There are about 1.900 species of termites found in many

areas of the world, but most commonly in tropical rain

forests. Besides the termites that occur naturally in a given

area, many species have been transported accidentally by

man from their native habitats to new parts of the world.

They are transported in wooden articles such as shipping

crates, boat timbers, lumber and the furniture.

Termites are actually important to the ecology because

they help convert plant cellulose into substances that can

be recycled into the ecosystem to support new growth. But

termites are also very destructive because they feed upon

and damage wooden objects and crops. Termites that are

transported from other areas are even more dangerous

because they are not as able to eat the trees that grow in

their new environment . Therefore, they live in and eat

man-made wooden structure and crops.

Subterranean termites depend on contact with moisture in

the soil and generally reach the wood in man-made

structures through contact with the ground. The ground

below the foundations of new homes is frequently pretreated

with an insecticide to prevent entry by these termites.
