The Japanese Beetle is an insect that is quite damaging to lawn and gardens, as they can eat up your flowers and other plants quite quickly. These beetles are serious pests when they are adults, but they lay eggs in early to mid-summer. These eggs hatch and these tiny creatures quickly mature into grubs. While adult Japanese Beetles will skelatize your plants, their grubs can decimate your lawn.
You probably won’t notice the presence and handiwork of these grubs until summer, because the grubs live under the soil and eat the root tips of the grass in your lawn.
