A strange pile near the baseboard. A spot on the wall that suddenly looks different. Something around a window that was definitely not there yesterday.
Small changes around the house are easy to ignore, especially when nothing looks seriously damaged. The problem with termites is that much of their activity happens where homeowners cannot see it. By the time the damage becomes obvious, they may have already been feeding inside the wood for some time.
That matters even more in South Florida, where the warm, humid climate supports several termite species and creates favorable conditions for termite activity.
Knowing the signs of termites can help you recognize when an unusual change around your home deserves a closer look. Below are seven warning signs Miami homeowners should know and what each one could tell you about the type of termite activity taking place.
1. Discarded Wings Around Windows and Doors
Finding a few loose wings may look harmless at first, but their location can make them worth investigating.
Reproductive termites, known as swarmers or alates, leave an established colony to mate and begin new colonies. After swarming, they shed their wings.
Homeowners may find these wings around:
- Window sills
- Sliding doors
- Door frames
- Light fixtures
- Patios
- Other areas where insects are attracted to light
A swarm outside does not always mean termites are already inside the house. Finding swarmers or piles of discarded wings inside, however, deserves much more attention.
In Florida, termite swarming can occur earlier than it does in colder parts of the country because of the climate.
2. Mud Tubes Along Walls or the Foundation
Thin trails of dried mud running along a foundation, garage wall, concrete surface, or other part of the property are among the more recognizable signs of termites, particularly subterranean termites.
Subterranean termites live in the soil and build protected tubes between their colony and a source of wood. These tubes help them move above ground while staying protected from dry conditions.
UF/IFAS identifies mud tubes as strong evidence of subterranean termite activity.
Check areas such as:
- Foundation walls
- Garage edges
- Door frames
- Areas where wood meets concrete
- Plumbing penetrations
- Exterior walls
- Trees and wood near the structure
Do not simply scrape a tube away and assume the problem is solved. Removing the visible tube does not eliminate the colony that created it.
3. Tiny Pellet-Like Droppings Near Wood
A small pile that looks like sand, coffee grounds, or fine pellets can easily be mistaken for ordinary dirt.
With drywood termites, it can be something much more important.
Drywood termites live directly inside the wood they infest. As they create galleries, they push their fecal pellets, commonly called frass, through tiny openings in the wood.
These pellets are typically hard, six-sided particles and may accumulate underneath:
- Baseboards
- Window frames
- Wooden furniture
- Door frames
- Beams
- Attic wood
- Other wooden structures
UF/IFAS identifies these six-sided pellets as one of the key indicators of a drywood termite infestation.
Cleaning up the pile may make it disappear temporarily. If pellets begin accumulating in the same location again, there may be an active colony inside the wood above it.
4. Wood That Sounds Hollow or Feels Soft
A piece of wood can look perfectly normal from the outside while being damaged underneath the surface.
Termites often feed inside wood rather than across an exposed surface. In some cases, only a thin outer layer remains intact.
That is why termite inspectors often tap or carefully probe areas such as:
- Baseboards
- Door frames
- Window frames
- Wooden trim
- Beams
- Flooring
- Other structural wood
Wood that sounds unusually hollow, feels soft, gives way under light pressure, or has lost its normal strength should not be ignored.
UF/IFAS notes that tapping wood and listening for a hollow or papery sound can help identify hidden termite damage, particularly with drywood termites.
5. Tiny Holes Appearing in Wooden Surfaces
Look closely at the area above a suspicious pile of pellets and you may notice another clue: extremely small holes in the wood.
Drywood termites create what are commonly called kick-out holes. These openings allow the colony to push frass out of its galleries.
The holes can be only about 1 to 2 millimeters wide, which makes them very easy to overlook.
They may appear in:
- Window trim
- Door frames
- Wooden ceilings
- Furniture
- Beams
- Cabinets
- Other exposed wood
One tiny hole may not immediately look serious. When it appears together with recurring piles of pellet-like material, however, it becomes a much stronger reason to have the wood inspected.
6. Blistered, Uneven, or Damaged Wood
Termite damage does not always begin with a visible hole.
As termites create galleries underneath a wooden surface, the material can eventually take on an uneven, blistered, or damaged appearance. Drywood termite galleries can sometimes sit close enough to the outer surface of wood to create visible blistering.
