According to a press release from the City of Van Alstyne, the Grayson County Health Department has advised that one mosquito trap set at 245 W. Van Alstyne Parkway has tested positive for West Nile Virus (WNV).

To help protect against mosquito bites follow the four D's:

Drain - drain standing water;

Dress - wear long sleeves and long pants;

DEET - apply insect repellent with DEET;

Daily - all day every day.

Other ways to avoid mosquito bites include staying in air-conditioned areas or if leaving windows and doors open for air circulation purposes, ensure those windows and doors have intact screens in place, repairing any openings that may exist in those screens.

Spraying of the area will begin spraying Monday evening. Residents are advised to make sure their pets are put away or placed inside so as not to be exposed to the spraying. The spraying will take approximately three weeks to complete and will be done across the city in order to kill the infected population.
