I’ve had this problem before and I take the total war approach. I bathe all animals with an anti flea shampoo, followed by flea combing a few hours later. Then a topical OTC that you apply to the shoulder blades. Also get some flea powder and put down on animal beds, rugs, carpets etc. I also spray the yard with an anti flea treatment…hooks up to the water hose.
If they get established inside then you’ve got issues…go to war with them as soon as you see signs. Good luck bro.[/quote]
We went through this last fall with out cat. Took cat to Petco for a dip, flea powder all over the house, on the couch, beds, etc., vacuumed it up. This didn’t get rid of them.
Took the cat for a 2nd dip at the vet, called our exterminator. He came in with something, walked through the house spraying everything, came back a week later and hit it again. Did around the house as well, no more fleas.
So far so good, we get a 5-month supply of the flea treatment and apply it each month, works very well.
