these work for me.
I have a corner lot with drainage ditches which turn into little swamps all summer. I'm not outdoors much but the damn mosquitoes getting into the house used to drive me nuts all summer. I picked some of these up at the hardware store to try and they worked.. just plopped in the two standing water areas ( the drainage ditch and the area in my backyard my sump pumps into) and I'm mosquitoes free for a couple months. I was glad to find this bulk purchase option available.
