This is an attract product that is similar to Buck scent deer hunters use to attract deer. Only its for attracting bats to an area you desire. Do not use on Red Cedar, Cypress. PLywood, or any airomatic wood, as the wood needs to air out before bats will move in. That takes apx 2 to 4 years for that type wood. This scent does work on all others or aired out red cedar. etc.
