Residual Spraying Treatment
Residual spraying applies a long-lasting insecticide to the surfaces where crawling and flying insects hide, travel and enter, such as cracks, skirting, drains and furniture joints. It keeps working after it dries, forming a protective barrier that continues to control pests after the visit.

How residual spraying works
- Inspect
We find where pests hide, travel and enter: cracks, drains, skirting, furniture joints and perimeters.
- Prepare
Food, utensils and personal items are put away or covered, and pets are kept out of the area.
- Apply
A trained technician sprays a targeted, measured amount onto those surfaces, not into the open air.
- Dry
The treatment dries on the surface and keeps working against insects that cross it.
- Report
You get a service report showing what was treated and any follow-up needed.

Residual spraying questions
What is residual spraying?
It is a pest treatment that leaves a long-lasting layer of insecticide on surfaces where insects hide and travel. Insects that cross the treated surface after it dries are still affected, so it keeps working after the visit.
Is residual spraying safe?
It is applied by trained technicians in targeted spots such as cracks, skirting and drains, not sprayed into the air. Keep children and pets away until treated areas are dry, and we will tell you when that is.
How long does residual spraying last?
It depends on the surface, cleaning and conditions. We recommend a follow-up schedule in your quotation based on the pest and premises.
Do I need to leave the house?
Usually only the rooms being treated need to be kept clear until they are dry. We explain what to expect before we start.
Compare treatment methods
We choose the method after inspecting your premises, and many jobs combine two.
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 →
Thermal Fogging & Larviciding
A dense heated fog for large outdoor areas, combined with larviciding of breeding water to cut mosquito numbers fast.
How it works →
Cold Fogging & Larviciding
A non-heated fog for enclosed indoor spaces, with no high temperatures, plus larviciding where mosquitoes breed.
