Anybody know how to kill these little kritters? I sparayed with raid and it seemed to tick them off. The reason I ask is because I had a deer hide from a very large (240 lb.) whitetail that I was going to use for some projects. I had basically made rawhide, but left the hair on to line a quiver and other stuff. I opened up the bag and found a bunch of beetles and a pile of hair. The hide was distroyed. Them I checked another bag that had two grocery bags full of processed sinew in it. They were all in it munching away. Any ideas on how to get rid of them? I know they multiply quick. I would like to alvage as much os the sinew as possible.
