Centipedes have long, flattened, and segmented bodies. Each segment has one pair of legs. Centipedes feed upon small creatures such as insects. They grasp and kill their prey by injecting venom. The bites of a centipede may cause redness, itching, swelling and some pain around the bite site. Some people, especially small children, may be allergic to the venom. Millipedes have two pairs of legs per segment and have cylindrical bodies. Millipedes do not bite, but they have glands on their bodies that can secrete a brown or white liquid that smells like iodine. If a millipede is handled or crushed, this liquid can cause redness, burning, rashes and eye irritation. First aid for centipede bites Wash the bite site with soap and water. Wrap a few ice cubes in a towel and apply on the area for 10-15 minutes to stop the pain and swelling. To prevent frostbite, do not apply ice directly on the sting area. If there is eye irritation, rinse the eye under gently running cool water for at least 15 minutes. Prevent run-off water from entering the unaffected eye.
