How Long to Kill Bed Bugs in the Dryer
Adult bed bugs are tough, but their eggs are tiny armor-plated monsters. They can survive at 120°F for up to 90 minutes. Yes, you read that right—an hour and a half.
To kill the eggs, you need 130°F for 60 minutes minimum. So if you’re treating infested clothing, don’t stop after thirty minutes. Let that dryer sing its hot lullaby for a full hour. Trust me, a long cycle now saves you from a second infestation later.
I once thought I’d won after a 30-minute dryer session. Two weeks later, I found tiny nymphs in my sock drawer. I wanted to burn the house down. (I didn’t. But I did buy a steam cleaner.)

Pro tips so you don’t mess up like I did
First, don’t overload the dryer. You need room for hot air to circulate. If you shove in a mountain of laundry, you’ll get a warm, bug-friendly core. Half loads are your friend here.
Second, check the lint trap before starting. A clean vent means better airflow and higher temps. A clogged one? Your dryer might top out at 100°F. Bed bugs will laugh at that.
Third, use a thermometer if you’re paranoid. I bought a cheap oven thermometer and tossed it into a pillowcase once. Reading: 140°F after 15 minutes. That was my “aha” moment. Now I’m a dryer savant.
