Booklice are common but harmless household insects. There are more than 5,000 species worldwide.  They are often mistaken as Termites or Ants. Booklice are considered simply as nuisance pest due to their presence. Booklice are commonly found in areas that are warm, dark and damp in nature. They feed on mould, mildew, fungi and various other fibers.

Management Strategies



A residual insecticide is sprayed/misted on the infested areas as well as booklice hiding and resting places.

Preventive Measures

  • Reduce moisture in the premises, preferably lower than 50% humidity, regularly ventilating the rooms.
  • Clean/discard items that harbour mould, mildew, or fungi.
  • After removing mould, mildew, and fungi, seal cracks, crevices, void, gaps, holes, and seams where booklice may live/enter.
