## Before you buy

- 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.

## 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.

## Customer feedback

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.

## Frequently asked questions

### How are these granules intended to be used?
