The basic process
- Inspection confirms activity and identifies the areas to treat
- Heat-sensitive belongings are removed and the space is prepared
- Professional heaters and fans raise and circulate air temperature
- Sensors monitor temperature at multiple points, including inside furniture
- Temperature is held for a sustained period, then the space is cooled and checked
Equipment used
Companies use commercial electric or propane heaters, high-volume fans to move heat into voids and furniture, and remote temperature sensors placed where insects harbour. Consumer space heaters cannot reproduce this and can be a fire risk.
Preparation
- Remove aerosols, pressurised containers and flammable items
- Remove medicines, cosmetics, candles, vinyl records and similar heat-sensitive goods
- Remove or protect certain electronics and musical instruments as instructed
- Open drawers and wardrobes so heat can reach voids
- Plan for people and pets to be out of the property for the day
Treatment duration and monitoring
A treated area usually needs most of a working day: time to reach temperature, a sustained hold period and a controlled cool-down. Larger or multi-room jobs take longer, and companies may treat in stages.
Advantages and limitations
Heat treatment does not guarantee elimination in every circumstance. Insects in adjoining units, unreached voids or reintroduction after service can all allow activity to continue.
| Advantages | Limitations |
|---|---|
| Treats all life stages in the heated space | No residual protection after the space cools |
| Belongings are often treated in place | Heat-sensitive items must be removed |
| Concentrated into a single treatment session | Requires substantial preparation and access |
| Reduces the amount of product applied indoors | Cold spots or unreachable voids can reduce effect |
Heat compared with chemical treatment
The two approaches solve different problems and are frequently combined. The structured comparison guide sets out preparation, timing, follow-up and property considerations side by side.
What affects heat treatment pricing
- Square footage and the number of rooms heated
- Property type, access and available power supply
- Severity and whether adjoining spaces must be treated
- Equipment and crew time required on site
- Whether monitoring or a second session is included
Frequently asked questions
Do I have to leave during heat treatment?
Yes. People and pets must be out of the treated area for the whole session and until the company confirms re-entry.
Will heat damage my belongings?
Most household items tolerate the process, but heat-sensitive and pressurised goods must be removed beforehand. Follow the company's written preparation list.
Is one heat session always enough?
Not always. Follow-up inspection or monitoring is standard, and a second session is sometimes recommended depending on what is found.
