Got my first flea on me this season in the living room 😭 I treat my (indoor) cats once a month and treat my dog every 2 weeks so no idea how one got in the house.. The powder just seems to fill the air when you use it any safe recommendations on things to use on the carpet? 2 years ago we got fleas and I fought them for probably a month and a half so I know it's just one flea but I am not risking any time! Their gross and it was hell vacuuming 2x a day for 2 months straight plus the smell of the flea stuff 🤢 ugh I really dont want a re run of a couple of years ago i will cry!
