Good thread, some very interesting stuff shown on here.
I have had no bugs from horn/antler pick ups at home or in Africa other than maggots that need cleaning off. But I did buy some wood carvings in Zim at roadside venders, placed in luggage and brought home. Imagine my surprise when a month later I checked them on shelf and found small holes where some bugs/worms had bored their way out and luckily for me died on shelf. Immediately bagged and sprayed. Still bug free today years later, but lesson learned for all subsequent purchases.
When in Military all our foreign local purchases were bagged, tagged and sprayed before ever entering ship, some wild things dead in bottom of bags.
I am always on the lookout for non hunted "trophies" for the memory room. Have some huge paper wasp nests, yes some lava turn to wasps and venture out when nests are hung in warm room over winter. Same for some insect that makes its home in there and makes little pieces of them along with some sort of "dirt" fall out. Now they all get the semi annual spray with Mount Medix products.
Here in BC Gov has stopped us picking up "finds" at least the legal way. Report and request permits but not always are they given out.
