At Rid-A-Bug Exterminating, we've been serving homeowners across North Carolina, South Carolina, and Virginia since 1972, helping them identify and address termite problems before they become catastrophic. With our decades of experience, we've learned that early detection is crucial for minimizing damage and treatment costs.
In this blog post, we'll explore the six most common signs of a termite infestation, helping you better protect your home.
Understanding Termites: The Silent Destroyers
Before diving into the warning signs, let's understand what makes termites such effective destroyers.
Types of Termites in the Carolinas and Virginia
In our service area, homeowners typically encounter three main types of termites:
- Subterranean Termites
- Most common and destructive type in our region
- Live in soil and build mud tubes to reach food sources
- Colonies can contain millions of individuals
- Require contact with moisture and soil to survive
- Formosan Termites
- Aggressive subterranean termite subspecies
- Found primarily in coastal areas
- Can create carton nests above ground if moisture is available
- Capable of causing severe damage in shorter time frames
- Drywood Termites
- Don't require soil contact
- Live entirely within the wood they infest
- Typically form smaller colonies than subterranean termites
- Can infest furniture, trim, and structural wood
The Termite Life Cycle and Colony Structure
Termites live in highly organized colonies with different castes performing specific functions:
- Workers: Pale, soft-bodied insects that consume wood and feed other colony members
- Soldiers: Defend the colony with large mandibles; have larger heads than workers
- Reproductives/Swarmers: Winged termites that leave the colony to mate and establish new colonies
- King and Queen: Primary reproducers responsible for populating the colony
Understanding this structure helps in identifying certain signs of termite activity, particularly during swarming seasons when reproductive termites emerge.
Six Key Signs of a Termite Infestation
Now, let's examine the most common indicators that termites might be feasting on your home.
1. Mud Tubes on Exterior Walls
One of the most visible signs of subterranean termite activity is the presence of mud tubes.
What They Are:
- Pencil-sized tunnels made from soil, wood particles, and termite saliva
- Serve as protected pathways that maintain the humidity termites need to survive
- Connect the soil (where the colony lives) to the wood (their food source)
Where to Look:
- Foundation walls
- Support piers
- Floor joists
- Crawl spaces
- Along sill plates
- Between cracks in concrete or brick
How to Check: Break open a small section of the tube. If it's actively used, you'll likely see termites inside, or the tube may be repaired within days. Even empty tubes warrant professional inspection, as they might indicate previous activity or termites might be using other entry points.
2. Discarded Wings
Reproductive termites (also called alates or swarmers) have wings, which they shed after finding a mate and suitable location for a new colony.
What They Look Like:
- Small, translucent wings of equal size and shape
- Often found in piles near windowsills, doorways, or light fixtures
- Resemble fish scales
When to Look:
- Typically during spring and early summer
- After rainfall when humidity is high
- Often during mornings or afternoons
Read more in our blog post about pests to expect after heavy rains.
Why This Matters: Finding discarded wings inside your home is a serious concern because it suggests that termites have likely chosen your home as a site for a new colony. Each successful pair of reproductive termites can establish a colony that will grow to thousands of members over time.
3. Hollow-Sounding Wood
Termites consume wood from the inside out, following the grain and leaving the surface intact.
How to Detect:
- Tap on wood surfaces with a screwdriver handle or similar tool
- Termite-damaged wood will sound hollow or papery
- The surface may feel paper-thin when pressed
Where to Check:
- Baseboards and trim
- Window and door frames
- Support beams
- Floor joists
- Wooden furniture
Advanced Detection Methods: Professional inspectors now use several advanced technologies to detect termite activity inside walls:
- Acoustic detectors that can hear termite movement
- Infrared cameras that detect temperature differences caused by termite activity
- Microwave technology that can "see" through walls
- Termite detection dogs trained to smell the pheromones termites produce
4. Frass (Termite Droppings)
Drywood termites, in particular, leave behind distinctive droppings called frass.
What It Looks Like:
- Small, wood-colored pellets
- Often described as resembling coffee grounds or sawdust
- Typically found in small piles
Where to Look:
- Below infested wood
- On window sills
- Under furniture
- Along baseboards
What Makes Frass Distinctive: Frass is different from regular sawdust because of its distinctive pellet shape. The pellets are typically six-sided and all similarly sized, unlike the irregular particles created by carpenter ants or wood-boring beetles.
5. Tight-Fitting Doors and Windows
Termite activity can cause wood to warp due to the tunneling and moisture they introduce.
What to Look For:
- Doors or windows that suddenly become difficult to open or close
- Visible warping or sagging of door frames
- Windows that stick for no apparent reason
Why This Happens: As termites consume wood, they create galleries filled with moisture. This moisture, along with the structural weakening caused by their feeding, can cause wood to swell or sag, affecting the function of doors and windows.
