What technique can be used to detect termites in hidden areas?

The technique of using acoustic detection devices or infrared cameras is effective in locating termites in hidden areas because these tools can identify signs of termite activity without the need for direct visual access. Acoustic detection devices work by picking up the sounds made by termites as they feed on wood, allowing pest control professionals to locate nests that are not visible to the naked eye. Infrared cameras can detect temperature differences associated with termite activity, as the presence of termites can lead to localized changes in heat due to their metabolism.

In contrast, other techniques may not be as effective for hidden areas. Visual inspection with a magnifying glass might help identify visible signs of termites but is limited to areas that are accessible and visible. Regular fumigation services are preventative or treatment measures for established infestations, not detection methods. Using chemical attractants might draw termites to a location but does not aid in locating them in hidden areas effectively.
