Bed bugs are tough, but they have one fatal weakness: heat. They die when exposed to temperatures above 118°F (48°C) for a sustained period. Your dryer, my friend, can hit 140°F or more. That’s not just a sauna—that’s an inferno for them.
Think of it this way: a bed bug’s exoskeleton can’t handle extreme dry heat. It literally cooks them from the inside out. And the best part? No chemicals, no sprays, no toxic fumes. Just hot, dry air that you already have.
This method is also a lifesaver for items you can’t wash, like pillows, plush toys, or that expensive coat. Seriously, imagine tossing your favorite cashmere sweater into the wash? Nightmare. But the dryer? Safe.
The Golden Rule: High Heat for 30 Minutes Minimum
Here’s the trick that most people get wrong. You can’t just toss everything in for a quick 15-minute fluff. That’s like giving the bugs a warm hug. You need to run the dryer on the highest heat setting for at least 30 minutes.
Set a timer on your phone and don’t cheat. I know, it feels wasteful on electricity, but consider the alternative—a full-blown infestation. You’d rather pay for that extra cycle than a $2,000 exterminator bill, right? I thought so.
But here’s a pro tip I learned the hard way: Don’t overload the dryer. Air needs to circulate. If you cram it full of jeans and towels, the center stays cool, and the bugs just laugh at you. Do two small loads instead. They’ll be dead before they can giggle.
