i have tried everything and have spent over a 1000 dollars over 4 months. did it by the directions and used more applications than recomended inside and outside. i did a couple hundred feet around my house, in the garage , under sheds, everything. i have used a couple hundred dollars of archer and nygard inside and out. termidor worked best in garage and under sheds but i still have a few fleas outside. i have i cat outside and he is treated monthly and thats works good. i finally used seven dust and borax inside and that is working far better than all the fancy products i used.
