An outdoor perimeter spray creates a treated band around the outside of the house. It is aimed at the places cockroaches and other crawling insects use to get in: door frames, weep holes, pipe entries, window frames, garage doors and the base of the walls. For many homes in North Lakes, it is the part of the treatment that keeps large cockroaches from coming inside in the first place.
The crew we book walks around the house before spraying. They look at garden beds, fresh mulch, downpipes, stormwater grates and any spots where plants press against the walls. Newer estates often have garden beds right up against the brickwork, which gives cockroaches cover and a direct line to the weep holes. The crew may suggest pulling mulch back a little to leave a clear strip.
A perimeter spray usually covers:
- External walls up to about a metre high
- Weep holes, vents and pipe entries
- Door frames, sliding door tracks and the garage door
- Garden edges, paths and fences where needed
- Eaves and window frames 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 the day before rather than straight after, bring in washing and move outdoor toys. A perimeter spray also helps with ants and spiders, so if those are a problem at your place in North Lakes, mention it when you call and we will add them to the upfront price. Try to keep sprinklers off the treated walls for a couple of days. Call 07 3543 7767 to book an outdoor perimeter spray with a local crew.
