A bat house is one of the few pieces of garden gear that works while you sleep. Insect-eating bats hunt night-flying moths, beetles and other insects, and a well-placed roost gives a small colony a reason to stay near your yard. The catch is that bats are fussy tenants. Chamber width, interior grip, mounting height and sun exposure decide whether a box fills up or hangs empty for years. This guide compares the bat houses currently listed on Amazon, flags what each listing does and does not tell you, and explains how to site a box so it has a real chance of attracting bats for natural pest control in the garden.

The best bat houses for natural pest control
1. WildYard BIGBATBOX Brown Cedar Bat House — Best overall
Two-chamber cedar bat house kit listed for up to 75 bats, with stainless steel hardware for pole, wall or tree mounting.
Check price on AmazonWhy we like it
- Cedar body, which the listing says resists rot and decay.
- Two roosting chambers rather than a single slot.
- Stainless steel mounting hardware comes in the box.
- Listing gives a clear stated capacity of up to 75 bats.
| Specification | Details |
|---|---|
| Material | Cedar |
| Chambers | Two |
| Listed size | About 15 x 12 x 4 inches |
| Stated capacity | Up to 75 bats |
| Hardware | Stainless steel hardware included; six-step assembly |
| Roosting gap width | Not stated in listing |
WildYard BIGBATBOX (brown cedar) — cedar, 2 chambers, ~15 x 12 x 4 in, up to 75 bats, stainless hardware, kit assembly.
The only brand on the shelf that specifies stainless steel hardware
Of the 18 on-topic bat house listings we compared, only the three WildYard listings (brown, black and natural cedar versions of the same Big Bat Box design) say the mounting hardware is stainless steel. That sounds minor, but a bat house is meant to stay up for years in rain and snow, and rusting screws are a common reason a box sags or detaches. Most competing listings simply say hardware or screws are included without naming the metal.
The WildYard is also one of ten listings that name cedar as the wood, and it states a capacity (75 bats), which only nine of the 18 listings do. Note that it ships as a kit: the listing describes six assembly steps, while rivals such as the Outer Trails and INCLY boxes arrive pre-assembled. If you want a box ready to screw to a wall straight out of the carton, that matters. Assembly does give you a chance to run a bead of exterior caulk along the seams, which extension guidance recommends to limit drafts.
What the listing does not state is the width of each roosting crevice, the single most important interior dimension. University of California IPM guidance puts chamber width at 1/2 to 1 inch, and wider gaps invite wasps. Measure the chambers when it arrives. The title advertises tree mounting, but extension sources say bats rarely occupy tree-mounted houses, so plan on a wall or pole.
Pros
- Stainless steel hardware named in the listing
- Cedar construction with two chambers
- Stated capacity helps with planning
- Same design sold in three finishes
Cons
- Requires assembly
- Crevice width not stated
- Smaller than the USDA NRCS minimum size

2. VIREESR Castle 3-Chamber Cedar Bat House — Best multi-chamber roost
Cedar castle-style bat box with three roosting rooms, listed for up to 100 bats, sold assembled with screws.
Check price on AmazonWhy we like it
- Three roosting chambers, the most on this shelf.
- Highest stated capacity we found, up to 100 bats.
- Arrives assembled; screws are included.
- Lists a one-year manufacturer warranty.
| Specification | Details |
|---|---|
| Material | Cedar, brown finish (black version also listed) |
| Chambers | Three |
| Listed size | About 16 x 9.2 x 4.4 inches |
| Stated capacity | Up to 100 bats |
| Weight | About 2.6 pounds |
| Warranty | 1 year |
VIREESR Castle Bat House (brown) — cedar, 3 chambers, ~16 x 9.2 x 4.4 in, up to 100 bats, 2.6 lb, 1-year warranty.
The only three-chamber design among the listings we compared
Every other on-topic listing on the shelf is single- or two-chamber; the VIREESR Castle (sold in brown and black under two ASINs) is the only design that describes three rooms. USDA NRCS guidance says more chambers generally mean better use, because multi-chambered boxes hold temperature more steadily and give a growing colony room to spread out. On paper, that makes this the most bat-friendly interior on the shelf.
The trade-off is that three chambers fit inside a body only about 4.4 inches deep, so each crevice is likely narrow, and the listing never states the gap width. Read the 100-bat figure as marketing rather than a measurement. The NRCS rule of thumb divides cubic inches of roost space by four to estimate capacity, and you cannot run that math without interior dimensions. Two other listings (the Lxnavihly double chamber and both VIREESR colors) also claim 100 bats, so the number alone does not set this box apart.
The castle styling is a matter of taste. A decorative peaked front does no harm as long as the landing area below the entrance stays rough enough to grip. The listing is also one of only a few on the shelf that state a warranty term.
Pros
- Three chambers for temperature choice
- Pre-assembled with screws
- Warranty term stated
- Brown and black versions for different climates
Cons
- Shallow body for three chambers
- Gap width not stated
- Capacity claim cannot be checked from the listing

