A Tiny Bug, A Big Warning: Decatur County Farmers on Alert as Invasive Pasture Mealybug Arrives in Georgia

Pull up a chair. There's something important every farmer, rancher, and landowner in Southwest Georgia needs to know about this season.

A new invasive insect has been confirmed in Decatur County for the first time — and officials are asking everyone who grows or maintains grass to pay close attention. It's called the pasture mealybug (Heliococcus summervillei), and while it may be small enough to miss with the naked eye, the damage it can cause is anything but small.

What's Happening Around the Village

In late July 2026, the pasture mealybug was discovered on weeds and grass at a turfgrass farm in Decatur County. The U.S. Department of Agriculture officially confirmed the detection on August 5, 2026 — making Georgia the latest Southern state to report the pest after Texas, Louisiana, and Florida.

Georgia Agriculture Commissioner Tyler Harper responded quickly, urging farmers and producers statewide to stay vigilant. "Pasture mealybug is a serious threat to Georgia agriculture," Commissioner Harper said. "This pest can spread quickly and kill grass, potentially causing significant losses for our farmers and making biosecurity more important than ever."

The pest is native to Southeast Asia. Researchers believe it hitched a ride on storm winds from the Caribbean — where it established a presence around 2020 — and has since swept across the American South with alarming speed. As of mid-August, the mealybug had spread to 70 Texas counties. It hit Louisiana sugarcane fields last fall and confirmed itself in over two dozen Florida counties by summer 2026.

Why It Matters

This isn't just a pest problem — it's an economic threat. Georgia's beef industry generated $1.2 billion for the state's economy in 2024. Turfgrass production added another $284 million. Both are built on warm-season grasses, and the pasture mealybug feeds on exactly that.

The bug damages grass by sucking sap, injecting toxic saliva, and producing a sticky honeydew that promotes mold. Signs can show up within a week: yellowing grass that turns purple or red, stunted growth, drought-like stress even after rainfall, and eventually — plant death. Females can produce nearly 100 offspring in 24 hours, and there can be three generations in a single year.

"This pest is unlike anything else we have dealt with in the region. It has the potential to be incredibly detrimental to grass-based agriculture," said Dr. Lisa Baxter, UGA Extension State Forage Specialist. "There is a lot we still don't know, but rest assured that our team is doing what we can to learn more and keep everyone informed."

The threat extends beyond pastures. Corn, wheat, sugarcane, rice, sod farms, hay fields, and even ornamental grasses could all be affected. As Dr. Baxter puts it: "People forget that things like corn and wheat are grasses."

How This Impacts Our Community

In Decatur County and across Southwest Georgia, agriculture isn't just an industry — it's a way of life. Cattle ranchers, hay farmers, sod growers, and small family farm operators form the backbone of our communities. A sustained infestation of pasture mealybug could mean lost grazing land, damaged hay supplies, and real financial hardship for families who have farmed these fields for generations.

Georgia's cattle herd is already under pressure — recent years have brought drought, rising input costs, and national trade challenges. The last thing local ranchers need is a fast-spreading invasive bug decimating the very grass their herds depend on.

Homeowners and community members with regularly mowed lawns are at lower risk, according to UGA entomologist Dr. Shimat Joseph, who noted that well-maintained grass in Australia resisted serious damage. Still, keeping an eye out matters — because slowing the spread is a community effort.

How You Can Get Involved

Here's what farmers, landowners, and community members can do right now:

• Walk your pastures and hayfields regularly. Look for yellowing, stunted, or dying grass patches — especially in warmer, wetter areas. Mealybugs may appear as white, fluffy spots near the base of grass plants.

• Report suspected sightings immediately. Contact your local Decatur County Extension Agent, or fill out the UGA Pasture Mealybug Survey at uga.questionpro.com/PMBupdates so researchers can track the pest and connect you with help.

• Practice farm biosecurity. Clean your equipment between fields. Change clothing and footwear when moving between farms. Limit vehicle traffic through pastures. Avoid moving livestock through affected areas and keep grazing records.

• Visit the UGA Pasture Mealybug Resource Hub at georgiaforages.caes.uga.edu/pasture-mealybug-resources.html for updated maps, ID guides, and the latest suppression research.

• Keep your lawn mowed. For residential and commercial property owners: short, well-maintained grass is far less hospitable to mealybugs than tall, unkempt vegetation.

• Share the word. Tell your farming neighbors, church members, and community group contacts. The more eyes watching for this pest, the better the chances of slowing its spread across Southwest Georgia.

• Support local farmers. Knowing that Georgia agriculture is under pressure, consider buying locally grown beef, produce, and hay from Decatur County and surrounding area farms whenever possible. Your purchases help sustain families who are working hard to protect Georgia's land and food supply.

Know the Signs: What to Look For

If you spot any of the following on your land, contact your local Extension Agent right away:

• Yellowing grass patches that turn purple or red

• Stunted or drought-stressed grass even after recent rainfall

• Poorly developed or shallow root systems

• Dieback beginning at the tips of older leaves

• White, fluffy, or mealy-looking spots near the base of grass plants or in the soil thatch layer
