The first visible sign of a termite infestation is the presence of mud tubes (also called shelter tubes). These are small, pencil-width tunnels made of soil and saliva, often found on walls, foundations, or crawl spaces.

Why Mud Tubes Matter

• They protect termites from predators and dry air as they travel from their nest to a food source (usually your home’s wood).

• They’re a strong indicator of subterranean termite activity, the most destructive type of termite.

If you spot these tubes, especially near the base of your home, it’s time to take immediate action.

Other Early Warning Signs of Termites

While mud tubes are a primary sign, there are other indicators you might notice in the early stages of an infestation…

Swarming Termites or Discarded Wings

In spring or after rainfall, you may see flying termites (called swarmers) or find piles of shed wings near windows, doors, or light fixtures.

What it means – A mature colony is trying to expand & start a new one nearby.

Hollow-Sounding Wood

If you tap on walls, baseboards, or floors and they sound hollow or papery, termites may be eating the wood from the inside out.

Tiny Holes or Pinholes in Drywall

Termites sometimes create small exit holes in walls, often mistaken for nail holes or general wear & tear.

Bubbling or Peeling Paint

This can resemble water damage but may be due to moisture buildup caused by termites tunneling beneath the surface.

Frass (Termite Droppings)

Drywood termites leave behind small, wood-colored droppings near infested areas. They look like tiny wood pellets or coffee grounds.

Why Early Detection is Critical

Termites can go unnoticed for months or even years, causing major damage to…

• Wooden framing and support beams

• Drywall and insulation

• Flooring and subflooring

Catching the first sign can prevent extensive structural damage and save you thousands of dollars in repair costs.
