HOW CRAWLING INSECT SURFACE SPRAYS WORK?

Crawling insect surface sprays work on the principle that after spraying an area, a thin layer of insecticide remains as a residue on the surface of the material. When an insect walks across this surface, they pick up the insecticide on their legs and body. The insecticide either enters their body directly or as a result of grooming and the insect dies.

The speed of kill depends on the amount of insecticide they pick up and their susceptibility to the insecticide. However, even on a freshly sprayed surface, the insects don’t pick up much insecticide and it will take minutes or even hours for the insect to die. It is therefore quite possible for homeowners to see insects apparently walk across treated surfaces with no apparent effect.

However, assuming the insect has picked up enough insecticide they will eventually die.

Topone Insecticide Spray lasts up to 4 weeks to kill bugs that land on treated surfaces

HOW DO YOU MAXIMISE THE PERFORMANCE OF A CRAWLING INSECT SURFACE SPRAY?

Cover a large enough area – when spraying the external perimeter of the house, it is generally advised to spray 1m up the wall and 1m out from the wall. This provides a significant treated area such that insects walking over this area will pick up a larger dose.

Ensure even coverage – make sure you apply the correct amount of product (as directed by the label) and ensure even coverage (with no gaps)

Shake the product before and during use – if the insecticide is not evenly distributed within the container, you will not get an even dose coming out of the container. Some product types require more shaking than others as the insecticide “settles out” quicker.

Re-apply when necessary – for most homes an indoor and outdoor treatment twice a year is enough to keep the insects at bay. However, for floors inside the home that are washed frequently or for exposed areas outdoors or on aggressive surfaces like concrete, more frequent applications will be necessary to maintain a pest free home.
