Product information
Formula 'C' is the most powerful insecticidal flea spray available to the amateur market. As well as being a fast-acting flea treatment, Formula 'C' also offers long-lasting flea control as the protective residue it leaves behind continues to kill for up to 12 weeks after application.

Formula 'C' is effective against both dog and cat fleas and, being a water-based insecticide, it is safe for direct application to rugs and carpets.

Formula 'C' is virtually odourless and contains no solvents, so it is perfectly suitable for use in households where there are children and/or pets, as long as they are kept out of the area being treated until all surfaces are dry (approx 2-3 hours).

The active ingredient in Formula 'C' is the powerful broad spectrum insecticide cypermethrin (0.1% w/w), which is also effective against a wide range of flying and crawling insects.

A one litre trigger spray contains enough insecticide to treat an area of approx 20m2.
One application should be sufficient for a successful treatment, although a second application may be necessary if the flea infestation is particularly heavy or flea eggs are deeply entrenched.

Directions for use
Apply Formula 'C' spray to affected areas, floors and carpets, paying particular attention to the edges of the room, where fleas often lay their eggs.  

Avoid cleaning or vacuuming the treated areas for as long as possible as this will remove the protective residue.

Do not apply directly to pets or pet bedding.

For a more comprehensive treatment, fumigation devices such as Pest Expert Formula 'P' Flea Bombs should also be used.  For safe treatment of pet bedding, please see our organic Agrothrin Powder.

For the best value for money please see our
Flea Kits, which contain a combination of our best flea killer products, including Formula 'C', Formula 'P' Flea Bombs and Agrothrin Flea Powder.

Treatment of the home should always be carried out alongside treatment of your pet(s), especially if this is the source of the initial infestation. Always see a qualified veterinarian for advice on the best flea products for your pet.
