I ordered a couple of packs after seeing someone else talk about them on Instagram. I luckily don’t have a ton of mosquitos around my house but I was camping in the Redwoods a few weeks ago and we were completely swarmed morning and night - the most mosquitos I’ve ever seen. I passed them out to the group and they were a trip saver. After 4 days, the only bite I got was when we were packing the car and I changed out of the shirt I had my sticker on!
