Although Florida is their main territory, puss caterpillars have been spotted in other areas of the United States.

September to November are particularly important months when encountering them becomes more likely.

Keep a lookout for these toxic critters lurking around during this time.

Spring Season: A Reappearance

Though they may appear harmless, they originate from dangerous caterpillars.

You'll find these creatures often from May to November, especially on oak and citrus trees, when they produce multiple generations.
