Book Lice

Booklice

These fast moving, minute, cream-coloured or light brown insects, only 1mm long, occur in small numbers in many premises. There are several species, known collectively as Psocids. All have soft bodies. Very few species have wings.

Sticky, pearl-coloured eggs are cemented to damp surfaces and, instead of a larval stage, the insect matures through four recognisable nymph stages, taking about a fortnight in total.

The adult booklice are believed to feed on microscopic moulds that grow on the glue of book-bindings or on damp cardboard, damp food (especially cereals) or on the surfaces of plaster, leather or wood inside buildings.

They can occur in huge numbers in new properties where the plaster is still damp. One species of booklouse produces an audible tapping noise by banging its abdomen against paper or wood.

How we can help
  • We treat all rooms which have Booklice in by using fogging or residual insecticide sprays.
  • We will only carry out a partial treatment (one of 3 rooms for example) at the request of the client, but partial treatments are not successful and not recommended.
Before our visit
  • The property must be vacuumed and cleaned thoroughly throughout. All items should be taken out of food cupboards. If infested, the product should be thrown away. Wipe away any visible mould on cupboard surfaces thoroughly ventilate and dry the area where they are found.
  • All items on the floor such as shoes, bags etc. should be taken off the floor especially at floor and wall junctions.
During our visit

You should be out of the property during our treatment and until the insecticide is dry, normally about 3 hours dependent on temperature.

After our visit
  • Do not sweep, brush, mop, vacuum, or clean the area that has been sprayed for at least 14 days, this is to let the insecticide work through the insects' life cycle which we are trying to break.
  • If after 14 days there is still activity then a second treatment may be required.
