“We are getting reports from some gardeners that Japanese beetles are showing up now,” said John Farfaglia, extension educator with Cornell Cooperative Extension in Niagara County.
The Japanese beetle, which is native to Japan, is a highly destructive plant pest here. In Japan, natural predators keep the population in check.
Hand picking works well in small gardens but must be repeated frequently, Farfaglia said. Neem oil is also an option for control.
