Using fly traps is an effective and environmentally friendly method for controlling flies. Here are some common types of fly traps you can consider:

1. Fly Paper Strips: These are sticky strips that can be hung from the ceiling or placed on walls. Flies are attracted to the adhesive and get trapped when they land on them.

2. Fly Zappers: Electric fly zappers or bug zappers use ultraviolet (UV) light to attract flies and other insects. When the insects come into contact with an electrified grid, they are killed.

3. Fly Jar Traps: These traps consist of a container with a small opening, bait, and a liquid solution. The bait lures flies into the jar, and they drown in the liquid.

4. Sticky Traps: These traps are coated with a sticky substance that flies get stuck to when they land on them. They can be placed on windowsills or in areas with high fly activity.
