A bug zapper barely made a dent. Citronella candles just smelled like a campfire. A single bat can eat up to 600 to 1,000 mosquitoes in an hour, according to the product descriptions for these bat boxes. The real trick is getting bats to stay in your yard, and that is what a well-built bat box does.

How To Choose The Best Bat Box
Picking the right bat box depends on four big decisions: the number of chambers, the material and construction, the size of the entrance slot, and where you are going to mount it. Mess up any one of these, and your bat box ends up as an expensive birdhouse that nobody moves into.
Chamber Count: Why More Is Often Better
A single-chamber bat box might hold a few solitary bats, but a multi-chamber design (2, 3, or 4 chambers) creates different microclimates inside the box — the bats can move between chambers to find the perfect temperature. The data shows that larger, multi-chamber bat houses have higher occupancy rates. For a serious mosquito-control effort, look for at least 2 chambers; for a nursery colony, go for 3 or 4 chambers.
Wood and Construction: Cedar is the Gold Standard
All the models in this list use cedar wood, and for good reason. Cedar is naturally rot-resistant and holds up against rain, sun, and temperature swings far better than pine or plywood. The best builds also use decking screws instead of ordinary nails and include a rough interior surface (grooved wood or nylon mesh) so bats can grip the walls easily to climb and roost.
Entrance Slot and Venting
Bats need a narrow entrance — typically around 3/4 of an inch — to keep out predators like wasps and larger birds. A bat box also needs air vents on the sides or front to prevent overheating. Without proper ventilation, the interior can become dangerously hot for a bat colony on a summer afternoon.
Mounting Height and Sunlight
The experts across these product manuals agree: mount your bat box 12 to 20 feet high on a pole, tree, or building, facing south or southeast. It needs at least 6 hours of direct sunlight each day. The dark color of the box helps absorb heat, which is critical because bats need a warm environment — around 80 to 100 degrees Fahrenheit — to raise their young.

In‑Depth Reviews
1. WHITEHORSE 4-Compartment Bat House (Black)
Four chambers and a 3/4-inch gap that wasps cannot squeeze through.
The WHITEHORSE 4-Compartment gives you a compact house built from 100% FSC (Forest Stewardship Council, a certification for sustainable wood) western cedar, coated with 3 layers of exterior-grade water-based paint. This is a real durability upgrade over entry-level models. At 16.93 inches tall by 9.84 inches wide by 5.51 inches deep, it is compact enough to mount on a building side but still offers four separate roosting chambers (spaces inside the box where bats cluster together) for a growing colony. The 3/4-inch chamber opening is a deliberate design choice that reduces the risk of wasp nesting. Buyers report this is a major advantage over cheaper houses that fill with insects.
Installation is straightforward: the box comes with exterior-grade mounting hardware and access to a MTBC-approved (Merlin Tuttle’s Bat Conservation, a bat science group) guide with 5 proven methods to attract bats. Unlike some other models that arrive pre-assembled but with rough edges, owners mention that WHITEHORSE uses thick cedar with no gaps or splinters and that the three smooth paint coats make it ready to mount immediately. It is the first American company to be endorsed by Merlin Tuttle’s Bat Conservation for this specific design. That endorsement adds real credibility if you want confidence that bats will actually use it.
Why It Stands Out
- 4 chambers give bats more temperature options compared to the 2-chamber INCLY or Sobalai models.
- 3/4-inch entrance slot blocks wasps, a common complaint with other bat boxes.
- Three coats of exterior paint mean it lasts longer than the unsealed cedar options like the Outer Trails.
The Trade-Off
- Requires assembly (some customers note a minor door-clasp misalignment that took a drill to fix).
- It is a mid-range price, not an entry-level impulse buy.
the balance pick: If you want a bat box that is built to last, has a proven design, and blocks wasps, this is the one to get. You could pick the Nature’s Way CWH6 if you need more sheer capacity, but the WHITEHORSE wins on convenience and insect-proofing.
Hold off if: You need a house for a very large colony — the Nature’s Way CWH6 holds more bats (up to 300) at a bigger size.
2. Nature’s Way Bird Products CWH6 Triple Chamber Cedar Bat House
A triple-chamber nursery that holds up to 300 bats for serious mosquito control.
This is the large-format king of the list. At 20.5 inches tall by 12 inches wide by 5 inches deep, the Nature’s Way CWH6 is significantly bigger than the WHITEHORSE 4-Compartment, and it uses three chambers to provide roosting space for up to 300 bats. If mosquitoes are a real problem in your yard, this is the house that can bring in a colony large enough to make a visible difference.
What sets the CWH6 apart is the interior design: it has a nylon hanging mesh that gives bats a surface to grip without the risk of rust or scratching that metal mesh causes. The base of the house has landing kerfs (small grooves) so bats can land and climb in easily. The construction uses stainless steel screws instead of nails, which buyers confirm feels solid and durable. One reviewer called it “the luxury condo of bat houses.” The main caveat is that no mounting hardware is included — you need to figure out your own pole or mounting solution, and some buyers used hook-and-eye screws with bungee cords.
