Maderlim Woodworm Killer 25L: the professional insecticide for large-scale wood treatments
Maderlim Woodworm Killer 25L is a solvent-based liquid insecticide with dual preventive and curative action against the main xylophagous insects: common furniture beetle, house longhorn beetle, termites, and wood moths. Its professional 25-liter format makes it the most cost-effective option for carpenters, restorers, and pest control companies who treat beams, floor structures, and entire structures.
💡 Key advantage: its solvent base penetrates deep into the wood, far more than water-based woodworm killers, ensuring that the treatment reaches larvae lodged inside. At €6.20/liter, it is one of the most economical professional treatments on the market.
