termites. Insects
that superficially resemble ants in size, general appearance,
and habit of living in colonies; hence, they are frequently called
"white ants"; subterranean termites establish themselves
in buildings not by being carried in with lumber, but by entering
from ground nests after the building has been constructed; if unmolested,
they eat out the woodwork, leaving a shell of sound wood to conceal
their activities, and damage may proceed so far as to cause collapse
of parts of a structure before discovery; there are about 56 species
of termites known in the United States; but the two major ones,
classified by the manner in which they attack wood, are ground inhabiting
or subterranean termites (the most common) and dry wood termites,
which are found almost exclusively along the extreme southern border
and the Gulf of Mexico in the United States
