These are the most important roots to your plants. The plants depend on these little fibrous roots to pick up the water and nutrients necessary to maintain healthy plants and lawns. The Japanese Beetle was accidentally introduced to the United States in a shipment of shrubbery from Japan to New Jersey around 1916 and now inhabits almost two thirds of the country. It's infestation extends from Maine to Southern Georgia and from the Atlantic coast to the Mississippi with outbreaks reported in Nebraska, Kansas, Missouri, Texas, California, and Washington state in 1996. There are many different ways to attempt to control Japanese Beetles.
Many people use beetle traps to catch and kill beetles in their yards and gardens.
No doubt these beetle traps are effective at luring and trapping beetles, I've seen them hanging with the bags almost full. Not a very pleasant site, and I am sure much less pleasant to empty or dispose of. More than we would like to think about I am sure. Not to mention the beetles from your neighbors yard that were lured across the border by the bait in the beetle traps. Some professionals claim that beetle traps do more harm than good because they attract beetles to your yard that wouldn't have come without being lured.
