Subterranean termites feed exclusively on
wood and wood products containing cellulose. Termites
have protozoa (microorganisms) in their intestines that provide
enzymes to digest cellulose. Although termites are soft-bodied
insects, their hard, saw-toothed jaws work like shears and
are able to bite off extremely small fragments of wood, a
piece at a time. Termites often infest buildings and damage
lumber, wood panels, flooring, sheet rock, wallpaper, plastics,
paper products and fabric made of plant fibers. The most serious
damage is the loss of structural strength. Other costly losses
include attacks on flooring, carpeting, artwork, books, clothing,
furniture and valuable papers. Subterranean termites do not
attack live trees.
An average subterranean termite colony can consume 5 grams
of wood per day, the equivalent of 2 1/3 linear feet of
a 2'x4' pine board annually. |
