Three new cases of West Nile have been reported in Bexar County by the Metropolitan Health District, bringing the total to 13 people with the virus.
The virus is high on the Alamo Heights council meeting agenda Monday night for an aggressive use of larvacides for fogging. Patrick Sullivan Alamo Heights Director of Public Works says they are using both and they just finished fogging last Wednesday.
Sullivan will be proposing the use of larvicides only.
“Fogging is the least affective process for dealing with mosquitoes. It doesn’t have any residual or long lasting benefits. It only kills the mosquitoes that are airborne at the time that the fogging actually takes place,” Sullivan said.
Sullivan says the fog kills mosquitoes that may be in the air at the time of spraying but the larvicides can go dormant until it gets wet again.
The Metropolitan Health district says they will continue their spraying until the end of mosquito season at the end of the month.
