Types of Termites
There are over 2,000 species of termites, but they are generally categorized into three main types:
- Subterranean Termites: These are the most common and are found in every state except Alaska. They build their colonies underground.
- Drywood Termites: These termites live in the wood they consume and are often found in coastal, southern, and southwestern regions.
- Dampwood Termites: Preferring moist wood, these termites are less common and are typically found in the Pacific Coast and adjacent states.
Physical Appearance
Size and Color
Most termites range from 1/4 to 1/2 inch in length, though queens can grow much larger. Their coloring varies by species and caste:
- Workers: Soft-bodied, pale cream or white
- Soldiers: Similar to workers but with darker, hardened heads
- Reproductives (Alates): Dark brown to black
- Queens: Can reach several inches in length with a cream-colored, elongated abdomen
Body Structure
Unlike their common lookalike, the ant, termites have several distinctive features:
- Straight antennae (versus ants' elbowed antennae)
- Broad waist (versus ants' pinched waist)
- Equal-length wings in reproductive termites (versus ants' uneven wings)
Colony Structure and Behavior
Termites live in highly organized colonies with distinct castes:
| Caste | Primary Role | Appearance |
|---|---|---|
| Workers | Food gathering, nest maintenance | Small, white, wingless |
| Soldiers | Colony defense | Large heads, powerful mandibles |
| Reproductives | Colony expansion | Dark-colored, winged |
| Queen | Egg laying | Largest colony member |
"Swarming is a critical identifier of termite presence, typically occurring during warm, humid conditions after rainfall."
Signs of Infestation
Detecting a termite infestation early can save you from costly repairs. Look for these signs:
- Mud Tubes: Subterranean termites build mud tubes for protection and moisture as they travel between their colony and food source.
- Wood Damage: Termites consume wood from the inside out, leaving a thin veneer of wood or paint.
- Frass: Drywood termites leave behind small, pellet-like droppings known as frass.
- Swarmers: The presence of winged termites or discarded wings is a sign of an active infestation.
- Bubbling or uneven paint surfaces
Sound Indicators
Soldier termites make a distinctive clicking sound when disturbing the colony by:
Banging their heads against tunnel walls
Creating vibrations to alert others
Prevention and Control
To prevent termite infestations, consider these strategies:
- Maintain proper ventilation
- Keep wood away from soil contact
- Regular inspections by professionals
- Address moisture issues promptly
- Use treated wood in construction
- Fix leaks and ensure proper drainage around your home

Remember that proper identification is crucial for effective treatment. When in doubt, consult a licensed pest control professional who can properly identify the species and recommend appropriate treatment options.
