One of the most destructive bugs in yards of any type is the white grub. White grubs are also called annual white grubs or grub worms. They destroy turf by eating the roots of the plant as well as upsetting the soil with their continuous search for eatable roots. Since these pests are so destructive, you must know when to treat for grubs.
The digging by grubs is frustrating. But numerous creatures eat grubs when the grubs are active. Grubs are usually active in the late summer through autumn.
When to Treat for Grub Species
In North America, there are over eight species of white grubs. The accidentally introduced species are the European chafer, oriental beetle, Asiatic garden beetle, and the Japanese beetle.
Most grubs have a 12-month life cycle. Some white grubs have a 24 to 36-month life cycle. A life cycle for grub is called metamorphosis.
Grub Life Cycle
1. Start life as an egg, positioned in the soil 1 to 4 inches deep down
2. Eggs take in water from the surrounding soil to stay worthwhile
3. After 2 to 3 weeks, eggs hatch into tiny grubs
4. Begin eating delicate organic matter and root hairs
5. Keep feeding until early winter. As the temps fall, grubs move deeper into the soil
6. Reemerge in early spring, do some light feeding, and then pupate in the soil
7. After a couple of weeks, adult beetles surface to lay eggs, and the whole life cycle starts again
The time to treat for grub control is from August to June. Most of the grub control products available operate best as a preventative measure. If you want to apply the product yourself, make sure you read and adhere to label rates and directions. Grubs feed and live in the soil. Therefore, the product must be watered entirely into the ground and grass to get to the grubs.
