SIGNS OF DAMAGE TO LAWNS
Grubs: White Grubs cause extensive damage to lawns by feeding on grass roots. Grass turns yellow, then brown and dies. Grubs chew of roots so that the grass is easily pulled up in pieces with your hands. You can roll it back like a carpet to reveal the grubs. If patches of dead grass appeared in your lawn late last summer, check for Grubs.
Billbugs: Billbug damage to lawns becomes apparent in late June through August. A heavy infestation can completely destroy a lawn. To confirm that you have a Billbug problem, grab the grass and pull up. If the stalks break easily at ground level, and the stems are hollowed out or packed full of a sawdust-like material, Billbugs are present.
Mole Crickets: Mole Crickets often cause extensive damage by tunneling through lawns. Some species also feed on roots. Tunneling uproots the grass so it easily dries out. Lawns turn yellow, become thin, weedy and can eventually die.
Other Lawn Pests: Armyworms, Sod Webworms, and Cutworms damage lawns by cutting blades of grass near the ground. Small brown patches will appear. Other lawn pests chew or suck on grass, which may cause grass to be weakened and look poor. Other lawn pests can be a nuisance outdoors.

Saw grubs in yard. Ordered this because it said kill grubs in 24 hours. Put out even more than called for and had a good rain 4 hours later in day. It has been 3 weeks since I put it out and grubs are still coming up in the little holes they make.
I have purchased the preventive (forgot the name) from you and will try putting it out the first of May to stop the babies from hatching. I sure hope this works as the armadillas wreck havock on my yard to get the grubs.
I gave this 2 stars as it was easy to put out and maybe it got a few of the grubs.
