I have a small dog about ten pounds and put advantix on her monthly. We have a small yard 125 x 40. She gets fleas on her daily. Two times last week I sprayed the entire yard with crosscheck from lesco. I vacuum the entire house every other day. I have been giving her flea baths every other day but the problem is getting worse. The last bath had 10-12 on her, some dead, half dead and some still alive. Can anyone help here?
