Beyond mud tubes, check for other indicators of termite presence throughout your home. Pay attention to areas where wood meets the ground or is in contact with soil, as these are prime entry points for termites.
Inspect wooden structures for blistering or warping, which can occur when termites tunnel close to the surface. Additionally, listen for faint clicking sounds coming from the walls, which may be the sound of termites chewing or communicating.
