NCDA&CS to treat gypsy moth infestation
Detailed treatment map available at

RALEIGH - The N.C. Department of Agriculture and Consumer Services will soon start treating for a gypsy moth infestation in Surry County, North Carolina. The treatment is scheduled for June 6. The area to be treated is:

  • Dobson area in Surry County.

“We have a total of one block and 1,231 acres to treat,” said Whitney Swink, NCDA&CS entomologist. “The treatment is scheduled to occur on June 6 adding a couple of days to cover possible delays.”

Prior to normal gypsy moth mating periods, low-altitude fixed-wing aircraft will disperse SPLAT Gypsy Moth-Organic infused with the naturally occurring gypsy moth pheromone.

The presence of the pheromone makes male gypsy moths unable to follow the natural pheromone scent trails released by the females. This decreases mating success and reduces the gypsy moth population. The pheromone is not harmful to humans, animals or plants, and it will not affect other insect species.

Gypsy moths feed on the leaves of more than 300 different species of trees and shrubs, predominantly oaks and hardwoods. When areas become heavily infested, trees may be completely stripped of foliage, leaving yard trees and entire forests more susceptible to attacks from other pests. Severe infestations often lead to tree death. Gypsy moth caterpillars can also pose public health concerns for people with respiratory problems. In areas with high-density gypsy moth populations, the caterpillar hairs and droppings may cause severe allergic reactions.

NCDA&CS has addressed spot introductions of the gypsy moth across North Carolina since the 1970s. The treatment will be done in cooperation with the U.S. Department of Agriculture’s Forest Service, Swink said.

A public hearing was held in February to discuss this infestation and receive input from residents about treatment options.
