Mr. Mister doesn’t just keep your home mosquito free, we work to protect people from mosquitoes and home and around the globe. Mosquitoes are one of the deadliest animals on the planet because they spread malaria. Fortunately, some simple steps can help protect children and adults. One of the best ways to prevent the spread of malaria is to use mosquito nets, especially at night. So with every purchase, Mr. Mister makes a donation to Nothing But Nets, a nonprofit that fights malaria across the world.
