Drywood termites have a low moisture requirement and can tolerate dry conditions for prolonged periods. They remain entirely above ground and do not connect their nests to the soil. Piles of their fecal pellets/droppings, which are distinctive in appearance, may be a clue to their presence. The fecal pellets are elongate (about 3/100 inch long) with rounded ends and have six flattened or roundly depressed surfaces separated by six longitudinal ridges. They vary considerably in color, but appear granular and salt and pepperlike in color and appearance. Winged adults of western drywood termites (Incisitermes minor) are dark brown with smoky black wings and have areddish brown head and thorax; wing veins are black. These insects are noticeably larger than subterranean termites.
Drywood Termites, are Sometimes they have to tent/fumigate the entire building. Depending on the physical shape of the structure, this can be quite difficult. The likely candidate for this is the drywood termite. Drywood termites do not (naturally) survive in the temperate zone. Drywoodtermites can, however, be imported from their native habitats, often in furniture and other wooden or decorative items. (section “1″ categorypest / Structural Pest Control).
The western subterraneantermite, is the most destructive termite (section “1″ category pest / Structural Pest Control) found in California. Reproductive winged forms of subterranean termites are dark brown to brownish black, with brownish gray wings.
Subterranean Termites are smaller than Drywood termites, approximately one-fourth inch long. They create colonies in the soiland require moisture to survive. Unlike Drywood Termites, they do require a direct connection to soil. They build tubes up the side of concrete foundations or straight out of the ground, making highway tunnels for traveling to their food source and back
Subterranean termite is the most destructive species of subterranean termites. Another destructive species in this group, theFormosan subterranean termite, Coptotermes formosanus, is now in California but restricted to a small area near San Diego and Los Angeles. Unlike the western subterranean termite, Formosan subterranean termites swarm at dusk and are attracted to lights.
Subterranean termites require moist environments. To satisfy this need, they usually nest in or near the soil and maintain some connection with the soil through tunnels in wood or through shelter tubes they construct. These shelter tubes are made of soil with bits of wood or even plasterboard (drywall). Much of the damage they cause occurs in foundation and structural support wood. Because of the moisture requirements of subterranean termites, they are often found in wood that has wood rot.
Carpenter Ants don’t eat wood, but they sure like to make it their home. They bore into wood framing and even wood cabinets to make their nests.
They do cause structural damage but are usually noticed by home owners during swarming season when huge black flying ants are all over the place. They are about 3/4 of an inch in length…. These ants seldom tunnel into dry, sound wood, but they may excavate moist, rotting woods to make the nests. Rarely will the expansion of a nest into a building’s wooden timbers cause structural damage (section 1 category pest / Structural Pest Control).
Powder Post Beetles are found in a variety of wood products. They infest everything from wicker baskets tohardwood floorsand pianos. They are usually detected by seeing very fine saw dust or little holes in wood surfaces. The holes are the openings through which the adult beetles emerge.
Powderpost beetles prefer the sapwood of oak and other hardwoods and many of the insects will continue to breed in an infested piece of wood for generations. This practice can result in an ultimate destruction of the wood.
Carpenter Bees are large black bees that bore holes into wood to make their nest to lay eggs. They are usually found in fences and trees. The holes are about 1/2 of an inch in diameter and about 2 inches deep it makes a damage on the wood
Dry rot (section “1″ category: Structural Wood Destroying Organism) , is the cause of sever timber decay in buildings. Described as a brown rot, it often occurs in damp timber which is un vented space andin contact with, or embedded in, wet brickwork or masonry.
The fungus is sensitive to high temperatures, air movement and rapid drying. Exposed timbers and timbers where there is good ventilation are rarely affected. Affected timber takes on a very dull brown colour, mostly developing deep cracks along and across the grain. The timber loses weight and will crumble between the fingers. The dry rot fruit body is often found on a timber to wall joint, this can some times be a reaction to unfavourable conditions. The body is quite tough and fleshy tofeel, and develops a pancake like shape. The centre is a yellow ochre when it is young and this develops to a deep rust colour when it is older. The deepening in colour is a result of the fine, brown spores it produces which are generally gathered in a dust below the body. The edges of the fruit body will be white or grey. The fruit body may be the first visible sign of dry rot out break
