Doc bolted right for me, as Bobby ran for cover and made me wonder if I should do the same thing. He'd never been aggressive before, but...

I've done my best to avoid the use of dung-beetle killing wormers, but it just doesn't seem to do the trick. They're around, but not in enough numbers to bury many cowpies. Last year I blamed it on the arrival of Doc and Bruce (our draft horses), who had undoubtedly been wormed. This year, Bobby (our driving horse) and Shasta (our newest cow) could be to blame. Maybe the beetles will take over next year, but I'm not holding my breath.
We've got some organic fly spray, which is just a bunch of essential oils (cedar, cinnamon, thyme, etc) blended with mineral oil. Doc knows what it's for, and lets me spray him down with it. Bruce, on the other hand, runs away from me like a two-thousand pound sissy when he sees the sprayer. The cows run away from the sprayer as well. It ain't cheap, but it does seem to work for the animals who hold still long enough to let me douse them. The conventional sprays all use permethrin/pyrethrin, which are actually quite dangerous neurotoxins, so I've been avoiding them.
Let's all hope for a nice early killing frost!
