Pests to know in Gainesville
Termites in Gainesville
- UF/IFAS reports that two native subterranean termites, Reticulitermes flavipes and Reticulitermes virginicus, occur throughout Florida, which includes the Gainesville area.[7]
- University of Florida researchers say Florida homes face two main termite types: subterranean termites that attack from the soil up, and drywood termites living inside dry structural wood.[8]
Invasive species reported here
A UF study found the invasive Formosan subterranean termite established in most large Florida cities and judged it highly likely to reach the entire state before 2050.[10]
Pests local experts flag
- Gainesville's city mosquito program stocks mosquitofish (Gambusia holbrooki) and uses biological larvicides to cut down mosquito larvae before they become biting adults.[4]
- City of Gainesville mosquito technicians monitor and treat over 500 breeding sites, including retention ponds, roadside ditches and low-lying ground.[5]
Climate
Central Gainesville (ZIP 32601) is in USDA plant hardiness zone 9a, where the average coldest winter night is 20 to 25°F.[11]
Public agencies that handle pests
- DOH-Alachua tracks mosquito-borne viruses in the county using sentinel chickens and mosquito testing, alongside human, horse and wild bird disease reports.[1]
- Alachua County health officials name raccoons and bats as Florida's main wildlife rabies sources; possible exposures can be reported to DOH-Alachua or Alachua County Animal Services.[2]
- Outdoor cats are the domestic animal most often found with rabies in Florida, which is why state law requires rabies shots for dogs, cats and ferrets.[2]
- Mosquito work around Gainesville is shared: DOH-Alachua coordinates with Alachua County plus the Gainesville, Alachua and Newberry mosquito control programs on surveillance and treatment.[3]
Hiring a licensed company
Florida requires every structural pest control business location to hold an FDACS license and employ a full-time certified operator in charge, certified in each category it offers, including termite work.[9]
