There are bettles/wevils that will eat horn. I had a blackpowder powder horn made from cow horn. I was hanging out in my shed. I noticed the other day it had trails or grooves in the horn that look as if some insect had eaten it. In some places they had penetrated the horn itself.
"Marv Gaston, owner of Taxidermy Unlimited, said beetles and moths feed on the protein matter of hair, fur, feathers, skin, antlers, horns, hooves and claws. One reason the insects are showing up on trophies more frequently is that tanneries are now prohibited from using arsenic or other residual chemicals in the tanning process.
Skins are now soaked in a liquid and absorb an insect repellent which can sometimes keep bugs away for years. However, a trophy should be inspected annually. Clinton said birds, especially turkeys, are susceptible to infestation. Larvae will devour leathers and if the damage is not recognized early, the trophy is usually irreparable.
A sure-fire way to kill insects and larvae is to put the mount in a freezer. However, all mounts need to be moved into cold storage at the same time to ensure that all of the trophy-eating critters are wiped out."
If you have any such products check them regularly for signs of damage. When I read this I added bug protection to the safe that holds my guns and knives with stag grips.
In my neck of the woods deer shed in January, rodents eat the deer antler sheds, usually within 6 to 8 months, for the calcium they contain. We rarely find intact antlers during the bow season that starts in September. If we are going to get them we have to start looking in Febuary or March.
But no, I have never heard of such a thing.
