Bees and Wasps: What to know and when to be concerned
There has been a lot of publicity surrounding the Asian giant hornet in the United States, but as of today, the hornets (Vespa mandarinia) have only been found in Washington state. Of course, insects can be transported across state lines and it is always a good idea to watch and observe insects you find in your landscape. We do want you to be aware of the bees and wasps found in central Florida and how many are beneficial insects, meaning they help control plant pests in your yard by doing things like feeding upon them. It is important to identify an insect before you eradicate it, and your local UF/IFAS Extension Service can help you with that.
First, it is important that we don’t confuse one of our beneficial wasps for the Asian giant hornet. In particular, the cicada killer wasp is one of the largest wasps in Florida and doesn’t look like it would be a desirable insect. The cicada killer wasp is actually a beneficial insect that constructs small mounds in the soil as it is a ground-nesting insect. This large wasp can look scary, and it the most common local wasp that is currently being mistaken for the Asian giant hornet. This blog post has some great photos and information on the cicada killer wasp.
Additionally, there are other bees and wasps doing good work in your landscape. Mason bees, miner bees, sweat bees, and honeybees all provide valuable pollination services. Parasitic wasps are also beneficial. They are often very small, and not easily confused with large hornets.
Finally, there are hornets and yellowjackets, which can be found throughout Florida (and beyond). While they do provide valuable services consuming pest insects, nests near homes are not wanted and can be problematic. Be cautious when removing or call a professional.
Just remember, it is always important to identify and insect before deciding to eradicate it.
