## Before you buy

- The manufacturer claims indoor and outdoor use only when used according to the label. Customer feedback reports mixed spray-distance experiences, including difficulty reaching nests beneath roof tiles, so it may be less suited to inaccessible nest locations.

## A good fit for

- People treating visible wasps or exposed nests in accessible areas.
- Buyers looking for an aerosol marketed for indoor and outdoor use subject to label instructions.

## Less suited to

- People who need a confirmed long-range spray to reach nests beneath roof tiles or other inaccessible spots.

## Customer feedback

Customer feedback highlights perceived effectiveness and ease of use, with some reporting that wasps were eliminated after repeated applications. Views on value are mixed, and spray distance is also a concern for some, including difficulty reaching under roof tiles. That limitation is relevant because the listing gives no range figure and describes treatment of exposed nests. Aggregate ratings are generally favourable but do not establish how well the spray reaches a particular nest location.
- Positive themes: Customers describe the product as effective and easy to use.
- Mixed feedback: Feedback is divided on value for money.
- Mixed feedback: Feedback on spray distance is mixed, with some customers describing it as short and unsuitable for nests beneath roof tiles.
