Take The Sting Out of Wasp Control

Whether the type of wasps you have are predatory or parasitic, they are a significant nuisance and liability. And though they can function as pollinators of plants and flowers, as well as assist in the management of other pests by killing and consuming them, wasps should not be in any commercial environment.

Wasp nests can vary a lot. In order to build their nests from wood fibers, they look for locations (enclosed or open) that are left undisturbed. Typical sites include bushes / trees, under eaves, under exterior fixtures, and around door or window frames. On the other hand, yellow jackets nest in the ground.

Anywhere they nest, our technicians will find the wasps and put preventative wasp control measures in place for peace of mind.
