Freeze, put in microwave, refreeze. If they are bad, as it seems it may be...I would let it thaw outside for two-four days, then refreeze. Then I would wash them in Dawn dishwashing soap, and let them dry very well. Then I would make very sure you put them in zip lock bags. Put the bags in a moth balled container such as a plastic tube with a locking lid. Keep this away from your other materials for a few weeks. If you see no problems, you are free and clear. I know lots of people use moth balls, and a piece of flea collar cut off, that is placed in a container. Cedar is another repellent, but I would trust moth balls more.
As long as I get a bite, I don't want to leave!
