Termites can be difficult to identify, but there are some signs that you may have them in your home. Inspecting the windowsills for evidence of subterranean activity is a good place to start.

Look for fecal pellets, mud tunnels and activity near the base of the window frame. If you think you have termites, call a professional to investigate.

Scattered Wings on wood sills, frames, or other surfaces

One of the signs of a termite infestation is when you see wings scattered on your window sills. Termites will swarm as they leave their current colonies to find new homes. They will mate and bore themselves into the wooden structure to lay eggs and establish a new colony.

When termites swarm, their wings break off and scatter as they take flight. If you see what looks like wings on your window sill or other surfaces, you likely have an infestation of termites. Keep in mind that no other animal has wings that resemble a termite.

Tiny Holes (as Termite tunnels in foundation, ceiling, floor, roof, yard, and other termite activity areas)

Window sills are common for termites to assemble and build their colonies. If you notice tiny holes in your window sills, you likely have a mild infestation of termites.

The termites create these holes as they exit and enter the colony. Another sign of an active infestation is the presence of pinholes on surfaces near the windows.

Sound Hollow in Termite Damage Places

The next sign of termites is when you tap on the window sill and hear a hollow sound. The termites have eaten away at the wood, making it soft and brittle. It is caused by high moisture levels, creating an ideal environment for termites to thrive.

If you’re unsure whether or not there are termites in your window sills, you can poke the bump with a pin. If powder comes out of the swollen part of the wood, then termites are present.

Termite Dust (Drywood Termite Frass, Termite excrement, Frass Pile, or Termite Frass Pellets)

When termites are present in a structure, they can cause extensive damage. Not only do they eat the wood, but they also create tunnels and tubes made of their feces. These tubes and tunnels allow them to move from one place to another without being seen.

As a result, it’s important to be aware of the signs of termites so that you can address the issue as soon as possible.

Termite droppings are tiny black pepper-like particles that you will find around windowsills and on the floor. They may also be present on wooden beams or furniture.

It is important to note that termite droppings do not look like sawdust, which can often be confused as a sign of an infestation. 

Mud Tubes (Shelter Tubes or Mud walls)

Mud tubes are often the first sign of a termite infestation. They are made of mud and help the termites carry food back to the colony. The tunnels also block outside air and retain moisture, which is essential for the termites’ survival.

If you see any evidence of mud tubes or tunnels on your window sills, it’s important to contact a professional immediately.

Chewing Sounds of Drywood Termites Swarmers from Inside the Home

The chewing sound is the telltale sign of termites. They make this noise as they eat the wood in your home. Termites might eat the wood from inside a wooden piece or structure, or they might swarm inside to invade your home.

Once they’ve infested, getting rid of them cannot be easy. Don’t ignore these signs – take action and get rid of the termites before they do damage to your home!

Presence of both dead and active termites inside home and exterior sources

Termites can be difficult to detect, especially if they are only in the early stages of infestation. However, there are some signs that you can look out for. In particular, termites will leave clues when infesting your home.

Common signs of a termite infestation include dead and live termites on window sills and around your home, exit holes (usually during mating season), and feathers breaking off and gathering around window sills.

Although termites usually come from the soil, they can also enter homes through wooden components such as doors and window frames. Termites often attract light sources, which is why you may see dead termites around your window sill.

It’s important to remember that dead termites do not always mean you have an infestation; however, it’s best to consult a professional if you have any concerns.
