Nothing adds insult to injury quite like a mosquito bite on a hot summer day. And if you’ve tried the candles, sprays, lights and everything else, you may think the fight against bugs is hopeless. Luckily, we spotted an easy and odorless way to repel those mosquitoes with this rechargeable mosquito repeller by Thermacell.

“My husband is allergic to mosquitoes and usually gets eaten alive in the summer months,” one user said. “While using this little device, he didn’t get a single bite. Worth the money.”

This Thermacell repeller set comes with a repelling device, a 36-hour oil refill and a USB charging cable to keep its power going for up to a claimed 6.5 hours. Customers say it’s been an essential tool to keep on the patio or backyard, and even when camping.

“It actually works!” says Don G. “We’ve tested it by sitting out on our deck without it and getting bit — then placing it on our deck and waiting 15 minutes and then sitting bug-free. We read all of the reviews and found that those who rated it high were right; it works.”

Another reviewer reported their success: “I went camping in the woods and allowed the mosquitos to start coming around first, but once I turned on the Thermacell, they never came near me and my family. I tested this over 2 days.”
