Flushing fleas that are still alive may not kill them for quite some time. It could take 24 hours or longer for fleas to drown in only water. Flushing them down the toilet may keep fleas alive for up to 7 days.

Drowning or flushing a flea is best done when the flea is confirmed to be dead. Also, if you drown a flea first in soapy water like dish soap mixed with warm water in a bowl, they will suffocate with clogged pores.

The reduced surface tension of the water will also make it impossible for the flea to escape.

How Long Does It Take For a Flea to Drown in Water?

Fleas have survived for centuries as lingering pests because of their resiliency. They are not meant to live underwater, but they can stay in it for up to 7 days. A fully submerged flea with no chance to get out of the water should die or drown in 24 hours.

If the water contains pore clogging dish soap as well, the surfactants in the soap with reduce the surface tension and the flea will drop lower into the water and drown.

How Do You Flush out Fleas?

Fleas can be vacuumed and the bag should be tossed out of the home. The further away from your property, the better is it for you to prevent them for returning.

Add some salt, baking soda or boric acid to surfaces around the home to flush out fleas. The aim is to dry them out with these powdery substances.

Will Fleas Jump Into a Bowl of Water?

Fleas don’t want to jump in bowls of water. Adding dish soap will attract them into the bowl. Plain water won’t cut it.

Also, if a flea happens to fall or jump into plain water, they can survive for 24 hours to 7 days. They can get out and continue to look for a host to feed off.

Killing fleas with water alone is not going to cut it. Capturing a flea and simply flushing it down the toilet doesn’t mean the flea is dead. We need to be certain that our efforts are not going to waste.

We should make sure the flea is dead before flushing it. We can do so by squishing the tissue or drowning the flea inside it into a bowl of dish soap mixed with water. Fleas can float and survive for 24 hours to 7 days when they fall in water.

They cannot survive when the surface tension is reduced due to dish soap that ends up pulling them deep down. Fleas will sink and die this way.

It is safe to flush fleas down the toilet, but we should not take the chance that they could jump out of the toilet bowl before we flush. Squish, smash or dunk the flea in soapy water first to make sure it’s officially dead before we say goodbye to them forever.
