Heel fly season

[danl]

Any one know when the end of Heel Fly season is in Southeast MO?

I have a couple of cows I need to reworm and don't know if I waited to late. Although I have not seen a heel fly or saw my cows running around like they were after them, doesn't mean they are not around I guess.

It's been over for better then a month around here. We usually figure around the 1st of September
