Will Fleas Die in the Washing Machine?

Yes, fleas may die in the washing machine under certain conditions. Fleas are small insects that can infest your pets and living spaces.

When you wash infested items like pet bedding, blankets, or clothing in a washing machine, the high water temperature and agitation can kill fleas and their eggs.

Here’s how you can increase the chances of killing fleas in the washing machine:

  1. Use Hot Water: Washing items in hot water (at least 140°F or 60°C) effectively kills fleas and their eggs. The heat will help destroy the insects’ outer protective layers, causing them to die.
  2. Use Detergent: Adding detergent to the wash cycle can further break down the fleas’ defenses and facilitate their removal.
  3. Long Wash Cycle: A longer wash cycle with adequate agitation will help ensure that fleas are thoroughly washed away.
  4. Drying: After washing, drying items in a hot dryer can also kill any remaining fleas or eggs. High heat is not conducive to their survival.

It’s important to note that while washing infested items can help control the flea population, it might not eliminate the problem if your pet and living space are heavily infested.

Combining washing with other flea control measures, such as treating your pets with flea preventatives and using environmental treatments like flea sprays, will effectively eradicate fleas from your home.

What Can You Add to Your Washing Machine to Kill Fleas?

There are a few things that you can add to your washing machine to help kill fleas.

One is to use white vinegar. You can add a cup of white vinegar to your wash cycle along with your regular detergent. The acidic nature of the vinegar will help to kill the fleas.

Another thing that you can try is adding a package of Borax powder to your wash cycle. This will also help to kill the fleas and their eggs.

You can also try using an outdoor Flea and Tick spray on your clothing before putting them in the washing machine.

This will help to kill any fleas that may be on your clothing. Finally, make sure that you are using hot water when you wash your clothes. Fleas prefer cooler temperatures, so the hot water will help to kill them.

Will Fleas Die in the Dryer?

Yes, the high heat of a dryer will kill fleas. However, it’s important to note that not all fleas will be killed in a single drying cycle.

It’s also important to keep in mind that while a dryer is an effective way to kill fleas, it’s not always the most practical solution, especially if there are pets or small children in the home.

Another thing to consider is that the hot air from a dryer can be damaging to fabrics, so it’s best to use a lower heat setting whenever possible.