3. Pickei Large Double Chamber Pine Bat House — Best large unfinished box
Largest box on the shelf at 17.5 x 14.4 x 7.3 inches, unpainted pine, two chambers with a stated 3/4-inch gap.
Check price on AmazonWhy we like it
- Largest listed footprint of any bat house we compared.
- Only listing that states its roosting gap: 3/4 inch.
- No paint, stain or sealant on the wood.
- Pre-drilled, with screws and wall anchors included.
| Specification | Details |
|---|---|
| Material | Solid pine, rough interior, unfinished |
| Chambers | Two |
| Listed size | 17.52 x 14.4 x 7.3 inches |
| Roosting gap | 0.75 inch |
| Weight | About 5.5 pounds |
| Stated capacity | Not stated in listing |
Pickei Double Chamber Bat House — unfinished solid pine, 2 chambers, 17.52 x 14.4 x 7.3 in, 3/4 in gap, 5.5 lb.
The only listing that publishes its roosting gap width
Seventeen of the 18 listings skip the crevice width. Pickei states 0.75 inch, which matches the USDA NRCS technical note: it calls 3/4 inch the best crevice size for most North American bats and warns that gaps over 1 inch attract wasps. When a seller gives you the number that matters most, you can judge the box before it arrives.
It is also the biggest box we found, at roughly 17.5 inches tall and 14.4 inches wide. The NRCS note recommends a box at least 24 inches tall and 14 inches wide. None of the 18 listings reaches that height, but this one comes closest and meets the width. Bigger boxes hold heat more steadily, which matters most where nights stay cool into spring.
Unfinished pine has a downside: it weathers to gray and lacks the natural rot resistance sellers credit to cedar. Caulking the seams and painting or staining the outside (never the inside) can extend its life. Also note that at 5.5 pounds it is the heaviest box we found, so use the included anchors properly on masonry or mount it to a sturdy post.
Pros
- States a 3/4-inch roosting gap
- Largest box on the shelf
- Untreated interior surfaces
- Anchors included for wall mounting
Cons
- Pine rather than cedar
- Heaviest option to mount
- No stated capacity or warranty

4. Outer Trails Japanese Cedar 2-Chamber Bat House — Best compact two-chamber
Pre-assembled Japanese cedar bat house with two deeply grooved chambers and a back hook, about 15 x 9.25 x 3.5 inches.
Check price on AmazonWhy we like it
- Arrives fully assembled with a durable back hook.
- Deep grooves inside both chambers for gripping.
- Listing gives practical siting advice: 12+ feet, open sun.
- Light at about 2.1 pounds.
| Specification | Details |
|---|---|
| Material | Japanese cedar, brown |
| Chambers | Two, grooved |
| Listed size | 15 x 9.25 x 3.5 inches |
| Weight | About 2.14 pounds |
| Mounting guidance | 12 feet or higher in an open, sunny spot |
| Stated capacity | Not stated in listing |
Outer Trails OT108 — Japanese cedar, 2 grooved chambers, 15 x 9.25 x 3.5 in, 2.14 lb, pre-assembled.
One of only three listings that tell you how high to mount it
Only three of the 18 listings give a mounting height: Outer Trails (12+ feet), INCLY (8 to 12 feet) and JAZUIHA (13 to 16 feet). The Outer Trails advice lines up with extension guidance, which puts bat houses at least 10 feet above ground with a clear flight path. A seller that tells you where the box belongs is doing buyers a favor, because poor placement is the usual reason a house sits empty.
The compact body is a good fit for a narrow wall section between windows or a garage side. It is pre-assembled, like the INCLY and JAZUIHA boxes, so there is no kit to build. The listing names grooved interior surfaces on both chambers, a detail only six of the 18 listings mention. Without grooves or rough wood, bats cannot cling to the walls.
What is missing: no stated capacity, no crevice width and no warranty. The 3.5-inch depth for two chambers suggests reasonable gaps, but measure on arrival. As with most boxes here, the listing suggests tree mounting is an option. Skip that and use a wall or pole.
Pros
- Pre-assembled and light
- Grooved interior in both chambers
- Sensible mounting height in the listing
Cons
- Small volume for a growing colony
- No capacity, gap width or warranty stated
- Back hook alone may not suit pole mounting