The Big Draw
- 300-bat capacity is class-leading on this list — far more than the 75-bat Sobalai or North States models.
- Nylon mesh is safer for bats than metal mesh and will not rust.
- Stainless steel screws and good wood quality mean it will last for years.
The Catch
- No mounting hardware or instructions included — you have to buy your own.
- One reviewer noted the actual usable capacity is closer to 30 large brown bats, not 300.
Best for large properties: If you have the space to mount a big house 20 feet high and want maximum bat occupancy, choose this one. It outpaces the compact WHITEHORSE 4-Compartment by sheer numbers.
skip it if: You want a simple, all-in-one kit with hardware included — go with the WHITEHORSE Certified instead.
3. WHITEHORSE Certified 3-Chamber Nursery Bat Box (Cedar)
A premium, MTBC-certified nursery built from 3/4-inch thick cedar that holds up to 225 bats.
If you want the gold standard in bat conservation, this is it. The WHITEHORSE Certified 3-Chamber is the largest and heaviest model here — 27.5 inches tall by 16.5 inches wide by 7 inches deep, weighing 13 pounds. It is built from fully certified 100% FSC cedar that is 3/4 of an inch thick, which is more substantial than the thinner cedar used on budget models like the INCLY or North States houses. The chambers are also 3/4 of an inch wide to reduce the chance of wasps moving in.
The big differentiator is the certification: it has been inspected and certified by Merlin Tuttle’s Bat Conservation, one of America’s most renowned bat scientists. This is not a marketing claim — it means the dimensions, venting, slot size, and interior surface have been verified by a bat specialist. The box comes with exterior-grade mounting hardware and a guide on 5 proven methods to attract bats, so you are not left guessing. Buyers praise the thick cedar and the easy 15-minute installation, noting it feels built to last for many seasons without needing a sealer.
Why Go Premium
- MTBC and CWF (Canadian Wildlife Federation) certified — the only model here with verified bat-science approval.
- 3/4-inch thick cedar is noticeably sturdier than the thinner wood on the North States or Outer Trails houses.
- Includes mounting hardware and a detailed attract guide.
What to Know
- It is the most expensive box on this list.
- At 13 pounds, it needs a very sturdy pole or wall mount.
For the bat enthusiast: If you are serious about bat conservation and want a scientifically verified home, this is the one. It is the only pick that comes with a bat specialist’s personal stamp of approval.
Not for casual buyers: If you only want a simple, cheap box to hang in a tree, the INCLY or Sobalai will work fine for a fraction of the cost.
4. Outer Trails Cedar Bat Houses for Outdoors, Natural Wood, 3 Chamber
A three-chamber cedar house at a mid-range price that is ready to hang from the start.
At 15 inches high by 9.25 inches wide by 4.75 inches deep, the Outer Trails 3-Chamber is a good middle-ground size — noticeably bigger than the 2-chamber budget models like the INCLY but more compact than the massive Nature’s Way CWH6. The natural cedar is already varnished to resist moisture and UV rays (ultraviolet light from the sun), so you do not have to paint it yourself. Buyers consistently praise the build quality and the price, with one experienced buyer saying it was the best-priced house they had found in years.
One thing to note: the varnish is not a heavy-duty seal, and several buyers recommend adding your own water sealer for extra weather protection. One reviewer noticed the front lower panel was not nailed properly on one side and separated after mounting, so it is worth giving the whole box a quick check-over before you hang it. The back hook makes mounting to trees or poles fast, and the three grooved chambers give a small colony plenty of space. Compared to the North States 3-chamber at a similar price, the Outer Trails is slightly taller (15 inches vs 12 inches) and offers a more modern look.
What Works
- Three chambers for the same price as many 2-chamber models like the INCLY.
- Pre-varnished cedar resists weather from the start.
- Back hook makes mounting to a tree trunk fast.
Watch For
- Some buyers felt the wood was thinner and more fragile than expected.
- Adding your own water sealer is recommended for best longevity.
Smart budget-conscious choice: If you want a 3-chamber box without paying premium prices, this is the one to grab. It gives you more chambers than the INCLY for about the same money.
pass on it if: You need a heavy-duty, thick-cedar house — the WHITEHORSE models are more substantial.
5. North States 3 Chamber Outdoor Bat House
A vented cedar house at a budget price that holds 75 brown bats.
The North States 3-Chamber is a compact, well-designed box that measures 12 inches tall by 9 inches wide by 5.25 inches deep. It is built from heavy-duty, rot-resistant cedar wood and has a specific feature that many budget houses skip: air vents on the sides and front of the house for proper ventilation. This is important because overheated bat boxes are often abandoned by bats, and the North States box addresses that directly. It also has landing kerfs at the base and grooved interior walls to help bats climb and roost.
Because of its smaller size, the North States box is unobtrusive in a backyard and easy to hang with the pre-drilled back holes. One buyer mentioned that its small size and natural wood finish blended in perfectly behind leaves. The main quibble from buyers is that the front label is attached with heavy staples that can dent the soft wood when you pry them off. Overall, it is a solid, functional 3-chamber house at an entry-level price.
what separates it
- 3 chambers for the price of 2-chamber competitors like the Sobalai.
