RESCUE! Outdoor Disposable Fly Trap — 2 Traps

This pair of hanging fly traps uses a powerful attractant bait designed to draw nuisance flies away from outdoor living spaces. It’s best for small to medium patios, trash areas, and yards where quick setup is preferred. The bait activates with water, releasing a scent that lures common flies into the bag, which then traps them.
Best for: small decks, gardens, and spaces needing rapid fly reduction without complex installation. Better for: quick deployment and easy disposal. Avoid if: you need long-term, high-capacity coverage in very large areas since two traps may be insufficient for heavy fly pressure.
