Our pre assembled
Four Chamber Premium Bat House

This premium bat house is an upgrade in size and style over our successful 3- Chamber bat house. It is not just the increased capacity and cosmetic changes that is different; bats have been shown to prefer roosting in larger structures, probably since the larger mass tends to buffer nightly temperature extremes. This means our 4-Chamber bat house is even more likely to be successful than our well-regarded 3-Chamber design. BCM created our own custom mold so that finally a functional and attractive bat house exterior can be made from a durable plastic material. This eliminates the worries that seams will separate over time which will render all wood bat houses unattractive for bats.


No drilling or screw driving is required except when mounting to a post or building. Each interior surface has been permanently roughened by hand in various directions for the best "batholds" possible. We DO NOT use screen material for baffles as it has been shown to shred over time and pups can become trapped under it. Our decorative bat design on the front is actually a vent that helps prevents bats from overheating. Your 4- Chamber Premium bat house is shipped fully assembled without any painting required. Choose a dark color for most northern state and high elevations, or sand color for warm climates (see color chart for your area). Includes 16-page manual with complete finishing, site determination, installation, and maintenance instructions.

Created and built in Pennsylvania. A pole mount is strongly suggested if placing this box on a wooden 4''x4''x16' or 4''x6''x16' post cemented 3' into the ground. Three color selections are available: Black, Green, and Sand.


How to finish this bat house:

1. If mounting on a post, bolt a pole mount to a 4''x6''x16' post (~$35 at local lumber yards) then attach the bat house to the pole mount using exterior deck screws. Then cement the post 3' into the ground. Metal telescoping poles sold by bird house vendors are too flimsy for any of our bat houses.

2. If mounting to a building, attach to the sunny side of a structure but be careful not to have it shaded by roof overhangs. We still suggest scrap 2x4 lumber to use as spacers may help attach the flat bat house to uneven surfaces.

3. Say "Just add bats!"

BCM bat houses are designed and built by bat experts in Pennsylvania. Our houses use thicker lumber our durable plastic shells to outlast competitors, keep bats longer in season, and provide more reliable longer term roosts. Our interiors do not have loosely installed screens that can become deathtraps for bats nor do they just have just a few saw grooves for footholds. BCM bat houses feature one of the most laboriously roughened interiors to create the ideal bat roost.
