Mole crickets surface-tunnel through turf at night, uproot seedlings, and leave raked-looking trails of disturbed soil across a lawn. The key to getting rid of them is timing and product choice — spraying a whole lawn at the wrong life stage is time and money wasted.
Confirm the problem first. Mole-cricket damage shows up as surface tunneling, thinning turf, and disturbed soil. Mark the active areas instead of treating everything; University of Georgia Extension guidance in Mole Crickets in Turf (publication C-918) stresses targeted treatment over routine whole-lawn application, with spot treatment and baits reasonable for lighter damage.
When Should You Treat for the Best Results?
If you have only light spring damage, mark the adult-activity areas and treat after the hatch instead of spraying immediately. Mole crickets are most active at night, so apply as late in the day as possible — heat and sunlight cut product performance.
The Step-by-Step Treatment
Work the sequence cleanly and the label does most of the work for you.
| Step | What to Do | Label Detail |
|---|---|---|
| 1. Confirm | Mark tunneling and damaged turf | Treat only affected zones |
| 2. Prep soil | Irrigate dry soil before treating | Brings crickets to the surface |
| 3. Apply | Spread labeled granular evenly | 2.4–4.8 lb per 1,000 sq ft |
| 4. Water in | Irrigate right after application | Up to 0.5 in. on bifenthrin 0.2%G |
| 5. Recheck | Watch for renewed activity | No more than once every 7 days |
| 6. Retreat | Only if activity returns | Rate depends on formulation |
| 7. Escalate | Larger nymphs need higher label rate | Follow the product label |
Pick only an EPA-registered product whose label lists mole crickets for your site — examples include Bifenthrin 0.1% Lawn Granules, Bifenthrin Granule Insecticide, Bifenthrin 0.2%G, and Lawn Granular Insecticide. The EPA label for Bifenthrin 0.1% Lawn Granules specifies 2.4–4.8 pounds per 1,000 square feet for mole crickets, applied late spring and watered thoroughly immediately afterward.
Water in right away without runoff. The Bifenthrin 0.2%G product label specifies up to 0.5 inch of water after treatment, and the Bifenthrin Granule Insecticide label limits retreatment to once every seven days and only when renewed activity appears.

For larger, later-season nymphs, the EPA notes higher labeled rates or more frequent labeled applications may be needed. UGA warns that late-fall control is difficult and should target only extensive or critical damage.
Which Mistakes Waste the Most Money?
The costliest slip is treating the entire lawn when damage is localized — spot treatment protects both your wallet and the grass you’re trying to save. Applying during the day instead of evening, skipping pre-irrigation on dry soil, and failing to water granules in immediately all waste the product you paid for.
Treating before the relevant egg hatch misses the more vulnerable young-nymph stage. Reapplying without renewed activity, or more often than the label allows, is another fast way to burn money and risk over-application. Using an outdated label, an unregistered product, or a rate from a different formulation is a mistake that can cost you the whole treatment.
Don’t assume adult control is durable. Both the EPA and UGA note that continual adult invasion can make sustained control genuinely difficult, so expect to keep monitoring.
Every pesticide label is legally controlling. Verify the current product label, active ingredient, concentration, approved sites, spreader directions, PPE requirements, reentry restrictions, and environmental precautions before you apply. Never treat simply because a product controls “lawn insects” — mole crickets must be explicitly listed for your site. And never exceed the label rate, combine products unless permitted, apply during runoff conditions, or retreat on a schedule the label doesn’t support.

Common Questions
What time of year should I treat a mole cricket problem?
Spring and fall applications can work but often miss that vulnerable window, so time your application to follow the hatch rather than treating on a fixed calendar date.
Do I have to water the granules in after spreading?
Yes. EPA labels for bifenthrin granular products direct irrigation immediately after application, and one Bifenthrin 0.2%G label specifies up to 0.5 inch of water. Watering moves the active ingredient into the soil where mole crickets live — skipping it leaves product stranded on the surface and substantially cuts its effectiveness.
Why does mole cricket damage keep coming back?
Continual adult invasion from surrounding areas can make control difficult to sustain, as both the EPA and University of Georgia Extension note. Recheck treated zones for renewed activity and retreat only as the label permits. If damage is severe or recurring, a local County Cooperative Extension office can advise on regional timing and product options.
