SAN ANTONIO – Mosquito fogging is underway at Joint Base San Antonio – Fort Sam Houston, the latest local military installation to be treated again.
Mosquitoes there tested positive for West Nile Virus and leaders say no chances are being taken.
Crews will work until well after midnight using a truck-mounted fogging system to attack adult mosquitoes.
It’s the same insecticide used when crews go around with handheld devices. But with a truck, there's a wider target: 300 feet in each direction.
Crews started in the Salado Creek area Tuesday night, where there's a lot of standing water, and after midnight will fog around the housing areas.
There's a lot of ground to cover: 2,900 acres.
"It will take three nights: tonight through Thursday night,” JBSA spokesman Brent Boller says. “We'll continue to do this truck-mounted mosquito spraying. Then we'll re-evaluate in terms of positive test pools coming back and we may continue to do it as long as mosquito season lasts."
The insecticide is not believed to be harmful to humans and similar fogging is taking place at other local military installations.