5. JAZUIHA Large 2-Chamber Black Bat House — Best for cooler climates
Black two-chamber bat house with an unpainted grooved cedar interior, listed for up to 75 bats and a 2-year warranty.
Check price on AmazonWhy we like it
- Dark exterior that absorbs heat in cooler regions.
- Unpainted, grooved cedar inside where bats roost.
- Longest warranty term we found: two years.
- Listing names a 13 to 16 foot mounting height.
| Specification | Details |
|---|---|
| Material | Cedar, black weatherproof exterior, unpainted interior |
| Chambers | Two, with textured landing platform |
| Listed size | About 15 x 10.2 x 4.5 inches |
| Stated capacity | Up to 75 bats |
| Siting guidance | 13 to 16 feet; 4+ hours of daily sun |
| Warranty | 2 years |
JAZUIHA BH001f — black cedar, 2 chambers, ~15 x 10.2 x 4.5 in, up to 75 bats, 4 lb, 2-year warranty.
The only listing with a two-year warranty
Just a handful of the 18 listings state any warranty, and JAZUIHA’s two years is the longest term we found (VIREESR states one year). The black exterior is the other reason to choose it. Bats want a warm roost, and extension guidance notes that dark roofing or shingles help raise interior temperatures, with about 90°F inside considered ideal. In northern states or at higher elevations, a dark box gives you a head start; in hot desert or southern regions a black box can overheat, so pick a natural finish there.
Unlike black-painted boxes that leave you guessing, this listing says the grooved cedar interior is unpainted. Only three listings on the shelf say the wood is left unfinished or unpainted, and it matters because bats roost against those surfaces.
Treat one claim with caution: the listing says each bat eats more than 1,000 mosquitoes nightly. University of California IPM guidance states there is no clear evidence that installing a bat house significantly reduces garden insect problems. Buy it to support bats and enjoy them at dusk, not as a guaranteed mosquito fix.
Pros
- Two-year warranty
- Dark exterior for heat in cool areas
- Unpainted interior and landing platform
- Pre-assembled with hook and hardware
Cons
- Black can overheat in very hot climates
- Overstated mosquito claim
- Gap width not stated

6. INCLY Small Single-Chamber Cedar Bat House — Best for walls and eaves
Slim, pre-assembled single-chamber cedar bat house with a grooved landing platform, 14.6 x 6.7 x 2.2 inches.

- Slim profile suits a house wall or under eaves.
- Grooved interior and landing platform for clinging.
- Natural, unstained finish to soak up sun.
- Lightest box we compared, under one pound.
| Specification | Details |
|---|---|
| Material | Cedar, natural unstained finish |
| Chambers | One |
| Listed size | 14.6 x 6.7 x 2.2 inches |
| Weight | About 0.77 pound |
| Mounting guidance | 8 to 12 feet, sheltered spot with direct sun |
| Stated capacity | Not stated in listing |
INCLY Small Bat House — natural cedar, single chamber, 14.6 x 6.7 x 2.2 in, 0.77 lb, pre-assembled.
A single-chamber box, which belongs on a building
Three listings on the shelf describe single-chamber boxes, INCLY among them. USDA NRCS guidance says single-chamber houses are less thermally stable and should not go on poles; they do best fixed to a building, where the wall adds warmth. That is the right way to think about this box: a small, light roost for a sunny house wall, shed or eave, not a free-standing pole box.
The INCLY listing gets the details right for its size. It describes grooved interior surfaces and a landing platform, and it is one of the few that leave the wood unstained. Its 8 to 12 foot mounting suggestion is on the low side; extension guidance points to at least 10 feet, so aim for the top of that range.
Expect a small bachelor group rather than a nursery colony in a box this size. If bats move in and you want room for more, add a larger multi-chamber box nearby rather than replacing this one. The seller offers a refund or replacement if you are unhappy, though no formal warranty term is stated.
Pros
- Very light and easy to mount on a wall
- Grooved interior and landing area
- Unstained cedar
Cons
- Single chamber, less temperature-stable
- Not suited to pole mounting
- Small colony capacity