Homeowners may notice:
- Raised or blistered sections of wood
- Areas that seem unusually thin
- Wood that breaks more easily than expected
- Damage underneath trim or molding
- Unexplained deterioration around frames or flooring
Moisture and other wood-destroying organisms can create similar symptoms, so appearance alone cannot confirm termites. The important part is recognizing that an unexplained change in the wood deserves investigation instead of being dismissed as ordinary aging.
7. Visible Termite Galleries or Internal Wood Damage
Sometimes termite activity is discovered accidentally.
A baseboard comes loose. A contractor opens part of a wall. Damaged trim breaks away. Suddenly, the inside of the wood reveals channels or hollow sections that were not visible from the outside.
These internal pathways are known as galleries.
Different termite species can create different patterns. Subterranean termite feeding commonly follows the grain of the wood, while drywood termite galleries can cross the grain.
Finding galleries means termites have already been feeding within that material. The next question is no longer simply whether termite damage exists, but how far the activity extends and what type of termite is responsible.
Why the Type of Termite Matters in Miami
Recognizing the signs of termites is only the first part of the problem.
Miami homes can face different termite species, and they do not all live or behave the same way. Subterranean termites are connected to the soil and commonly produce mud tubes. Drywood termites can establish colonies entirely inside wood and often leave frass and kick-out holes behind.
Florida is also home to invasive subterranean species, including Formosan and Asian subterranean termites, with the Asian subterranean termite particularly established in South Florida.
That difference matters because the treatment needs to match the termite involved.
Spraying a visible area without knowing where the colony is located may address what you can see while leaving the actual infestation untouched.
What Should You Do If You Notice Signs of Termites?
Avoid disturbing the area more than necessary.
Take photos of anything unusual, especially:
- Wings
- Mud tubes
- Frass
- Damaged wood
- Small holes
- Visible insects
If possible, keep a sample of the wings, pellets, or insects for identification.
Most importantly, have the property properly inspected before deciding how the infestation should be treated.
Finding one warning sign does not automatically tell you how large the infestation is, where the colony is located, or which termite species is responsible. Those are the details that determine what needs to happen next.
Do Not Wait for Termite Damage to Become Obvious
Termites are much easier to overlook than a roach running across the kitchen or a rodent making noise in the attic. Much of the activity can remain inside wood, behind walls, or beneath the property while the visible surface still looks normal.
That is why noticing the early signs of termites matters.
When something around your home looks suspicious, iPest Control Inc. can inspect the property, identify the type of termite activity involved, and recommend a treatment based on what is actually happening in your home.
For subterranean termites, iPest Control Inc. offers soil treatments using trenching and rodding with perimeter protection. Localized foam and spot treatments are available for drywood termite activity. The company does not use tent fumigation and instead specializes in targeted local and soil treatments based on the property and infestation.
Catching the problem while the clues are still small can help you address the infestation before the damage becomes much harder to ignore.
Frequently Asked Questions About Signs of Termites
1. What are usually the first signs of termites in a house?
The first noticeable signs can vary depending on the termite species. Homeowners may discover discarded swarmer wings, mud tubes, drywood termite pellets, tiny kick-out holes, or changes in wooden surfaces. Some infestations remain hidden long enough that there may be very little visible evidence at first.
2. Does finding termite wings mean my house is infested?
Not necessarily. Termites can swarm outdoors near a home without establishing a colony inside it. However, finding swarmers or discarded wings indoors, particularly around windows and doors, is a good reason to have the property inspected.
3. What do drywood termite droppings look like?
Drywood termite droppings, or frass, are tiny hard pellets that can collect underneath infested wood. They are sometimes mistaken for sand, sawdust, or coffee grounds. Under magnification, the pellets have a characteristic six-sided shape.
4. Are mud tubes always a sign of termites?
Mud tubes are strongly associated with subterranean termites and are considered important evidence of their activity. However, identifying the pest and determining whether the tube represents active or previous termite activity is best done through a professional inspection.
5. What should I do if I think I found termites in my Miami home?
Document what you found and avoid relying on a surface treatment before the termite species and extent of the activity are identified. iPest Control Inc. offers termite inspections and targeted treatment options for Miami properties, including subterranean soil treatments and localized drywood termite treatments based on the conditions found during inspection.
