A man at the party sprayed the lawn and deck floor with Listerine, and the little demons disappeared.
When next outdoors at a picnic I took a 4-ounce spray bottle I had filled with Listerine and sprayed it around my seat when I saw mosquitoes. Voila! That worked too
Now during the summer, I don't leave home without it..
COMMENTS: I tried this on my deck and around all of my doors.