How to choose and place a bat house
Size and chambers: read the numbers, not the adjectives
Almost every listing calls itself large. The useful numbers are the outside dimensions, chamber count and crevice width. The USDA NRCS technical note on bat house design recommends a box at least 24 inches tall and 14 inches wide, with roost chambers at least 20 inches tall, and says more chambers usually means better use. None of the listings we compared reaches 24 inches, which is typical of retail boxes, so favor the taller and wider options and consider mounting two boxes back to back on a pole, an arrangement the NRCS note describes as ideal.
For crevice width, aim for 3/4 inch, with 1/2 to 1 inch as the acceptable range. Wider than 1 inch and wasps tend to move in. The NRCS note also gives a quick capacity estimate: divide the cubic inches of roost space by four. Use that rather than marketing figures.
Material and interior surface
Cedar is the most common wood on the shelf, named in ten of the 18 listings, with pine in three. Whatever the wood, the interior must be rough or grooved so bats can hang on, and it should never be treated or painted inside. Caulk exterior seams to limit drafts. University of California IPM guidance also suggests tar paper or dark shingles on the roof and upper sides to raise the interior temperature.
Height, sun and orientation
Mount the box at least 10 feet up, with a clear approach for flying bats and no branches in the way. Bats like morning sun and some afternoon shade in hot regions; in cooler places, more direct sun and a darker exterior help. Keep the box sheltered from prevailing winds. Building walls give the best results according to UC IPM, poles in open areas sometimes work, and bats rarely use houses placed in trees, even though many listings advertise tree mounting. Remember that droppings pile up beneath the box, so do not place it above a door, patio table or window. The droppings are useful: see our guide on how to use bat guano before you sweep it away. Keep the box out of the glare of security floodlights, and plan any exterior lighting so it does not shine on the entrance.
Water, timing and patience
UC IPM notes that bats prefer houses within a quarter mile of water they can drink from on the wing, so a pond, creek or lake nearby helps; our water gardens and ponds section covers adding one. Install before March if you can. It is common for a new box to sit empty for a year or more, so do not move it after one quiet season unless the siting is clearly wrong.
Safety around bats
Bats are beneficial, but they can carry rabies. Never handle a bat with bare hands, teach children not to touch grounded bats, keep pets vaccinated, and avoid breathing dust from accumulated droppings. Place the box away from play areas, since a sick bat sometimes falls from a roost. If bats are already roosting inside your attic or walls, exclusion should be done after young can fly, and a licensed wildlife control operator is the right call for that job.
Building a wildlife-friendly yard
A bat house works best as part of a broader habitat: native plants that draw night-flying insects, a water source and minimal pesticide use. Pair it with a mason bee house and a butterfly house for daytime pollinators, and browse more yard projects in our outdoor living section. If you prefer to build, our guide on building a bird house covers the basic woodworking skills a DIY bat box also needs. For tall pole installs or work high on a two-story wall, a local landscaping pro can set a pole in concrete safely.
Frequently asked questions
How high should a bat house be mounted?
At least 10 feet above the ground, according to University of California IPM guidance, and many installers go higher, around 12 to 20 feet. The approach should be clear of branches so bats can fly straight in. Only three of the listings we compared state a mounting height, ranging from 8 to 16 feet.
Does a bat house really reduce mosquitoes?
Bats eat large numbers of night-flying insects, but UC IPM states there is no clear evidence that putting up a bat house significantly reduces garden insect problems. Treat mosquito claims in listings as marketing. A bat house supports local bats; it is not a substitute for removing standing water.
Can a bat house be mounted on a tree?
It can, but it is the least successful option. Extension and USDA guidance both report that houses on buildings or poles are found and occupied far more often, while tree-mounted houses are shaded, harder to approach and closer to predators.
How long does it take bats to move in?
It varies. Some boxes are occupied in the first season, but it is not unusual for a house to stay empty for a year or more. Installing before March and placing the box near water improves the odds.
What color should a bat house be?
Match the color to your climate. Dark exteriors absorb more heat and suit cooler regions, while natural or light finishes suit hot areas where a black box could overheat. Whatever the outside color, the interior should stay unpainted and rough.
