Dealing with Lawn Pests in Fairfield County: What Newtown Homeowners Should Know

A beautiful, green lawn is a point of pride for many Newtown homeowners—but even the healthiest lawn can fall victim to pests. From chewed grass blades to brown patches and thinning turf, lawn pests can cause serious damage if left unchecked. The key is knowing what to look for, understanding how these pests operate in our region, and taking action early.

Here’s a guide to the most common lawn pests affecting Newtown and greater Fairfield County, along with tips for identifying, preventing, and treating them before they ruin your lawn.

Common Lawn Pests in Newtown, CT

1. Grubs (Beetle Larvae)

Grubs are the larvae of beetles—often Japanese beetles or June bugs—that live just beneath the soil surface. They feed on grass roots, which can cause your lawn to wilt, turn brown, and peel up like a loose carpet.

Signs of a grub problem:

• Large, irregular brown patches
  
• Grass that lifts easily from the soil
  
• Increased activity from birds, skunks, or moles digging for grubs
  

When they’re active:
Late summer through fall is peak feeding time for grubs in Newtown. They overwinter in the soil and may reemerge in spring.

What to do:
Apply a grub control treatment in late June to early July, before larvae hatch. Preventative treatments are more effective than reactive ones. Consider using products with chlorantraniliprole or beneficial nematodes as a more natural option.

2. Chinch Bugs

Chinch bugs are tiny insects that suck the sap from grass blades, causing them to turn yellow and die. They prefer sunny, dry areas of your lawn and tend to strike during hot summer months.

Signs of a chinch bug infestation:

• Yellowing or browning grass in patches
  
• Damage that spreads quickly during dry, hot periods
  
• Grass doesn’t green up even with watering
  

When they’re active:
Late spring through early fall.

What to do:
Keep your lawn healthy with proper watering and mowing. If chinch bugs are present, treat affected areas with an insecticide labeled for surface-feeding insects, or consider a natural approach using diatomaceous earth or neem oil.

3. Sod Webworms

Sod webworms are the larvae of small moths. These caterpillars chew on grass blades at night and hide in silk-lined tunnels during the day. Damage usually appears as small brown patches that can rapidly expand.

Signs of sod webworms:

• Small brown patches that enlarge quickly
  
• Grass blades look chewed or ragged
  
• Moths flying low over the grass at dusk
  

When they’re active:
Late spring through early fall, especially in July and August.

What to do:
Mow your lawn regularly and avoid overwatering. If needed, apply a surface insecticide specifically labeled for sod webworms.

4. Ticks

While ticks don’t directly damage your lawn, they pose a serious health risk to people and pets by transmitting diseases like Lyme disease. Ticks are commonly found in tall grass, brushy edges, and shady, damp areas.

Where they thrive:

• Along tree lines
  
• In uncut grass
  
• In shady, damp zones under trees or hedges
  

What to do:
Keep your grass mowed, trim back shrubs and tree branches, and consider using tick control treatments around the perimeter of your lawn. Mulch barriers can help separate wooded areas from lawns to reduce migration.

Prevention Tips for Lawn Pests in Newtown

Staying ahead of pests is easier than trying to eliminate them after the fact. Here are some proactive steps to protect your lawn year-round:

1. Mow high and often. Taller grass promotes deeper root systems and provides less ideal conditions for pests like chinch bugs and webworms.
   
2. Water deeply, not frequently. A healthy lawn is better able to resist pest damage. Water early in the morning to prevent fungal issues.
   
3. Aerate and overseed in fall. Thick, well-aerated turf leaves little room for pests to take hold.
   
4. Get a professional soil test. This will help you understand your lawn’s nutrient profile and make informed fertilization choices—stronger grass resists pests naturally.
   
5. Monitor regularly. Walk your lawn weekly during the growing season to look for early signs of stress or pest activity.
   

Should You Hire a Professional?

While many lawn pest problems can be managed with DIY methods, sometimes the damage is too widespread or persistent. A professional lawn care provider can help identify the specific pests, apply targeted treatments, and put a year-round plan in place for prevention and recovery.

Hiring a local expert is especially helpful in areas like Newtown, where changing weather and dense foliage can create a unique set of pest challenges. Professionals can also ensure environmentally responsible treatment methods that align with local regulations and protect our waterways.
