Summit 20 Count Slow Release Mosquito Dunks

I've been purchasing these ever since I heard about them about five years ago and I've been using them ever since. They're great for keeping the mosquito population down, not eliminated, but controlled. I put them in my birdbaths, wildlife water bowls and fountains. They don't kill the mosquitoes or larvae, but keep the larvae from hatching into mosquitoes. They work for me. I notice the large difference in mosquitoes when I don't use these. That is when I go buy more. With this big 20pack, I won't run out. The price is great too. I live down in the Deep South, the Delta and mosquitoes are a nuisance. With all the diseases they carry, I don't like the idea of having any of them multiply. Hate mosquitoes? Try this and you won't be disappointed.
