Pest Expert Formula C+ Advanced Cockroach 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 cockroach killer, with a long-lasting residual that maintains cockroach control for up to 12 weeks. Its unique combination of actives make it the most powerful cockroach spray available to the amateur market, and the ultimate insecticide for anyone wanting fast and effective eradication of any size cockroach infestation.

• Fast-acting: Rapid knockdown
• Low-odour: No smell during or after use
• Non-staining: Will not damage carpets or rugs
• Long-lasting: Residual maintains cockroach control for up to 12 weeks
• Increased coverage: 1L now treats up to 50m2 in a single application

Product information
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 cockroach’s lifecycle development from juvenile to adult, resulting in an inability for the cockroach 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 the 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 cockroach treatment. However, to eradicate a particularly heavy cockroach 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 moths, bed bugs and fleas.

Directions for use
Administer spray to affected areas, paying particular attention to the edges of the room, around pipes and drains, and any other cracks and crevices which may be harbouring cockroaches. 

Also inspect inside kitchen units, under sinks, behind appliances and between tiles/floorboards etc and treat as necessary.

Do not apply spray to food preparation surfaces.

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

For a more comprehensive cockroach treatment, fumigation devices such as Pest Expert Formula 'P' Foggers or Smoke Bombs should be added along with Pest Expert Formula 'P' Powder for use where spray is not suitable (e.g. around power points, behind electrical appliances/equipment).

Cockroach traps are also recommended as they help trap and kill cockroaches and are also a good way of identifying the location of harbourages, establishing the size of the infestation and helping monitor activity following treatment.
