The State of Connecticut Mosquito Management Program announced Tuesday that mosquitoes trapped in Milford on June 29 tested positive for West Nile virus.

Officials say the mosquitoes are the first West Nile virus positive mosquitoes of the season to be identified by the Connecticut Agricultural Experiment Station.

In 2025, West Nile was detected in 230 mosquito samples from over 30 towns. Six residents were hospitalized with the disease, including one person who died.

Officials say most people infected are bitten from July through September.

Nearly 80% of people will not develop any symptoms, which include fever, headache, body aches, joint pain and rash.

The Connecticut Agricultural Experiment Station says residents can cut their risk of mosquito bites — and mosquito‑borne viruses — by following the Four Ds.

Dress in long sleeves and pants in mosquito‑heavy areas. Defend yourself with EPA‑registered repellent and make sure window screens and doors are in good shape. Dusk to dawn is when mosquitoes are most active, so take extra care during those hours. Dump standing water around your home every week to prevent breeding.
