## Description

Pest Expert Formula 'C+' Advanced Bed Bug Killer Spray is a fast-acting bed bug spray with a long-lasting residual that maintains control. Pest Expert Formula 'C+' is a highly-effective bed bug killer spray that delivers a rapid knockdown and helps maintain bed bug 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 bed bug 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+' Advanced is water-based so is safe for direct application to frames, mattresses, bedding and carpets and will not cause them any damage. Formula 'C+' is low-odour and free from solvents, so it is perfectly suitable for bed bug treatment in all contexts, including hotels, hospitals and care homes, and households with children and/or pets, provided they are kept out of the area being treated until all surfaces are dry (2-3 hours). For particularly heavy infestations, several applications may be necessary. A trigger hose sprayer is also included for a professional application of Formula C+ Spray (one per order).
