7 Signs You Have a Hidden Termite Problem in Your San Marcos Home

by | Jan 27, 2026 | San Marcos Pest Control | 0 comments

Termites are a homeowner`s nightmare, especially in areas like San Marcos where the climate can be conducive to their proliferation. These wood-destroying pests can cause significant damage before you even realize they are there.

Here are seven signs that may indicate you have a hidden termite problem.

1. Mud Tubes

Mud tubes are one of the most common signs of a subterranean termite infestation. These pencil-thin tubes can typically be found on walls or foundation areas. Termites use them to protect themselves from predators and maintain a moist environment while they forage.

2. Hollow Sounding Wood

If you tap on wooden surfaces and they sound hollow, it could be due to termites consuming the wood from the inside out. This often goes unnoticed until significant damage has already occurred.

3. Frass

Frass is a term for termite droppings. If you notice small piles of what looks like sawdust near wooden structures, it could be frass, indicating a drywood termite infestation.

4. Swarmers

Swarmers are winged termites that emerge to establish new colonies. If you see a swarm of what looks like flying ants around your home or discarded wings near windows and doors, it may be time to call in a professional.

5. Warped or Bubbling Paint

When termites tunnel through walls, they can create moisture that causes paint to bubble or peel. If you notice unusual warping, it might be an indication of termites.

6. Tight-Fitting Doors and Windows

As termites damage wood, it can cause wood to warp, making doors and windows tight-fitting or hard to open. This is often mistaken for normal settling of the house, which allows the problem to persist unnoticed.

7. Clicking Noises

Termites are noisy eaters. If you put your ear close to an infested piece of wood, you might hear them clicking away as they chew through the wood. Soldiers also bang their heads against the wood to signal danger to the colony.

If you notice any of these signs in your San Marcos home, it’s crucial to act quickly. Termite infestations can cause severe structural damage if left unchecked.
