If you’re spending time outdoors this summer, take a quick look before reaching into trees or shrubs. Venomous “asps,” also known as Southern flannel moth caterpillars, are active across North Texas and can deliver an intensely painful sting.
The fuzzy, teardrop-shaped caterpillars are often found on oak, pecan, elm, hackberry, and plum trees. Although they look soft, the hair-like covering hides venomous spines that can cause severe burning pain, a rash, swelling, and, in some cases, nausea, headaches, or chest pain.
If you’re stung, the Texas A&M AgriLife Extension recommends using adhesive tape to remove embedded spines, washing the area with soap and water, applying ice, and taking an oral antihistamine if needed. Seek immediate medical attention if you have trouble breathing or experience a severe reaction.
It’s a good reminder to teach children not to touch fuzzy caterpillars, no matter how harmless they appear.
