A dog with fleas came to my house. Do I need to fumigate it?

Updated On September 23rd, 2025

Pet's info: Dog | Cavalier King Charles Spaniel | Male | neutered | 17 lbs

My dad has a flea investation at his house. We took his dog to the groomers today and the vets for treatment f and then brought him to my house so we can get his house fumigated. Tonight I have seen some fleas still on dads dog alive. I have a dog but he has regular flea treatment at the vets which is up to date. My question is do I now need to fumigate my house too? I'm mortified we have now brought them to mine. Thank you in advance for your assistance.

If the dog was treated prior to coming to you house then the fleas are likely dying. It somewhat depends on what treatment the dog was given as to how much of a problem these fleas may be. I would make sure to keep your dog current on flea medication. Vacuum areas where your dad's dog has been and empty the canister outside as this may pick up an flea eggs or larvae that fell off of that dog. More than likely your house will be fine without drastic treatments. Be sure all pets have flea medication applied or given.
