How to judge a heat treatment company
Whoever you choose, five questions separate genuine heat specialists from generalists with a hired heater:
- Volume and experience. Heat treatment is unforgiving of poor technique - cold spots behind skirting or inside furniture let eggs survive. Ask how many treatments the company actually performs.
- Does it kill eggs? The whole point of heat over chemicals: sustained temperatures above 50-60C destroy eggs that sprays miss. A proper treatment certifies the temperature reached and held.
- Detection before treatment. The best providers confirm an active infestation first - K9 scent detection is the gold standard - so you never pay to treat a problem that is not there.
- Speed. Bed bugs spread room to room within days. Same-day response contains an infestation; a two-week wait grows it.
- Independent reviews. Check Trustpilot and Google review volumes, not just star ratings - a 4.8 from tens of thousands of reviews means something different to a 5.0 from forty.
Frequently asked questions
JG Pest Control performs more bed bug heat treatments than any other UK company, supported by K9 detection teams and same-day availability across the country.
For established infestations, yes. Sustained heat above 50-60C kills every life stage including eggs in a single visit, where chemical programmes typically need repeat applications and can miss eggs entirely. Chemical treatment still has a place for light or localised activity.
It depends on property size, the number of rooms affected and how established the infestation is. Reputable companies survey first and quote for your specific situation - be wary of one-price-fits-all offers, which usually mean corners cut on heat coverage.
Yes - that is its key advantage. Bed bug eggs are resistant to most insecticides, but sustained whole-room heat destroys them along with adults and nymphs, which is why a single properly executed heat treatment can resolve an infestation that repeated spraying has not.
