Steveo, you are only half right. The Merit will protect Peter's lawn
from grub damage this fall (to the extent that the lawn is not already
damaged by grubs that had hatched and started growing before he
applied the Merit).

But next spring is a different story. Even if there are no grubs in
Peter's lawn this fall, there may be lots of them happily munching
away on the grass roots next spring unless Peter applies Merit again
in the spring before the eggs hatch. Remember it's not the grubs that
lay the eggs, it's beetles, and beetles can fly in from anywhere.
Merit in the grass roots this fall won't prevent beetles from
depositing eggs that lie dormant in Peter's lawn until next spring.
Right.

Hey dumbass, if he doesn't have grubs this fall, he will -NOT- have
them in the spring either.

School yourself in control products next time, before you run your
pie hole. -sheesh-

Right.

You agree with him, William?

Sorry to say, but I am not sufficiently informed on Merit.
But I certainly find the invective on this list objectionable.

Anyone who thinks grub eggs will lay dormant until next spring
is clueless.

Steveo, thank you so much for displaying your vastly superior
knowledge and for finding sufficiently vile words to describe my
rotting intellect and stinking carcass.

Perhaps, o enlightened one, you could now explain how Merit applied
too late to kill some of the grubs that hatched this summer would
prevent those grubs from burrowing downwards after their summer and
early fall feeding, remaining between four and eight inches beneath
the soil until next spring, and then rising back up towards the
surface in the spring and again feeding on the roots of Peter's grass.
(Won't this mean that, in mid and late fall, Peter's grass will appear
to be free of grubs, and yet there may be lots of them happily
munching away on the grass roots next spring? And isn't the obvious
way to prevent this the application of Dylox or something similar now,
before those growing grubs do any more damage? No, that can't be right
because you have declared:
if he doesn't have grubs this fall, he will -NOT- have
them in the spring either.)

The answer is simple, newbie. Those grubs have already pupated into
beetles..get it? Those beetles layed eggs for the next generation,
and Peter's merit application will protect his lawn from -those-
grubs.

If you don't know what the hell you're talking about, keep your
pie hole shut. You do more harm than good!

Steveo, the "mindless drivel" you snipped is carefully researched and
totally accurate. You are the one who is not getting it, so I guess
I'll have to spell it out for you very simply.

Adult Japanese Beetles appear in the spring. They fly around. They
feed on various plants. They mate. The females lay eggs in the ground,
then eat some more plants, then lay some more eggs, and so on until
they have laid maybe 50 or 60 eggs.

Typically the eggs hatch in a week or two, releasing small grubs into
the soil.

The grubs then feed all summer long on grass roots and other organic
material near the surface, and grow steadily larger.

In late September or early October, depending on the location, the
grubs burrow 4 to 8 inches downwards into the soil where they
hibernate for the winter. Once they burrow downwards the grubs are not
eating grass roots any more, but they may find some other organic
material to eat, at least for a while.

In early spring, the grubs move back up towards the soil surface. When
they find grass roots, etc. they begin to feed again. They haven't
eaten for quite a while, so they tend to eat a lot if they get the
chance.

Later in the spring, the grubs pupate for a couple of weeks at a depth
of two to four inches in the soil. They then emerge as newly formed
adult Japanese beetles.

Now let's apply this information to Peter's case, which started this
whole discussion. Peter has told us that he applied Merit to his lawn
on July 13th.

If Peter applied the Merit early enough to kill all the grubs that had
already hatched this year, he should have no problem. The Merit should
quickly kill all grubs that hatch later this season.

But if some of the grubs that hatched this year had grown large enough
by July 13th to survive the Merit, they will continue to grow and feed
in Peter's lawn for the rest of the summer. In the fall they will
borrow down to hibernating depth, and if Peter then checks the grass
roots for grubs he won't find any. But they will still be beneath
Peter's lawn, and come next spring they'll be happily chewing on the
roots of Peter's grass again.

And so when you said:
Those grubs have already pupated into
beetles..get it?

you were totally wrong. The only grubs that have pupated into beetles
this year are grubs that hatched last year.

Is late June to early July considered Spring where you live?

You said "grub eggs would lay dormant until next Spring". I
Say you're full of shit.

Learn the beetles life cycle before trying to advise people
on their control.
