  1. Termites frass (droppings). These droppings, also called frass or poop, are wood colored. Such droppings can be found on a bed (the sign of “roof” activity), on window sills, carpet, floor.
  2. Piles of wings. The shed wings of swarmers is a true sign that the subterranean termites have entered their next phase of development. You can often found shed wings on the windowsills.
  3. Pattern in the wood. Subterranean termites eat and destroy soft wood and eat along the grain. This causes an evident and highly visible honeycomb pattern inside the wood.
  4. Subterranean termites mud tubes. The most unmistakable sign. The tube provides shelter for the foraging termites, they pass through this tunnel to work and find food and moisture for feeding. The tubes are flattened and muddy looking. Most tubes are about the width of a pen. They are most evident when they are extending over concrete foundations and other exposed surfaces.
Advice: if you have found a structure similar to mud tube, there is a way to check whether it is active or abandoned: if you want to receive evidence, that you have found exactly a mud tube made by subterranean termites, you can remove the portion of a tunnel with a screwdriver and see if there are still termites inside.

If you see an active movement inside with termites running back and forward it means, that you have a serious infestation. If the tunnel is empty, you can check it in a few days and see, whether the tube is repaired.

Warning: even if it is not repaired it does not mean, that the insects have abandoned your house for ever. It means, probably, that they have built a new tube somewhere nearby.

But there are also a number of hidden signs of termite damage in home. Pay a close attention to the following evidences:

Damaged or hollow-sounding wood. While termites lead the veiled way of life and prefer dark and secret places, they can destroy wood material from the inside, at the same time the wood external appearance stays normal.

If wood sounds hollow when tapped, it may be because termites are eating the wood from the inside out. Also, damaged wood when opened looks layered and rotten with a great number of frass.

Sounds. Performing a periodical inspection of your house, take a large screwdriver and knock it at wood sections and walls. If the wood sounds hollow, it may have been damaged with insects.

Inside the house, put a stethoscope or similar instrument to the various walls. You will not hear the termites, but once carpenter ants digging in their cells, they are producing a quiet rustling.

This produces a distinct honeycomb pattern in the wood.

It is crucial to stop subterranean termites as soon as the infestation is discovered.

Also, one can discover deformed furniture, ceiling and floor joists, stairs and other wooden structures: termites eat the wood from the inside, that is why it sound hollow. Rotten and eaten through wood could be deformed.

Smells. Termites do not produce any smells. One can smell just rotten wood and a smell of mold in damp places of a house.
