How Can You Help?

To prevent the spread of fruit flies through infested fruits and vegetables, residents are urged not to move any fruits or vegetables from their property.  Fruits and vegetables may be consumed or processed (i.e. juiced, frozen, cooked, or ground in the garbage disposal) at the property of origin. If they are not consumed or processed, dispose of them by double-bagging them in plastic bags and putting the bags in the garbage bin for collection.

  • Never remove fresh produce from your property if you live in an infested area.
  • Cooperate with all regulation restrictions or rules that might be imposed.
  • Allow authorized agricultural workers access to your property to install and inspect insect-monitoring traps.
  • Know the regulations in your area.
  • If you see the Mediterranean Fruit Fly or infested fruit, report it to your State Plant Health Director as soon as possible.
