What should I do if I find 3 termites at home? My home is in Changzhou.

Carefully find the ant path and buy a bottle of powder spray, which is very effective. If you find the ant path they go in and out, spray it often and it will soon be eliminated. My family used to be like this. If it's the first floor, don't pile a lot of things in a room. Keep the room ventilated and not wet.
