Stop flies and wasps from ruining your outdoor meals. This trap screws onto any standard jam jar and turns it into an unstoppable insect catcher. The cone shape funnels bugs in but keeps them from flying back out.
The design fits jars with an 81mm opening, so it works with the glass containers you already have at home. The cone entry hole comes in different sizes to catch different bugs. Thick walls and reinforcing ribs keep it strong while staying lightweight. A rain cap with a water lip sits on top, so rain never floods your trap.
Your trap is easy to hang. Just tie a rope through the large side holes and hang it near your patio, garden, or wherever flies bother you most. It catches flies and wasps without any chemicals or messy cleanup.
