Thermacell makes devices that work like diffusers, using heat to vaporize a small amount of insecticide into the air to create a bug-free zone. The active chemical is either metofluthrin or allethrin, which in numerous studies have proved to be effective spatial repellents for mosquitoes lightweight, ultra-portable Thermacell Backpacker mosquito repeller and it actually works. Here's why we love it.

I received this item for free from Thermacell in exchange for my honest review. I received this product and put it to work at my backyard barbecue for my neighbors. This product kept the mosquitoes at bay and everyone was very impressed. I think I inspired everyone to get one for themselves.

Bought this last week and I can't believe I can now sit on my porch and NOT be the buffet for the mosquitoes!! I LOVE this little machine. We've tried different things over the years but they only seemed to attract flies and moths. :/ I paid full price but it was well worth it.

I moved to New Mexico from Massachusetts, thinking I was saying goodbye forever to mosquitos. That lasted about 17 years until our climate shifted just enough to allow the tiniest, striped devils to take root in the desert. The past two years have been unbearable! Thankfully, a friend told me about Thermacell, and it's been a life-changer. I set it out and in no time, I'm back to having coffee on the porch, weeding my garden undisturbed, or having friends over on the patio at sunset. I will absolutely be buying additional units for each area and stocking up on refills along with telling everyone about this product. Thank you for giving me my outdoor life back!

I was amazed at how fast this repeller works. I live in Florida and some days if I leave the porch light on at night, hundreds of mosquitos invade my porch. I put the repeller outside and in less than 10 minutes all the mosquitoes were gone and I was able to take my dog outside. Great product!

This sample i receive is what i need around the house. Dont take long to charge and when turning on and has a jingle one the high side to let you know it on and turning it off it jingle on a lower sound letting you know it turning off. It doesnt put off any smells and it keeps the pest away. Now i do notice if the some wind while using the device it doesnt work as well but on a calm day it works great.

I work at a home improvement store and every single customer states that this works 100%

Have to give it 2 stars fir now because the “included 12 hour refill” was NOT included

Love using this product when sitting out on the patio - keeps the mosquitoes at bay.

I like these products. They do work as intended. Work great outside sitting around, hiking, walking. Great at a game too at night. I just don’t like the refills are expensive.
