Where's my disintegrator/integrator?

In the seven years we've lived in this house, I've seen maybe two houseflies the whole time. We just don't have a fly problem.

Day before yesterday, we suddenly had dozens. Maybe a hundred. Eeeek!

The boyfiend vacuumed up a lot of them and released them into the wild, but they were still going strong today.

So we spent a good chunk of the day cleaning the kitchen, putting away food and eating utensils, and preparing to nuke the things with a flying-insect mist tomorrow while I'm at work.

No, I don't like using poisons. The alternatives were just too gross for me to contemplate. Please don't judge.

Bleah. The shame and revulsion and EEK! are so strong.
