## Overview

Formula ‘C+’ Silverfish Killer Spray and Powder is a professional-strength pest control solution designed for both home and business use. With a fast-acting formula that includes an Insect Growth Regulator, it effectively eliminates silverfish and prevents future infestations. The non-staining, low-odor spray is easy to apply on various surfaces, while the powder offers double the coverage compared to competitors, making it a cost-effective choice for long-lasting pest control.

## Description

Formula 'C+' is a fast-acting insecticidal silverfish spray with a rapid knockdown effect. 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 silverfish 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). Pest Expert Formula 'P' Silverfish Powder is a highly effective Silverfish killer suitable for Silverfish control in hard to reach areas and around electrical cabling. As silverfish are mainly active at night time, the best measures are prevention not only cure, Formula P contains the active permethrin, a broad spectrum insecticide, which will maintain its killing power for up to 12 weeks, ensuring that night or day your silverfish infestation will be in rapid decline. Both the spray and powder can be applied to carets and other surfaces for effective long-term control effective control of silverfish. As silverfish feed not only on food debris but also on starches and gums used to bind books and wood, they can often be found in homes, particularly in areas where using a water based spray would not be suitable such as around electrical cabling, electrical equipment and freshly laid woodwork.
