Texas Asp, A Cute, Cuddly Caterpillar to Avoid

The Texas Asp is something to be aware of, a cute, snugly, furry caterpillar that only needs to be touched in order to get a nasty sting. The caterpillar may look furry but this hides sharp, tiny spines that can stick into your skin.

The Texas Asp Sting

The sting delivers a severe burst of burning, radiating pain. This radiating pain does not occur with other insect stings so is a clear sign that you have been stung by an Asp. It can feel like a bee sting but worse, people have also compared it to a scorpion sting or a jellyfish sting. The pain rapidly escalates and can even make your bones hurt. The sting can also result in a sudden loss of blood pressure, seizures and vomiting. Contact with the asp caterpillar can be fatal to anyone allergic to insect venom as it can send you into anaphylactic shock.

Ice packs can be used to assist in reducing the pain and swelling. Antihistamines such as Cortizone 10, Claritin or Benadryl can also help with any itching or swelling. Call for medical assistance if there is any fever, swelling of the throat or abdominal pain.
