The arsenicals usually will not kill them quicklyenough or in sufficient numbers noticeably to reduce theirranks. When they come in swarms, the only hope is incollecting them in nets or in an inverted umbrella-shapedapparatus provided with a vessel of kerosene and waterat the bottom to wet and kill the beetles. A few valu-able vines or trees could be covered with netting to protectthem.
