GRUBS & GRUB CONTROL
If you are noticing yellow or brown patches in your lawn that are easily torn up, you may have a grub problem.
Grubs (larvae) live in the soil of your lawn and feed off of grass roots. This causes the grass to die, thus turning your lawn yellow. Skunks and other small animals, which are digging in your lawn, is another indication that you may have a grub problem.
Grubs are bettle larvae. Grubs have six legs near the head and are usually white in colour. They feed on the roots of your lawn and plants. Grubs may attack your grass, garden plants and even any potted plants that you have.
Many grubs only cause minor damage to lawns and are not even noticeable. However, there are grubs that cause extensive damage. They eat the roots of the lawn, killing the grass and leaving brown patches that are often dug up by small wildlife.
The best way to control damage is to ensure a healthy lawn. This can be done through regular fertilizing treatments, core aeration and over-seeding.
The most effective way to control grubs living in your lawn is to apply Nematodes in early Spring and Fall.
Life Cycle of Grubs
Generally, grubs only live one of two years, depending on the type of grub.
This is a one year life cycle of a grub:
Spring - Grubs are fully grown and are feeding actively.
Summer - Grubs turn into beetles (this usually happens around June in Canada). The beetle will only live for about a week. During this time they mate and lay eggs which hatch a few weeks later.
Fall - The larvae feed until the temperature cools when they burrow deep into the soil in your lawn to avoid freezing. They remain there until spring the following year. The cycle then starts over again.
