Bees - Hornets - Wasps

Paper Wasps

Paper wasps, hornets and yellowjackets construct nests of a paper-like material which is a mixture of finely chewed wood fragments and salivary secretions of the wasps. Paper wasps typically build their umbrella-shaped nests under eaves and ledges. These wasps are not as aggressive as yellowjackets or hornets and don’t nest in such large numbers. 

Hornets and Yellowjackets

Hornets and yellowjackets are far more difficult and dangerous to control than paper wasps. The nests resemble a large, inverted tear-drop shaped ball which typically is attached to a tree, bush or side of a building. Hornet nests may contain thousands of wasps which are extremely aggressive when disturbed. The nests are often located out of reach and removal is best accomplished by a professional pest control firm.

A full wasp suit sealed at the wrists, ankles and collar is recommended when disposing of a hornet nest. Treatment can be accomplished by applying a wasp freeze-type, aerosol insecticide or dust formulation directly into the nest opening. Hornet nests have a single opening, usually toward the bottom, where the wasps enter and exit. It is essential that the paper envelope of the nest not be broken open during treatment or the irritated wasps will scatter in all directions, causing even greater problems.  Following treatment, wait at least a day
