That's it—a fast, foolproof solution. In hours, your trap will be packed with flies, letting you enjoy pest-free meals outdoors.

No lingering odors from the meat, either—just effective control for barbecues, patios, or picnics.

Pro Tips

- Use a heated skewer, soldering iron, or sharp scissors for holes. Stay safe to avoid injury.

- Holes should be big enough for flies to enter but too small for easy escape.

- Any raw meat works: chicken, pork, beef, etc.

- For larger areas like gardens, deploy multiple traps—we use four around our outdoor table for total peace.

Why It Works

Flies zero in on the raw meat's irresistible smell, slip through the holes, but can't navigate out. They drown in the water pursuing the bait—a time-tested method backed by simple entomology.
