Systems to exterminate and control subterranean termites and other subterranean pests

A system to exterminate and control subterranean termites and other subterranean pests inhabiting a subterranean area surrounding or in close proximity to a structure having a perimeter near ground level, said system comprising:

• a. a plurality of first pipes each of which has a plurality of holes in its sidewall, said first pipes being disposed beneath ground level along the perimeter of the structure;
• b. a source of steam fluidly coupled to said first pipes;
• c. a plurality of temperature sensors each of which is disposed adjacent to one of said first pipes whereby said temperature sensors generate a temperature signals;
• and
• d. a controller electrically coupled to said temperature sensors for regulating pressure and/or temperature of said source of steam in response to said temperature signals.

A system to exterminate and control subterranean termites and other subterranean pests inhabiting a subterranean area surrounding or in close proximity to a structure which is mounted on a concrete slab at ground level, said system comprising:

• a. a plurality of first pipes each of which has a plurality of holes in its sidewall, said first pipes being disposed beneath the concrete slab;
• b. a source of steam fluidly coupled to said first pipes;
• c. a plurality of second pipes each of which has a plurality of holes in its sidewall, said second pipes being disposed beneath ground level along the perimeter of the structure;
• d. a plurality of temperature sensors each of which is disposed adjacent to one of said second pipes whereby said temperature sensors generate temperature signals;
• and
• e. a temperature display electrically coupled to said temperature sensors in response to said temperature signals.
