Termites are problematic pests that silently destroy homes, often without making any sounds, and become visible only after it is too late, having already infested expensive furniture. Termites do not leave an easily noticeable trail. By the time most homeowners realize something is wrong, an entire colony has been working for months or even years.
What makes termites eerie is how ordinary their entry points are. A small crack in the foundation, a wooden door frame near soil, or a dark, damp corner behind a piece of furniture are common entryways. While none of these areas feels concerning on their own, they are precisely where termites attack.
The good news is that termites do leave signs if you know what to look for. Recognizing these signs can help you detect an early termite infestation. Here are some areas where termites tend to attack first and common signs to spot an infestation early.
Wood Near the Foundation Is Always the First Target
Subterranean termites create mud tubes to travel from the soil to their food source, which may be your home. Any wood touching or located close to the soil, such as door frames and wooden beams near the base of walls, is where they begin. If you have places outside your home where wood touches the soil, especially in moist, shady spots, look there first for evidence of termite activity.
Mud Tubes Along Walls and Foundations Are a Clear Red Flag
Subterranean termites, the most destructive species, build mud tubes to provide moisture while traveling between their colony and food source. These mud tubes are most often found near the home's foundation. These pencil-thin tunnels retain moisture and protect termites from drying out. They are easily overlooked because they tend to appear in low, dark, or hidden corners, behind furniture, along basement walls, or in crawl spaces. When you run your finger through a suspicious space and it crumbles into soil and debris, you may need professional help to eliminate the termites.
Hollow-Sounding Wood
One of the most common signs of a termite infestation is something you hear rather than see. Termites eat wood from the inside out, leaving only a thin outer layer. Touching and knocking on damaged areas may produce a hollow or papery sound because part or all of the timber inside has been eaten away. This is particularly common in wooden flooring, internal walls, and door frames. When termites eat through wood in search of cellulose, they cause the wood to warp, which can make opening and closing doors and windows difficult.
Discarded Wings Near Windows and Doors
Termite swarmers, or their discarded wings near windowsills and doors, are often the first and only visible sign of a termite problem on the outside. Winged termites invade homes in the springtime, and the rest of the colony follows them. After they settle, they shed their wings, leaving behind small, fish-scale-like piles near light sources, window ledges, or caught in cobwebs.
