My cat had probably similar fleas brought into our house, I then bought the 2-pack Fogger here - and am very satisfied! Within half a day my flea problem was solved! Because this application is also a bit longer ago, and I've seen so far no more fleas - TOP PRODUCT! Can only recommend this! Is for spaces intended to 30sqm, practically the double because it is purchased directly for two rooms here! ***** - STARS! Price / quality is great!
