What are the most common pool pests in Florida?

I live in North Central Florida. The most common pest in my pool is the predacious diving beetle. These little bast- ... buggers will actively chase you down and take a bite. It hurts but I don't think they're venomous. I read they can get up to an inch long but I've never seen one longer than a 1/4 inch. I spend the first 5 or 10 minutes in the pool searching for these beetles then scooping them up in the net and crushing them on the side of the pool.

I also frequently have backswimmer beetles in the pool as well but these generaly leave me alone unless I try to catch them. I caught one by hand once and he bit me hard. They have a long tube of a mouth they use to suck blood from their prey and he pierced my finger. I don't catch them by hand anymore. I just scoop them out with the net and send them on their way.

It is rare but not unheard of to find an alligator in your pool so always give a quick check before jumping in.
