Terminator Pest Control, strongly recommends all clients to commit to a yearly spray program. The main pest nuisance problem we all face in New Zealand is flies, not only are they annoying, but they also leave unsightly fly dirt on your ceilings, and contaminate you household food. They bring disease and virus into your home, so starting around September, its time to book your treatment. A Yearly full mist spray of the interior, and full knapsack spray of the exterior walls, will not only keep the flies under control, but also the myriad of other flying and crawling pest insects.
