The Mosquito Authority protects backyard hangouts from pesky skin nibblers with EPA-approved pest-control solutions. First, The Mosquito Authority's process utilizes an all-natural, chemical-free treatment that decreases the mosquito population surrounding your home or land-locked houseboat and guaranteeing 21 mosquito-free days, or The Mosquito Authority returns to retreat the area. Then an entomological hide-and-seek specialist locates the areas where mosquitoes are hunkering down between hemoglobin snacks and sprays a mild insecticide designed to send them on a much-needed sabbatical. The solution used to repel buzzy biters contains a safe active ingredient commonly found in lice shampoo, and eradicates only irksome insects rather than beneficial bugs such as honeybees, butterflies, and spidermen.
