Hi recently i notice tiny moving black dots on my wall, they usually stay very still and they move when i shine my torchlight on them. Is this a pest?

Booklouse

Dear Doesnt matter,
This is a nicely detailed photo of a Booklouse.  Booklice in the family Liposcelididae are pictured on BugGuide.  According to Charles Hogue in Insects of the Los Angeles Basin:  “Although it is a contributor to the allergens found in house dust and its feeding may do minor damage to book bindings and paper, the presence of the Book Louse is usually no more than an annoyance.”

  1. This is not a springtail, but a type of barklouse. I have noticed in the past that wingless or nymphal barklice can look a lot like globular springtails, but if you look closely at the photos you can see the reduced wings or wingbuds in this individual.

    I would guess that this is probably (but not definitely) Psyllipsocus ramburii (http://bugguide.net/node/view/830096) which is a widespread domestic barklouse species. Another possibility is a nymph of Dorypteryx domestica, which you’ve had an individual of on this site before (https://www.whatsthatbug.com/2008/11/13/booklouse-2/). Both of these belong to the family Psyllipsocidae, which I can confirm from personal observations do jump.
