Mole Cricket Damage in Lawns
Adult mole crickets are plump, winged and 1 to 1.25 inches long. They are seldom seen, because, like moles, they stay underground most of the time.
They fly and mate twice a year, spring and fall. At this time you will find their exit holes of an inch or more. Mole cricket nymphs are wingless but look like small adults. The nymphs can become very numerous and cause great damage to your grass during the warm summer months.
Concentrate on getting rid of molecricket nymphs!
Adults do little damage, compared to the havoc wreaked by molecricket nymphs.
As these nymphs (young versions of the adult) move from their hatch to the surface, they are hungry for their first meal.
Adult molecrickets do little damage and are very difficult to kill. All of your efforts should be on getting rid of molecricket nymphs. Not only are they the real culprits but they are so much easier to kill than the adults.
In late winter or early spring, many people make the mistake of misidentifying their lawn problem. The sight of adult molecrickets as well as spots of lawn that are dead or dying trick people into believing that molecrickets are feeding on their lawn.
The real culprit (at this earliest time of year) is usually a fungus. When questioned about their "molecricket infestation" during the first 3 months of the year, most clients say they have used a weed & feed or other fertilizer in the previous 2 to 4 weeks.
Nitrogen feeds fungus. Any lawn or turf fungi that has been laying dormant all winter will spring to life when any nitrogen fertilizer is applied to the lawn.
At first sign of lawn damage (as the grass awakes from winter dormancy) apply a granular, systemic lawn fungicide.
To kill or prevent molecrickets in lawns, first refer to the When to Apply Molecricket Insecticide information page. On the Gulf Coast, many people purchase (and apply) Talstar insecticides from late February and later. Most of these customers have to reapply insecticide in May or June -- because they insisted on treating too early. An early treatment does nothing to the super-hungry molecricket nymphs that cause the majority of the lawn damage.
If you intend on fertilizing your lawn in spring of the year, it would be wise to apply a systemic fungicide just prior to or with the fertilizer. When used for prevention, fungicides are applied at half the rate of curative measures. It costs twice as much to kill an active fungus as it does to prevent the same fungus problem.