Additional Signs:
- Uneven or bubbling paint
- Baseboards pulling away from walls
- Buckling wood or laminate flooring
6. Visible Damage to Wood Structures
As termite infestations progress, the damage becomes more apparent.
Visual Indicators:
- Wood that appears crushed at structural bearing points
- Maze-like patterns in exposed wood
- Blistering or peeling paint that resembles water damage
- Small holes in drywall
- Sagging floors or ceilings
- Visible tunnels or galleries when wood is broken open
Most Vulnerable Areas:
- Where wood meets soil
- Near plumbing penetrations
- Attic spaces
- Crawl spaces
- Basements
- Areas with previous moisture issues
The Difference Between Termite Damage and Water Damage: Termite damage often follows the grain of the wood and contains mud tubes or frass. Water damage typically affects wider areas and may show signs of mold. However, the two often occur together since termites are attracted to moisture-damaged wood.
What to Do If You Suspect Termites
If you notice any of the signs above, it's important to take action quickly.
Immediate Steps
- Document the evidence: Take photos of any signs you've found
- Avoid disturbing the area: Don't break open mud tubes or disturb visible termites
- Don't apply over-the-counter pesticides: These may disperse the termites without eliminating the colony
- Contact a professional: Schedule a thorough termite inspection
The Professional Inspection Process
A professional termite inspection typically includes:
- Visual examination of accessible areas inside and outside your home
- Probing of wood structures to check for damage
- Identification of conditions conducive to termite activity
- Assessment of previous treatments or damage
- Recommendation for treatment options
At Rid-A-Bug, our inspectors are fully licensed and certified to perform thorough termite inspections, including Wood-Destroying Insect Reports (WDIRs) required for real estate transactions in North Carolina, South Carolina, and Virginia.

Prevention Strategies: Protecting Your Home
While early detection is crucial, prevention is even better. Here are effective strategies to reduce your risk of termite infestation:
Moisture Management
Since many termites are attracted to moisture-damaged wood, controlling moisture is essential:
- Fix leaky pipes, faucets, and air conditioning units promptly
- Ensure proper drainage around your foundation
- Maintain gutters and downspouts to direct water away from your home
- Use dehumidifiers in damp areas like basements
- Ensure adequate ventilation in crawl spaces
- Address any standing water issues around your property
Structural Modifications
Making your home less accessible to termites can significantly reduce infestation risk:
- Maintain at least 6 inches between soil and wooden structural elements
- Remove wood debris from around your foundation
- Keep firewood, lumber, and paper away from your foundation
- Use termite-resistant materials for additions or renovations
- Install physical barriers during construction
- Consider crushed stone barriers around your foundation
Regular Inspections
The best defense is vigilance:
- Conduct your own visual inspections quarterly
- Schedule professional termite inspections annually
- Pay special attention during spring when swarmers emerge
- Monitor previously treated areas for signs of new activity
- Be especially vigilant after nearby construction or soil disturbance
Professional Preventive Treatments
Preventive termite treatments can provide long-term protection:
- Liquid termite barriers around your foundation
- Termite bait systems that eliminate colonies before they infest
- Treated building materials for new construction
- Wood treatments that deter termite feeding
Integrated Pest Management for Termites
At Rid-A-Bug, we utilize Integrated Pest Management (IPM) principles, an environmentally sensitive approach that combines common-sense practices with targeted treatments. For termites, this includes:
- Thorough inspection and accurate identification
- Monitoring for early detection
- Habitat modification to make your home less attractive to termites
- Targeted applications of termiticides when necessary
- Use of alternative control methods when appropriate
- Follow-up inspections to ensure effectiveness
IPM emphasizes addressing the root causes of pest problems rather than just treating symptoms, resulting in more sustainable, long-term protection for your home.
FAQs About Termite Detection
How often should I have my home inspected for termites?
Annual professional inspections are recommended for most homes. However, if your property has had previous termite issues or is in a high-risk area, semi-annual inspections might be advisable. Between professional inspections, conduct your own visual checks for the signs outlined above.
Can I treat termites myself?
While DIY termite treatments are available, they're generally not recommended for active infestations. Termite colonies can be massive and difficult to locate, and incomplete treatment often fails to eliminate the problem. Professional treatment addresses the entire colony and provides more reliable results.
Are certain homes more susceptible to termites?
Yes, several factors can increase your home's vulnerability to termites:
- Homes with wood-to-soil contact
- Properties with moisture problems
- Houses in warmer climates
- Homes with previous termite issues
- Older structures with existing damage or vulnerabilities
- Properties near wooded areas
How quickly can termites damage a home?
Termite damage typically develops slowly over time. A mature subterranean termite colony might consume about a pound of wood per day under ideal conditions. While significant structural damage generally takes years to develop, the financial impact increases the longer an infestation goes untreated.
Does homeowners insurance cover termite damage?
Most standard homeowners insurance policies do not cover termite damage, as it's typically considered preventable through proper maintenance. This makes early detection and prevention even more important for protecting your investment.
