We recently had two cats who we let in and out of the basement. They got around another cat outside and brought fleas in. We set off flea bombs, put powders on the furniture and carpets, sprayed, vacumned, steamed cleaned and had a professional come in. I had gotten flea traps and he looked at them and said there were only gnats on the one upstairs but some in basement. He said not to vacumn for a week but everywhere i look online says to vacumn everyday. Does anyone have experience with fleas and what the best way is?
