Is bed bug heat treatment worth the price?

Heat and chemical treatments can both clear bed bugs when they are done properly. Which one is worth it depends on your home, your timing and what each quote actually includes, not on the price alone.

It can be, but price alone will not tell you. Neither method is a con and neither is magic. A big gap between two quotes is sometimes fair and sometimes not, and you can only tell once you know what each one covers.

And if the laundry alone has you overwhelmed: you do not have to do it all tonight. A good company tells you exactly what needs doing before each visit, and what can wait.

How heat and chemical treatments differ

Heat. The company brings in heaters and raises the temperature of the room, or the whole home, high enough and for long enough to kill bed bugs and their eggs. They should check it with sensors in the places that heat up slowest. It is often done in one long day. Some things have to come out first because heat damages them, and the company should give you that list. Heat leaves nothing behind afterwards, so some companies add a treatment to cracks and edges to catch bugs that walk back in.
Chemical. A technician treats seams, bed frames, skirting, furniture joints and cracks, often with more than one product. It usually takes more than one visit, spaced out so eggs that hatch after the first visit are caught by the next. Preparation tends to be heavier. You normally sleep at home between visits, and that matters: bed bugs come out to feed and cross the treated surfaces.
Mixed approaches. Many companies combine steam, vacuuming and sprays, or heat with a follow-up spray. Ask what they use and why.

What the price does not tell you

A cheap quote can be one visit to the bedroom with no follow-up. A dear one can cover the whole home, every return visit and a final check. Those are not the same job. Before you compare numbers, get each quote broken down in the same way.

Questions to ask every company

Which method, and which rooms? The bedroom only, or every room where someone sleeps or sits for long?
How many visits are included, and how far apart?
What do I need to do before each visit? Ask for it in writing, so you are not guessing with bin bags at midnight.
When can we sleep at home, and when can children and pets come back into treated rooms?
What happens if we still see bed bugs afterwards? Is a return visit included, and for how long?
How will we know it worked? A good answer includes interceptors or monitors and a check visit, not just “you should be fine”.
Are you insured, and who will actually do the work?

Then line the written answers up side by side: method, rooms, visits, follow-up, what is left out. That is your like-for-like comparison. If a company will not answer them clearly, that tells you something too.

Which one fits your home

Heat often suits a household that needs it done quickly, cannot face weeks of visits, or has bed bugs spread through sofas and soft furniture.
Chemical often suits a smaller problem caught early, or a flat where the building may need treating together, or belongings that cannot take the heat.
The council. In the UK some councils treat bed bugs, often for less, and some no longer do. Ask them the same questions as anyone else and compare what is included.
If you rent, tell your landlord in writing before you book. Who pays depends on your contract and where you live. See who pays for bed bugs in a rental.

Kids, pets and health: ask exactly when children, pets and anyone pregnant or with asthma can go back into treated rooms, and follow what the company and the product label say. Fish tanks and small pets in cages need a plan before the visit, not on the day.

The laundry, one bag at a time

Bag fabrics in the room they are in, seal the bag, and carry it straight to the machine. Wash on the hottest setting the fabric allows, then tumble dry on high heat. The hot dryer is what does the work. Clean things go into fresh sealed bags and stay there until the treatment is finished.

You do not need to throw things away to make the treatment work. Ask the company before you bin anything, and see whether the mattress has to go (usually it does not).

After you have paid

Put interceptor cups under each bed leg and check them on the same day each week. Write down what you find. If they keep catching after the course is finished, call the company back with your dated notes. Our page on bed bugs after treatment covers what to ask next. The bed bug guide has the full plan.
