Bedbug Heat Treatment

Bedbugs are a hitchhiking problem, not a housekeeping problem. They arrive on luggage, second-hand furniture, an overnight bag or a work bag, and they settle into a spotless house as readily as a cluttered one. By the time most people notice the bites, the bugs have usually moved well beyond the mattress and into the frame, the headboard, the nightstand and the baseboards.

That spread is what makes them so hard to spray your way out of. Bedbugs shelter in seams, screw holes, joints and voids barely thicker than a business card, and their eggs are cemented in place where most contact products never reach them. Heat gets around that problem: rather than hunting down every hiding place, we make the whole room lethal at once.

How heat treatment works

We bring commercial electric heaters and high-output fans into the space and take the entire room — air, furniture, mattress, wall voids, flooring and belongings — up to roughly 120 to 130°F. The fans matter as much as the heaters. They drive the hot air down into the cracks and crevices where the bugs actually sit, instead of leaving you with a hot room that still has cool pockets inside it.

Temperature probes go out around the room, the cold corners included, and we hold the target until the readings show every part of the space has been there long enough. Heat kills bedbugs at every stage of life, and unlike most chemical work it takes the eggs at the same time — so there is no second hatch to sit and wait out.

What treatment day looks like

Plan on a full day. We work through the house a room at a time, holding each one at temperature for about an hour before moving on, so how long the job runs comes down to how many rooms are involved. We stay with the readings the whole way through rather than setting a timer and stepping out.

Heat is the heavy lifting, but it is not the whole job. We also work an insecticidal dust into the outlets and switch boxes, where bugs shelter and heat is slowest to reach, and treat around the house with a product labelled for bedbugs. Heat clears what is in the room on the day; the dust and the labelled treatment are what deal with anything sheltering outside it.

What you need to do first

Some of the preparation is on you, and it matters. A few things simply cannot stay in a room that is about to reach 130°F:

• Pets and fish tanks, along with every houseplant
• Aerosol cans, lighters and anything else pressurised or flammable
• Candles, crayons, cosmetics and anything else that melts
• Medication, and any wine or spirits you care about
• Records, instruments and similar heat-sensitive belongings

All clothing, bedding and linens have to go through a hot dryer cycle and then straight into sealed bags before we arrive. That one is not optional — it is the step that most often decides whether a treatment holds. Past that, leave the room as it stands — we would far rather treat your furniture where it sits than have it carried through the rest of the house.

Signs you have bedbugs

• Bites in rows or small clusters, usually on skin left uncovered overnight
• Rust-coloured or inky spotting on sheets, mattress seams and the box spring
• Pale shed skins and pepper-like specks in seams and along the frame
• A sweet, musty odour in a heavily used room
• Live bugs — flat, reddish-brown, about the size of an apple seed
