Leave chickens out of coop for the day. Spray Home Defense along the floor edges and a few inches above. Spray around window sills and doors. I am sure they made Home Defence (Ortho) for Floridians, LOL. My shed stays roach free for a year. The other coop does not have a problem with the big girls in there. I also spray my tool cabinet, and the thresholds on my Lanai, and around the perimeter. No bugs there either. All bugs have to do is walk across it. Lasts a year, and is pet-okay when dried.
