People call termites “silent destroyers” because they remain hidden for long periods. In many homes, they live inside walls for years before homeowners notice them. By that time, a termite colony may already be growing.
Knowing the signs of termite activity helps homeowners act sooner. This guide explains common signs of termite damage in walls, what to look for near drywall and baseboards, and when to call for professional termite control.
Key Takeaways
- Mud tubes, swarmers, and hollow-sounding wood are key signs of termite activity.
- Subterranean termites are a common termite concern in McKinney homes.
- Pinholes, frass, peeling paint, and damaged wood can point to termites inside walls.
- A professional termite inspection can confirm the presence of termites and guide your termite control plan.
Signs of Termites in Your Walls
Termites often stay hidden and move inside walls while feeding on wood. Because you rarely see them, the first clues come from small changes in the home.
Mud Tubes
Mud tubes are one of the clearest signs of termite activity. Subterranean termites build mud tubes to travel from the soil to a food source without drying out. You may see mud tubes near baseboards, in a crawl space, or along exterior walls.
Swarmers and Discarded Wings
Swarmers are winged termites that leave a termite colony to start a new one. A termite swarm often happens during warm weather. If you see swarmers near windowsills, door frames, or lights, it may mean a termite colony is nearby or inside the structure.
After swarmers land, they drop their wings. Discarded wings on windowsills or near baseboards are often one of the first visible signs of termite activity.
Hollow-Sounding Wood
When termites tunnel through wood, they eat the inside and leave a thin outer shell. That damage makes trim, floorboards, and other wooden structures sound hollow when tapped.
What Wall Damage Can Look Like
Wall damage from termites does not always look obvious. It can look like normal wear or water damage, which makes early detection harder.
Pinholes and Frass
Small pinholes in drywall can be a warning sign when termite activity reaches the surface. You may also see frass, another term for termite droppings, that look like tiny pellets or grains near baseboards, windowsills, or door frames.
Drywood termites leave frass, while subterranean termites build mud tubes. Both can point to a termite infestation.
Peeling Paint or Bubbling Drywall
Peeling paint or bubbling drywall can have several causes, but in some cases, termites behind the wall may cause it. If these changes appear alongside other warning signs, they may indicate a termite problem.
Sagging Floors and Damaged Wood
As termites continue feeding, the wood can weaken. That may lead to sagging floors, cracked trim, or other damaged wood around the home. These signs of termite infestation often mean the problem has been there for a while.
Safe Ways to Check for Termites
You can check key areas around your home for signs of termite activity without opening walls.
Tap Wood and Trim
Lightly tap baseboards, floorboards, and door frames. If the wood sounds hollow, termites may be inside.
Look in the Crawl Space
Many termite issues start low in the home. Check the crawl space for mud tubes, damaged wood, or other signs of termites.
Check Outside Walls and Window Areas
Walk around the home and inspect exterior walls, windowsills, and nearby trim. Mud tubes, peeling paint, or weakened wood may indicate an active infestation.
