Woodlice Control Products

Some sprays and powders provide fast knockdown of woodlice you can see, while others are applied to cracks, crevices and entry points to leave a residual treatment that helps reduce repeat activity over time. Focus on damp hotspots (around doors, air bricks, pipework and under sinks) and treat only the areas listed on the label. For best results, combine treatment with reducing moisture and improving ventilation, as woodlice thrive in damp conditions. Always read the label and use as directed, keeping children and pets away until treated areas are dry/secure.

Many of our woodlice control products are non-toxic and safe to use around pets and children. However, it's important to follow safety instructions when using any product including sprays and powders to ensure proper usage in homes with children or pets. If considering sprays, we recommend starting with non-toxic options.

To prevent woodlice from entering your home, reduce dampness by fixing leaks and using dehumidifiers in humid areas like basements. Seal cracks and gaps around windows, doors, and foundations. Keeping your home dry and well-ventilated is key to discouraging woodlice.

It depends on the product. Some sprays can give fast knockdown of woodlice you can see, so you may notice a difference quickly. Residual treatments (including physical-action dusts like diatomaceous earth, when kept dry) can help reduce repeat activity around entry points and damp hotspots over time. Repellents and deterrents may take longer and work best alongside proofing—seal gaps, improve ventilation and address damp to make the area less attractive. Always follow the label for use and expected performance.
