10 Most Wanted Foreign Pests

  1. Mediterranean Fruit Fly
    Maggots destroy over 250 kinds of fruit, nuts and vegetables. Increases pesticide use.
  1. Melon Fly
    Devastates melons, squashes, tomatoes and other crops. Strong flier and breeds rapidly.
  1. Mexican Fruit Fly
    This fly's maggots ruin citrus, avocados, stone fruits and apples. Fruit must be fumigated to enter United States.
  1. Oriental Fruit Fly
    As bad as #1 and as strong as #2, an effective lure allows us to keep this fly from the top of the list.
  1. Hibiscus Mealybug
    Invading from the south, this pest has infested Imperial County, feeding on cotton, melons and other crops.
  1. Red Imported Fire Ant
    Infesting the South and portions of the Midwest, this ant's painful sting makes outdoor activity less pleasant. Kills ground-nesting birds and other young animals. A vicious predator.
  1. Gypsy Moth
    Defoliates broadleaf trees and damages conifers. Ruins forests and ornamental trees. Established in the Northeast states, North Carolina, Ohio, Indiana, Michigan, Wisconsin, Virginia, Maryland and West Virginia.
  1. Japanese Beetle
    Feeds on deciduous fruits, shade trees, flowers, vegetables and turf. Infests the US east of the Mississippi River.
  1. Hydrilla
    This weed grows rapidly, clogging waterways and irrigation channels. Fouls recreational lakes. Has caused problems in Florida. Local infestations in California have been eradicated.
  1. Burrowing Nematode
    This microscopic worm pierces roots of citrus and many ornamentals. Insidiously weakens the plants but doesn't kill it.
  1. Zebra Mussel
    A bonus pest for the list. This prolific invader attaches to boats, docks, rocks and water intakes. Very hard to kill. Survives in fresh and salt water. Has established itself in the Great Lakes, Mississippi River and other midwest and eastern U.S. rivers.
