WDI (Termite) Inspection
Serving Western MA & CT

WDI Inspection, also known as Wood Destroying Insect Inspection, is an important part of any home inspection. This inspection is used to identify wood-destroying organisms (termites, powder post beetles, carpenter ants, and carpenter bees) that may be present in the home. During the inspection, a professional will look for visible signs of damage and infestation, as well as any conducive conditions that could lead to an infestation. The purpose of this inspection is to detect any problems early and to provide the homeowner with the necessary information to make an informed decision about their home.

Wood Destroying Insect Life Cycles

Subterranean Termites: A type of soil-dwelling insect, have a fascinating life cycle that begins with swarming. During swarming, winged male and female reproductives leave their existing colony to find mates and establish new colonies. After mating, they shed their wings and the female becomes the queen while the male becomes the king. The queens primary role is to lay eggs, which hatch into nymphs. The nymphs develop into different castes, including workers, soldiers, and reproductives, each with specific responsibilities within the colony. Workers are responsible for foraging, feeding, and maintaining the colony, while soldiers defend it against threats. Subterranean termites have a significant impact on building structures, particularly the wood components closest to the soil. They feed on wood, causing severe damage that can compromise the structural integrity of a building. If left unchecked, termite attacks can lead to sagging walls, wood decay, and other forms of building deterioration. Structures with wood in direct contact with the soil provide an ideal environment for termites, offering a constant food source and a favorable climate. Therefore, it is crucial to implement effective termite control measures to protect buildings from these destructive pests.

Carpenter Ants, unlike termites, are wood-damaging insects that do not consume wood for sustenance but excavate galleries within it to create nests. They have a similar life cycle, beginning with winged reproductive ants swarming to establish new colonies. After mating, the female becomes the queen, while the males role ends. The queen lays eggs that hatch into larvae, which then go through developmental stages to become workers, soldiers, or future reproductives. Carpenter ants can have a significant impact on building structures by excavating galleries in wood, potentially causing structural damage over time. Its important to address carpenter ant infestations promptly to prevent further harm to the integrity of the affected wooden components.

Powder Post Beetles are wood-boring insects that can have a detrimental impact on building structures. Their life cycle begins with eggs laid in cracks or crevices of wood. Once the eggs hatch, the larvae tunnel into the wood, feeding on its cellulose content. As they grow, they create narrow, meandering tunnels that can weaken the wood structure. The larvae then undergo a pupal stage before emerging as adult beetles. These adult beetles have a short lifespan focused on mating and laying eggs in new wood sources. The damage caused by powder post beetles is characterized by small, powdery exit holes on the wood surface and the presence of frass (wood powder) near infested areas.

Carpenter Bees are wood-boring insects that can impact building structures. Their life cycle begins with female bees excavating tunnels in wood to create nesting sites. These tunnels can extend several feet into the wood, causing structural damage over time. After creating the tunnels, the female carpenter bee lays eggs within individual cells, providing provisions for the developing larvae. The larvae feed on the provisions, growing and eventually pupating. Adult bees emerge from the pupae and repeat the cycle by mating and establishing new nests. The damage caused by carpenter bees is characterized by round entry holes on wooden surfaces and the accumulation of sawdust-like frass near nesting sites.
