A horrible way to kill fruitflies

Redditor Ergas has a disgusting way to lure fruit flies to a very personal fiery death.

LPT: If you have a ton of fruit flies in your house, turn off all but one light source and wait 2 minutes. They will congregate there. Then, flick on a lighter and turn off the light source. The flies will burn their wings off trying to get close to the light source.

I had a horrible fruit fly problem yesterday
