5. Hollowed-Out Wood
If you tap on wood and it sounds hollow or papery, or you are able to easily break through the exterior of the wood, this is a good indication that there is termite damage, as termites normally eat wood from the inside out.
Be on the lookout for blistering pieces of wood; they may be a physical indicator that termites have infested inside your home. This leaves your walls in a fragile state.
Check the sound and structural integrity of door jambs, baseboards and window sills. If they sound hollow or you can break the wood easily with your fingers, this is a good indicator that termites are present.
6. Exterior wood damage
First, termites chew through wood to consume the cellulose that gives them their main nutrients. Then, termites leave long grooves and maze-like patterns that weaken the wood structure. For a home, this is a concerning matter for the structural integrity of the walls, floors, ceilings and other regions.
Even below the surface, you may find signs of termites like hollow-sounding wood, buckling floorboards, sagging floors, and cracks in walls and ceilings.
7. Mud Tubes
Subterranean termites build underground colonies and make tunnels above ground to search for food sources. Signs of subterranean termites invading your home are often apparent through cracked or unsealed foundations.
Termites create tunnels out of a combination of mud, their feces and saliva; these tunnels are brown, dry and cylindrical. Termites can be found living in areas like the garden and worse, under the house.
Subterranean termites in search of food travel from their home underground to the surface through self-made tubes. Mud tubes are pencil thin and allow the termites to keep very specific temperature and humidity levels to help them survive.
Also, mud tubes protect the termites by hiding them from any potential predators.
