Very tiny white bugs, also known as psocids or booklice, are small insects that feed on mold and fungi. They range in size from 1mm to 5mm in length and are usually cream-colored. Psocids can be found all over the world and thrive in damp, dark places such as bathrooms, kitchens, basements, attics and behind walls. These bugs often enter homes through open windows or cracks around doors. Although they do not bite or cause any harm to humans directly, they can be annoying when they appear in large numbers indoors. To control an infestation of very tiny white bugs you should first identify where they are entering your house from and fix those entry points if possible. You should then clean away any signs of moisture (such as wet clothing) that could attract them inside the home. Finally using a vacuum cleaner will help get rid of any existing pests before using insecticides to prevent further invasions.
