I caught a flea in my 13-month old’s room and saw another a few days later. She shows no evidence of being bitten (neither does our cat), even though she plays on the floor every day. My husband and I are a different story; even though I’ve only seen two fleas, we have multiple bites. I started vacuuming every other day, treated the (wall-to-wall) carpet with borax, and kept my daughter off the carpet as much as possible. Is there another treatment that is safe for me to use on our floors with a crawling baby?
