I have developed a large brown patch (aprox 200 sq. ft.) in the middle of my
otherwise healthy and green lawn. I suspect grubs, but dug up a few places
and found none. (This might have been because the lawn is already dead, the
grubs have moved on.)

Before I blast the area with grubicide (or whatever it is) does anyone have
any advice on a) verifying the problem, and b) treating it, c) getting back
to "green"?

Thanks,

Look at a extension service website for your area. The last advice I
read in looking for grubs was to lay back a square foot of sod and count
the grubs that you find. Can recall what number is acceptable per sq ft
- three?

Has this been a gradual or sudden problem? Warm climate? Mole crickets
here in Florida can scalp a lot of lawn. One method for finding them is
to saturate about a sq foot of sod with soapy water - tbsp of
dishwashing detergen per gallon - wait and see what comes up for air.
Interesting experiment, as it causes even earthworms to struggle for air.
