Abstract
A covering for soft furnishing is impregnated with an insecticide, such as permethrin. The concentration of permethrin is sufficient to kill house dust mites and deter larger insects such as fleas and ticks. The insecticide is released from the covering over an operational period so as to encourage the absorption of the insecticide into surrounding soft furnishings. The covering is manufactured from machined fabric, such as knitted voile, having interstices sufficiently small to reduce the rate of insecticide release over the operational period.
