Killing the bugs on the mounts is not killing the entire population---you need to remove the "source" of the infestation here and kill all the larvae that haven't hatched yet.
Now for some questions for the OP here and please be honest. Do you have any "home taxidermy" items in your collection? These could be self done antler mounts, turkey tails, pheasant skins, salted skins (of anything) or even deer antlers cut off with the skull cap skin still attached.
Do you have dry dog or cat food stored indoors? How about bird seed?
If the OP answers "yes" to any of these questions he will have the source of his infestation. Dermestids make their way into almost every home on pet and human feet or in bags of dog food or bird seed. Once in the home they are going to seek out the easiest, quickest food source in that home. It is almost ALWAYS "home taxidermy" items like I just mentioned. Only after the easy stuff is eaten will dermestids attack properly done mounts. Properly tanned skins, boraxed birds and freeze dried turkey heads are not very attractive to dermestids but they will certainly eat them if that is all there is.
Immendiately get rid of ALL home taxidermy items. Don't just put them in the garage---get rid of them. Store dog food and bird seed outside in a shed or box away from the house.
Finally, call a good, reputable exterminator. You need to remove ALL of the bugs---not just the ones on your mounts. They are living in your carpets, your curtains and your clothes. The only way to permanently get rid of them is to hire an exterminator.
If an exterminator is not an option for financial or other reasons you must, at the VERY LEAST, buy some bug bombs and follow the instructions exactly. You will need one "bomb" for every room in your house---larger rooms need two. You will need to do at least TWO "bombings" about 4 to 6 weeks apart to be completely rid of the infestation. Expensive? You bet! But, then again, so are the mounts you're currently feeding your resident bug population!
