It kills beetles on contact, prevents lifecycle progression, and provides up to 12 weeks of residual protection. This water-based, low-odour spray covers 100m² per 2L pack, is safe for use around children and pets when used as directed, and leaves no stains—ideal for both home and business environments. ## Description Pest Expert Formula 'C+' is a fast-acting insecticide that that can be applied to carpets and soft furnishings, killing carpet beetles on contact and leaving behind an insecticidal residue that is effective for up to 12 weeks for long-lasting control. 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 carpet beetle 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. Pest Expert Formula 'C+' is a water-based product that is both low-odour and solvent free, so it is safe to use in households with animals and/or young children as long as directions for use are followed and they are kept out of the treated area until surfaces are dry (approx 3 hours). Formula 'C+' should not damage any items that would not be damaged by water, although we recommend it is used with caution on particularly delicate fabrics. Heavy carpet moth infestations may require a second treatment. To carry out a carpet beetle treatment using Formula 'C+', lightly spray the carpet, applying more product to specific areas of damage. A heavier application should also be administered around the edges of the room, which should save you the trouble of having to lift and treat beneath the edges of the carpet. Leave the room and allow around 3-4 hours for surfaces to dry before returning. Avoid vacuuming for as long as possible after treatment as this will remove the insecticidal residue and reduce efficacy. ## Features - ✅ THE STRONGEST CARPET BEETLE SPRAY ON THE MARKET – Our latest innovative formulation contains three powerful active ingredients making it unparalleled in its ability to eradicate carpet beetle infestations from the home or business. - ✅ NEWLY DEVELOPED FORMULATION – Now containing three powerful active ingredients, including an Insect Growth Regulator, Formula C+ kills carpet beetles on contact and halts the progression of the carpet beetle 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 carpet beetles 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 – 2 x Formula C+ now covers 100 square meters in a single application making it the most cost-effective carpet beetle spray on the market. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B013JVIZZS | | Best Sellers Rank | 62,124 in Garden ( See Top 100 in Garden ) 319 in Bed Bug, Flea & Mite Control | | Brand Name | Pest Expert | | Customer Reviews | 4.4 4.4 out of 5 stars (211) | | 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 Formula 'C' Carpet Beetle Killer Spray 2 x 1Ltr (HSE approved and tested - professional strength product) - Image 1](https://m.media-amazon.com/images/I/41hsNDGZ+-S.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/56182609-pest-expert-formula-c-carpet-beetle-killer-spray-2-x](https://www.desertcart.hk/products/56182609-pest-expert-formula-c-carpet-beetle-killer-spray-2-x) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-08-17*
