13 Early Warning Signs Of Termites
Early warning signs of termite infestation include the following:
1. Swarmers
Spotting swarmers indoors or near windows strongly indicates an active termite colony nearby. During the termite mating season, winged reproductive termites, known as swarmers or alates, emerge in large numbers. Mistaken for flying ants, these termites have wings and are attracted to light sources.
After finding a suitable mate, swarmers shed their wings, leaving them behind on windowsills, near light fixtures, or on the floor. While swarmers themselves do not cause damage, their presence signals the existence of a mature termite colony that requires immediate attention to prevent further issues.
2. Visible Termite Workers Or Soldiers
In addition to spotting swarmers, you may also come across termite workers or soldiers, which are different from swarmers in appearance. Termite workers are pale-colored insects with soft bodies and are responsible for the damage they cause. They are usually found near infested areas such as wooden structures or tunnels.
Soldiers, on the other hand, have larger heads and mandibles, which they use for defense. Finding termite workers or soldiers clearly indicates an active termite infestation.
3. Discarded Wings
One of the early warning signs of a termite infestation is the appearance of discarded wings. After termites swarm and mate, they shed their wings, which can be found near windowsills, light sources, or on the ground. These discarded wings are often similar in size and shape and may be clustered together.
Finding these wings indoors or in clustered areas around your property indicates a termite colony is nearby. Not all termites have wings, and the presence of discarded wings suggests that a new colony may have established itself and requires immediate attention to prevent further damage.
4. Mud Tubes
Another one of the early warning signs of termite infestation is the appearance of mud tubes, which termites construct to protect themselves while traveling from the soil to their food source. These tubes, made of soil, saliva, and termite feces, can be found along foundation walls, crawl spaces, or areas where the ground meets the structure.
However, it’s important to note that not all termite species create mud tunnels. Subterranean termites, nesting in soil and requiring moisture, are commonly associated with mud tubes, while drywood termites infest dry wood and do not build such structures. Identifying the specific termite species is crucial for accurate assessment and treatment. Professional inspection and identification may be necessary for effective management.
5. Frass
Drywood termites have a unique behavior of expelling their fecal pellets, known as frass, from small holes in infested wood. These pellets are small, granular, and often have a wood-colored or dark brown appearance. The presence of frass is a clear indicator of drywood termite activity and can help locate their nesting area within a structure.
Regular inspections and identification of frass can aid in early detection and prompt treatment of drywood termite infestations. Please note: Frass is primarily associated with drywood termites; not all termite species leave behind visible frass. Subterranean termites, for example, do not produce frass as they construct mud tubes and underground tunnels.
6. Clicking Sounds
When soldier termites are disturbed, they can exhibit a unique defensive behavior by banging their heads against the wood. This action produces a distinctive clicking sound, serving as auditory early warning signs of termite activity. The clicking noise is a form of communication among the termite colony members and is intended to intimidate potential threats.
Listening for these unusual clicking noises in infested areas, especially near wooden structures or infested wood, can help detect the presence of termites and prompt further investigation for proper identification and treatment.
7. Wood Damage
Termites are known for their ability to create tunnels and galleries within wooden structures, which can result in visible damage. One of the signs to look out for is hollowed or damaged wood, where the termites have consumed the interior portions, leaving a weakened structure.
Additionally, you may notice blistering or darkening of wood surfaces, indicating moisture or termite activity. These visual indicators of termite activity serve as early warning signs and should prompt further investigation.
8. Hollow-Sounding Wood
You may notice a distinct hollow or papery sound when tapping or knocking on wood infested with termites. This is because termites feed on the internal structure of the wood, hollowing it out and weakening its integrity. The damage caused by termites compromises the density and solidity of the wood, resulting in a different sound when tapped or knocked.
This auditory clue can help detect termite infestations, especially when combined with other signs such as visible damage, discarded wings, or frass.
9. Sagging Floors Or Doors
Termite damage can have significant structural implications, leading to various signs of compromised wood. One such sign is the sagging of floors, which occurs when termites have hollowed out the wooden supports or subfloor, causing it to lose strength and stability.
Additionally, termite infestations can affect the operation of doors and windows. As termites consume the wooden frames and surrounding structures, they can distort the shape or cause warping, making it challenging to open or close doors and windows smoothly.
10. Tightening Or Bulging Drywall
Termite infestations in wooden structures behind drywall can cause the drywall to warp, bubble, or develop visible irregularities in texture. Bulges, bumps, or undulations on the drywall surface may indicate termite activity behind the walls. Prompt investigation and addressing of these signs are crucial to prevent further damage to the walls’ structural integrity and ensure the property’s safety.
11. Tight-Fitting Doors Or Windows
As termites create tunnels and galleries within wooden structures, they can affect the alignment and functionality of doors and windows. The damage caused by termites can result in the warping or weakening of the surrounding wood, causing doors or windows to become misaligned or fit too tightly.
You may notice that doors or windows are difficult to open or close smoothly, or they may stick or jam. These changes in alignment can be an indication of termite activity.
12. Paint Blisters Or Peeling
If you notice blistering or peeling paint on wooden surfaces, particularly in areas prone to termite infestations, it could be a sign of termite activity. When termites infest wood, they create tunnels and galleries beneath the surface. As they feed on the cellulose within the wood, they can cause the paint to blister or peel.
This occurs because the termites disrupt the adhesion between the wood and the paint, separating the paint layer from the underlying surface.
13. Maze-Like Patterns
Termite infestations can manifest as maze-like patterns in wooden furniture, floorboards, or walls. These patterns, also known as galleries, are created by termites as they excavate tunnels within the wood. The termites hollow out the wood, leaving a network of interconnected passages that resemble intricate mazes.
These patterns may be visible on the surface of the wood or can be detected by tapping or probing the affected area. If you observe unusual patterns or structures on wooden surfaces, it could indicate termite activity.
What To Do If Termites Are Present
Remember, early detection is crucial in preventing extensive damage from termites. If you observe any of these signs, it is recommended to consult a professional termite inspector or pest control specialist for a thorough examination and appropriate treatment. Our guides and these professionals can offer practical solutions to termite infestations.
Conclusion
Recognizing the early warning signs of termite infestation is crucial for timely intervention and preventing extensive damage. From the presence of swarmers and discarded wings to mud tubes, frass, and structural indicators such as wood damage and hollow-sounding wood, these signs can help you identify termite activity. If you notice any of these early warning signs of termites, it is important to seek professional inspection and treatment to mitigate the impact of termites on your property.
