Definition - What does Bee Spray mean?
Bee spray acts as a repellent, keeping wasps and bees away. It usually contains different chemicals, depending on the type of insects it protects against. A common chemical found in many repellents is DEET (N,N-diethyl-m-toluamide), which was developed and tested in the 1940s and 1950s by the U.S. Army for use in jungle warfare. DEET is extremely efficient at repelling mosquitoes, ticks, fleas, chiggers and blood-feeding flies such as black flies and deer flies.
Bee sprays come in the form of aerosols and pump sprays, and can keep insects away for hours after application. They can be applied directly to working surfaces or premises as well as workers. Liquid sprays of carbaryl (Sevin), chlorpyrifos (Dursban), or a synthetic pyrethroid (e.g., permethrin or cyfluthrin) are used as a preventive to wood surfaces which are attracting bees. DeltaDust (deltamethrin) or various liquid or aerosol pyrethroids are effective against bumble bees.
Safeopedia explains Bee Spray
Bee sprays and fly repellents can be made to be natural, biodegradable, and environmentally safe. They act as a natural barrier for bees and flies as well as for many other flying insects like wasps, hornets and yellow jackets. Potency of bee sprays varies depending on the ingredients used.
Bee sprays create a non-toxic virtual barrier around people and the place they work or live, deterring bees and other social stinging insects. Most bee repellents rely on a natural formula that is pesticide & insecticide-free as well as environmentally friendly. Controlling bees without harming them is of the utmost importance, which is why the University of Missouri lists the following compounds in bee sprays for the chemical control of bees as safe : "Pyrethroid: Allethrin, Bifenthrin, Cyfluthrin, Cypermethrin, Deltamethrin, Esfenvalerate,Lambda-cyhalothrin, Permethrin, Sumithrin, Tetramethrin and Tralomethrin Botanical: Phenethyl propionate and Pyrethrum"
