RE: Do you cut up your deer the same day as harvesting it?
City Slicker, if it's warm enough to worry about flies and such on the carcass then it's too warm to hang it.
You can use the cheese cloth type bags to help protect the meat. I've also heard of folks rubbing pepper on the meat to keep bugs off when it's warm.
In warm weather, skin it and get it in the fridge or cooler asap.
I've gotten meatfrom agame processor that had fly eggs in it. EWWWWWW!!!! [:'(]
