Pest Expert Formula ‘C+’ Advanced Cluster Fly Spray is the most powerful residual insecticide available to the amateur market and is an upgraded version of our previous best seller, Formula ‘C’. Formula ‘C+’ Advanced contains three ground-breaking insecticides that work simultaneously to provide long lasting cluster fly control. The new to the market formulation contains Pyriproxyfen, an innovative insect growth regulator that works by halting the life cycle, ensuring the incapability of numbers rising. Chrysanthemum Cinerariaefolium Extract has been added which is a 100% natural Pyrethrum, and when incorporated with the existing Cypermethrin, delivers rapid knockdown and long-lasting control of the whole life cycle for up to 12 weeks.

Cluster flies will die on contact with the invisible insecticidal residue and the Pyriproxyfen will get to work by stalling the whole life cycle, resulting in the inability of the flies to reproduce, leading to a reduce in numbers. As Formula ‘C+’ Advanced is water-based, solvent-free and low-odour it is perfectly suitable for use in homes with children and/or pets, and can be applied to any alighting surfaces, window frames and roof timbers, as it is non-staining it will not damage any application surfaces. One 5 litre container will treat an area of approximately 250 square metres.
