Handcrafted from cedar and finished in black, the Bat Barn Junior holds up to 50 bats across two chambers. Same barn profile as the full-size Big Bat Barn, scaled for a standard garden.
Two chambers, up to 50 bats. Two crevices give a starting colony depth and a choice of temperature through the day — the main advantage over a single-chamber habitat.
Why the black finish. Black stores daytime heat and releases it after dark, which suits cooler regions and higher ground. Where summers run hot, the brown finish is the better match.
Rough-sawn interior. Both chambers are grooved so bats can climb and hang securely — the detail that decides whether a habitat gets used.
Garden-scaled barn. The barn shape without the footprint. Mounts on a pole or high on a wall where the full-size barn would dominate.
Handcrafted cedar, built to last. Arrives fully assembled with mounting hardware and the Bat Conservation International siting guide. No expertise required.

One-chamber bat houses are a popular choice for smaller gardens and yards. If you have limited space, a one-chamber bat house is a great choice because it won't take up too much room. However, if you have a larger property, you may want to consider a 2-chamber or 3-chamber bat house, which can provide more space for bats to roost.
One of the main advantages of a two-chamber bat house is that it can accommodate more bats than a one-chamber bat house, making it a great option for larger properties or those looking to attract more bats. The additional space also provides a more comfortable environment for bats to roost and raise their young.
Three-chamber bat houses offer several key advantages over one- and two-chamber designs. They provide more space for larger colonies, support better temperature regulation throughout the year, and encourage social bonding among bats, which can enhance pest control. Built from durable, high-quality materials, these bat houses are a long-lasting and practical choice for any bat enthusiast.

Size affects both capacity and climate control. A 2-chamber bat house can host around 50–75 bats and suits smaller yards or bachelor colonies. Larger 3- or 4-chamber bat houses can hold several hundred bats, including maternity groups, and they retain heat more evenly—important in regions with wide temperature swings.
Too small can limit success, but too big is rarely a problem. If you have space and sun exposure, choosing a larger house gives you the best long-term results.
The best bat house color depends on your local climate. Darker colors, like black or dark brown, absorb more heat and work well in cooler regions with mild summers. Medium shades, such as natural wood or mid-tone brown, suit temperate areas. Light colors, like cedar or tan, reflect sunlight and are best in hot climates where summers regularly exceed 95°F (35°C). The goal is to keep the bat house interior within the preferred range of 80–104°F (27–40°C).
For example in the US:
If you’re unsure, it’s usually better to go a bit darker, especially in areas with cooler nights.
The capacity depends on size and placement. A 2-chamber bat house may host 50–75 bats, while larger 3- or 4-chamber houses can support several hundred, including maternity colonies.
Since bats cluster for warmth, providing enough roosting space helps them thrive. If you’re unsure which size to pick, it’s generally better to go larger—too big is rarely a problem, while a box that’s too small can limit colony growth and reduce long-term success.
Some bat houses attract residents within a few weeks, but on average it takes 2–6 months. Larger houses can take up to two years to host a colony.
Location is key: place the box near water, in an open, sunny area, and at the correct height (15–20 feet / 4.5–6 meters). Bigger houses often fill more quickly once discovered, since they offer multiple roosting options. If in doubt, choosing a larger model improves your chances of attracting and retaining bats.
Yes—bats are highly effective insect predators. A single bat eats thousands of mosquitoes and crop pests each night, making them natural, chemical-free pest control. Unlike insecticides, which can harm pollinators and other wildlife, bats target insects while supporting biodiversity.
Installing a bat box reduces pests and helps conserve bat populations, many of which are at risk from habitat loss. Larger bat houses also encourage bigger colonies, which means more effective pest control for your property.
