What’s green and buzzes all over? The answer to this question is not as amusing as you think. The answer is Japanese beetle, also known as Popilla Japonica. These beetles invade homes and gardens in the months of May, June, or July. They eat up your garden plants, and create a mess wherever they go. Did you know that an adult of this species eats up to 400 plants in a year? This is quite a situation, and hence, this article will teach you how to avoid it.
First discovered in New Jersey in 1916, these pests have spread to most northwestern states of the US. America’s climate seems to be favorable for them. Stories say that they probably arrived through some plants that were imported from Japan. Once these plants were planted in the US soil, these beetles quickly gained advantage, and spread all around. Their life span is around 1 year, and the females lay more than 200 eggs in that much time. They love feeding on roses, birch trees, dogwoods, and cheery trees.
