Super Plugs are made of tough, chemical resistant polyethylene for long life while retaining its tight seal to prevent vapor escape. The geysering effect has always been a problem for the termite specialist. Super Plugs will prevent this from occurring in the many sensitive areas of a structure. Since liquids follow the path of least resistance, the next drilled hole may geyser pesticide. By using Super Plugs, the pesticide is forced to remain under the concrete, allowing a more thorough treatment, without the danger of liquid pesticides spilling in the structure or exposing the technician. Non-sealing plugs and even the existing sealing plugs will force up and out of the hole.
