 So mosquitoes, the first part of their life cycle, the larvae, they actually live in the water. So dump any that you can find. Meanwhile, here's something to try at the cookout itself. I'll just turn this fan on. Fans work great too. A lot of these insects like flies and mosquitoes, they're not great flyers. So if you get like a standing fan that you can put out, you're not only keeping yourself cool, but you're also going to deter these flying insects too.
