Detering wasps can be as easy as making your property less wasp-friendly. Trim trees and bushes near your home, as wasps like to build their nests in these areas. Remove wasp food sources by sealing garbage cans and keeping food covered outdoors. Wasps are attracted to sweet smells, so avoid using perfumes or scented products outdoors. If wasps are still a problem, wasp-repelling products are available at hardware stores. There are many DIY methods to control wasps, but the best way to deter wasps from your property is with the help of a professional pest control company.
