Spotting a wasp nest
A wasp nest on the property is another telltale sign of an active wasp infestation. Wasps build their nest in hidden, sheltered areas for protection from the elements. Some common home areas where wasps are likely to build a nest include garages, attics, chimneys, awnings, bird boxes, sheds, fence corners, bushes, tree trunks, and beneath the roof. Wasps have distinctive nests, often light in color with a grayish tone, and look paper-like. Wasp nests can be built from mud particles or chewed wood, depending on the species. However, only attempt to remove or destroy the wasp nest with professional assistance.
When it comes time to remove these insects from near a structure or heavily trafficked area, you may want to consider hiring a professional pest control company. Wasps can be managed by most homeowners with a broom (if the nest is small and/or relatively inactive) or aerosol insecticides specifically formulated for wasp control. Yellowjackets and hornets are trickier to deal with and should be approached very cautiously. Spraying aerosols into a yellowjacket entrance hole is dangerous and may not be very effective as some colonies can be up to a foot wide and contain over 2,000 yellowjackets. Any attempts to control wasps, yellowjackets, and hornets should be done in the evening when they are less active and with appropriate clothing that covers the skin.
