Caulk or seal behind baseboards and in cracks and crevices where centipedes like to hide. Place a dehumidifier in damp areas to sufficiently dry the air. Structural repairs may be necessary to the home and/or yard if a dehumidifier does not keep a room sufficiently dry.
Hydrogen chloride is a colorless to slightly yellow gas with a sharp, irritating odor. It forms a dense white vapor when it comes in contact with air. When hydrogen chloride dissolves in water, it forms hydrochloric acid also known as muriatic acid.
While chlorine gas is only moderately soluble in water, hydrochloric acid is highly soluble. The predominant targets of the acid are the epithelia of the ocular conjunctivae and upper respiratory mucous membranes. Hypochlorous acid is also highly water soluble with an injury pattern similar to hydrochloric acid.
