3. Dish Soap
“A bath with dish soap would likely remove any fleas that are currently on your pet,” says Abby Bowers, DVM, a veterinarian at the Risius Family Veterinary Service in Iowa. “Unfortunately, there are two big problems with the dish soap method of flea treatment.” The dish soap will dry out your pet’s skin and will only remove the fleas currently attached to your pet (at best).
“The problem here is that adult fleas (what we see on your pet) are only 5% of the flea population in your house,” says Dr. Bowers. “The other 95% is in the environment (carpet, bedding, furniture) as eggs, larvae, and pupae… This means that the dish soap won’t do anything for 95% of the flea population in your house. It’s impossible to get ahead of fleas with baths.”
