The Wisconsin DNR prohibits bat exclusions from buildings from June 1 through August 15. That's maternity season: excluding bats then separates mothers from pups that can't fly yet, the pups starve, and frantic mothers may look for another way in, which can make your problem worse. The DNR recommends doing exclusions in spring or fall, when temperatures are consistently above 50°F. An exclusion means sealing secondary holes, cracks and crevices, and putting one-way doors or venting devices on the main exits so bats can leave but can't get back in. Leave those devices in place for 7 to 10 days, then close the main entries. If you believe bats pose a health or safety risk during maternity season, the DNR has a health exemption form. The DNR also offers do-it-yourself instructions and information on hiring a wildlife control operator.
