Regularly scheduled treatments will begin an hour before sunset and/or one hour after sunrise.

Pets and livestock

Residents are also reminded to have outdoor animals vaccinated against mosquito-borne disease. Horses should be vaccinated against Eastern Equine Encephalitis. Although West Nile and EEE viruses can occur throughout the year, peak season is August, September and October.

Dog owners are also reminded to have pets treated for heartworms since certain mosquitoes present in Okaloosa County can carry the disease.

Bees

The Florida Department of Agriculture and Consumer Services maintains a registry of beekeepers in the state. Florida law requires all keepers—agricultural or residential—to register their apiaries with the state.
