Hot Bugz on Heat Treatment vs. DIY Steam and Clothes Dryers

When people find bed bugs, most of them strip the bed and run everything through the dryer. That’s a good instinct, and it’s part of what we ask customers to do before a treatment. After more than 16 years of heat extermination work across Denver and the Front Range, the team at Hot Bugz hears one question constantly: can a steamer and a hot dryer handle this alone? They can kill the bugs they touch. The problem is everything they don’t touch.

What temperature kills bed bugs and their eggs?

Bed bugs die when they’re held at roughly 120°F or higher for long enough. The U.S. Environmental Protection Agency recommends heating infested items or rooms to at least 120°F for 90 minutes to make sure eggs are killed, and notes that hotter temperatures shorten that time.

Exterminators call this the thermal death point, the temperature an insect can’t survive. What counts isn’t the thermostat reading. It’s the temperature inside the mattress seam, behind the baseboard, and in the screw holes of the bed frame, because that’s where bed bugs live.

Does putting clothes in the dryer kill bed bugs?

Yes. The EPA says a household dryer on high heat for 30 minutes kills bed bugs and eggs in clothing, bedding, and other items that can take the heat. Washing alone often isn’t enough.

The Virginia Department of Agriculture’s heat guide calls for a loosely filled dryer, and comforters or pillows need extra time to heat through. Carry laundry to the machine in a sealed plastic bag, then store clean items in a fresh one.

The limit is simple: a dryer only treats what fits inside it. The couch, box spring, nightstand, and carpet edge stay as infested as they were.

Can a steamer get rid of bed bugs on its own?

A steamer kills bed bugs on contact when used correctly, but it only treats surfaces, and correct use is harder than it looks. University of Minnesota and Minnesota Department of Agriculture guidance calls for a commercial steamer holding at least one gallon, with an upholstery or floor attachment. The surface should read 160 to 180°F right after the brush passes, checked with a non-contact thermometer.

A handheld garment steamer rarely meets that standard. Move too fast and the fabric never gets hot enough. A narrow nozzle can blow bugs away before killing them, something the University of Tennessee’s bed bug program has flagged for pest professionals. Steam also cools quickly inside thick materials, so bugs deep in a box spring or dresser joint often survive. Silk and microfiber can be damaged, and burns are a real risk.

Why do DIY bed bug treatments usually fail?

Most at-home efforts fail because they’re partial. You dry the bedding while the bugs have already moved to the recliner. You steam the mattress while eggs sit glued inside the headboard.

Uneven heat can make things worse. Research summarized by the University of Tennessee found that bed bugs heated through a surface began escaping at around 105°F, before reaching a lethal temperature. Slow, patchy heat can push bugs deeper into a room. It’s also why we tell people never to heat a room with consumer space heaters. They won’t get hot enough, and they can be dangerous.

How is Hot Bugz heat treatment different?

Professional heat treats the whole space at once, so bugs have nowhere left to go. A Hot Bugz treatment brings rooms to 135 to 140°F with specialized equipment, and our technicians stay on-site monitoring the entire time.

In that same Tennessee research, bed bugs exposed to hot moving air didn’t try to escape until they’d reached their lethal limit. Air carries heat into mattresses, furniture, wall gaps, and clutter together, and sensors placed in the hardest spots confirm each one reaches the target.

Most treatments take 5 to 10 hours, and you’re home the same day. No pesticides are used, which matters because many bed bugs now resist common insecticides but can’t adapt to heat. Price depends on square footage, infestation size, building materials, and access, so we quote after inspecting. Keeping your mattress and couch instead of replacing them usually closes much of the gap.

Where do the dryer and steamer still fit?

Use them for preparation and prevention. Drying clothes and bedding before a treatment protects those items and clears the room. After a trip, 30 minutes in the dryer for everything in your suitcase is cheap insurance. For an active infestation, though, those tools work the edges while the bugs live in the middle.

Getting rid of bed bugs the first time

A dryer and a steamer both kill bed bugs, but only where the heat lands, and bed bugs are good at living where it doesn’t. Whole-room heat reaches those places in a single visit, without chemicals. If you’re dealing with bed bugs in the Denver area, contact Hot Bugz for an inspection. We’ll show you the live bugs we find, explain how they likely got in, and give you a firm quote before any work begins.
