I just spent about 30 minutes swatting fruit flies with an electric flyswatter.

I made a trap for work, it was a huge dorm building and the laundry people left trash in the bathrooms in the basement after the students moved out and it caused a swarm of fruit flies in the building. I brought a banana to work and put a chunk in several jars and they’d collect on them in a few hours, take the jar to the bathroom sink and put water in it and drown them. Reuse the bananas for catching more fruit flies. Took care of the problem in less than 2 days.

why kill them just leave windows open and they will take the hint and go 😄[captainjackass]

Throw a bug bomb in, then seal off the bottom of the door.

You should probably clean your toilet

Take a microwave-safe bowl and fill it with apple cider, add a couple of drops of dish soap, then zap it for a few seconds before placing it in your bathroom. The soap will create just enough surface tension that the flies will try to land on it, and they'll drown.
