Late spring and summer are prime months for spiders to breed and build webs around homes and sheds. While most native species are harmless, some introduced spiders can pose health risks or become unwelcome housemates.
New Zealand’s most concerning spiders include the white-tailed spider. These species thrive in warm, sheltered environments—under eaves, in garages, and around outdoor furniture. Unlike native orb-weavers, they actively hunt prey, which makes them harder to spot until they move indoors.
The ideal time to carry out spider control is late spring, before egg sacs hatch. A surface treatment across eaves, window frames, and outdoor structures targets both adult spiders and their nesting sites. Interior treatments can be used around ceilings, corners, and baseboards to prevent migration indoors as temperatures rise.
Regular cleaning, removing webs, and sealing gaps help reduce harbourage areas. Follow-up treatments through summer keep populations low, especially in coastal regions where humidity increases insect activity.
By acting early, you’ll keep your home safer and more comfortable while reducing encounters with unwanted eight-legged visitors.
