Vacuum fruit fly catcher.

Vacuum fruit fly catcher.


A small shop type vacuum contains a small amount of soapy water. The vacuum is activated periodically by a timer. The vacuum draws air through a hose attached to a container that has a series of small holes in the top. In the bottom of the container is a sponge soaked in wine or fruit juice. The fruit flies land on the bait sponge and collect there for a period until the timer starts the vacuum running for a few seconds. The flies can't fight the vacuum draw and are sucked into the soapy water and are killed. I've used this home made devise very successfully in my wine making area.
