Thermacell Perimeter mosquito control devices. Two mosquito control devices create a mosquito-free zone of roughly 40 m2 within 10–15 minutes. Thermacell Perimeter mosquito control devices can be staked into the ground or mounted to exterior structures.
A mosquito control mat containing prallethrin is inserted into the device. The gas heats up the mat, which then releases an active substance that forms a roughly 20 m2 zone of protection around the device. No need for topical lotions or sprays: Thermacell protects everyone within the zone.
Perimeter devices are perfect for summer parties, evening gatherings and outdoor games. Several devices can be used simultaneously to cover a larger area.
The package includes two Thermacell Perimeter mosquito control devices, two poles and two surface mounts, including fasteners, as well as two gas cartridges and six mosquito control mats for roughly 12 hours of use.
Use Thermacell safely. Read the label and product information carefully and familiarize yourself with the instructions for use. Use and store out of reach of children and pets. Use at a distance from flowering plants. For outdoor use in yard areas only.
The empty Thermacell gas cartridge and mosquito control mat are disposed of as mixed waste/combustible waste in accordance with local guidelines. If the gas cartridges or mats have not been used completely, they should be disposed of as hazardous waste.
Color: black.
