Biting flies like midges and no-see-ums come from muddy ground and some species from water, so for these flies, try to keep areas dry by making sure you have good drainage, and fix any leaking water hoses and water tanks. Biting stable flies develop in decaying moist vegetation like hay chaff, lawn clippings, dead weeds, etc. Be sure to compost grass clippings and weeds from weed eating or spread them thin to dry. Clean out mower decks and grass collection bags each time you mow.
Use Fly Predators to cull your house fly and biting stable fly populations and Bugpellent in the stable to keep any remaining flies that might come over from your neighbors or when guest trailer in at bay!
Happy Summering!!
