Well, those I know in the deep south are saying their NN's aren't bothered much by mosquitos. I'm getting suggestions of a bug zapper with mosquito lure, eucalyptus leaves in the coop, some product called Tal-Star, and to be sure to vaccinate your birds for fowl pox if you're having bad mosquito problems. Hope that helps. We are having a more mild and somewhat damp winter than usual around here, so we may have more mosquitos next summer than usual. Will have to see. I put eucalyptus leaves in my coop last year in an effort to keep down the flies, as they get bad, and it worked very well.
