In most cases, subterranean termites must be in contact with soil to receive the moisture they need to survive. However, the Formosan termite – an exotic species of subterranean termite – is an exception to the rule. Formosan termites can build aboveground nests, called cartons, inside walls and attics when there is enough moisture in the wood.
Typically, Formosan termite nests are made from termite excrement, chewed wood and soil. Carton nests can be found between walls, under sinks and in attics.
Are There Termites in My Attic?
If you are wondering how to detect termites in the attic, you should know that it takes a great deal of training to reliably detect termite activity. Termites can hide behind the walls of a home and leave few signs of their presence – or signs can be misidentified as water damage.
Licensed termite experts are trained to recognize signs of termite activity, including damaged wood and discolored or sagging drywall. Some inspectors have access to equipment, such as infrared cameras and moisture meters, which can help detect activity and areas prone to infestation.
Annual termite inspections should be a regular task on your list of home maintenance chores if you live in an area where termites are particularly active. In the ideal moist and warm climate, Formosan termites can significantly damage a home in less than two years. Early detection and preventative treatment methods are crucial to protect your home.
Treating Formosan Termites in the Attic
Formosan termites typically enter a home from the ground. The best way to prevent infestations is to use termiticide treatments or underground bait systems to help control the colony before it reaches the wood in your house.
If Formosan termites infest your attic, talk to your termite technician about potential treatment options, including fumigation and direct wood treatment.
