Chinch Bug & Lawn Insect Treatment
Chinch bugs, sod webworms, armyworms, and billbug adults all feed at or just below the grass surface. Damage looks a lot like drought stress, so it often gets the wrong treatment.
Damage that looks like drought, but watering will not fix it
Surface-feeding insects live and feed at or just above the soil surface. They suck plant juices from grass blades or chew the crown, and the result looks almost identical to drought damage: irregular patches of yellowing grass that turn straw-brown and do not recover after rain.
The wrong read here is expensive. More water will not save a lawn that is being eaten. Our surface-feeding insect management service starts with correctly identifying which pest is actually present (chinch bug, sod webworm, or armyworm), and then treats only where the population is active.
Identify first, treat second
These insects each have their own signature. Catching which one you have changes the timing and the approach.
Walk the damage, name the pest
Chinch bugs hide at the soil surface. Sod webworm moths flush up when you walk the lawn at dusk. Armyworms strip an area fast, then move. We identify before treating.
Targeted surface treatment
When treatment is warranted, we treat the zones where the insects are actually active, not the whole lawn. Products selected with pollinator awareness in mind.
Hot and dry favors these pests
Chinch bugs thrive in hot, dry conditions. Healthy, well-watered turf is less attractive to them. Fertility and proper watering practices are part of the long-term answer.
IPM-first approach
We watch thresholds instead of treating on a calendar. If the pest pressure is not there, we skip the treatment and save the chemistry for when it is actually needed.

Surface-feeding insect FAQs
The questions we hear most when walking customer properties for damage assessment.
Do you offer chinch bug control and lawn insect control?
Yes. "Chinch bug control" and "lawn insect control" are the phrases people search for. We file this under surface-feeding insect management because chinch bugs, sod webworms, and armyworms all feed at the grass surface and need the same identify-first, treat-only-where-active approach. Same service, whatever you call it.
How do I tell if my lawn has chinch bugs or just drought damage?
The damage looks identical at first. Both produce irregular yellow-to-straw-brown patches in hot, sunny areas. The test: pour a cup of soapy water on the edge of a damaged patch. If chinch bugs are active, you will see tiny black-and-white insects come to the surface within a minute or two. Drought damage will not produce any insects.
Another tell: drought damage greens back up within a few days of a deep watering. Chinch bug damage does not, because the grass is being eaten while it is being watered.
When are surface-feeding insects most active in Maine?
Mid to late summer for most species. Chinch bugs thrive in hot, dry stretches from July through August. Sod webworms peak in August. Armyworms can show up anytime from July through September depending on the year. We monitor through the active window rather than treating on a calendar.
Should I treat the whole lawn or just where the damage is?
Just where the activity is. Surface-feeding insects concentrate in specific zones (hot, dry, sunny areas first), and treating the whole lawn wastes product on areas where there is no pest pressure. We treat the active zones and a buffer around them.
Are these treatments safe for kids and pets?
Our products are selected for a favorable profile around people and pets when used as intended. Keep kids and pets off treated areas until the product has dried (typically 1 to 2 hours). Once dry, the treated zone is safe for normal use.
Will more watering save my lawn from chinch bugs?
No. Watering helps the grass recover faster after the insects are managed, but it will not stop the feeding while it is happening. A lawn under active chinch bug attack needs both: targeted treatment to stop the feeding, plus consistent watering to support recovery.
How long until the lawn recovers after treatment?
Healthy turf with deep roots usually fills back in over 4 to 6 weeks once the feeding stops. Severely damaged areas may need overseeding (fall is the best window in Maine) to recover fully. If the damage is extensive, we will recommend pairing the treatment with a fall overseeding plan.
