I’ve been using flea bombs over and over and I don’t think they’re working. Did they change something in the formulation? This year the fleas are so bad I bomb and then like the next day I have fleas again. What’s going on? My cat is staying up on the countertop and I think that makes harder for me and my husband. Funny thing is this year even he is getting bit so it must be bad!!!! What can I do?
