Wednesday's "Clean Me" is a small but important victory. For the first time in more than two weeks, not one single fly emerged from my kitchen drain.
If you ever find yourself in this predicament, I recommend Earthworm. This remedy was time consuming -- overnight every night for six nights -- but it was safe for both my plumbing and my fur family, and that was important to me.
I laid in a couple extra bottles, plus baking soda and vinegar, and hopefully with regular maintenance this will never happen again.
