Q. Hi I treated my cats and home with flea products and all seemed to be under control but as soon as they came back frm outside were rddled again

A. Thanks for your question. Assuming you are applying the flea treatment in the correct way, It depends on the flea treatment product you are currently using. Unfortunately some flea treatments that you can buy in the pet stores are not concentrated enough to maintain the effect for long period of time.
I would strongly recommend to buy a prescription product suggested directly by your veterinarian.
