West Nile is still showing up in North Texas mosquito samples, and a few cities have been doing overnight sprays when traps come back positive.
A positive mosquito pool is a real signal, but it is not the same thing as a human outbreak on your street. Frisco planned overnight ground spraying for eight neighborhoods on the nights of Sept 26 and 27, weather permitting: Fairfield Estates, Lakes of Preston Vineyards, Parkside Estates, Plantation Estates, Preston Lakes, Preston Vineyards North, Shepherds Hill, and Stonebryck Manor. Dallas and Arlington also ran targeted sprays recently after positive samples. Denton County has reported five confirmed human West Nile cases so far this year.
What actually helps at home:
Dump standing water (buckets, birdbaths, gutters, toys, plant saucers)
Be careful at dusk and dawn
Use an EPA-registered repellent when you are outside
City spray helps in the mapped zones. It does not replace taking care of your own yard. If mosquitoes are wrecking your patio, Preferred Pest Management does mosquito control for North Texas homes, including barrier treatments and In2Care station options.
