I applied the crabgrass preventor about a month ago, and wish to put
down some insect killer on the lawn now to keep the grass bug free for
when the kids play on it. Will this break that protective barrier that
they say the preemergent gives to the lawn?
I don't think an insecticide will interfere with the operation of a
pre-emergent herbicide. At any rate, you can look at the instructions
for your pre-emergent herbicide and see how long it says to wait
before it is safe to sow grass seeds. After that amount of time you
don't have to worry about anything affecting it. The way a pre-
emergent typically works is that it is absorbed by seeds, and causes
them to die when they germinate.
On the other hand, I don't know why you want to use insecticide on
your lawn, especially if your kids play there. I'd worry more about
the poison chemicals than I would about the bugs.
yeah.. I agree and I do use chemicals IF there is something that is really out of

First identify which insects you are after. Then select the product
that targets those insects and READ THE LABEL.
Many of the insects that you are concerned will bug your children are
not in the ground to begin with but fly into the area. Treating the
soil will do nothing to prevent these.
