The chafer grub is the larva of the chafer bug or june beetle

Latin name: Melolonthinae

Signs of infestation:

The larvae that cause damage to lawns. The signs of their presence are unequal plates yellow or dead grass that can detach easily and holes in the lawn dug by skunks or raccoons, fond of these insects. We see the damage appear in early spring and early August.



They are beetles that come out in the evening or at night, sometimes called ” barbel ” They have dark brown and shiny shell and they are between 10 and 13 mm long. They have a loud and characteristic flight.

– Big worm creamy white with tiny hairs, brown head,

– Body bent into a ” C ”.

– 3 pairs of legs often a little darker.

– Size: 2-4 centimeters long.


These insects breed on a twelve-month cycle so they spend the winter underground.

From mid-June to mid-August the adults lay their eggs in the grass, the larvae will hatch two or three weeks later and they will gorge on roots for accumulating energy necessary for their growth and their overwintering. In mid-October, larvae descend deeper into the ground (25 cm or more) for the winter. In spring, when the snow melts, the larvae wake up and just go back in the grass to eat as much of the roots again. When they are force-fed, they descend deep into the ground once again to transform into adult will emerge from the earth between mid-May and mid-June to begin the cycle.

Adults are not harmful and seem to prefer among others, the nearby fruit trees, silver maples and birches. Their nocturnal flights are used for acccouplement and females mated once will immediately lay their eggs.

The larvae, they constitute the real problem, they feed on grasses and hardy plants but their favorite places is the bluegrass of Kentucky, ie the grass of your lawn. They are terribly greedy and they literally cut the roots of the grass blades at one or two centimeters under the ground.

The best prevention for white worms is to keep a healthy lawn and provided at all times. (Make fertilizer). Moreover, it is advisable to leave the grass longer 8 cm or 3 inches) during adult flight. (Mid-June to mid-August) and not to over water when the eggs and young larvae are present, ie from mid-July to mid-August … We also recommend you to plant clover or other hardy species instead of your lawn. It may sound unbelievable but that’s what the experts recommend.

If you find more than 5 per square foot to the damage to your lawn can be considerable.

The grass is a plant that was imported by the English to be able to mimic the gardens and castles of England requires “huge amounts of water for maintenance and often fertilizer to become very thick. We must come to the obvious: the advice you are given for removal of naturally white grubs are contradictory and unhelpful. The longer you let the long grass, the more it will require water to maintain it and if you water less as you recommended, it will wither more quickly than white grubs. The fertilizer we suggest you épendre on your lawn may as well go down into the groundwater and contaminate water and affect more than insecticide.

Nematodes also is recommended to use, small parasitic insect grubs. This is interesting in appearance, but treatments are expensive and according to rudeur winters, they die in large part to kill and not enough to make a difference.

You should also know that © Merit, trade name of the insecticide Imidacloprid is that most white to processing companies use to solve the problem. It is part of the neonicotinoid family, a variety of pesticides banned in the European Union because of its terrible effects on bees and other pollinators. This insecticide into the plants and poisons the insects that nourish.

Liquid insecticides used by lawn care companies are not good solutions for the rain (quite common in Quebec) dilutes its effect, moves on the lawn and makes it less effective to the exact spot where he had to act .




Because of our changing seasons, we understand that it is impossible to ask you to cut your or long grass and watering your lawn more or less than one week to another.

We believe the benefits of insects and we will not kill bees and other pollinators.

THEREFORE: We propose to get rid of your grubs with a smaller dose of a granular residual insecticide, which gradually dissolve in rainfall patterns in your lawn and will degrade in the environment later. It has been proven and is safe for bees and we will spread the only places at risk or affected.

Surface treatments must be made by experts because they must comply with government regulations and municipal regulations.
