flies

the bulls have had flies on them for the past few days. Yesterday I hosed them down, the flies just hopped back on. So I shampooed them off ... Seemed to work for a bit. Then this morning the flies were back, not quite as bad, but still very bothersome to the boys. So I made a homemade spray of 3 parts water, 1 part vinegar, and a squirt of blue dawn. I hope it works, the boys were mad at me and ran away to the barn...lol. Hoping this homemade concoction works!
