Batproofing


Walls

Fiberglass insulation blown into spaces occupied by bats has been reported as an effective repellent (Scott 1963). Newer types of wall insulation such as rock wool may be blown in through holes bored in the wall; however, if urea formaldehyde is used, extreme caution must be exercised as previously discussed. This must not be done while bats are present to prevent their death and decomposition.
