Textile pests, as the name refers, are more associated with textiles such as cotton, wool, silk and bird nesting materials.
In domestic properties they are more associated with high quality carpets that contain a large percentage of cotton or wool fibres. The damage tends to be underneath items of furniture that are difficult to move on a regular basis when vacuuming.
Infestations can also migrate down into the house where birds have been nesting in the eaves of a property. In this case the bird nesting material will need to be removed and a residual insecticide applied and backed up by an insecticidal treatment to carpets and possibly wardrobes.
