When you notice thinning grass, brown patches, or other damage to your lawn, you might assume that extra watering and fertilizer will help it recover. While these are essential parts of a lawn maintenance routine, the actual culprit could be hard-to-spot lawn pests. Today, we’ll explore the three biggest surface insects that harm lawns in Rapid City, South Dakota, and how to protect your turfgrass from these destructive pests.
Top Lawn-Destroying Insects in Rapid City, SD
1. Sod Webworms
Despite their name, sod webworms aren’t worms but small, winged insects. Often called “lawn moths,” adult sod webworms are tan-colored moths measuring about 1/2 to 3/4 inches long, with long snouts and delicate wings. However, it’s their larvae that damage your lawn. These brownish-gray caterpillar-like larvae grow to about an inch long and spend the winter hiding in web-lined tunnels within the thatch layer of turfgrass.
The larvae feed on grass leaves and stems at night, causing significant damage. By morning, they retreat to their tunnels to avoid predators.
Signs of Sod Webworm Damage
- Brown patches that resemble scalped grass.
- Patches that grow larger over time if untreated.
- Activity is highest from early spring to fall.
If you suspect sod webworms, don’t wait. At Warne Chemical, our lawn pest control services target sod webworms and other pests to protect your yard.
2. Billbugs
Billbugs are another common pest mistaken for grubs due to their similar larvae. These pests cause irregularly shaped patches of dead grass, especially in midsummer. Adult billbugs are gray or black beetles about 1/4 to 1/2 inch long with a distinctive snout. Their larvae are white, legless, and slightly more rotund than traditional grubs.
The real damage comes from the larvae, which feed on the stems, crowns, and roots of turfgrass.
Signs of Billbug Damage
- Dead grass patches near sidewalks, curbs, or other edges.
- Turfgrass that can be peeled back easily, revealing larvae underneath.
- Visible adult beetles in surrounding areas.
Our lawn pest control treatments can identify and eliminate billbugs before they cause significant damage to your lawn.
3. Grubs
Grubs are among the most notorious lawn pests in South Dakota. These c-shaped white larvae are the offspring of Japanese beetles and other scarab beetles. They live beneath the soil surface and feed on grass roots, leading to widespread damage if left untreated.
Signs of Grub Damage
- Thinning Grass: Brown, dying patches that don’t respond to watering or fertilization.
- Grass Peel Test: Grass that lifts easily, like unrooted sod, due to damaged roots.
- Spongy Texture: Walking on grub-infested lawns feels like stepping on a rubber mat.
- Uneven Lawns: Puddling water or bumps in previously level areas.
- Animal Activity: Increased digging by birds, skunks, or raccoons searching for grubs.
Don’t let grubs turn your yard into a feeding ground. Our pest control services provide fast, effective grub treatments to restore your lawn’s health.
