There are some very specific signs of a termite infestation. This includes:
Termite droppings typically look like tiny, rigid wood-colored pellets.
Termite mud tubes are very distinct. They are typically on the exterior of the surface and provide protection for termites.
Usually, their wings are all the same size and look like slender fish scales. These are usually the first sign of a termite problem. Swarming termites, or swarmers, are attracted to light and often found near light fixtures
Tapping wood along the walls, baseboards, and windowsills with a screwdriver will sound hollow. If the area is extremely damaged, you may break through it and see termite workers inside.
