You guys are SOOOOOOOOOOOOOOOO much help! I decided to nuke them. After 20 minutes in the microwave I think I got them all, sounded like popcorn for about 5 minutes. Seriously, I will let the humi sit for a few weeks before refilling. Hog, any wood, any project. The good lord gave us women and wood to mold into things to serve us, thank God trees can't talk!!
