A tiny root-feeding insect that causes slow, patchy lawn decline, especially in centipede grass, with no real fix once it's there.
You'll see irregular patches of lawn turning yellow to brown and slowly thinning out, especially in centipedegrass. The grass won't bounce back with water or fertilizer. If you dig at the edge of a declining patch, you can find tiny, hard, pearl-like gold-brown cysts attached to the grass roots — that's the actual insect, and it's the only way to confirm what's going on since you never see it above ground.
Often mistaken for: Drought stress, fungal disease, or other slow lawn decline that doesn't respond to normal care
Shows up as slow, chronic decline any time during the growing season, and gets worse when the lawn is under drought stress.
Mainly affects centipedegrass lawns, though other turf can be affected too.

Bees or wasps that dig burrows in thin, bare patches of lawn—some are helpful pollinators, others can be aggressive.

Grasshoppers can chew up lawn edges near fields or unmowed areas, especially during hot, dry summers.

A burrowing lawn pest that tunnels through soil, damaging roots and leaving surface trails across the yard.

Fire ants build mounds in lawns and sting aggressively when disturbed — a real concern for kids and pets outside.
