Rentokil Insectrol Insect Killer is a highly effective insect spray designed to kill and control crawling insects in and around the home. The long residual activity means it carries on working in cracks and crevices long after spraying. Ideal for controlling cockroaches, ants, fleas, bedbugs, beetles, silverfish, woodlice, carpet moths, carpet beetles and other insect and non-insect pests. This can be sprayed on surfaces and also (carefully) over fabrics and bedding.
