Where to look for signs of infestation with drywood termites? How to inspect a house?

Where to look for signs of termites?
Termites live in dry wood out of contact with ground as they need very little moisture. All these termites have wings and settle in a tree from the air above ground level.
They build nests in:
- timber frame;
- in the casing;
- window frames;
- in trees;
- in the attic;
- in the ceilings and floors;
- in any wooden furniture and other wooden items.
A pair of winged termites appear in a wooden element through a crack and make tunnel into the core where they build a nest. To see them, except for the moment when they move to another wooded element, is almost impossible.Their presence can be notice quite difficult, for example by solids of digested wood. Therefore, it’s important to examine everything properly especially places where they are likely to appear.

Warm temperatures and heavy rains instigate swarms.
Since termites are usually hidden from sight, the type of infection is easier to be identified by winged insects.
Drywood termite’s frass, droppings and pellets
