I have 20 deer heads, 5 turkeys, 11 ducks, 1 bobcat, 2 foxes, 2 squirrels, 1 coyote, 1 badger, 1 groundhog, and a sharptail grouse all in my condo. Starting about 3 years ago, I noticed certain mounts seemed to be losing their fur, or feathers. Upon closer inspection, I noticed tiny cocoon-like sacs on these mounts. I cleaned them off, only to find they had returned a few days later. I had an exterminator come out and examine them - took pics and samples. After these were examined by an entomologist, they were determined to be carpet beetles. I brushed all mounts with a wire brush, sprayed with the poison recommended, but they returned. I paid 1,000 to have my place heated to 150 degrees for 4 hours - thought it worked but I just found more damage after 9 months of no activity. I swear I keep my place clean! If I don't do something, all of m mounts are going to be destroyed. But I don't know what else to do. Any thoughts?
