I use advantage on my dogs and only use it when I see fleas...once it is administered the fleas are usually gone within days..it lasts for 30 days..I dont reapply it until I see a flea again...I went all last year with no fleas..had to treat them once this month..this is a bad time of year for fleas. Fleas also produce VERY quickly..if you see one there are TONS more..in your carpets and bedding...after you put the advantage on your dogs, wash everything, vaccum and make sure you empty the vaccum bag OUTSIDE..oh and bath before you put on the flea oil...probably wont have fleas for long if you do all that!!
