that the box is smaller in person than the listing dimensions suggest. Despite the product title, it is not really designed for tree mounting, so use a pole or wall instead.
What to Reinforce Before the First Winter
If the walls feel thin in your hands, a coat of exterior sealant on the seams and roof is a cheap precaution against weather. The reported roof failure came after two unopened years, so an annual visual check is enough to catch anything early.
Best Value for a Starter Box
This is the sensible first bat house for someone who wants to test whether bats use their yard at all. The rating backs the value, the mounting advice is specific, and the screws are included, which is more than several picks in this roundup offer.
How to Choose a Bat House Bats Will Actually Use
Six specifications decide whether a bat house works, and everything else is decoration. Check these in order and you will not spend money on a pretty box that stays empty.
Interior depth. The cavity needs enough depth to stay dark and hold heat. Shallow single chambers around three quarters of an inch deep are ornamental. The boxes in this roundup run from roughly 3.2 to 5.5 inches deep, which is where actual roosting happens.
Chamber count. Research on bat house design links multi-chamber layouts to higher occupancy, because a colony can spread out and choose between warm and cool cavities. Two chambers is a sensible starting point, three gives more room.
Surface roughness. Bats need a textured surface to grip with their feet and climb on. Look for grooves, skerfs or kerfs on the landing platform, between chambers and along the interior walls. Smooth plywood interiors are a bad sign.
Roof overhang and drainage. The roof needs to throw water clear of the entrance. Water running down the front face soaks the landing zone and deters bats, and it drives rot into the base where the box meets the support.
Material and hardware. Cedar resists rot naturally and carries its own oils. When the box is wood, the fasteners decide how long it lasts. Screws outperform nails, and stainless steel or nylon hardware will not corrode into sharp edges over a decade outdoors.
Rear access and mounting hardware. A rear panel or back board lets you check and clean the interior without dismantling the front. This matters more than most listings suggest, because you will want to inspect the box at least once a year.
Color is a secondary consideration, but it is not trivial. Dark brown or black finishes absorb heat and suit northern and cold regions, natural and mid-tone wood suits temperate zones, and light finishes reflect sun in the desert and deep south. If you are also sorting out hardware for a larger property, our guide to covering three-story homes covers that side of things.
One clarification on roosting versus hibernation, because cold-climate buyers ask this constantly. A bat house like every one on this list is a roost for the active season. It is not a hibernation shelter. Bats that hibernate need a specific cave or mine with stable humidity and temperature, which no backyard box provides.
When to Install a Bat House and How to Attract Bats
Put the house up before the season begins, and mount it at 15 feet or higher in a spot that gets at least six hours of direct sun. TractorByNet forum consensus is 15 feet minimum for a secure, undisturbed roost, and most manufacturers in this roundup recommend 15 to 20 feet facing south or southeast.
Sun is the single biggest factor. A box in permanent shade stays too cold for occupancy no matter how well it is built, and the exterior color choice above exists for the same reason. Shelter the box from prevailing wind without shading it, because wind chill inside a cavity is what drives colonies back out.
Timing matters more than most people expect. Install in late winter or early spring so the box is weathered in and discovered before the season starts. Installing in summer can work, but you will likely wait out the rest of the year for a first occupant.
Then give the bats a reason to be in your yard at all. Permies, the permaculture forum, advises planting as many flowering trees and shrubs as possible and placing bat houses near water rather than relying on the box alone. That is the honest version of how this works: habitat first, box second.
To improve your odds, follow these steps:
1. Darken the interior before mounting it.
2. Choose a south or southeast face with six or more hours of sun.
3. Mount at 15 feet or higher on a pole, away from tree cover.
4. Put a water source within a short flight of the house.
5. Cut or shield bright night lighting near the box.
6. Plant native flowering species that bloom from spring into fall.
7. Wait a full season before judging the result.
On that last point, be realistic. A long-running Houzz discussion shows buyers asking whether bat houses work at all, with a recurring worry that many never get used. That worry is reasonable. Occupancy depends on whether bats already live near you, and the top recommendation in the r/batty thread was a polymer bat house line praised for holding up against harsh weather, which tells you durability is what experienced owners screen for first.
Downsides of Having a Bat House
There are real downsides, and they are manageable. Rabies is the one people fear most, and the honest answer is that the risk to humans is low, but it is not zero. Do not handle a bat bare-handed, and if a bat is active during the day and behaving oddly, leave it and contact animal control.
Guano cleanup is routine but real. Expect droppings beneath the box, and wear gloves when you handle the interior. If anyone in your household is immunocompromised, weigh that before you commit.
Eviction is seasonal. Bats leave in autumn and return in spring, and an occupied house should never be inspected or cleaned during maternity season, roughly May through July. Getting that wrong means evicting a colony that may not come back that year.
Neighbour relations round out the list. A bat house in a shared yard or close to a property line is worth mentioning before you mount it, and some communities regulate outdoor roosts near housing.
Frequently Asked Questions
What is the best bat house to buy?
The best bat house for most people is a cedar box with two or three chambers, a rough or grooved interior, a dark finish and screws rather than nails. Our top pick is the BIGBATBOX two-chamber cedar house for its 4.6 rating across more than 4,400 reviews, its 75-bat capacity and its cedar build that holds up in snow and heat.
Do bat houses really attract bats?
They do, but not instantly and not always. Most owners wait weeks to a full season before the first bat moves in, and occupancy depends heavily on whether bats already live near you. A box in shade or in a yard with no insects, no water and no flowering plants can stay empty for years.
How high should a bat house be mounted?
Mount it at least 15 feet above the ground, with most manufacturers in our roundup recommending 15 to 20 feet. Place it facing south or southeast where it gets six or more hours of direct sun, and shelter it from prevailing wind without blocking the sunlight.
What time of year should you put up a bat house?
Late winter or early spring is best, so the box is weathered in and discovered before the active season starts. Installing later in the year still works, but you are more likely to wait the rest of the season before any bat moves in.
Is there a downside to having a bat house?
The main downsides are guano cleanup, a low but real rabies risk if you handle a bat bare-handed, and seasonal eviction. Never inspect an occupied house during maternity season, roughly May through July, and wear gloves when cleaning the interior.
What is the most effective bat house to build?
Build a two-chamber cedar box with a rough interior, a landing platform with grooves, screws rather than nails, a solid roof with a good overhang, and a rear access panel. Interior depth of at least three inches and multiple chambers are the features research links to higher occupancy.
Final Verdict on the Best Bat Houses
After comparing all ten, the BIGBATBOX two-chamber cedar house is the best bat house for the widest range of buyers. It has the deepest review history on the market, a two-chamber layout that research supports, a capacity of 75 bats and a cedar build that survives real weather.
Pick the Kenley triple-chamber model if you want a larger colony and want it pre-assembled. Choose the KIBAGA if the dark interior matters most to you, and the Applewood build if craftsmanship and thick lumber are your priorities. The Nature’s Way CWH6 suits genuinely large colonies, and the North States box is the one you can raise on a ladder by yourself.
Whatever you choose, mount it high and sunny in late winter, and give the bats a yard worth flying to. Then be patient for a season. Updated for 2026.
