Playing detective in your own home isn’t quite what you imagined as a homeowner, yet here you are, searching for tiny clues of a termite invasion. Understanding how to identify termite holes is crucial since these tiny pests are masters of hide and seek. So, let’s equip you with the knowledge to spot these minuscule hideouts so you can take proactive steps to get rid of them.
In this article, we’ll dive into the specifics of termite holes, giving you practical tips to identify them and compare them with holes created by other pests. So put on your Sherlock Holmes hat, and let’s get started.
What are Termite Holes?
Termite holes are small openings, typically 1/8 of an inch wide, created by termites during their mating season. The holes, also known as “exit holes,” serve as gateways for swarmers — the winged termites. These swarmers take their inaugural flight from the nest through these holes, embarking on a mission to mate and establish new colonies.
Interestingly, once the swarmers have departed, the termite colony doesn’t just leave these holes open. Nymph termites, which are young termites, take on the task of sealing them. They use a mixture of their feces, soil particles, and wood particles, effectively camouflaging the holes with the surrounding wood or drywall.
However, the absence of termite holes does not mean you don’t have a termite infestation in your home. Not all types of termites create holes; only drywood termites do. Therefore, it’s important to be vigilant for other signs of termite activity, like mud tubes.
What Do Termite Holes Look Like?
Identifying termite holes is a critical step in recognizing an infestation, but what exactly should you be looking for? Termite holes are often filled with a brown, cement-like substance composed of termite feces, soil, and wood particles. The color and texture of this sealing material can vary slightly, but it generally resembles a small patch of plaster or mud.
How big are termite holes? Termite holes are typically round and quite tiny, usually about 1/8 inch in diameter or smaller — about the size of a pinhead. This small size can make them challenging to spot without a close inspection.
You can find termite holes in a variety of places. While they are most commonly seen in wood, the primary habitat and food source for drywood termites, they can also be found in drywall and in the ground, depending on where the termites have established their colony. Here’s what termite holes look like, depending on where they’re located:
Termites Holes in Drywall
Holes caused by termites in drywall can be particularly insidious due to their discreet nature. On drywall, these holes often appear as tiny pinpricks, so small and inconspicuous that they can easily be overlooked during a casual inspection.
You might also notice the paint in the drywall starting to bubble or flake off. This happens because termites bring moisture into the drywall as they tunnel through it. The added moisture disturbs the integrity of the drywall and the paint, leading to these visible changes on the surface.
Termite Holes in the Ceiling
A telltale sign of termites in the ceiling is termite holes. These holes are not just exit points for termite swarmers but also serve as disposal sites for their fecal matter and waste.
When inspecting your ceiling, look for small openings and frass or termite droppings near them. The presence of termite droppings near these holes is a strong indicator of their activity. Frass typically appears as a pile of small, pellet-like granules or powdery residue and can often be found directly below the termite holes in the ceiling.
Termite Holes in Floors
Termite holes in the floor also appear as small pin-sized openings, which can be challenging to spot. They can appear in hardwood floors and even laminates, affecting not only the visible top layer of the flooring but also the subfloor and structural supports underneath. This hidden damage can compromise the integrity and safety of your home.
There are other signs to watch for that may suggest termite activity in the ground:
- Squeaky floors
- A hollow sound when tapping on the wood
- The presence of loose floor tiles indicates that termites have been feeding on the material underneath.
Termite Holes in Furniture
Termite invasions aren’t limited to the structural elements of your home; your wood furniture can also fall prey to these voracious pests. You may be able to spot termite holes in built-in cabinets, antiques, door and window frames, and more.
Detecting termite activity in furniture is often easier than in other parts of your home, like ceilings or drywall. This is because termites confined within furniture have limited space to hide their presence. When inspecting your furniture for termite damage, look for the same small, pin-sized holes, as well as buckling paint, sunken spaces, and frass.
Termite Holes in Trees
While termite infestations are often associated with human-made structures, these pests can also target trees, particularly dead or decaying wood. It’s less common to find termites in live trees, but it’s not unheard of, especially in the South with species like Formosan termites or conehead termites, which are known for their aggressive behavior.
The termite holes are usually found at the base of the tree and have the same pin size as in other structures. Termites can also use mud tubes to get to pruning scars higher up on the tree. These holes can be an entry point for the termites as they seek out the cellulose-rich wood. Another sign of termite infestation in trees is the presence of a mound of dirt at the base or a nest within the tree.

Other Insects That Make Holes
Termites aren’t the only insects that leave behind holes as evidence of their presence. It’s essential to correctly identify the type of insect responsible for the damage you’re observing, as this will greatly influence the approach and methods for effective pest control.
Here are a few common culprits that look like termites or that can create similar holes but are, in fact, entirely different pests:
1. Carpenter Ants
Carpenter ants, often mistaken for termites, don’t consume wood; instead, they excavate it to build their nests. This results in distinctive damage patterns. The galleries carved out by carpenter ants have a smooth, almost polished appearance. This contrasts with the rough, ragged texture left behind by termites, who eat the wood they infest.
