I have had very good luck controlling flies with this rub. The strips hanging down seemed to take care of the face and eye flies on Herefords. With the 2 month old calves you may have to hang it lower. Just pour a mix of diesel fuel and insecticide on the rub every couple weeks, it wicks down to the "flyps" and gets their eyes every time they go thru.

I think the key to success is placement. I had it in front of a water access lane so they would go thru a couple times a day. Here's a picture from last summer. The hanging strips are the key for eye problems. I'll list the website in the US.

There may be something like this made in South Africa or Paul White may ship to you. Good luck.
