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.

Aggregate customer ratings are mixed rather than uniformly positive. 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.
