Executive order extends to Oct. 29

Hillsborough County, Fla. (Oct. 22, 2026) – Hillsborough County Administrator Bonnie Wise has signed an executive order extending the state of local emergency under authority granted by the County’s Emergency Management Ordinance and Chapter 252, Florida Statutes.  

The state of local emergency now extends to Oct. 29 as the County works to control the mosquito population and protect residents from dengue fever – a mosquito-borne disease.

A state of local emergency can be in effect for only seven days, unless rescinded or extended. The emergency declaration gives the County Administrator and emergency managers the ability to quickly take certain actions to ensure the health, safety, and welfare of the community, and provides a path for reimbursement of certain expenses.

Mosquito Management crews are increasing treatments by air and ground because the County’s mosquito surveillance in many neighborhoods is showing dengue virus activity in the mosquito population. The County is working closely with the Florida Department of Health in Hillsborough County for education and treatment in the impacted areas.

Hillsborough County is urging residents across the County to take action to protect themselves from mosquitoes. Residents are encouraged to look for and eliminate standing water on their property after recent heavy rains. Sign up to be notified of where localized aerial treatments are occurring in each neighborhood. Hillsborough County also maintains an online resource, including FAQs, for residents to view where treatments are occurring.

Mosquito control services are funded in part by Hillsborough County property tax dollars. For information, contact Hillsborough County Mosquito Management Services at (813) 635-5400.
