As summer gets hotter, wetter, and all around muggier, mosquitoes are out in full force. So, I consider the best $30 purchase for my patio and deck areas to be the Prime Day deal on Thermacell mosquito repellent. Marked down 25 percent for Amazon’s sale, this device diffuses a pyrethroid called metofluthrin into the surrounding air to deter would-be pests for up to 9 hours at a time on a full charge and new cartridge (also on sale). Instead of dowsing myself and my guests in a sticky DEET-based repellent, this gadget the size of a Bluetooth speaker can create an odorless but effective forcefield up to 20 feet across.

Our writer Tony Carrick tested this specific device out on a three-day camping trip in a wooded area and found similarly impressive results: “Within about 5 minutes, I noticed a rapid decline in mosquito activity. After 15 minutes, mosquitoes had fled the immediate area,” he shares. “Its ability to eliminate mosquito activity within a 20-foot zone makes it the ideal way to protect your deck or patio. As I discovered, it’s also a great companion to bring along on camping trips.”
