Termites are known as “silent destroyers” because they can chew through wood, flooring, and even wallpaper undetected for years. By the time most homeowners notice them, significant structural damage has already occurred. Recognizing the early warning signs of a termite infestation can save you thousands of dollars in repairs. Here are the 5 most critical signs to watch out for.

1. Mud Tubes on Walls and Foundations                                                                                                             

Subterranean termites need moisture to survive and build pencil-thin mud tubes, also known as shelter tubes, to travel between their underground colonies and a food source such as your home. These tubes are often found along foundation walls, exterior walls, baseboards, crawl spaces, and behind drywall. Spotting fresh termite mud tubes can be a warning sign of an active subterranean termite infestation and should be inspected promptly to help prevent costly structural damage.

 2. Hollow or Damaged Wood

Termites often consume wood from the inside out, leaving the outer surface looking intact while weakening the structure underneath. If door frames, window sills, wooden beams, or other wood surfaces sound hollow or papery when tapped, it could indicate hidden termite activity. As an infestation progresses, termites can cause wood to weaken, floors to sag, and damaged timber to crumble easily. If you notice these warning signs, a professional termite inspection can help identify the extent of the damage.

During termite swarming season, winged reproductive termites, known as swarmers, leave established colonies to mate and start new colonies. After landing, they quickly shed their wings. Finding piles of small, translucent termite wings on window sills, doorways, floors, or spiderwebs can be a strong indication of an active termite infestation nearby. If you notice discarded wings inside your home, scheduling a professional termite inspection can help determine whether a mature colony is present.
