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.
Hydrochloric acid is prepared by dissolving hydrogen chloride in water. Hydrogen chloride can be generated in many ways, and thus several precursors to hydrochloric acid exist. The large-scale production of hydrochloric acid is almost always integrated with the industrial scale production of other chemicals.
