How to Trap and Kill Japanese Beetles? A Full Guide to Practical Control Methods

Hang 1 light-colored glass bottle every 3 to 4 trees, such as a beer bottle or a wide-mouthed medicine bottle. Wash the inside of the bottle clean, catch 2 to 3 live Japanese beetles and put them into the bottle, tie a rope around the neck of the bottle, and fasten it to a fruit tree branch, with the bottle mouth 2 cm from the branch. Japanese beetles have a gregarious habit and will crawl into the bottle one after another. Once the bottle is full of beetles, take it down and scald them to death with hot water.
