CP... horseflies, black flies, and all those things we dealt with back in the day by having a couple of cattle rubs stationed over their favorite paths (one was in the gate area where they came in to feed and get milked). Not sure if they still make them or if they've changed over the years but I'll describe them to you and see if you know what I'm talking about.
They're long, skinny (narrow), cylindrical tanks with a burlap wrap around them and that wrap held against the tank with a rough corrugated type of mesh screen (similar to a corn screen). Also where the screen bolted together there was some heavy canvas strips that hang down like the scrubbing skirts at the local carwash. Two chains at either end of the tank allows you to hang the assembly at the height of the cattle's shoulders, allowing them to pass under and rub. You fill the tank with what stuff that wicks onto the burlap and down the strips that the cows move through and under and that seemed to really help a lot.
I wish could remember what we used in the tank... I seem to remember we might've used diesel fuel in it? Kerosene? Maybe dad used something he bought at MFA. But, whatever we used, it did a damn decent job of keeping the problem curtailed to minimum issue. Hope that helps.
This is what I use now, I've also done the dust bags and the cows get run through the chute every 4-6 weeks and I apply a pour-on insecticide. In the oilers, we mix diesel fuel with an insecticide and rotate products every month to prevent the flies from developing a tolerance. https://easywaycattlecarellc.com/
I'm trying to figure out how to keep the darn things from chewing up my neck, ears and arms. I walked out of the house this morning to grab something out of my truck without applying any bug stuff and I counted over 30 bites in about 4 minutes and they follow you inside and keep biting. I'm thinking I'm somewhat allergic to the stupid things because they are so tiny but the welts from their bites are bigger than a bee sting. It may have been a combination of the black fly bites and the heat but I fenced yesterday and normally when I start, I'll go until dark but I quit after 12 hours because I felt like shit, there was still 2.5 hours of daylight when I quit but I couldn't do it anymore. Either that or I'm getting old.
They target the back of the ear, neck, insides of your elbows, wrists and they get inside of your shirt around the waistline and neckline. The swarm was so thick in the pasture yesterday I think I swallowed and inhaled about a hundred of the stupid things.
