Lawn grubs, also known as curl grubs, are white-C-shaped grub with a brown or black head. They are the larvae of various lawn beetles and live beneath the soil surface. Commonly referred to as white curl grubs, they feed on the roots of the grass and can destroy your entire lawn within a few weeks.
Most activities of grubs occur during the warmer times of the year – from early spring, through summer, and into autumn. Lawn grubs can destroy your lawns even before you become aware of their presence. Here are different techniques how you can recognize and manage it before they create great damage to your lawn.
A pesticide with long-term effect is best for any type of lawn grubs. Since grubs are very active during nighttime, it is best to apply the herbicide before the sun sets. When they eat the grass with pesticide, they will die. It is best to employ the use of pesticide during spring and summer months because they dig deeper into the ground during winter.
• Spiked Aerator Shoes
Also known as spikes of death, you are required to wear spiked aerator shoes while walking over your lawn. This is the favorite method used to control Japanese beetle as it gives dual benefits at the same time – aerating your lawn while killing the grubs.
• Milky Disease
Milky Disease is the scientific name for an organic solution that works more effectively if you have high concentration of grubs in your lawn. The more grubs you have, the higher probability of reducing their number. Milky disease solution can reside in your lawn for an extended time so you do not need to reapply it. Moreover, researches show that milky disease only affects white grubs and Japanese beetles.
Another proven effective method to eliminate that is by using long skinny worms called nomatodes. When these nomatodes get into your coils, they attach themselves to lawn grubs until the grubs die. Studies showed that this method is fairly effective, especially if the population is quite large.
• Lawn Dethatcher
The grubs live in the thatch layer of your lawn. When using a lawn dethatcher or a power rake, it removes the thatch. At the same time, it also removes at least half of the lawn grubs consuming your lawn. After removing the thatch, you will notice that there are lots of dead grubs fused in with it. Furthermore, removing the protective layer of thatch from the soil exposes the grubs to their natural predators like birds.
