- Use hot water at a minimum of 100°F (38°C) and ideally 60°C (140°F) to kill fleas, eggs, and larvae.
- Wash and tumble-dry all pet and human bedding every 1-2 weeks during infestations.

Feeling overwhelmed by a flea problem? You’re not alone — and yes, washing bedding to kill fleas absolutely works! When my dog Bella brought home fleas last spring, I quickly learned that the washing machine became my new best friend. This friendly, practical guide walks you through how to get rid of fleas using your washer, some everyday items, and a little elbow grease. Let’s dive in together.
Why Washing Bedding to Kill Fleas Works
Hot water is a flea’s worst enemy — they can’t survive temps above 95°F. Set your washer to at least 100°F (38°C), preferably 60°C (140°F) or higher, and follow with a high-heat drying cycle to wipe out adult fleas, eggs, and larvae. Ensure all sheets, comforters, pet beds, and throw blankets are washed thoroughly.
But laundry alone won’t solve everything. Flea eggs and larvae love to hide in carpets and corners, so think of this as one part of your overall flea-fighting plan. [INTERNAL_LINK: How to Keep Your Mattress Clean and Flea-Free]
Wondering if your washing settings are hot enough? Learn more about whether 60°C is sufficient to kill fleas on bedding and clothes.

Early Signs of Fleas and What to Do First
- Pets scratching more than usual
- Red or irritated skin, sometimes with hair loss
- Small black specks (aka flea dirt) in fur or on furniture
Fleas don’t just stay on pets — they can linger on your sheets and clothes too. Read how fleas survive on clothing and what you can do about it.
Start simple: wash all soft items, run a flea comb through your pet’s fur, and give them a bath with mild soap. A light spray of diluted apple cider vinegar on bedding can also help repel fleas — just don’t spray it directly on pets with cuts or sensitive skin.

How to Handle a Full-Blown Flea Invasion
- Treat Your Pets: Visit your vet for oral or topical flea treatments.
- Use Flea Control Products: Try sprays, shampoos, or collars — but always read the labels first.
- Call in the Experts: Professional pest control can provide long-lasting treatments and spot hiding places you might miss.

Flea-Transmitted Diseases You Should Know
It’s not just about the itching — fleas can bring along some unwanted guests. They’re capable of spreading diseases like typhus and even plague (yikes!). Most commonly, pets can get tapeworms by swallowing infected fleas while grooming. Staying ahead with prevention means you can protect both your pet and your peace of mind.
