Pest Expert Formula 'C+' Cluster Fly Spray contains cypermethrin (0.1% w/w), which kills cluster flies fast and leaves a long-lasting residue that maintains cluster fly control for up to 12 weeks.
Formula 'C+' is a ready-to-use insecticide that is safe for direct application to alighting surfaces including window frames and roof timbers. As Formula 'C+' is water-based and low odour, it is ideal for treating cluster fly infestations in domestic homes as well as in commercial premises.
Five litres provides effective coverage to an area of approx 100 sq m. The product should ideally be administered using a pressure sprayer to enable a thorough and even distribution of insecticide.
For a comprehensive cluster fly treatment, we recommend using alongside Pest Expert Formula 'P' Cluster Fly Powder and Pest Expert Formula ‘P+’ Foggers as the combination of different active ingredients enables a faster and more effective knockdown.
