Safe for use on carpets and furniture, it’s designed for effective, low-odour woodlouse control in homes and businesses. ## Description Pest Expert Formula 'C+' Woodlouse Spray is our best-selling product for eradicating Woodlice infestations and the most powerful woodlice spray available to the amateur market. Formula 'C+' is a fast-acting woodlouse killer that enables you to carry out an effective woodlice treatment to carpets, units, cupboards, rugs and alighting surfaces, with a long-lasting residual that maintains woodlice control for up to 12 weeks. Formula 'C+' is safe for direct application to rugs and carpets as it is water-based so will not cause them any damage. Our latest innovative formulation incorporates two additional active ingredients. The first is pyriproxyfen, a ground-breaking insect growth regulator that halts the progression of the lifecycle development from juvenile to adult, resulting in the inability for the woodlice to reproduce. The second is the addition of chrysanthemum cinerariaefolium extract, a natural pyrethrum, which when combined with cypermethrin (0.1%) has a synergistic effect, helping to deliver an even faster knockdown and longer-lasting residual for ongoing control of all lifecycle stages. Formula 'C+' is low-odour and free from solvents, so it is perfectly suitable for use in homes with children and/or pets, provided they are kept out of the area being treated until all surfaces are dry (2-3 hours). ## Features - ✅ THE STRONGEST WOODLICE SPRAY ON THE MARKET – Our latest innovative formulation contains three powerful active ingredients making it unparalleled in its ability to eradicate woodlouse infestations from the home or business. - ✅ NEWLY DEVELOPED FORMULATION – Now containing three powerful active ingredients, including an Insect Growth Regulator, Formula C+ kills woodlice on contact and halts the progression of the woodlice lifecycle development, resulting in no new numbers. - ✅ FAST ACTING AND LONG LASTING – The three potent active ingredients work in a synergistic way helping to deliver an even faster and more widespread knockdown of woodlice and leaves an insecticidal residue that continues to protect for up to 12 weeks. - ✅ NON-STAINING AND LOW-ODOUR – Formula C+ is a ready-to-use, water-based spray so can be applied directly to any surface and furniture without causing any damage or nasty lingering smells. - ✅ INCREASED COVERAGE – Formula C+ now covers 100 square meters in a single application making it the most cost-effective woodlouse spray on the market. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0144ML67A | | Best Sellers Rank | 80,072 in Garden ( See Top 100 in Garden ) 717 in Indoor Multi-Insect Control | | Brand Name | Pest Expert | | Country of Origin | United Kingdom | | Customer Reviews | 4.2 4.2 out of 5 stars (264) | | Item Form | Spray | | Liquid Volume | 1000 Millilitres | | Manufacturer | Pest Expert | | Specification Met | USDA | | Target Species | Insects | ## Product Details - **Brand:** Pest Expert - **Item form:** Spray - **Liquid volume:** 1000 Millilitres - **Specification met:** USDA - **Target species:** Insects ## Images ![Pest Expert Woodlice Killer Spray Treatment 2 x 1Ltr - Formula ‘C+’ Advanced Max Strength Insect Killer Spray, Fast-Acting & Long-Lasting Control - Professional Strength Approved for Amateur Use - Image 1](https://m.media-amazon.com/images/I/41hsNDGZ+-S.jpg) ## Questions & Answers **Q: Is it harmful to dogs?** A: Yes, this product is harmful to dogs.
