Gardening in the sunshine state is a relatively benign affair. However, it’s important to watch out for critters that can do some damage. They may not affect plants, but the venom of the “puss caterpillar” (Southern flannel moth) is harmful to humans.

Rarely are these caterpillars deadly, although it’s good practice to keep your distance. The inch-long bug is covered in furry-like hair which hide toxic spines. These can stick to your skin. The sting can cause itching, burning, rashes, lesions and swelling and on numerous spots on the body.

Experts say, according to WFLA, if you are stung to get the “spines out of your skin as soon as possible using cellophane tape. Ice packs, oral antihistamine, and hydrocortisone cream can also be used to help with the pain.”

Puss caterpillars are not only located in Florida, but can be found in between here and New Jersey, or as far west as Texas. In Florida, expect to see them in the fall and spring. They usually are found in oak and elm trees.

However, Lyle Buss, an entomologist from the University of Florida’s Insect Identification Lab, told Newsweek that “puss caterpillars are generally pretty common in Florida, although I haven’t seen any this year myself.”
