Ever tossed your sheets, clothes, or blankets into the washing machine hoping to zap those pesky bed bugs away? You’re not alone. The question buzzing in the minds of many: Does washing machine kill bed bugs? Well, it’s not just about throwing things in and hitting start. If you’ve ever dealt with a bed bug invasion, you know the stakes—it’s not a casual spring clean; this is a calculated strike. Let’s break down what really happens behind that spinning door.
How Temperature Influences Bed Bug Survival in Washing Machines
The science is pretty straightforward. Bed bugs are hardy creatures, but they have a kryptonite: heat. Washing clothes in water at least 60°C (140°F) significantly increases the chance of exterminating these pests. Lower temperatures? Forget it. Bugs and their eggs might hitch a ride to your dryer still alive.
- Cold or warm water: Usually ineffective.
- Hot water (≥60°C): Kills bed bugs on contact.
But it’s not just the water temperature; the drying cycle adds a critical second punch. Running your dryer at a high temperature for at least 30 minutes after washing ensures any remaining bugs or eggs face a fatal heat blast.
Why Washing Alone Isn’t Enough
So, flipping on the washing machine isn’t a magic wand by itself. Bed bugs can cling stubbornly to fabric folds, seams, and thick materials like mattresses or cushions. Plus, eggs can be nestled deep inside, not easily drowned or washed off. That’s why mechanical action paired with hot water and thorough drying is key. Even the most powerful spin cycles can’t zap all the pests unless combined with heat.
Putting It All Together: The Best Washing Machine Practices To Kill Bed Bugs
- Sort infested laundry with care—avoid shaking the items to keep bugs from spreading.
- Use the hottest water setting your fabric can handle safely.
- Choose a heavy-duty washing cycle to agitate fabric thoroughly.
- Immediately transfer washed items to dryer; don’t let bugs re-establish themselves on unused clothes.
- Run the dryer on high heat for 30+ minutes to finish the job.
Can Bed Bugs Survive The Washing Machine?
If you saw one cling to a fabric seam after washing, you’d swear they’re invincible. The truth? They aren’t—but only if you follow hot water plus drying protocols. Evidence from experts confirms washing machines alone, especially on cooler cycles, won’t cut it. For detailed guidelines, the Green Shield Pest Control page provides a thorough breakdown of why temps and drying matter.
Extending Protection Beyond The Washing Machine
Washing and drying are battlefronts in your war against bed bugs, but don’t stop there. Consider treating mattresses, furniture, and luggage. Bed bugs embed behind baseboards and inside cracks where your laundry can’t reach. Integrated pest management combining chemical treatments, encasements, and vigilant hygiene delivers a knockout blow.
Don’t Skip These Precautions
- Regularly inspect infested areas even after laundry treatment.
- Seal cracks in walls and furniture.
- Avoid bringing infested items back untreated.
- Consult certified pest professionals for severe infestations.

Common Mistakes With Washing Machines And Bed Bugs
People often trust their machines with low-heat cycles or simply rinsing and praying for the best. That’s a rookie mistake. Bed bugs are survivors of primitive times—they endure cold, water, and starvation longer than you’d think. The stakes are higher in 2026, with bed bugs reportedly developing resistance in some regions. So, no shortcuts. And remember to always dry thoroughly. The dryer is your secret weapon.
When To Call In The Pros
If your bed bug invasion feels like a scene from a horror flick despite diligent laundry efforts, professional pest control is non-negotiable. They have tools and knowledge beyond household appliances. Visit reliable sources like the Purdue University Bed Bug Control Guide for expert insight on professional treatments.
Summary: Does Washing Machine Kill Bed Bugs?
Bottom line? Yes, but only under the right conditions. Washing machines can kill bed bugs if you use hot water (60°C or more) coupled with a high-heat drying cycle. Anything less risks spreading the infestation or leaving survivors behind. Pair laundry with comprehensive pest control efforts for 2026’s tougher bed bug strains.

Frequently Asked Questions
What water temperature kills bed bugs in the washing machine?
Hot water at 60°C (140°F) or higher is needed to kill both bed bugs and their eggs during the wash cycle.
Can bed bugs survive cold or warm water washing?
Yes, bed bugs can survive in cold or warm water. These temperatures aren’t lethal, allowing bugs to potentially re-infest.
Is drying clothes enough to kill bed bugs?
Drying clothes at high heat for at least 30 minutes after washing is critical. Heat from the dryer kills any remaining bugs and eggs.
Can washing machine alone eradicate a bed bug infestation?
No. Washing machines and dryers only treat clothing and fabric items. Infestations in mattresses, furniture, or walls require additional pest control measures.
How often should I wash infested items?
Wash infested items immediately and then regularly during a bed bug treatment period until signs of pests disappear.
Are there fabrics that washing machines can’t safely treat for bed bugs?
Delicates and non-washable items may require alternative heat treatments or professional cleaning to avoid damage.
