Live in NJ and spring seems to be here. At the end of last summer, we
noticed a grub problem where a big patch of our lawn was dead...had to
rake it all out (grubs were abundant) and reseed the area. Any
suggestions on how to prevent this from occuring again? Are there any
prevention treatments that work well?


I agree with Peter H. Merit works very well. It's very important to
apply the product at the right stage, or instar, of the grubs' life cycle.
See your coop extension agent or read up on Merit from its manufacturer.
A combination of nematodes and pesticide works, too, according to
http://extension.osu.edu/~news/story.php?id=2152.

You likely have several different types of grubs munching your lawn's
roots. The only reliable way to differentiate between them is to grab a
magnifying glass and check for certain things like the arrangement of
particular hairs on its body. Too involved for a layman that just wants a
better lawn.
