The Thermacell MR300 Mosquito Repeller offers a smarter way to enjoy outdoor spaces by creating a protective zone that keeps mosquitoes away before they reach you. Instead of applying sprays or lotions, the device gently heats a repellent mat to release a scent-free vapour that forms an invisible barrier around your seating area.
With coverage of up to 20m², it’s ideal for patios, gardens and campsites, giving you freedom to relax without constant reapplication of traditional repellents.
The MR300 is powered by a compact butane cartridge, meaning there are no cords or batteries required. This makes it highly portable and perfect for outdoor use, whether you’re gardening, fishing or enjoying an evening BBQ.
Each repellent mat lasts up to 4 hours, gradually changing colour to indicate when it needs replacing. The device typically includes enough fuel and mats for around 12 hours of total use, making it ready to go straight out of the box.
Unlike candles or coils, the MR300 operates without smoke, flame or strong odours, offering a more comfortable and discreet solution. It begins working within minutes, creating a reliable zone of protection that allows you to enjoy your outdoor space in peace.
