i was planting some sod and digging the other day when i found some grubs.
they were white curled up into a ball. I live in southern ontario canada.
is it too late to spray for grubs? a guy at work said you have to spray
them in april to get the first batch, and then spray in july to get second
batch?

Is it too late to spray them now? how long will a spray last for grubs?
