A great tip from Horse
In The South.com: So you don’t like those pesky mosquitoes, especially now that they have the potential to carry the West Nile Virus? Here’s a tip that was given at a recent gardening forum. Put some water in a white dinner plate and add a couple drops of Lemon Fresh Joy dish detergent. Set the dish on your porch, patio, or other outdoor area. Not sure what attracts them, the lemon smell, the white plate color, or what, but mosquitoes flock to it, and drop dead shortly after drinking the Lemon Fresh Joy/water mixture, and usually within about 10 feet of the plate. Check this out—it works just super! May seem trivial, but it may help control mosquitoes around your home, especially where the West Nile virus is reaching epidemic proportions in mosquitoes, birds, and humans.
Think there is something we could use to keep the mosquitos from biting horses or people, for that matter?
