Whites grubs
Grubs eat the roots of many
plants but mostly lawn roots. This will
make your lawn become yellow, soft and
spongeous. A group of larvas can destroy
a square foot per day and cause lots of
damages. Il you can gently flip the
grass over, you`ll see hoe the larvas have
attacked your lawn.
On a lawn that is irigated
properly, the presence of 5 to 10 larvas on a
square meter is bad. Skunks, racoons may
cause a lot of damages to lawns infested with
grubs, because they like them. They will
turn the lawn and dig holes up to 15cm (6
inches) to get them.
This insect life has 3 phases.
The white worm is a small larva that will feed
on the grass roots until the end of November.
As soon as the temperature drops, it will go
deeper in the soil and stay there for winter
season.
When spring is there, the
larvas go back in motion and will stop heating
around half of the month of May and then
mutate. Two weeks latet, the adult bug
get out and can now fly. It will
reproduce in moist locations like ledge, house
gutters and other. The female will lay
her eggs in the hot soil of lawns. Three
weeks after the eggs will hatch and the white
worms will come out and the cycle start over
again.
It`s been a few years now that
grubs spreaded to Montreal and the surrounding
regions. The insect came with the
shipping of roses from Europe to the USA
around 1940 and then propagated to Ontario
around the beginning of 1960 and then in the
Montreal region around 1986. It`s been
about 5-6 years now that people noticed a big
increase in the damages caused by the grubs.

lawns affected by the grubs.
