I have a confession to make.
I was lazy, I didn't think it would cause any harm, but it did. And now they are back. The fruit flies have taken over my kitchen, and I need help fighting them.
Story: I was preparing a must for homebrewing a batch of forest fruit wine. This all went well, the wine began fermenting and I was left with 4lb of warm soggy fruit mush. I tactically decided that the best place to dispose of this was in my inside kitchen bin. Naturally the next morning I woke up to discover hundreds and hundreds of fruit flies in my kitchen, feasting on the fly-superfood in my bin.
Question: What is the best method of killing/removing the fruit flies from my kitchen? I have already emptied, cleaned, and sterilised the offending bin, but the flies seem to be okay with not having a food source anymore. Will they eventually leave/die from lack of food? Can I drive them out with a smell or incense? Should I just commit mass insecticide and sweep them up afterwards?
