The most common pest in Florida is the cockroach, particularly the American cockroach, often called the Palmetto bug, and the German cockroach. Florida’s warm and humid climate also supports large populations of ants, termites, mosquitoes, and spiders. Among these, subterranean termites and fire ants are particularly destructive, while mosquitoes are a significant health concern due to their ability to spread diseases like dengue and West Nile virus.
