What Are Termites ?

Termites are wood-eating insects that cause significant structural damage to homes and buildings. These social insects live in colonies and feed on cellulose-based materials like wood, paper, and cardboard. They require moisture to survive and create extensive tunnel systems to move between their nests and food sources. 

Termites have complex social structures with specialized castes including workers, soldiers, and reproductive members that maintain colony functions.

Types of Termites

• Subterranean Termites: Live underground and enter homes through soil contact points. They require constant moisture and create mud tubes to travel between their colonies and food sources. These termites are responsible for most structural damage in residential properties and require soil-based treatment approaches.
• Drywood Termites: Infest dry wood directly and don’t require soil contact. They create galleries inside wooden structures and are harder to detect than subterranean termites. These termites can survive with minimal moisture and often require localized treatment methods for effective control.
• Dampwood Termites: Prefer moist, decaying wood and are commonly found in areas with high humidity. They typically infest logs, stumps, and wooden structures with moisture problems, making moisture control essential for prevention.
• Formosan Termites: An aggressive subterranean species that builds large colonies and causes rapid structural damage. They create aerial colonies in walls and attics, requiring specialized treatment approaches including foam applications.
