Ronseal Woodworm Killer

The Ronseal Woodworm Killer is a professional-strength treatment designed to eliminate wood-boring insects from interior timber. This effective woodworm treatment not only kills existing infestations but provides long-term protection to prevent future woodworm problems. It offers tradespeople and property owners a reliable solution for treating affected joists, floorboards, rafters and other interior woodwork. Suitable for use on any interior wood, this treatment penetrates deep into timber to target woodworm larvae and adults. The formula dries to a clear matt finish within two hours, making it ideal for professionals working to tight schedules. Once fully dry, the treated surface can be stained, varnished or painted over, allowing you to complete decorative finishes without compromising the protective treatment beneath. With coverage of up to 10 square metres per litre, this 5-litre container provides sufficient treatment for larger restoration projects or multiple smaller jobs. The brush application method ensures controlled, accurate coverage on beams, structural timber and furniture affected by wood-boring insects.
