Termite pest control > Nonsubterranean termites
The nonsubterranean termites which are injurious attack wood directly; but, instead of following the grain continuously, they excavate through it longitudinal chambers of limited length.
The sexual adults, after they have lost their wings, and the young or nymphs, are the destructive forms. Their pellets of excrement are regularly. impressed, and sometimes completely fill or block up the burrows in a compact mass; they are often expelled as dry droppings from the infested wood.
These termites are destructive to the woodwork and furniture in buildings, as well as to living trees. Apparently they can exist without the great amount of moisture necessary to the life of termites which are subterranean in habit.
