Handcrafted from cedar and finished in black, this two-chamber habitat holds up to 75 bats. The dark finish pulls in daytime heat and holds it after dark, which is what a colony needs where evenings turn cold.
Two chambers, 75 bats. Bats roost in tight vertical crevices, not open cavities. Two chambers give a colony the depth it needs and a choice of temperature as the day heats up and cools down.
Why the black finish. Black absorbs solar heat and releases it slowly overnight. In cooler regions and at elevation that stored warmth matters more than almost any other design choice. For hot summers, the natural cedar finish reflects heat instead.
Rough-sawn interior. Every interior surface is grooved so bats can climb and hang securely. A smooth interior is the most common reason a habitat stays empty — bats cannot grip it.
Ventilated and weather-resistant. Ventilation slots keep the chambers from overheating on the hottest days and stop damp collecting. Solid cedar resists rot without chemical treatment.
Honest about timing. Bats scout new roosts in spring and are deliberate about it. Some fill in the first season, others take two. Height, sun exposure and distance to water matter most — all three are covered below.
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.