- Side and front air vents prevent dangerous overheating — a feature the INCLY lacks.
- Compact size is easy to mount on a small tree or fence post.
One Quirk
- The front label is stapled on — removing it can damage the wood.
- Smaller capacity (75 bats) compared to larger multi-chamber designs like the Nature’s Way CWH6.
Best for small yards: If you have a modest lot and want a well-vented 3-chamber house that fits a tree, this is a fine choice. Its vents make it safer than the INCLY on hot days.
Look elsewhere if: You need to host a large colony — the Nature’s Way CWH6 holds 4 times as many bats.
6. INCLY Bat House for Outdoors 15″ x 9.2″ x 3.2″ Double Chamber
An affordable, pre-assembled cedar house with decking screws for a strong build.
The INCLY 2-Chamber is the entry-level pick that gets the fundamentals right. It is made from premium cedar wood and uses decking screws instead of regular nails, which means the joints will not loosen over time like cheaper nailed-together boxes. At 15 inches high by 9.2 inches wide by 3.2 inches deep, it has narrow interior dimensions that help retain heat — exactly what bats need to stay warm. The interior surface and landing platform are grooved so bats can cling and climb easily.
This bat shelter ships pre-assembled, so you take it from the start and mount it. The mounting hardware is included, and the instructions recommend placing it 10 to 12 feet high in a spot with direct sunlight. One owner reported that they already had bats in the area, and the dark color of the box blended well behind leaves, helping the bats stay around. The main difference between this and the Sobalai 2-chamber is that the INCLY is slightly less deep (3.2 inches vs 3.2 inches — they match on depth, but the INCLY is 15 inches wide vs Sobalai’s 9.4-inch width, so the INCLY is wider).
Why It Works
- Pre-assembled and ready to hang — no DIY work required.
- Decking screws are a step up from nails for long-term durability.
- Grooved interior and landing platform make it easy for bats to enter.
The Limitation
- 2 chambers only — smaller capacity than the 3- or 4-chamber options like the Outer Trails.
- No built-in vents, so monitor sun exposure carefully to prevent overheating.
Good for first-time buyers: If you want to try a bat box without a big investment, this one is well-built and simple to install. It is cheaper than the WHITEHORSE 4-Compartment and a solid test run.
Upgrade if: You are serious about attracting a large colony — a 3- or 4-chamber box has much higher occupancy rates.
7. Sobalai Bat Houses for Outdoors for Tree, 2 Chamber
A sturdy 2-chamber house with a decorative design that attracts bats and compliments your yard.
The Sobalai 2-Chamber Bat House is another strong entry-level option, with a slightly different shape than the INCLY. It measures 15.1 inches deep by 9.4 inches wide by 3.2 inches high (the depth/width/height labeling is unconventional — the actual roosting space is comparable to the INCLY). The box claims to hold up to 75 bats and is made from natural wood with a dark stain. The most noticeable feature is a decorative bat silhouette on the front, which reviewers point out gives it a polished, intentional look rather than a plain box.
Buyers highlight the solid construction and the fact that installation is easy and straightforward with the included screws. One customer observed they applied polyurethane to the exterior because they felt the wood was not fully weatherproof on its own. The Sobalai is best if you are mounting it on a tree in a spot that gets at least 6 hours of direct sunlight.
What You Get
- Holds up to 75 bats in a compact 2-chamber design.
- Decorative bat silhouette on the front looks nicer than plain boxes like the INCLY.
- Solid and sturdy, with easy mounting hardware included.
What to Know
- Some buyers recommend adding a water sealer for full weatherproofing.
- At 2 chambers, capacity is limited compared to 3- or 4-chamber designs like the Outer Trails.
Best if you want curb appeal: If you care about how the bat box looks on your tree and you want a straightforward mount, this is a good pick. The bat silhouette is a nice touch the INCLY does not have.
it’s not for you if: You want multiple chambers for a larger colony — the Outer Trails or North States 3-chamber boxes offer more space at a similar price.
Understanding the Specs
Chamber Count & Capacity
The number of chambers inside the box creates distinct microclimates (small temperature zones) — bats move between chambers to find the right temperature. A 2-chamber house might host a small colony, but multi-chamber designs (3 or 4 chambers) have proven to have much higher occupancy rates because they offer more temperature options. The capacity, measured in “max bats,” is an estimate; real-world occupancy varies by local bat population and box placement.
Interior Surface & Entrance Slot
Bats need a rough surface to grip — look for grooved interior walls or nylon mesh inside the box. The landing platform at the bottom should also be grooved so bats can land easily. The entrance slot should be narrow, typically around 3/4 of an inch wide, which is small enough that wasps and larger predators cannot get inside but bats can slip through easily.

And for a budget-friendly starter box that is pre-assembled and easy to mount, the INCLY 2-Chamber gets the job done while staying affordable.
