Subject: weird yellow fluffy substance found
When I was recently taking down my mason bee hotels and houses, I found a yellow fluffy substance in several of the boxes. It seems almost like wall insulation. One seemed to have cocoons in it.
Do you know what this is? Should I just clean the cacoons and boxes as usual with Chlorox? Do I just throw this stuff away? leave it in the recycle?
