Can You Wash Clothes to Kill Bed Bugs? Expert Advice and Proven Techniques
Yes, you can wash clothes to kill bed bugs, but it’s not just the washing itself that does the trick. The critical element is heat. The heat from the dryer is what eliminates these pests.
The Science Behind Laundry and Bed Bug Elimination
Bed bugs are resilient creatures, capable of surviving for months without feeding. They are notoriously difficult to eradicate, and simply throwing infested clothing into the washing machine, even with soap, won’t guarantee their demise. While the agitation and water can dislodge some bugs, the heat is what truly kills them.
The lethal temperature for bed bugs is approximately 120°F (49°C). This temperature needs to be sustained for a specific period to ensure all bugs and their eggs are destroyed. Washing and drying at high temperatures are powerful tools in your bed bug-fighting arsenal.
Understanding Bed Bug Biology and Vulnerabilities
Before delving into specific techniques, understanding the basic biology of bed bugs is crucial. These tiny, reddish-brown insects feed on human blood, primarily while people are sleeping. They hide in cracks and crevices during the day, often near beds, and are masters of concealment.
Their eggs are even more resistant than the adults. They are tiny, pearly white, and often glued to surfaces, making them difficult to remove manually. Therefore, any eradication method must target both the adults and the eggs.

Washing Clothes: A Step-by-Step Guide
Here’s a detailed guide on how to effectively wash clothes to kill bed bugs:
- Contain the Infestation: Carefully bag infested items in tightly sealed plastic bags before transporting them to the laundry room. This prevents the spread of bed bugs to other areas of your home. Avoid shaking the items, as this can scatter the bugs.
- Choose the Right Detergent: While any detergent will help dislodge bed bugs, using a strong laundry detergent can increase your chances of success. Look for detergents with enzymes or specifically designed for stain removal.
- Wash at High Temperatures: Set your washing machine to the hottest water setting recommended for the fabric, ideally above 120°F (49°C). This is the most critical step.
- Wash for an Extended Period: Run a complete wash cycle. A longer cycle ensures that the water remains hot for an adequate duration.
- Transfer Carefully to the Dryer: After washing, carefully transfer the items to the dryer, again trying to minimize shaking and potential bug escape. Use a clean bag or container to avoid cross-contamination.
- Dry on High Heat: Dry the clothes on the highest heat setting for at least 30 minutes. This is the step that will actually kill the bed bugs and their eggs. Longer drying times are even better.
- Inspect and Repeat if Necessary: After drying, carefully inspect the items. If you see any signs of bed bugs, repeat the washing and drying process.
- Bag Clean Items: Once you are confident that the items are bug-free, store them in clean, sealed plastic bags to prevent re-infestation.
Frequently Asked Questions (FAQs)
Here are twelve frequently asked questions about washing clothes to kill bed bugs:
FAQ 1: What temperature is needed to kill bed bugs in the laundry?
The water temperature needs to be at least 120°F (49°C) to effectively kill bed bugs and their eggs. Ensure your washing machine’s hot water setting reaches this temperature. The dryer should also be set to high heat.
FAQ 2: Can I kill bed bugs by just washing clothes in cold water?
No, cold water washing is not effective in killing bed bugs. While it might dislodge some bugs, it won’t kill them or their eggs. The high heat of the dryer is essential.
FAQ 3: What if my clothes can’t be washed at high temperatures?
For delicate items that cannot withstand high heat, consider dry cleaning. Dry cleaning chemicals are typically effective at killing bed bugs. Alternatively, you can place the items in a sealed plastic bag and put them in the freezer for at least four days at 0°F (-18°C). However, ensure the freezer maintains that temperature consistently.
FAQ 4: Do I need to wash clothes that were just in a room with bed bugs, even if they weren’t on the bed?
Yes, it’s a good precaution to wash any clothes that were in a room with bed bugs, even if they weren’t on the bed. Bed bugs can crawl onto clothing and other items, so it’s best to err on the side of caution.
FAQ 5: Can I use essential oils or special laundry additives to kill bed bugs?
While some essential oils like tea tree oil and lavender oil have insecticidal properties, their effectiveness against bed bugs in laundry is not definitively proven. Rely on high heat washing and drying rather than solely on these additives.
FAQ 6: How do I clean my laundry bag after washing bed bug-infested clothes?
The laundry bag itself can become infested. Wash it using the same procedure as the clothes – hot water and high heat drying. Alternatively, you can dispose of the bag in a sealed plastic bag.
FAQ 7: Can I use my regular detergent when washing for bed bugs?
Yes, you can use your regular detergent. While specialized detergents are available, they are not essential. The high heat of the water and dryer is the key factor.
FAQ 8: How long should I dry my clothes to ensure the bed bugs are dead?
Dry your clothes on high heat for at least 30 minutes. Longer drying times, up to an hour, are recommended to ensure complete eradication, especially for thicker items.
FAQ 9: Is it possible for bed bugs to survive the washing machine and dryer?
While unlikely, it’s possible, especially if the water temperature is not high enough or the drying time is insufficient. This is why it’s important to follow the recommended procedures carefully and repeat if necessary.
FAQ 10: What should I do if I can’t wash certain items, like shoes or stuffed animals?
For items that cannot be washed, freezing is an option. Place the items in a sealed plastic bag and freeze them for at least four days at 0°F (-18°C). Alternatively, consider using a bed bug-specific spray that is safe for fabrics, following the manufacturer’s instructions carefully.
FAQ 11: How often should I wash my bedding if I suspect bed bugs?
If you suspect bed bugs, wash your bedding every few days until the infestation is controlled. This will help to reduce the number of bed bugs and prevent them from spreading.
FAQ 12: Can washing clothes alone get rid of a bed bug infestation?
No, washing clothes is just one part of a comprehensive bed bug treatment plan. You will also need to treat your mattress, furniture, and other areas of your home. Consider hiring a professional pest control company for effective eradication.
