Which county in Florida was historically known as Mosquito County?

Orange County in Florida was historically known as Mosquito County. This name was primarily due to the prevalence of mosquitoes in the region, especially during the early periods of settlement when the area was largely undeveloped and had abundant swamps and wetlands providing ideal breeding conditions for these insects.

The name change occurred in 1845 when the county was renamed to Orange County, reflecting the growth of the citrus industry and a desire to associate the region with something more positive than its former moniker. This change symbolized a shift in the county's identity and development, as the citrus industry played a significant role in shaping the local economy and attracting new residents.

The other counties mentioned may have had issues with mosquitoes, given Florida’s overall climate, but they were not historically referred to as Mosquito County.
