What to know before buying

Listing details to confirm

The listing gives conflicting pack measurements: the title and size field say 650g, while volume fields state 0.6 Kilograms and a separate unit-count field states 650.0 gram. It also describes a long-lasting, slow-release aroma but supplies no duration or coverage figure. Confirm the selected listing's pack details and do not treat the scent claims as a measured rodent-control result.

Who is it for?

A good fit for

  • Buyers seeking peppermint-scented granules to scatter in indoor or outdoor areas.
  • People maintaining areas such as sheds, garages, gardens, storage spaces or bins.

Less suited to

  • Buyers who need a specified coverage area or scent duration, as neither is provided.
  • Buyers looking for a trap or bait product rather than scatter-on granules.

That offers only a broad signal about reported satisfaction and does not establish whether the peppermint scent, longevity or rodent-control claims perform as described. There is no supplied written feedback explaining the ratings.
