WEST TRENTON - Following a wet spring and now sizzling temperatures, mosquitoes are breeding across New Jersey.

A line of defense is set up to ward off the blood-sucking insects. They're known as copepods. Copepods are tiny freshwater crustaceans that are also the natural enemy of mosquitoes.

The New Jersey Department of Agriculture is raising copepods by the thousands in a lab in West Trenton. The copepods are being given to local mosquito control offices, which set them free in standing water where mosquitoes breed.
