So I bought the DE for fleas in the house and spent a weekend painstakingly applying it to the carpets.
Apparently Sierra doesn't think I did it right.
I came home today to find a path of DE powder trailed around the house and the inside of the house was a big dust cloud. Almost an entire 5 lb bag! It was EVERYWHERE. Oh man, Jeff was NOT HAPPY AT ALL. We spent a half hour trying to figure out how to clean it up without stirring up more dust or destroying the vacuum. Eventually, my MIL sacrificed one of her old vacuums, which we ruined, but we got it cleaned up.
It never ceases to amaze me the trouble this sweet dog can get herself into.
