Most bugs are good bugs, and have an important role to play in the garden. Pollinators, in particular, come in all shapes and sizes. But there are times when too many bugs, like wasps, in one place become a nuisance or even dangerous. In those cases, you want to reduce the risk of being bitten, or worse, in the most earth-friendly way possible. This bottle-cap trap is a good option, especially for picnics, camping, and similar outdoor activities, and can be used to target a variety of insects. Mix up the appropriate bait (not included, there are many recipes available online), screw your bottle into the trap, and hang it up wherever biting bugs are a problem.
