Pest Expert Formula C+ Advanced Flea Killer Spray is the new and improved formulation of our bestselling original product, Formula C. Formula C+ Advanced is a ready-to-use triple action flea killer, with a long-lasting residual that maintains flea control for up to 12 weeks. Its unique combination of actives make it the most powerful flea spray available to the amateur market, and the ultimate insecticide for anyone wanting fast and effective eradication of any size flea infestation.
• Fast-acting: Rapid knockdown Product information
• Low-odour: No smell during or after use
• Non-staining: Will not damage carpets or rugs
• Long-lasting: Residual maintains flea control for up to 12 weeks
• Increased coverage: 1L now treats up to 50m2 in a single application
As market leaders, our latest innovative formulation now incorporates two additional active ingredients. The first is pyriproxyfen, a ground-breaking insect growth regulator that cleverly works by halting the progression of the flea’s lifecycle development from juvenile to adult, resulting in an inability for the flea 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.
With approval for both professional and amateur use, this professional-grade product can also be used safely in the home. Formula C+ Advanced is easy to use and can be applied directly to carpets and rugs as it is water-based and non-staining, so will not cause any damage.
Being low odour and free from solvents, Formula C+ Advanced 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).
Formula C+ Advanced now offers an increased coverage of up to 50 sq m per litre,
One application should be enough for a successful flea treatment. However, to eradicate a particularly heavy flea infestation then a second application may be required.
As a broad spectrum insecticide, Formula C+ Advanced is also highly effective against a wide range of flying and crawling insects including bed bugs, cockroaches and moths.
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.
