Here's a fun & hopefully helpful idea.

How to Kill those pesky Mosquitoes

Fill a 4-ounce spray bottle with Listerine and spray your yard, seats, doorways, window frames & any nearby standing water then watch the little demons disappear!

OUR FRIEND'S COMMENTS: I tried this on my deck and around all of my doors.
It works - in fact, it killed them instantly. It really doesn't take much, and a big bottle is less than $2 (or maybe your friends will send you a few bottles) and not as expensive to use as the can of Bug-spray.   So, try this, please. It will last a couple of days. Don't spray directly on a wood door (like your front door), but spray around the frame.
