We are being plagued by fruit flies. I dunno if it's the city workers' strike or the cool, wet summer we're having but we are inundated.
So, using the power of the Intertoobz, I researched the topic. Here is a source with lots of things to try, but there is an Ultimate Fruit Fly Killing Machine not included there.
Somewhere else (can't remember and too lazy to look) I found a variant of No. 8, The Wine Trap. Then I improved it.
Get a jar with a lid. (I'm using Patak's chutney jars, kinda squat.) Add two splashes of red wine (white might work, I dunno) and a squirt of dish detergent. Put lid on and shake the shit out of it. Take lid off, wipe rim of jar with cloth, put near fruit-fly attracting food.
When the bubbles settle down, repeat. It works best when the bubbles are even with the top of the jar.
(I've said that I don't do personal stuff. But this is Important. And besides, my co-blogger, deBeauxO, doesn't seem to be around to spank me.)
