How can you recognise booklice?
Booklice are not human lice or dust mites. They favour damp places and may feed on mould. Removing the visible insects alone will not solve an ongoing moisture problem.
Tiny insects in damp areas
Look around window frames, skirting boards, wallpaper, paper storage and humid cupboards.
They return after cleaning
Recurring activity in the same cool or poorly ventilated spot suggests the conditions still suit them.
Moisture clues
Condensation, a musty smell, staining or a leak may point to the underlying issue.
Species and sources
Why do booklice appear?
Condensation
Cold window frames and exterior walls may stay damp enough for mould and booklice.
Leaks or building moisture
Water behind skirting boards, in cupboards or in new building materials can create a hidden habitat.
Damp food or paper
Cardboard, books and stored dry goods can also become affected when moisture reaches them.
What to do now
Get clarity on your situation
Take a clear photo and note exactly where you found them. Check for condensation, leaks and mould; ventilate and dry the area. Keep a specimen if identification is uncertain, and do not seal over an unexplained leak.

How Eversor helps
We start with the species and where the activity begins. Then we explain our work and the practical steps you can take.
Identify the insect and location
We assess your photo or inspect the insects on site and map where they are concentrated.
Find the moisture issue
We check visible signs of condensation, leaks and poor ventilation. Structural repairs may require a building specialist.
Set out a practical plan
We explain drying, cleaning and repair steps, and whether any additional treatment would help. You deal with Eversor directly.
Cost
Know the work and price beforehand
The cost depends on how widespread the problem is and what investigation is needed. We explain Eversor’s work before you agree; specialist building repairs are separate. Send a photo and location for a useful first assessment.
FAQs
Frequently asked questions about booklice and psocids
Are booklice the same as dust mites?
No. Booklice are small visible insects; dust mites are different animals that are difficult to see. Booklice do not live on people.
Can I deal with them myself?
You can vacuum visible insects and dry the area. Find and resolve the source of moisture. If they keep returning, investigate that source before using sprays.
I found them in a bedroom. Is the bed the source?
Not necessarily. Check window frames, outside walls, wallpaper and stored items. A clear photo helps distinguish them from other insects.
When should I contact Eversor?
When they persist, occur in several rooms or you cannot identify the moisture source. We first check what is present and what help is useful.