Carpenter ants meticulously remove wood debris to create their nests. This frass is ejected from the galleries through small holes. Unlike termites, carpenter ants do not mix soil into their tunnels or galleries. So, the absence of soil and the presence of clean, smooth galleries are key indicators that you’re dealing with carpenter ants, not termites.
2. Powderpost Beetles
Powderpost beetles also target wood, but there are some distinct characteristics that set them apart. The adult beetles lay their eggs in the cracks and crevices of wood. Once hatched, the larvae burrow deeper into the wood, feeding on it and growing over time.
As the larvae mature into adults, they make their way to the surface of the wood. At this point, they drill tiny exit holes to emerge. These holes are typically the size of a pinhead, similar in size to those made by termites but often accompanied by a fine, powdery, sawdust-like substance.
3. Carpenter Bees
The most noticeable characteristic of carpenter bee damage is the shape and size of the holes they create. Unlike the irregular, pinhead-sized holes made by termites, carpenter bees drill almost perfectly round holes about the diameter of a finger. Another sign of carpenter bee activity is the presence of a sticky yellow substance near these holes.
Carpenter bees are solitary creatures and do not live in colonies like termites or ants. This means that while they can cause damage to wood, they typically do not create widespread infestations.
4. Wood Wasps
Wood wasps, also known as horntails, are another type of insect that can create holes in wood, but their impact differs significantly from termites and other wood-boring pests since they do not colonize. In addition, wood wasps generally target damaged or decaying softwood, including lumber that may already be weakened by fungus or rot.
They lay their eggs directly into the softwood, and after the eggs hatch, the larval stages of the wasp spend a few days to weeks boring through the wood to emerge. The holes they create during this process are circular and fairly uniform, with a diameter of around 1/8 inch.
How to Cover Termite Holes
Covering termite holes can stop termites from using these specific exits but does not eliminate the infestation. Termites are likely to create alternative exit holes, potentially causing more damage to the wood.
The most effective way to deal with a termite infestation is by contacting a termite control professional. They can provide a comprehensive treatment plan to eliminate the termites and prevent future infestations.
Once the termite infestation has been professionally treated and you’re certain the termites are gone, you can focus on repairing the wood. Here’s what to do:
- Select the right caulk: Choose a caulk that is suitable for the type of wood and the location (interior or exterior).
- Thin fitting tube: Use a caulk with a thin fitting tube for precision in filling the small termite holes.
- Fill the holes: Carefully fill each hole with caulk, ensuring it is fully plugged.
- Smoothing out: After filling, smooth out the surface of the caulk to match the surrounding area of the wood.
- Drying and finishing: Allow the caulk to dry completely. You may then paint or varnish over the caulk to match the rest of the wood, improving the overall look and restoring the aesthetic appeal.
Other Signs of a Termite Infestation
While termite holes are a clear indicator of an infestation, there are several other signs of a termite infestation in your home. Being aware of these signs is crucial for early detection and effective treatment. Here are key indicators to watch out for:
- Presence of frass: Frass, or termite droppings, often resembles fine sawdust or small pellets. They are formed when termites excavate through wood.
- Mud tubes: Subterranean termites build mud tubes for protection as they travel between their colony and food sources. These tubes are often found near the foundation of a home and are a telltale sign of subterranean termite infestation.
- Hollow sounds in wood: Termites consume wood from the inside out, leaving a thin veneer of timber or paint. When you tap on areas where termites are present, the wood will sound hollow due to the damage inside.
- Discarded wings: After swarming to find a place to start a new colony, termite swarmers shed their wings. Finding discarded wings near windowsills and doors is a common sign of termite activity.
- Warped doors and stiff windows: Termites introduce moisture into doors and windows, which can cause warping. This makes doors and windows difficult to open and close.
FAQ About Termite Holes
Should I Plug Termite Holes?
No, you should not plug termite holes if there is an active termite infestation. Covering the holes while termites are still present will force them to create new tunnels and exit routes, causing additional damage to the wood. It’s essential first to ensure that the termite infestation is completely eradicated by a professional before plugging any holes.
When Do Termites Make Holes?
Termites typically make holes during their mating season, which usually occurs in the warmer months of spring and summer. This is the time when conditions are favorable for them to leave their nests.
The warmer temperatures and increased humidity during these seasons provide the ideal environment for swarmers (winged termites) to emerge from their nests for their nuptial flight. The holes created are used as exit points for these swarmers as they embark on their journey to establish new colonies.
What is the Difference Between Termite Holes and Termite Tunnels?
Termite holes and termite tunnels serve different purposes for termites and are characteristic of different types of termite species.
- Termite holes: Termite holes are primarily associated with drywood termites. These are small openings that the termites create in wood for swarmers (winged termites) to exit during mating season.
- Termite tunnels: Termite tunnels, commonly known as mud tubes, are primarily used by subterranean termites. These termites build mud tubes as protective pathways from their colony in the soil to their food sources above ground, typically wood found in human structures.
When to Call a Professional
Dealing with termites is a serious challenge that can have significant implications for the integrity and safety of your home. While identifying termite holes is a crucial first step in recognizing a potential infestation, it’s important to understand that effectively dealing with termites is not a DIY task.
If you notice termite holes or any other signs of termite activity, the best course of action is to call in a termite control expert in your area.
