If you live in Florida, or visit here, you know that the Sunshine State is home to many bugs. Thousands of species of insects, spiders, mites and other creepy-crawly arthropods roam the state — some beneficial to people, some potentially harmful to people, some neither, some both.
You may have a few questions about Florida’s bugs. That’s why we’re here.
UF/IFAS entomology experts want to make sure you get the facts about Florida’s bugs, so we’re providing this FAQ backed by science-based answers.
If you have questions that aren’t addressed in the current version of the FAQ, let us know by writing to sfyl@ifas.ufl.edu. Many of the questions submitted will be featured on the UF/IFAS Facebook and Twitter pages during UF’s annual Bug Week celebration every May. And the online FAQ will continue to grow as new material arrives.
