WE HAD A BAT PROBLEM TOO-STILL DO THE PROBLEM IS WHEN THEY GET RABIES OR FIND THEIR WAY INTO THE HOUSE AND ACT STRANGE--CAUSE FOR ALARM HERE. THE BABIES MAY LEAVE THE NEST IN AUG BUT TIL THEM BEST NOT TO DISTURB THEM CUZ THEY MAY GET TRAPPED IN THE SPACE AND DIE THERE CAUSING MORE PROBLEMS. THE GUANO DOES GET FRAGRANT WHEN THE SUN HITS THE WALL THEY ARE HOLED UP BEHIND. SEVERAL BAT INFO SITES CAN BE FOUND ON THE WEB WWW.CDC.GOV (THE CENTER FOR DISEASE CONTROL) http://www.batcon.org http://www.batsnorthwest.org/ http://www.batsnorthwest.org/batsArticle.asp?ID=91
