Please be aware that there are many companies that offer bat exclusion services that do not follow proper and humane protocols for bat removal and/or charge outrageous prices to exclude bats from buildings. Please visit Merlin Tuttle's Bat Conservation website or the Bat Conservation International website to understand these protocols in order to accurately judge any information forwarded by exclusion companies. Bats should never be excluded from buildings during the reproductive season (May through August) as this will entomb baby bats away from their mothers, ending in certain death.  Because bats do not hibernate in buildings in Colorado, bat proofing a structure can take place in late fall to early spring (October through February) when the bats are hibernating in underground caverns in the mountains.  In addition, CBS strongly encourages placement of bat houses with any exclusion event to give the bats a home when they return in the spring.

Listed below are ethical companies to contact for bat removal. A do it yourself guide to bat-proofing a building as well as bat house plans and installation procedures can be found on the Bat Conservation International website listed below.
