I live in northern Illinois. We've had very little rain. We go a
couple weeks with zero rain, then get a downpour of an inch or two,
which is great, actually.

This year we had the most massive Japanese beetle infestation I have
ever seen! Before I knew what hit me, three of my trees were
completely brown.

So, how do I take care of grubs? Will the beetles' eggs hatch this
year, or will they hatch next summer/spring?

From what I've read, Grub X is very dangerous. We have young children
and a dog, so I don't want to use dangerous chemicals.

Another problem is that I have 2 acres and no irrigation., and with no
rain in the forecast, it would be impossible to water anything in.

Can I wait until next spring to treat for grubs? Will a treatment
kill the eggs, or do the grubs have to be hatched and active?
