Fermosan Termites

Facts, Identification & Control

SCIENTIFIC NAME

Coptotermed formosanus

IMPERIUM'S INSPECTION FOR FORMOSAN TERMITES

  • Our inspection for Formosan Termites is carried out in the same manner as for other subterranean termites, along with looking for colonies that do not maintain contact with soil.
  • These subterranean termites often build shelter tubes or extend carton material from their nest in areas that are well above ground level.

FORMOSAN TERMITE CONSUMPTION

  • Formosan termites consume a greater variety of woods and other cellulose-containing material than other termite species.
  • Appear to have a greater tolerance to soil insecticides.
  • Formosan termites are a much greater threat to structures than other subterranean termites.
  • Can rapidly invade and damage structures.

FORMOSAN TERMITE COLONIES

  • Colonies usually consist of several hundred thousand termites, and colonies of more than a million are not unusual.
  • A large colony size is possible because of their great reproductive potential. A formosan queen can produce up to 1000 eggs per day, when new nests and foraging areas are established, the population can rapidly expand.

WHY ARE FERMOSAN TERMITES DISTINCT AND DIFFICULT?

  • Formosan termite does not need constant contact with soil as long as there is a moisture supply.
  • Can live entirely within walls of a structure or in other spaces, although they usually establish soil contact using mudtubes, as do other subterranean termites.
  • When evading a structure there is often more extensive tube and tunnel building.
  • Form carton nests made of masticared (chewed) wood and saliva.
  • These nests may be several feet in diameter, and are sometimes located in the soil where workers simply forage for wood (or other cellulose) as do other subterranean termites.
  • The entire nest may be housed within the wall of a structure or under fixtures within the structure.

SIGNS OF FORMOSAN INFESTATION

  • A common sign of infestation is the appearance of swarming alates.
  • Swarming flights begin from May to June and last until July or August.
  • They occur on humid, still evenings between dusk ad midnight (alates are attracted to lights.)
  • Finding a carton nest within the structure is a sure sign of a Formosan termite infestation. Other subterranean termites do not construct this type of nest.
