The roof space above the ceiling is dark, dry and seldom disturbed, which makes it a perfect spider shelter. In Brisbane, older homes with tin roofs, gable vents and gaps along the eaves give huntsman spiders and black house spiders plenty of ways in. From the roof they find their way down through downlight gaps, cornices and the manhole into bedrooms and living areas.
Roof space spider treatment uses a fine insecticide dust spread through the ceiling space with a hand puffer or powered blower. The dust settles over beams, rafters, insulation and ledges, and spiders moving through it are affected over the next few days. Because it stays dry and undisturbed up there, dust keeps working far longer than a spray would in an open, sunny spot.
- Access through the manhole or ceiling hatch
- Dusting along rafters, beams and wall plates
- Extra attention near gable vents and eave gaps
- Look for signs of heavy spider activity or egg sacs
- Tips on sealing gaps around downlights and vents
Before the visit, clear the floor under the manhole so the crew can set up a ladder, and move anything stored near the hatch. The crew needs a manhole big enough to fit through and enough headroom to move about. If your roof space is very low or tricky to reach, tell us on the phone so we can pass it on to the crew.
Roof space work is often paired with a perimeter spray to treat both where spiders enter and where they shelter. We give you upfront pricing on the phone before booking. To book roof space spider treatment in Brisbane, call 07 3543 7772 and we will line up a nearby crew.
