Product information
Pest Expert Formula 'C' is a highly-effective insecticidal cockroach spray that offers both fast-acting and long-lasting cockroach control. The most powerful spray available to the amateur market, as well as achieving a rapid knockdown it also leaves a protective residue that continues to kill cockroaches for up to 12 weeks after application!

Formula 'C' is low-odour and free from solvents, so it 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).

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.

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.
