Spots On The Wall?  Understanding Booklice Control

Posted by GreenSIR 10/06/2020 0 Comment(s) Cleaning,



Humid weather will bring moulds, walls, anchor lines, crevices etc. at our home will start to have noulds emerging. The most common scenario is the paper products such as books, magazines, paper boxes etc.  became damp and got moulds on them. Apart from having stains, the moulds will bring Booklice (Psocids) into your home as well.



Weather has been getting humid, it is very common to see some sesame-seed-shaped insects crawling on the ceilings and walls. 

Those small insects are booklice, one of the most common household insects in Hong Kong. You can identify them by the characteristics below :
  • 1-2 mm in length, which are smaller than ants
  • In a range of colors from gray to brown
  • Prefer to grow in warm, moist and dark environments
  • Primarily feed on mould and fungi
  • Do not bite
Common spots of finding booklice include wallpaper, wall, ceiling, books, papers, wood furniture, and plotted plants.
Once finding booklices, usually we will soon deploy the pesticide spray or fumigator products. But how about solving the problem without chemical pesticides? It can start from the root of pests. Food source is the only reason that pests will stay at your home, therefore, the problem can be solved by non-chemical methods.
