Can a caterpillar bit make you sick?

Some caterpillars, such as the puss caterpillar and the saddleback caterpillar, have venomous spines that can cause a painful sting. The venom is not typically life-threatening, but it can cause symptoms such as swelling, itching, redness, and pain. In some cases, the sting may also cause nausea, vomiting, and dizziness. If you are stung by a caterpillar, it is important to wash the affected area with soap and water and apply a cold compress. You may also want to take an over-the-counter pain reliever such as ibuprofen or acetaminophen. If the symptoms are severe, you may need to seek medical attention.
