Can You Drown Fleas?

Fill the bathtub or sink with warm water and immerse your pet's entire body to drown the fleas. Some will make their way up to the neck trying to escape the water and get trapped in the suds and die. Make sure to rinse your pet thoroughly.

How long does it take for a flea to drown?

Fleas can survive for up to 7 days when dropped in water. When submerged, it takes fleas at least 24 hours to drown. Adding a couple drops of dish soap to the water will speed up the process.
