* Termites: sometimes incorrectly called white ants, are a group of social insects Termites mostly feed on dead plant material, generally in the form of wood, leaf litter, or soil and about 10% of the 4,000 odd species are economically significant as pests that can cause serious structural damage to buildings, crops or plantation forests. Termites are major derivers, particularly in the subtropical and tropical regions, and their recycling of wood and other plant matter is of considerable ecological importance.
As social insects, termites live in colonies that, at maturity, number from several hundred to several million individuals. They are a prime example of decentralized, self-organized systems using swarm intelligence and use this cooperation to exploit food sources and environments that could not be available to any single insect acting alone. A typical colony contains nymphs (semi-mature young), workers, soldiers, and reproductive individuals of both genders, sometimes containing several egg-laying queens .

* I don't treat for termites, this is just for general info. But I can refer you to someone that does treat for termites. At a fair price.

Carpenter bees, are so named because they excavate galleries in wood to create nest sites. They do not consume wood. Rather, they feed on pollen and nectar. Carpenter bees are important pollinators of flowers
Identification
Carpenter bees are large and robust. Is three-fourths to one-inch long, black, with a metallic sheen. Carpenter bees somewhat resemble bumble bees, except bumble bees have dense yellow hairs on the abdomen and large pollen baskets on the hind legs. Various species of bumble bees and carpenter bees are similar in size. Bumble bees typically nest in the ground whereas carpenter bees nest in wood.
 in an exposed or unexposed location. This hole is slightly less than 1/2-inch wide, approximately the diameter of her body. She bores into the wood perpendicular to the grain for one to two inches then makes a right angle turn (~90°) and excavates along the wood grain for four to six inches to create a gallery (tunnel). She excavates the gallery at the rate of about one inch in six days.
The carpenter bee entrance hole in wood may not necessarily be in an exposed area. For example, the inner lip of fascia boards is a common site of attack. Nail holes, exposed saw cuts, and unpainted wood are attractive sites for the bees to start their excavations.

WOOD DESTROYING BUGS AND INSECTS

They usually nest outside in moist wood or partially decayed wood.
Carpenter ants prefer to hollow out their nests in softened wood. These galleries are clean and have a sandpaper appearance. Wood that has been damaged by carpenter ants contains no mud-like material, as is the case with termites. Carpenter ants nests are commonly found in such places as moist, hollow, spaces like the wall void behind dishwashers. Carpenter ants nests are usually found in areas where water leakage could occur, such as around bathtubs, sinks, roof leaks, poorly flashed chimneys, or poorly sealed windows or door frames.
