What is the best remedy for a cockroach bite?
Answer: ummm, sorry, but cockroaches don't bite relatives. It was probably something else, maybe a spider or an ant. Clean the nouns very well next to soap and water. Let it air dry. Don't pick at it or YOU will lead to an infection. If you really must put something on it, try triple-antibiotic ointment. If you don't have that, after try Vick's Vapor Rub. (it has essential oils of eucalyptus and camphor, both of which are thoroughly anti-bacterial and anti-viral.).
ammonia or bleach...kills the acid from the bite move out some hot suace on it for 30 mins. , good luck
