## Overview

Pest Expert Formula C+ is a professional-grade, 5L cockroach spray featuring a triple-active ingredient formula that kills instantly and prevents future infestations by disrupting the cockroach lifecycle.

## Description

Pest Expert Formula 'C+' Cockroach Spray is a fast-acting insecticide with a long-lasting residual that maintains cockroach control. Pest Expert Formula 'C+' is a highly-effective insecticidal cockroach spray that offers both fast-acting and long-lasting cockroach control. The most powerful cockroach killer available to the amateur market, as well as achieving a rapid knockdown it also leaves a protective residue that continues to kill cockroaches for up to 12 weeks after application. 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). As market leaders, our latest innovative formulation incorporates two additional active ingredients. The first is pyriproxyfen, a ground-breaking insect growth regulator that cleverly works by halting the progression of the lifecycle development from juvenile to adult, resulting in an inability for the cockroach to reproduce, and therefore ensuring there is no increase in numbers. The second is the addition of chrysanthemum cinerariaefolium extract, a natural pyrethrum, which when combined with the existing concentration of cypermethrin has a synergistic effect, helping to deliver an even faster knockdown and longer-lasting residual for ongoing control of all lifecycle stages. A 5-litre container provides enough insecticide to treat an area of approx 250m2.
