Wider tubes indicate a more serious infestation. Remember, infestations develop in soil. The termites enter the building through structural wood or foundation walls adjacent to the soil. In the case where houses are built partly or completely on slabs, infestation is through expansion joints, cracks and utility and sewer openings. If damage is found, there is no great hurry to apply control measures.
Termites work slowly, and a few weeks delay is of little consequence.
This is done by laying down a chemical barrier to eliminate all possible points of entry. In view of the rather elaborate equipment required and the complicated nature of the process, it is strongly suggested that the homeowner consult a professional pest control service. There is no need to become frightened or unduly alarmed if you learn that termites may be attacking your home. These insects work slowly, and your house will not be ruined or collapse overnight. Take your time.
