Jay –
I try and concentrate on eliminating where they breed near the house and barns. In the barns I use sticky traps that hang down (come in a cylinder, you peel and unfurl it in a long strip and hang from the string attached to it). They are attracted to it and stick. I use lavender and cloves in bowls around the house as a repellant.
Here’s all you need to know about handling the problem! HTH!
