I looked in the attic but I could not see any evidence of a bat. Then the following night I heard the scratching in the attic in a different area. So I went back up and looked around in the area but saw nothing again. I set mouse traps throughout the house and no luck with that. My house is only 9-10 yrs. old and I looked around outside for an opening to get in and the only opening is the tiny crack in mt sofit right next to the canned lights. Other than that I found no openiings. Is there any kind of a trap I can put in my attic to catch the bat????
