Fly Control - Water Bags



A Fascinatingly Easy Solution

Fly control with water bags is a solution that some restaurants, farms and homeowners have used with great success. Hanging clear plastic bags of water can completely eliminate fly problems and it seems to be growing in use.

One theory is that flies mistake the bags as spider webs. Something about the way the water bulging in a clear plastic bag causes a prism effect and confuses the flies. Who knows what flies think?  Maybe they just don’t feel comfortable flying around a place that hangs up bags of water. The rounder and plumper the bag, the better the fly control. Bags that get dusty or dirty need to be cleaned or replaced or they won't work. Some people recommend putting a few pennies in the bag, but water without the pennies seems to work.

Another theory is that houseflies are defenseless, nervous and don't like to sit still when they see something moving nearby, because it could be a predator. Water bags act like lenses and exaggerate the movements of people and plant foliage. Just the shifting of light and dark in the water bags could be interpreted as dangerous movement. Other insects aren’t bothered as much by the bags apparently because they have different kinds of eyesight. Give it a try - it really seems to work.
