An outdoor perimeter spray puts a treated band around the outside of your home. It targets the places where cockroaches and other crawling insects come in, such as door frames, window sills, weep holes, pipe entries and the base of external walls. For many homes in Chermside, it is the outside half of a good cockroach plan. It pairs well with gel bait inside, so cockroaches meet treatment on both sides of the wall.
The crew we book walks the outside of the house before spraying. They look at garden beds, mulch, leaf litter, downpipes and any sub-floor areas. They also check where the gardens touch the walls, since thick plants and mulch against brick or timber give cockroaches easy cover right beside the house. Where plants press against the house, the crew may suggest trimming them back to open up a gap.
A perimeter spray usually covers:
- External walls up to about a metre from the ground
- Door frames, sliding door tracks and window sills
- Weep holes, vents and pipe entries
- Garden edges, paths and the base of fences where needed
- Eaves where spiders build webs
Keep children and pets off the sprayed areas until they are dry, which usually takes a few hours. Water the garden before the visit rather than straight after, and bring in washing and toys. Try to keep sprinklers off the treated walls for a day or two. A perimeter spray also helps with ants and spiders, so if those are a problem at your place in Chermside, mention it when you call and we will include them in the price. Many people pair this spray with roof void treatment for large cockroaches. Call 07 3543 7772 to book an outdoor perimeter spray with a local crew.
