Termites are often called “silent destroyers” because they can live in your home for years without being noticed. By the time visible damage appears, the colony may already be well-established. Knowing the early warning signs can help you take action before swarm season starts and protect your home.

Don't wait for swarm season to discover a termite problem. If you've noticed any unusual signs around your home, contact Hartz Pest Control at (713) 999-6817 today for a thorough inspection. Early detection makes all the difference.

What Happens Before Termites Swarm

Swarm season in the Greater Houston Area typically kicks off in early spring when temperatures warm up and humidity rises. But here's what most homeowners don't realize: the termites you see flying around during swarm season didn't just arrive. They've been living in or near your home for a long time, quietly building their colony.

A termite colony can take three to five years to mature before it produces swarmers. During that time, worker termites are busy eating away at wood, causing damage you can't see from the outside. Swarmers are actually the colony's way of expanding to new locations. If you spot them inside your home, it often means the colony is already well-established.

The key to protecting your home is learning to recognize the subtle signs of termite activity before the swarm happens.

Hollow-Sounding Wood

One of the earliest indicators of a hidden termite problem is wood that sounds hollow when you tap on it. Termites eat wood from the inside out, leaving only a thin layer on the surface. This creates empty spaces inside beams, doorframes, and baseboards.

Walk through your home and gently tap on wooden surfaces with your knuckles:

Door frames and window frames
Baseboards along walls
Wooden support beams in crawl spaces or basements
Wooden furniture that sits against walls

If the wood sounds hollow or papery instead of solid, termites may have already done significant damage. You might also notice that the wood feels softer than it should when you press on it.

Mud Tubes on Foundation Walls

Subterranean termites, the most common type in Houston, build mud tubes to travel between their underground nests and the wood they're eating. These tubes are about the width of a pencil and look like thin, dried mud trails running up foundation walls, concrete piers, or along basement walls.

Check these areas regularly:

Exterior foundation walls, especially near soil contact
Inside crawl spaces and basements
Around plumbing penetrations where pipes enter your home
Along concrete slabs and expansion joints

Mud tubes protect termites from dry air and predators while they move back and forth. If you find one, don't remove it immediately. Contact Hartz Pest Control so we can inspect the situation and determine how active the infestation is.

Small Piles of Droppings

Drywood termites leave behind small piles of droppings that look like sawdust or coffee grounds. These droppings, called frass, are usually found in small mounds beneath wooden furniture, windowsills, or door frames. Unlike carpenter ants, which push wood shavings out of their tunnels, termite droppings are pellet-shaped and uniform in size.

Look for frass in these locations:

Under wooden furniture or cabinets
On windowsills and around window frames
Near small holes in wood surfaces
In corners of rooms with wooden trim

If you notice these tiny piles appearing regularly, even after cleaning, it's a sign that termites are actively feeding nearby.

Cracked or Bubbling Paint

Paint that bubbles, cracks, or peels away from wood surfaces can indicate moisture damage. But it can also be a sign that termites are working underneath. As termites tunnel through wood, they create uneven surfaces that cause paint to buckle. Additionally, the moisture from mud tubes and termite activity can make paint look water-damaged.

Pay special attention to:

Window frames and door frames
Wooden siding on the exterior of your home
Baseboards and crown molding
Any wooden surfaces that seem to have moisture issues without an obvious water source

This sign is easy to overlook because it resembles normal wear and tear. But if the paint damage doesn't match up with any water leaks or humidity problems, termites could be the cause.

Tight-Fitting Doors and Windows

Doors and windows that suddenly become difficult to open or close might seem like a minor annoyance. But this can actually be an early warning sign of termite damage. As termites eat through wooden frames, they create moisture that causes the wood to swell. This swelling makes doors stick in their frames and windows hard to slide open.

Notice if:

Doors that used to open smoothly now stick or drag
Windows require extra force to open or won't stay open
Door frames feel warped or uneven
Gaps around doors and windows have changed size

While humidity can also cause wood to swell, especially in Houston's climate, pest control professionals can determine whether termites are contributing to the problem.

Discarded Wings Near Entry Points

Before swarm season officially begins, you might start finding tiny discarded wings near windowsills, door frames, or light fixtures. When termite swarmers find a good location to start a new colony, they shed their wings because they no longer need them. Finding piles of these wings is one of the clearest signs that termites have been active in or around your home.

Check these spots regularly:

Windowsills, especially on the interior side
Door thresholds and entryways
Around exterior lights or porch lights
In spider webs near windows

The wings are translucent and about the same size. If you find them, it means swarmers have already emerged, and a colony is nearby or inside your home.

What to Do If You Spot These Signs

If you've noticed any of these warning signs, the most important step is to schedule a professional inspection. Termite damage happens slowly but adds up over time, and the longer an infestation goes untreated, the more expensive repairs become.

Here's what you should do:

Document the signs you've noticed with photos or notes
Avoid disturbing mud tubes or damaged wood until a professional can inspect them
Schedule an inspection before swarm season arrives for the best chance at early intervention

A thorough inspection will identify the extent of termite activity, the type of termites involved, and the best treatment approach for your situation. Modern termite treatment options are effective at eliminating active colonies and protecting your home from future infestations.

Protect Your Home Before Swarm Season

Termites don't wait for permission to damage your home, and neither should you wait to protect it. Spotting the signs early gives you the advantage of addressing the problem before it becomes overwhelming. Whether you've noticed hollow-sounding wood, mud tubes, or discarded wings, taking action now can save you time, money, and stress down the road.

Don't let hidden termites compromise your home's safety and value. Contact Hartz Pest Control at (713) 999-6817 or schedule an inspection online today. We'll help you understand what's happening and create a plan to protect your home for the long term.
