Iv not had problems before with the lawn. It is just this year that it is dying off but I have noticed a lot of holes in the ground hence wondering if it is insect related?
Chlorpyrifos. was banned a few years back for the turf trade and farmers, as an Insecticide. I expect Leatherjackets numbers to go up year by year.
For a quick check water a meter square heavily and then cover with a sheet or plastic and the check early morning, you should then get a idea if you have large numbers.

As MrMow suggests, there are ways to assess the problem.
