Yes, I understand as my sister had a fire started in hers when she nuked it too much. That's why I stated to go in 15 second intervals afterwards. I find 60 seconds works most times for me. If I just hang them up upside down, they're fairly dry within a day or two. Have some in my basement bathroom and garage. No spiders in sight now. Hate those little spiders. They seem to take over if you're not careful and I'm trying not to have to use insecticides whenever possible as I have 2 kitties indoors and I don't want to expose them as they are always curious and into things.
