the leatherjackets will eat the roots of the grass thus making your lawn
patchy spraying is the only way to control and crossfire pesticide doesnt
harm birds

Hi Lisa,
A few years ago, just after I had purchased my home, I noticed
leatherjackets and was worried, much as you are, about the damage they
might
cause to the lawn.
I did a controlled experiment: I sprayed only half of the front lawn
with a pesticide recommended by a garden shop.

Result: the larvae came to the surface on the sprayed half and were eaten
by
sparrows and I assume, some were taken to feed their young.....I tried to
chase the birds away but they were determined...

End result with my lawn: The sprayed part and the unsprayed part looked
exactly the same. I never sprayed again.

PS: Side note and shooting from the hip: In the fall when the
leatherjackets
hatch they provide food for the birds that are heading south. They need
that
food if they are to survive the long journey and for the birds that stay,
it
probably is required by them to build fat for the long winter.
Bottom Line: Nature has a way of looking after 'stuff' so long as we let
her...
