Question 1

When should the white grub treatment be done?

Accepted Answer

The treatment should be done from June 20th to mid-July.

Question 2

Why am I at risk of having white grubs every year?

Accepted Answer

Adults from neighboring properties will lay eggs the following year.

Question 3

Why can't white grubs be eliminated at the time of damage (spring and fall)?

Accepted Answer

Because when skunks, raccoons, or birds are present, the larvae have become too large to be effectively killed with the recommended insecticides for control during that period.

Question 4

Why do some companies offer treatments for white grubs now (spring and fall), and not you?

Accepted Answer

Because we focus on a much more effective preventive treatment from mid-June to mid-July. Other treatments may be offered, but control is rather weak.

Question 5

Where do white grubs come from and when do they arrive?

Accepted Answer

The adult white grub is an insect that can fly for several kilometers and can come from anywhere. Adults are present in June and July and will lay eggs in lawns around the end of June.

Question 6

What are nematodes?

Accepted Answer

They are small microscopic worms that infiltrate white grub larvae and eat them from the inside. Then, the nematodes come out and go in search of other white grubs.

Question 7

Do nematodes against white grubs work?

Accepted Answer

Effectiveness leaves much to be desired. This treatment depends on several factors such as temperature, application method, sunlight exposure, etc. Moreover, even under perfect conditions, the results are far from comparable to pesticide treatments performed from mid-June to mid-July.

Question 8

What are the damages caused by white grubs?

Accepted Answer

Discoloration of the lawn in the fall or spring with patches of grass that cannot be easily pulled up. The presence of predators: after the thaw, the larvae come to the surface, and skunks, raccoons, starlings, and grackles return or make holes to feed on these larvae. This results in torn-up grass (flipped patches).
