Without its natural checks and balances, the Japanese beetle has become a serious plant pest and a threat to American agriculture. Females live for a few weeks feeding on trees, shrubs and roses in the morning, returning to the turf in the afternoon to lay more eggs. This form of life cycle is called complete metamorphism. The beetles can’t resist their leaves and it kills them. However, it should be noted that traps will only help prevent the adults from feeding on certain plants and shrubs.
