I'm glad that you mentioned alcohol in the refrigerator. That sounds perfect. I read alcolol can be bought in a stronger % than rubbing alcohol. Will research that. I wonder if adding water will lessen it's effectiveness? Just an idea to stretch it, since I think I need to treat all the house and contents, and attic.

Do you know if alcohol will kill the eggs in the ground?? I threw pails of bleach water out in the place the dogs do their business today. Sad to see earthworms rise to the surface and die immediately. This whole thing is sad.

I'd like to get an air purifier as well. Thanks for the mention. Not sure what the infra red means, it's more expensive.
