What Is Grub Worm?Homemade Grub Worm Killer1

Grub worms, also known as white grubs, lawn grubs, or grubs, are the common names of c-shaped larvae of 30,000 species of scarab beetles. They have dark brown heads and three pairs of legs. Grubs are a nightmare to gardeners and turf owners as they feast on grassroots and other organic matter present in the soil.

Where Do Grubs Come From?

To learn where do grubs come from, you’ll have to understand the lifecycle of the scarab beetles. The lifecycle begins when an adult beetle oviposits eggs, 2-8 inches deep in the soil. After 2-3 weeks, the larvae/grubs hatched out from the eggs and started consuming roots and decaying vegetation throughout the summer. In fall, grubs burrow deep into the soil up to 1.5 meters for winter and remain dormant until the following spring. Next autumn, young grub worms again penetrate deep into the ground to live through the winter and return the following spring for feeding until they become fully grown in late spring. Next, larvae transform to the pupa stage. After a few weeks, adult beetles emerge and spend the entire winter in the soil. In the following year, May or June, they emerge from the ground and start the process again.
