Formula C is a fast-acting flea spray with a rapid knockdown effect. As well as killing fleas on contact, Formula C offers long-lasting residual protection, helping maintain flea control for up to 4 weeks. The spray can be applied to carpets and other surfaces in the home for the effective control of cat fleas or dog fleas.
Until recently Pest Expert Formula C has only been available for professional use. As it has now become available to the amateur market, we have chosen to replace the previously sold Protector C / Insectaclear C with this fantastic product.
Formula C is a professional strength insecticide containing cypermethrin at 0.1%w/w and is designed as a surface spray for the control of many insect pests including fleas, cockroaches, moths, ants, and flies.
Formula C is water-based, so providing packaging instructions are followed, it is perfectly safe for use in homes with both children and pets and will not cause damage to any items that would not be damaged by water.
A 1 litre trigger spray will treat an area of approximately 20 square metres.
Formula 'C' Flea Killer Spray is supplied with a Free EN149 Safety Mask and Nitrile Safety Gloves, strongly recommended when applying any flea killer sprays or quality insecticides!
