Barrettine Premier Woodworm Killer, formulated with permethrin, offers a quick and efficient solution for eliminating woodworm and their larvae. It is perfect for treating ceiling and floor joists, floorboards, wooden beams, furniture, doors, and more.

Signs of insect infestation include small round holes on the timber’s surface, often accompanied by gritty bore-dust. These holes are commonly found near joints or on the undersides and backs of furniture. While the holes indicate beetles have emerged, the larvae are likely still present within the wood.
