Termites are the most destructive pests found in homes and buildings. Their well-organized colonies are constantly on the hunt of new food sources, and once a reliable source is found they will never stop to rest or sleep.
They are known for eating wood but, in fact they will feed on anything that contains cellulose, including paper, drywall backer, carpet-backing, boxes, books, furniture, etcetera.
Once they have penetrated the structure ( your home or a building ), they work from the inside out. A colony may feed on your home for 3-5 years before there are any visible signs of damage.
Subterranean termites usually invade a structure from the soil along the foundation. They commonly enter through cracks in the slab, utility conduits, expansion joints, and plumbing connections.
When treating houses or other buildings, the perimeter of the foundation is trenched and drilled, then treated with termiticide. The goal of the treatment is to put a chemical shield between the termites in the soil and the structure above. The chemical shield can also affect those termites inside a building by preventing their successful return to the soil. In many cases, these termites will die of dehydration.
