look up flea busters flea powder it works great and will work for a year, put it in your carpet, around base boards, beds. I had flea probleams after I moved to a condo and was putting flea meds on him every month, then flea busters came out and I rarely find a flea, it is awsome and safer than ditotamaeous earth to use. I rarely use anything on him and comfortis, make sure you give it after they have eaten |
