A subsurface pesticide injection system for use in combination with a structure having a footing formed in a base soil, a stem wall formed on the footing and defining a perimeter of the structure, a fill material disposed on the base soil within the perimeter of the stem wall, and a concrete slab formed on the fill material is provided. The concrete slab has openings extending therethrough. The subsurface pesticide injection and fluid extraction system comprising includes a tubular conduit disposed adjacent the foundation of the structure. The tubular conduit has a sidewall and a plurality of tortuous pores extending through the sidewall of the tubular conduit. A connector member is attached to one of the first and second ends of the tubular conduit and detachably connectable to a source of pressurized pesticide such that pesticide may be selectively injected into the fill material in an injection mode to form a chemical barrier against the infestation of pests into the structure through the openings of the concrete slab.
