Thermal Fogging & Larviciding
Thermal fogging uses heat to turn insecticide into a dense, visible fog that spreads across wide outdoor areas, into vegetation, drains and dark corners where mosquitoes rest. Combined with larviciding of breeding water, it quickly reduces mosquito numbers in open spaces.

- Heated fog + larviciding
- Targets
- Adult mosquitoes and larvae
- Best for
- Gardens, open grounds, drains, housing areas
- Often paired with
- Removing standing water
How thermal fogging works
- Inspect
We locate breeding sites and the vegetation, drains and shaded areas where mosquitoes rest.
- Larvicide
Breeding water that cannot be emptied is treated so larvae do not develop into adults.
- Prepare
Windows and doors are closed, and people and pets are kept away from the fogging area.
- Fog
A thermal fogger releases a dense fog that drifts through vegetation and open spaces.
- Report
You get a service report and advice on removing breeding sites.
Pests we use thermal fogging for
Thermal fogging is a mosquito control method for outdoor and open areas:
Preparing for thermal fogging
Before we arrive
- Close windows and doors facing the fogging area
- Bring pets, laundry and outdoor food indoors
- Cover fish ponds and turn off pumps
- Move cars if they are parked in the fogging area
After the treatment
- Wait until the fog has fully cleared before going outside
- Keep removing standing water every week
- Report any continuing mosquito activity to us

Thermal fogging questions
What is thermal fogging?
A method that uses heat to vaporise insecticide into a dense, visible fog. The fog spreads through vegetation and open spaces where mosquitoes rest, knocking down adult mosquitoes quickly.
What is larviciding?
Treating standing water where mosquito larvae grow, so they never develop into biting adults. It is combined with fogging because fogging alone does not stop new mosquitoes hatching.
Thermal fogging or cold fogging?
Thermal fogging suits large outdoor areas and dense vegetation. Cold fogging produces a non-heated fog that suits enclosed indoor spaces. We choose based on your premises.
How often is fogging needed?
Fogging kills the adults present at the time. If breeding sites remain, new mosquitoes appear, so some properties need a regular schedule. We recommend one after inspecting.
Compare treatment methods
We choose the method after inspecting your premises, and many jobs combine two.
Residual Spraying
A long-lasting surface treatment along cracks, drains, skirting and harbourage points that keeps working after it dries.
How it works →
ULV Misting
Ultra-low volume misting that spreads very fine droplets into hard-to-reach spaces, for flying insects and hidden pests.
How it works →
Gel Bait Treatment
Small dots of bait placed in cracks and crevices. Ants and cockroaches carry it back to the nest, treating the colony.
How it works →
Cold Fogging & Larviciding
A non-heated fog for enclosed indoor spaces, with no high temperatures, plus larviciding where mosquitoes breed.
