Treating bedding for bed bugs requires bagging, hot washing, and high-heat drying for at least 30 minutes before sealing the clean items away from re-infestation.
Finding bed bugs in your bedding is an unsettling experience, but getting rid of them follows a clear and effective sequence. The goal is to use high heat to kill both the bugs and their eggs, then isolate the cleaned items so they stay pest-free while you treat the rest of the room.
Bag and Move Bedding Carefully
The first step is preventing the spread. Do not carry loose bedding through your home to the laundry room. Strip the sheets, pillowcases, blankets, and duvet covers directly into a sealed plastic bag. Once the bag is full, seal it tightly and carry it to the washing machine. Double-bag the laundry and discard the outer bag after loading the washer. This simple precaution keeps stray bugs from falling onto floors or furniture as you move through the house.
Does Washing Kill Bed Bugs?
Washing your bedding in hot water is a critical step, but it is the combination of washing and high-heat drying that fully eliminates the infestation. Hot water (at least 120°F or 60°C) will kill many bed bugs and nymphs, but the eggs are more resilient. The dryer, running at a high temperature for 30 to 45 minutes, provides the sustained heat needed to kill all stages of bed bugs, including the eggs. Make sure the dryer is loosely packed so the heat circulates freely through every layer.
After the cycle, the items are safe. Place the freshly dried bedding into a new, clean sealed plastic bag or storage bin to protect it from any bed bugs still active in the room.
| Method | Best For | Key Requirement |
|---|---|---|
| Hot Washing | Bedding and linens | Hot water (120°F / 60°C) |
| High-Heat Drying | Bedding and clothing | 30–45 min, loosely packed |
| Dry Cleaning | Delicate fabrics | Standard cycle |
| Freezing | Small sealable items | 4 days at 0°F (-18°C) |
| Vacuuming | Mattress and furniture | Empty outdoors immediately |
| Steam Cleaning | Mattress and upholstery | Item must tolerate heat |
| Encasements | Mattress and box spring | Leave on for 1 year |
What About the Mattress and Frame?
Treating the pillows and sheets is only half the job. The mattress and bed frame are the primary hiding spots for bed bugs. While the bedding is off, thoroughly vacuum the mattress seams, box spring, bed frame, headboard, and baseboards. The EPA’s comprehensive do-it-yourself bed bug control guide underscores the importance of bagging items before carrying them through the house.
Immediately after vacuuming, empty the canister or bag outdoors into a sealed trash bag. Then, encase the mattress and box spring in a bed bug-proof encasement. These six-sided zippered covers trap any remaining bugs inside and prevent new ones from entering. Leave the encasement on for at least one year to ensure all trapped bugs die.
For an efficient cleanup, having the right tools makes a significant difference. Check out our guide to the best bed bug kit for the top-rated vacuums, steamers, and encasements.
Frequently Asked Questions
How long do I need to keep treating bedding?
Continue washing and drying bedding on high heat at least once a week until you have seen no signs of active bed bugs for several consecutive weeks. Persistence is essential for full control because eggs can hatch weeks after the initial treatment.
Will I have to throw away my mattress?
No, you typically do not need to discard your mattress. Thorough vacuuming followed by installing a bed bug-proof encasement is the standard and effective recommendation for treating an infested mattress.
Can I freeze my bedding to kill bed bugs?
Freezing can work for small items that cannot be washed or dried on high heat. The freezer needs to maintain a consistent temperature of 0°F (-18°C) for at least 4 days for this to be effective.
