How do booklice look like? On a few occasions, a number of my family and friends have frantically rang me on my mobile, looking for an answer to this question: “Do you know what are those tiny black dots on the walls? They move! And there are lots of them!”
Just a tiny squash using one of your fingers is enough to wipe it away. Yet these tiny black dots, they come in hundreds and hundreds of them… sticking themselves to the bathroom walls, the bedroom walls or even inside the wardrobes.
You could not possibly squash them all!
Do booklice really feed on books?
Booklice? Yes, this is certainly interesting to know, “Are booklice caused by books?” This is in fact, the opposite of what its name suggests; a booklice is not caused by having books around in the home or office.
How the presence of booklice come across is because, they are attracted to places with a high humidity. The high humidity in a room allows moisture, mold and mildew to grow very quickly. And for the booklice, they feed on these mold and mildew to survive. It is food for these pests.
So perhaps if your books start to grow a lot of mold on them, they would then very likely attract booklice to feed on the mold on the books. But for a booklice itself, it does not come from the books. See the difference?
No. Booklice are not biting pests, as opposed to Bird Mites. Booklice feed purely on the mold and mildew at places with high moisture.
Well it doesn’t help that in Singapore we experience a tropical climate all the time, leading to a warm and moist environment at homes and in the offices. These weather conditions make it extra favorable for booklice to thrive on.
Booklice are soft and have two pairs of wings with long antennae. They tend to hop around and you may find these tiny dots appearing on wet and moist spaces including crawl spaces, books, tiles and basement. In fact, there are over 3,000 species of book lice and they are also known as Psocids. They feed on fungi and algae found on books, papers or painting that has high humidity. Though these tiny pests do not have a long life span and typically survive a few months, it is important to lookout for their signs and presence as their eggs that lay within cracks and crevices can result in a breeding problem.
