Like vampires, mosquitoes survive by drinking their victims' blood and starring in popular film franchises for teenagers. Banish these sucking scourges with today’s Groupon: for $45, you get a barrier-spray mosquito treatment for up to one acre of land from The Mosquito Authority (an $89 value).

The Mosquito Authority's local owners, Doug Cutting and Matt Copeland, protect backyard hangouts from pesky skin nibblers with EPA-approved pest-control solutions. First, The Mosquito Authority applies an all-natural, chemical-free barrier-spray treatment to decrease the mosquito population surrounding clients' home or land-locked houseboats. 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, with results lasting for up to 21 days. The solution used to repel buzzy biters contains a safe, active ingredient commonly found in lice shampoo. The solution repels only irksome insects rather than beneficial bugs such as honeybees, butterflies, and spider-men.
