Prevent the Bite

The Mosquito Control Division of Harris County Health has enhanced its security procedures for our nighttime spray truck operations and storage facility.

All ULV spray trucks are constantly monitored via radio with communication codes to ensure that only authorized personnel operate our spray trucks. Each ULV spray truck is visually inspected and inventoried daily for signs of tampering. When our ULV spray trucks are not in use, essential components needed to operate the spray unit are removed. The spray unit will not function without these components. These components are stored in a secure area that is monitored by the security section of Facilities and Property Management of Harris County.

The Mosquito Control Division continues to evaluate these security procedures and works closely with law enforcement when necessary.
