Professional Booklice Control Services in the UK

Booklice are often mistaken for bedbug nymphs due to their tiny size and pale appearance — but they are very different pests. Booklice belong to the order Psocoptera and are not true lice. Unlike bedbugs, they do not bite and do not feed on blood. Instead, they feed on mould, fungi, and starchy residues found in damp indoor environments.

Why Booklice Appear Indoors

The key driver behind a booklice problem is nearly always humidity and moisture. They thrive where mould and organic build-up can form — which is why infestations often show up in cupboards, around damp plaster, or behind wallpaper.

Where Booklice Are Commonly Found

• Food cupboards, pantries, and wooden shelving
• Bookshelves (feeding on microscopic mould in paper, glue, and bindings)
• Behind wallpaper, skirting, and damp wall areas
• Poorly ventilated rooms with condensation or mould growth

Do Booklice Cause Damage?

Although booklice are not dangerous, they can become a nuisance in large numbers. They may contribute to:

• Damage to books and paper materials (by feeding on mould present on surfaces)
• Contamination concerns in dried food products such as flour, cereals, and powdered goods
• Persistent infestations if humidity and mould are not addressed

How We Help

At Shire Pest Solutions, we focus on both the visible insects and the underlying cause. If booklice keep appearing, it usually means moisture levels are still too high. We can assess the environment, advise on humidity reduction, and apply targeted treatments when required.

Prevention Tips That Actually Work

• Reduce indoor humidity (dehumidifiers are often the quickest win)
• Improve airflow and ventilation in cupboards and storage areas
• Fix leaks, damp patches, and condensation issues
• Remove mould and organic residue thoroughly
• Store dried foods in airtight containers
