I just came across this in a catalog, in case anyone is interested. Might be worth a try if you have an infestation in your yard. I'm not sure how it works on mosquitoes, maybe the larval stage. We have tadpoles, frogs, and swallows that keep the mosquito numbers down.
If any of you try it, let us know how it works.
They also have a wrist band to repel insects.
I hope it's helpful to some of you. They do have a guarantee.
