The answer to 'termite trails' is that termite trails, also known as mud tubes, are a common sign of an active termite infestation. Termites build these mud tubes to travel from their nest to food sources, such as the wooden parts of your home. Seeing termite trails is a clear indication that you have a termite problem that needs to be addressed.
Termite trails are typically made of a mixture of mud, saliva, and fecal matter. They are usually about the width of a pencil and can be found on the exterior of your home, crawling up the foundation or along tree branches. If you see these trails, it's important to take action quickly to prevent further damage to your home.
