Stop being an all-you-can-eat buffet for those intolerable mosquitoes every time you want to enjoy an evening in your backyard. The Personal Mosquito Repeller repels mosquitos up to 322 sq. ft. away and gives you twice the repelling power than others out there on the market. The repeller uses a fan to blow the smell of scented citronella pads and sonic sound to keep mosquitos away. This is a pack of 12 citronella scented pads to use with the Personal Mosquito Repeller.
