HeHe! Love that visualization, MM~~ Fairies in little gas-masks!
I like the reply of the Diatamacious earth, too. I was wondering if there was something like that that could be helpful - it's amazing what some very natural things can do.
I'm also pleased that the manager is fumigating the adjacent apartments, that gives me a much calmer feeling about them not migrating to yours. I'm feeling much more positive about this than I did before, for what it's worth.
Good work - you're doing great!!
