It’s officially Labor Day weekend. Whether you’re hosting a backyard barbeque with family or going out on the lake with friends, you might notice some uninvited guests. We aren’t talking about nosy neighbors, we mean mosquitoes and other super annoying insects. Especially the ones that bite.

While you’re probably already using bug spray, sometimes that’s not enough to keep their buzzing butts away. Add this mosquito repellent electronic watch band to your insect armory. It’s now even on sale for only $16.99, normally $39.95.

While bug spray works by emitting a smell that bugs can’t stand, this watch band does the same thing, just with ultrasonic waves. The manufacturer claims that it can keep 70% of bugs away from you, so it’s still a good idea to wear bug spray to cover all of your bases.

Unlike bug spray, this silicone watch band is completely non-toxic and safe to wear indoors and out. An adjustable band allows for a snug fit that works for both adults and kids. It charges up quickly and has a strong battery that can last up to 130 hours — that’s longer than Labor Day weekend!
