The Digrain C40 Cockroach Killer Powder is a wettable powder sold in 20 x 2g sachets for effective use against cockroaches congregating in difficult to reach areas.

Each sachet can be diluted in water and used in combination with an applicator for repeat use against large scale cockroach infestations.

This wettable powder can be sprayed directly onto cockroaches or onto hard furnishings where activity is known to be high. When applied the powder hardens leaving behind a deadly residue for further control.

This product is for professional use only and PPE equipment should be worn where necessary.

Contains Cypermethrin.

How to use

  • For effective results we recommend using this powder with a suitable applicator
  • Take two sachets and add to 1 litre of water
  • Add the mixture to the sprayer and shake it thoroughly to mix the contents.
  • If application is delayed for more than 30 mins try re-shaking the sprayer
  • Spray areas where there is high cockroach activity.
  • Do not use spray near electrical appliances, light fittings or switches.
