BCM Bat Houses Compared

Just a few bats can eat thousands of night-flying insects in a single night, making them the perfect for reducing nasty pesticide use. By eating everything from crop-pest beetles to annoying mosquitoes, bats help keep your garden and your family safe. Simply just having bats nearby actually can drive away some insects!

"Artificial bat roosts" are man-made homes bats move into where they have lost natural habitat. Bats may be found in Bat Houses of course, but also Artificial Bark, Artificial Trees, Bridges, Culverts, Old Buildings, and even purposely built Artificial Caves!

BCM's founder John Chenger helped define all-wood bat houses during his time at the Pennsylvania Game Commission in the 1990's. While these early bat houses were quite successful, it became clear a lack of maintenance ultimately will render all wood-exterior bat houses unusable. A longer-lasting solution was sought. Experiments showed bats preferred wood on the inside of the roost, but the outside could be virtually anything. While we have seen bats move into our bat houses in as little as a few days, the reality is it may take -years- for bats to move in. Therefore it's critical your bat house last as long as possible; many all-wood bat houses are unusable before bats even occupy them, and maintaining (painting) a wooden bat house high off the ground regularly is a challenge. Our Colony-series bat houses and Super Rocket Roost come with an industry-first 10 year guarantee against splitting which typically renders other bat houses unusable.

ColonyCabin

BCM's ColonyCabin 3 chamber bat house features a fully-assembled no-maintenance exterior which will outlast any wood based bat house. It is our least expensive resin bat house, making it more economical to try a few different solar exposures or locations to more likely start new bat colonies in an area. Few people maintain a bat house once installed, so we make ours to last as long as possible; no painting and unlike wood there are no seams to separate. An extra 4th roost chamber offers overheating protection behind the bat house when installed with a mount kits on either a wall or a post. A single ColonyCabin might hold up to ~126 bats and has four colors to choose from.

ColonyLodge

ColonyLodge 4 Chamber features a resin exterior that requires no assembly or painting, and will outlast any unmaintained all-wood bat house. ColonyLodges have different crevice widths and four colors suitable for species found all over North America. ColonyLodges have a larger capacity (up to ~210 bats) than the ColonyCabin but smaller than a ColonyCondo. A 5th roost crevice provides bats with a more ventilated rear space is included with mount kits. ColonyLodges have the traditional "woodgrain bat house look" without the issues inherent with an all-wood bat house. Installation available.

ColonyCondo

Our ColonyCondo 5 chamber is the largest single bat house we offer, comes in four colors, and may hold up to ~260 bats. It features an industrial resin exterior that never needs painting, has no seams that will separate over time, and will outlast any unmaintained wood bat house. A 6th roost crevice provides bats with a more ventilated rear space is included with mount kits. Choose this bat house if you already know you have a bat colony nearby, or perhaps you are mounting on a post in a colder climate, or just want to start big. Ships UPS and can be installed buildings or posts obtained locally. Installation available.

DayLodge

DayLodge three chamber bat houses are totally functional, solid choices. The exterior is plywood, but we've eliminated a lot of fail points found in wood designs. We mount straight thru the front, eliminating stress and seams on the roof. The resin roof is a slab of recycled plastic lumber which lasts decades. DayLodges can be successful on buildings and posts, and is a good a choice to spread out to start new colonies. This is the only kit and mostly wood bat house we offer. Kits are very popular for DIYers and group activities!

Super Rocket Roost

The Super Rocket Roost simulates a dead tree, allowing bats to enter into crevices found under an industrial-quality resin shell. Two styles of crevices are along the extra height of the roost, allowing bats to find just what microclimate they are looking for. It's a different look and style, easy to install, provides bats with more options, and can be successful in all but the hottest regions.

Super Duplex

Merlin Tuttle bugged BCM's founder John Chenger to take advantage of the "empty space" between back-to-back bat houses. John added a second post for stability and a roost cluster that fits between the posts and twin ColonyCondos. The Super Duplex cluster is like three ColonyCondos in one structure, capable of housing ~750 bats. Bats can move between the ColonyCondos and the center roost anytime. These are manageable that ~4 people can stand it up so that it slides into the foundation holes, and one skilled person can do it with truck or tractor loader. Installation is available

Modular Bat Condos

Our observations clearly support that small colonies of bats occupy small bat houses first, and so the modular design of these 2x2 Modular Condo and 3x3 Modular Condo roosts allows individual compartments to heat rapidly. These structures may house ~2000+ bats, which is a good target for "watchable wildlife", as Merlin and John agree there will still be bats emerging from this structure even after it's too dark to see. If more capacity is needed, build another Modular Condo nearby. Several smaller structures protects against catastrophic failure, vandalism, and predators. Modular Condos are somewhat of a special order, delivery+installation are available in certain areas.
