Invasive Kudzu Bug Found Throughout State

Soybean growers warned to monitor for new pest

The kudzu bug.

ANNAPOLIS, MD – The kudzu bug, an invasive species from Asia, has been found in Anne Arundel, Calvert, Carroll, Charles, Dorchester, Montgomery, Prince George’s, Saint Mary’s, and Talbot counties. The Maryland Department of Agriculture is alerting soybean growers—especially organic soybean growers—to watch for this pest. Kudzu bugs can reduce yields, but can be controlled with appropriate pesticides.

“Kudzu bugs are invasive species that can have a significant impact on crop yields,” said Agriculture Secretary Joe Bartenfelder. “It is very important that farmers are aware of this insect and plan accordingly. Luckily, the kudzu bug is easily controlled with proper pest management planning.”

The kudzu bug typically feeds on kudzu vines and then may migrate to soybeans and other types of available beans. Excessive kudzu bug feeding can reduce soybean yields by reducing pods per plant, reducing beans per pod, and/or reducing seed size. In Maryland, the pests have mostly been collected on kudzu, however, some have been found on soybeans in Dorchester County and could spread to other counties.

The bug can also be a nuisance for homeowners, similar to the brown marmorated stinkbug. When crushed, the kudzu bug can stain surfaces in the home, cause skin irritation and smell bad. The worst time for kudzu bugs and homeowners are early spring and fall. Tips for homeowners on how to keep the bug out can be found here. Homeowners who think they have an infestation should contact a licensed pest control company. (Make sure you are dealing with a licensed professional by checking the department’s database)

To report a sighting or collected sample of kudzu bugs, contact the department’s Plant Protection and Weed Management section at 410-841-5920.
