Chemical-Free Heat Treatment for Insects

Heat treatment is the fastest, most thorough way to eradicate an insect infestation. By raising the temperature of a room and its contents to a level that is lethal to insects, we kill every life stage in a single treatment - adults, larvae, nymphs and the eggs that chemical sprays simply cannot reach.

It is the treatment of choice for bed bugs, fleas, clothes and carpet moths, cockroaches and carpet and textile beetles. Because heat penetrates deep into furniture, mattresses, skirting, cracks and crevices, there is nowhere for the pests to hide. Treatments in your area are carried out and monitored by our RSPH (BPCA) Level 2 certified and trained technicians.

How much does heat treatment cost, and how long does it take?

In most areas, bed bug heat treatment for a one-bedroom flat (bedroom and living room) starts from £929.99 + VAT. That is one heat treatment visit, and most domestic treatments are completed in a single day. Because no insecticide is used, rooms can be used again once they have cooled, usually the same day.

When the whole property is treated, heat treatment is guaranteed for 4 months: if bed bugs come back in that time, we come back within 72 hours of you telling us. Larger homes cost more, and your exact price depends on your postcode and the number of rooms. See how much bed bug treatment costs for the full breakdown.

How Heat Treatment Works

We position professional heaters and circulation fans to bring the whole space up to a controlled, lethal temperature, then hold it there long enough to penetrate right into the contents of the room. Placed sensors let our technicians monitor the temperature throughout, so we know that heat has reached every cold spot - inside the mattress, behind the skirting and down into the cracks and crevices where insects shelter and lay their eggs.

Unlike sprays, which only treat the surfaces they touch and leave residue behind, heat reaches the whole environment at once. It is a single treatment with no chemical residue and a fast return to use.

Frequently Asked Questions: Heat Treatment

Whole-room heat is most effective against bed bugs, where it kills adults, nymphs and eggs in a single visit. It is also used for moths, fleas, cockroaches and textile beetles, and anywhere chemical resistance or sensitive environments make spraying unsuitable.
In most areas, bed bug heat treatment for a one-bedroom flat (bedroom and living room) starts from £929.99 + VAT, for one heat treatment visit. Larger homes cost more, and your exact price depends on your postcode and the number of rooms.
Most domestic treatments are completed in a single day. The room is brought up to the target temperature, held there long enough for heat to penetrate furniture, skirting and voids, then monitored as it cools.
You will need to stay out of the treated rooms while the equipment runs, and our technicians will walk you through simple preparation beforehand. Because no insecticide is used, rooms can be reoccupied once they have cooled, usually the same day.
Heat reaches the eggs and hidden insects that sprays miss, needs no repeat visits in most cases, and leaves no chemical residue. For established bed bug infestations it is the most reliable single-visit option available.
