Matters needing attention when a caterpillar on a walnut tree stung
After being stung by a worm on a walnut tree, you can grind it with a Chinese medicine throat pill and apply water to the affected area. If dermatitis occurs, the venom should be sucked out and pricked, and then coated with 5%10% ammonia water or 5%10% sodium bicarbonate solution. Have fever, joint swelling and pain and other systemic symptoms, may produce allergies should be treated in the hospital.
After being stung by insects on walnut trees, the most important thing is to pull out the burrs of pests stuck in the skin. Because the burr is very small, you must use sterilized tweezers or medical adhesive plaster to pull out all the burr parts at the wound when pulling out the thorn. Never pull it out by hand, not only the wound may be infected with bacteria, but also it is difficult to operate.
