There are several different type of wasps, and the one that typically attacks humans are known as yellow jackets. They nest in the ground or in the wall void of a home and they are very aggressive. They need to be taken care of right away. Wasps are meat eaters, which is why we see them when we’re picnicking, but we also see them on plants at certain times of the year. Usually they are just looking for insects to consume, but if they are in a nest, they are very aggressive and do what they can to protect that nest.
ATCO’s process for wasp control is to hook up a vacuum to the entry/exit points and remove them rather than using an insecticide. Once we’ve captured most of them in a vacuum we can use an eco-friendly dust inside the nest or simple seal the hole, bypassing any insecticide use and trapping the remaing pests inside to die off naturally.
