SAN ANTONIO – Bexar County Public Works confirmed another mosquito has tested positive for the West Nile Virus in Northwest Bexar County.

This is the third mosquito found within the last 30 days, said BCPW.

All positive mosquitos were located in the northwestern part of the county and crews have been aggressively treating the area.

BCPW ask that residents in the area protect themselves against West Nile and other mosquito-borne disease activity including the Zika virus, West Nile disease, and Chikungunya.

The department said to drain out any standing water in yards as mosquitos can breed in as little water as a capful. Check flower pots and their trays, pet water dishes, toys and bird feeders. The department said if there are any pools, reflecting ponds, water play stations or similar water areas to make sure the water has been chlorinated or treated.

BCPW encourages people to use mosquito repellent when outside and to take basic precautions to help limit the exposure.
