What it does

  • Attaches to standard soda bottle threads, use any Coke or soda bottle you have
  • Funnel design traps flies and wasps inside; they can't find their way out
  • For flies: add fish scraps and water; for wasps: use beer and water mixture
  • Reusable and eco-friendly, empty, rinse, and refill instead of buying traps
  • Ideal for gardens, camping trips, and outdoor excursions

This reusable fly and wasp trap screws onto any standard soda bottle, turning a household item into an effective pest control solution. The funnel-shaped design draws insects in with natural attractants, but their instinct prevents them from finding the exit, a simple, chemical-free method.

For fly control, insert sardine pieces and fill the bottle three-quarters with water. Hang it about 1.5 meters high away from your house. After 3-4 days as the fish decomposes, flies will be attracted in increasing numbers. Once full, simply empty half the contents, add water, and reuse, no need to replace the bait.

For wasps, skip the fish and mix equal parts water and beer with optional sugar. Wasps respond immediately, making this trap perfect for camping and outdoor gatherings. Keep the original bottle cap to seal and dispose of the trap when done, or empty and refresh it for continued use.
