I`ve noticed quite a few properties that have wasps flying around the cracks and crevasses of steps and foundations lately while showing to buyers.Wouldn`t you know, that when i arrived home the little buggers were flying into a space between my brick.
First thing to do in order to get rid of them is identify the culprits. Are they wasps, jellow jackets or bees? By late summer the numbers of yellow jackets will have increased tremendously and they will be more likely to sting anyone coming near the nest. The openings of their nests are quite visible.The most challenging nests to control are those that are concealed in voids behind walls or in attics. Often, the only evidence of the nest is wasps flying back and forth through a crack or hole in the home.
Old nests are not reused by wasps. Wasp nests found during winter or early spring are old nests from the previous summer. There are no live wasps in the nest; they have already left or died inside it. The nest can be safely removed and disposed of if desired.
If you decide to wipe out these little pests, you could contact a pest control company or do it yourself. Locate the opening or openings and spray a wasp/hornet insecticide into the cavity opening. Evening is the best time because the majority of the insects are in the nest and not flying. Wearing gloves, a protective veil and clothing is advised. Follow the instructions and precautions on the label. It may take more than one application to completely destroy the colony.
If the nest is located in your home, do not simply close up the opening because these insects may find a way into the living area of your home. Wasps or yellow jackets that come into the home are usually not aggressive and often will be found at the windows looking for a way out.
Afterwards use a spray foam insulator to keep the whole closed for good.
