Fleas are a common problem for both pets and humans. One of the most common questions people have is whether or not a dryer kills flea eggs.

The answer is yes- a dryer will kill flea eggs.

Interestingly, flea eggs can survive 95°F (35°C) temperatures. So if you’re looking to kill all the eggs, you’ll need to raise the temperature to at least 113°F (45°C).

The high heat and dryer cycle will kill adults, larvae, and eggs.

However, it is important to remember that female fleas produce up to 50 eggs a day; therefore, incorporating additional steps to eliminate fleas can prove beneficial.

Will Putting Blankets in the Dryer Kill Fleas?

Including blankets, clothes, and linens in the dryer is a great way to get rid of fleas.

In fact, anything that can be washed and dried safely should be put in the dryer with high heat settings for at least 20 to 30 minutes.

As adults, fleas die at temperatures below 46.4°F (8°C) and above 95°F (35°C). The eggs and larvae of these insects are more susceptible to the cold than adult fleas, dying at temperatures lower than 55.4°F (13°C).

The dryer’s heat can kill fleas, but it is still necessary to wash clothes first to ensure that all fleas are eliminated completely.

As a matter of fact, cleaning the clothes beforehand ensures that the fleas will die.

This is because they are first exposed to the heat of the washer (not to mention the rigorous washing and spinning) before being exposed to the dryer’s high heat.

It proves to be a double blow for fleas, ensuring that very few will survive.

Furthermore, just because the dryer kills all the fleas on your clothes or bedding doesn’t mean they are thoroughly cleaned.

If you find fleas in something, it must be washed thoroughly.

Remember, fleas can be difficult to get rid of, so it is important to take every precaution possible.

Do Dryer Sheets Repel Fleas?

There are a variety of methods people use to try and get rid of fleas on their pets. One popular method is using dryer sheets.

Some believe that the scent of the sheet will deter fleas, but there is no concrete evidence to support this claim.

And while it is tempting to use dryer sheets as a DIY flea repellent, the limited success is not worth the danger to your animals.

The chemicals in dryer sheets can be harmful and may even kill your pet.

Will a Hair Dryer Kill Fleas?

Hairdryers would have to achieve temperatures above 95°F (35°C) to kill fleas, just like fleas in the dryer. There are hairdryers that can achieve those temperatures.

However, it would not be easy to hold the dryer in place for an extended period to achieve this.

You can also use other methods to get rid of fleas, such as throwing everything in the dryer and letting it do the work.

Can fleas drown in the washing machine?

Fleas can be removed from clothing by washing them thoroughly.

Nevertheless, as fleas are unlikely to drown in the washing machine, their elimination is attributed to heat and laundry powder’s deadly, dual-action.

Furthermore, fleas can survive in water for up to a week.

This means that if you throw your clothes in the washing machine with fleas on them, the fleas will not die.

You will need to use hot water and detergent to kill the fleas.
