Detection

Because subterranean termites work inside wood, most homeowners are not aware of a problem until it’s too late. Other species, such as the drywood variety, leave their sawdust-like feces near infested areas. Subterranean termite droppings are not so easy to spot, making it even tougher to discover an infestation before the damage becomes severe.

What Do Subterranean Termite Feces Look Like?

Subterranean termite droppings, also called frass, are small, rounded pellets made from timber. This species typically leaves its waste inside wood. Prying open infested lumber will reveal snaking tunnels coated with subterranean termite frass.

The only time residents usually notice the pests’ feces is when they spot shelter tubes. These insects build pencil-sized, mud-colored tunnels on walls, foundations, and floors to travel without facing the open air. They use subterranean termite frass, mud, and saliva to make their tubes.

Are Subterranean Termite Droppings Dangerous?

Frass won’t spread diseases or parasites to residents. Although the pests waste isn’t harmful, their tunneling habits can be dangerous. Termite damage to support beams may make affected parts of the house unstable, so it’s important to treat an infestation.

Preventing Subterranean Termites

Termites get into homes through timber that touches the soil.The pests prefer dampwood, so excess water around foundations attracts them.

Modifying houses to repel termites may prevent future problems, but it does little to fix an active infestation. Homeowners who notice subterranean termite droppings or other signs of these insects can contact Western Pest Services for reliable control.
