So I am living my dream...moved to the country about 9 months ago. My neighbors are goats and cows (good neighbors to have) and with them comes a huge fly problem. We are talking about hundreds if not thousands of flies around my house. Does anyone have a solution for controlling these annoying flies without taking down the beneficial insects?
See if you can figure it out. Blackflies and horse flies are both very annoying, but their habits and thus methods of controlling them are quite different. If you can get dead ones to examine, if you can notice details of their habits, that will help.
