The Residex P Woodlice Killer Powder 400g is the perfect solution for controlling woodlice in dry conditions and especially for those in difficult to reach areas such as cracks and crevices and voids.

The powder is sold in easy to apply puffers where it can be puffed directly into high activity areas for more targeted, accurate control. Once the woodlice ingest the powder it will slowly start to dehydrate them leading to eventual death in around 24 – 48 hours.

Once the powder is applied and left untouched it will create a deadly residue which can last up to 3 months for further control after the initial application

How to use

  • Once you have identified the target area simply puff the powder into any cracks and crevices and hard surfaces
  • Each powder comes in a puffer container for ease of use
  • If applied successfully the woodlice should be dead in around 24 – 48 hours
  • Simply hoover up the dead woodlice after use
