Our pre assembled Three Chamber bat house saves time
We have assembled all the critical elements of the box, including the roof and the interior crevices. The exterior is tough 1/2'' thick plywood with all seams glued and sealed. Our decorative bat design on the front is actually a vent that helps prevents bats from overheating.

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. This box should be painted appropriately for your area, and generally plan on black or a shade of brown (see color chart for your area). Minimal caulking is recommended to finish the roof, then the landing screen and roofing shingle should be attached. Includes 16-page manual with complete finishing, site determination, installation, and maintenance instructions.

Approved by Bat Conservation International. Created and built in Pennsylvania. A pole mount is suggested if placing this box on a post. This bat house has been built as a demonstration during Bat Conservation International's annual Bat Conservation and Management Pennsylvania Workshop each year since 2002.

How to finish this bat house:
1. Paint or stain a color according to your climate (see manual). Use 3 or more coats.
2. Use adhesive to caulk around the roof, and then glue on the included roofing shingle. You may add a tube of exterior grade adhesive to your order at checkout to save a trip to the hardware store.
3. Screw the bat house to the pole mount and a 4''x6''x16' post (~$35 at local lumber yards) cemented 3' into the ground, or attach to the sunny side of a structure. Metal telescoping poles sold by bird house vendors are too flimsy for any of our bat houses.
4. Use the remaining adhesive to coat the upper mounting lip of the bat house that will be exposed to weather
5. Touch up the paint and just add bats!

Above: Our houses use thicker lumber 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 laborously roughened interiors for the ideal bat roost.

Right: size comparison between our 4- Chamber bat house (finished black) and an unfinished 3- Chamber bat house.
