What's the best treatment to get rid of centipede sting?

Symptomatic relief. Centipedes have a painful bite and may cause swelling. The biggest concern is secondary infection, so wash the area with soap and water and watch carefully for signs of infection(pus, expanding redness).Hot compress may help reduce the pain, or an ice pack to relieve swelling. Over the counter pain relievers can be used as well as Hydrocortisone cream for itching.
