2026 Atlantic County Department of Public Works Mosquito Q&A Sheet

Q. What types of mosquitoes do we have in Atlantic County?

A.   Of the 63 different species of mosquitoes found in the state of New Jersey, 40 of those have been found in Atlantic Countyexisting in a wide variety of habitats. Mosquitoes are found breeding in roadside ditches, flooded woodlands, freshwater swamps, storm water basins, coastal salt marshes, and just about any artificial container that will hold water for more than five days. Mosquito species that breed in our salt marshes are our major pest problem because of the large populations that can occur and because of their ability to travel large distances (over 20 miles) in search of a blood meal.
