I haven’t followed this thread very closely, so please forgive me if someone already sent in this idea. But my mother in law just sent me an email that said you could keep mosquitoes away from an area by simply spritzing Listerine around on the ground. Like say, if you were going to have dinner on your patio, you could just spritz the Listerine on the patio floor and it should keep the mosquitoes away.
I have never tried this, so I can’t vouch for it, but it seems like it’s worth a try. If you can put the stuff in your mouth, it should be safe enough to spray around pets and kids.
