The roof void is one of the main shelters for American cockroaches. It is warm, dark and seldom disturbed, and in North Lakes homes it often sits over plasterboard ceilings with downlights, exhaust fans and air-conditioning ducts that leave small gaps into the rooms below. If you see large cockroaches coming from light fittings, vents or above the cupboards, the roof is a likely source.
The crew we book reaches the roof space through the manhole and checks for droppings, egg cases and live cockroaches, mostly above the kitchen, bathrooms and laundry. They then apply an insect dust along the wall plates, around fittings and into the corners where cockroaches harbour. Dust settles into small gaps and stays in place in dry spaces, which is why it suits roof voids well.
A roof void treatment usually covers:
- A check through the manhole for signs of activity
- Dust applied along wall plates and around fittings
- Attention above wet areas and the kitchen
- Treatment of wall cavities where there is access
- Advice on sealing gaps around downlights and vents
Roof void work is usually one part of a wider plan. It is often paired with an outdoor perimeter spray and some gel bait inside, so cockroaches are dealt with in the roof, at the walls and in the rooms where they show up. Two-storey homes and those with low-pitched roofs can take a little longer to reach. For the visit, make sure the manhole is easy to get to, and clear any stored items from underneath it.
