If larvae are found, the inspectors will treat the water or remove the source. To schedule an inspector, please call the Office of Mosquito Control at 732-542-3630.”

In Keansburg, Holmdel and Hazlet, the Office of Mosquito Control will be applying Duet using Ultra Low Volume (ULV) sprayers mounted in the bed of a pick-up truck. A map of the areas to be treated and a fact sheet will be posted on the Office’s website visitimonmouth.com/mosquito under mosquito schedule and maps.

“Mid-July through September is the peak time for West Nile virus activity,” said Commissioner Susan M. Kiley, liaison to the Department of Health and Human Services. “When people are outdoors, they should take precautions such as using repellents or wearing long-sleeve shirts and long pants to avoid mosquito bites.
