Suspended in the area, it will distract on itself, annoying insects, and gardening can be destructive to pests. The secret simple trap, judge for yourself.
In a flat tin can (e. g., herring) filled with oil, and the middle is a vessel with a decoction of flowers or fruit, acting as a decoy. Above the bulb is attached improvised foil umbrella in case of rain.
The whole trick. Attracted to the light and the scent of insects, striking, falling into oil, becoming an added lure.
