When you need data to support your claims for outdoor mosquito repellents such as candles, torches, coils, heated pads, and similar products, the options are certainly limited. Traditionally EPA has required open field tests but such methods rarely provided suitable results. Over the past few years, EPA has been allowing huge outdoor cage tests. We have 3 massive cages with a method that has been used for several recent EPA registrations. This method is ideal for most any type of area-wide repellent device. Up to 3 species of mosquitoes are released at the ideal rates per species to create a suitable pressure. The entire test is configured to wind directions for the optimum coverage area of each product.
