Termites may be small, but the damage they can cause is anything but. These silent destroyers can compromise the integrity of your home without you even knowing it. That's why recognizing the signs of a termite infestation early is crucial. In this blog, we'll walk you through the key indicators that it's time to call in a professional.
1. Unusual Sounds in Your Walls
If you hear faint clicking sounds coming from your walls, it could be termites. These noises are made by soldier termites banging their heads against the wood when disturbed, or when termites are eating. It's like a tiny construction site bustling inside your walls that you can’t see but can occasionally hear[^1]. This sound is particularly noticeable at night when your home is quieter, and it's one of the first and most telling signs that termites are present in your home. Ignoring these sounds can lead to extensive damage because termites often wait until their population grows and resources are depleted before moving on.
2. Swarms of Winged Insects Indoors
Winged termites, or swarmers, indicate an active colony nearby. Swarms are often seen in the evenings or after rainfall. If you find discarded wings around windowsills or doors, it’s a sign you should not ignore. These insects look similar to winged ants, but a closer look can reveal their straight antennas and uniformly sized wings[^2]. Spotting a swarm means the colony is mature and ready to expand, potentially causing severe damage if left unchecked. It's vital that if you see any termite swarmers in your home, you call a pest control service immediately to curb any expansion.
3. Hollow Sounding Timber
Tap exposed wood in and around your home. If it sounds hollow, termites might have consumed the inside. Termites eat wood from the inside out, leaving a thin layer of timber or paint. A professional termite inspection can confirm if hollow wood indeed indicates a termite presence[^3]. This type of damage can compromise structural integrity, especially if left untreated over time. Catching this sign early and addressing it can save vast sums in repair costs and ensure your home remains sturdy.
4. Cracks on Internal Walls and Floors
Cracks can appear due to termites eating away the structure within beams or support frames. While not every crack is caused by termites, they can weaken the structural integrity of your home. Termites can stealthily attack from below, slowly hollowing valuable supports[^4]. Sometimes these cracks are dismissed as settlement cracks, especially in older homes, but erring on the side of caution is wise. Engaging a termite professional ensures any damage or potential infestation is tackled swiftly.
5. Doors and Windows Are Tough to Open
Stiff doors or tight-fitting windows can be a sign of moisture build-up in frames and floors, which termites may have caused. Their waste creates an environment that holds moisture, altering the wood. This happens when the humid and rainy conditions typical to certain climates mix with termite activity, causing the wood to warp[^5]. Homeowners might initially dismiss this as a humidity issue, not realizing termites are also involved. A termite inspection could reveal hidden damage and maintain your home's proper fitments.
6. Tunnels in Wood Structures
Mud tubes or tunnels are not always visible, but if you detect them, it's a clear indication of termite activity. These are built by termites to travel and protect themselves from open air. Such structures showcase the termites' need for a humid environment[^6]. The tubes create pathways for constant movement, avoiding exposure to predators and dehydration. Detecting these early can help fumigate the infestation before the termites share those tunnels with more colonies. DIY methods often fail at this, as they don't cover underground connections.
7. Peeling Paint That Looks Like Water Damage
Since termites produce moisture as they eat through wood, it can lead to bubbling or peeling paint on walls. This could mimic symptoms of water damage. Moisture accumulation signifies termite presence[^7], making moisture meters a valuable tool during professional inspections. Ignoring these signs and merely repainting could mean overlooking an infestation underneath waiting to expand its territory further.
8. Frass or Termite Droppings Found
Termite droppings, known as frass, are small, wood-colored pellets near infested areas. This is a sign of drywood termites actively tunneling and could signify a severe infestation scenario. A concentrated pile of frass often means a nearby infestation, as this waste often accumulates in termite kick-holes[^8]. Having a professional identify and deal with these mounds can prevent the colony from growing undetected. DIY attempts to eliminate the droppings could scatter them, making them harder to trace.
9. Damage to Garden or Outdoor Wooden Structures
Check your garden shed, fence posts, and other outdoor wooden areas. If these structures show weak spots or collapse, it’s essential to investigate further as termites could be the culprit. Termites often start attacking external wood before making their way indoors[^9]. Signs of damage outside can indicate an impending threat to any wooden features inside your home. Protective measures by professionals can mitigate such risk by treating your yard comprehensively.
10. Neighboring Homes Have Infestations
If nearby homes have confirmed infestations, it might be time to inspect your property. Termites travel, and a colony nearby increases the risk of them invading your home. Having a proactive approach by scheduling an inspection[^10] ensures that you catch any pest activity early. Such inspections will include preventive treatments that establish barriers, reducing the risk of termite migration to your home.
