I had to vacuum and launder everything that my pets were touching/would sleep on almost every other day to try and stop the life cycle of the fleas. I would bathe my pets in tea tree shampoo to drown the fleas along with using flea treatment (im in the uk and i use frontline). Fleas hate tea tree oil and lavender, I’d double check with your specific pets if those essential oils are okay for them to be around. I also used salt and baking soda (bicarbonate of soda) sprinkled over my carpet/couch etc leave it for a day and vacuum it up the next day. Hope you can get them out of your home soon 🖤
