Japanese and June Beetles


june beetleWhen you have beetle larva in your lawn, these are typically referred to as white grubs. White grub can destroy your lawn if there are large populations of them in your yard. There are essentially two different ways to protect your lawn from having grubs. The first way is to keep your lawn as healthy as possible. Having a healthy lawn help will prevent grubs in lawn from destroying your grass. The second way is to make sure that you do not have a lot of dog poop left on your lawn during the summertime. This is when beetles tend to lay their eggs, and a favorite place for them to lay is in petrified dog dung. By keeping your lawn clean and free of dog poop, you make it harder for them to appear in large populations in your lawn.

Lawn grubs tend to do most of their damage either in the fall or in the spring. During the summer, they are mostly adults, and during the winter, they tend to hibernate. If you will be effective at killing lawn grubs, you need to know more about their life cycles and when to treat them.



If you have a lot of June beetles in your lawn, you should know that the best time to treat grubs in lawn is in the late spring before they start to mold and turn into adults. If you have Japanese beetles in your lawn, you will have better luck treating them in the fall. The reason is because Japanese beetles are pretty much done growing at the end of the fall. At this time they mold and over the winter they slowly turn into adult beetles. They emerge in the spring time as adults. Your optimal window for killing white grubs is when they are in the grub stage of development. If you are going to kill them using insect growth regulators, then you probably want to put these down right before they start to molt. This way, you can keep them from becoming adults and reproducing. This will help to control grub worm populations in the future. Insect growth regulators tend to be more effective on grubs than other types of pesticides, because grubs typically live one to 3 inches below the surface of the soil. This makes them harder to kill with regular pesticides that don’t go that deeply into the ground.
