| Biz was very impressed with the diphacinone bait. Bait acceptance was excellent and lasted well. | Bait take was higher on the cliffs and slopes (coastal areas) where rat populations were concentrated. | |

| All offshore rocks and stacks were treated. Only some smaller and steeper offshore rocks did not have rats. | Norway rats first escaped to Canna from ferry traffic a century or more ago. Quarantine procedures prevent rats from escaping on the island today. | |

| Monkey melting chocolate for rat indicator baits. | Monitoring bait consisted of chocolate flavored wax blocks, made of melted candles and cocoa. They were placed between existing bait stations on a chew stick held together by wire. | These non-toxic attractors were designed for rats to give away their presence. |

| Chocolate/wax blocks helped the team identify pockets of rat activity by attracting any rats that were wary of entering a bait station. | Biz and company examine tooth marks left on bait and indicators to determine if rats still persist. | Monkey sits by bait stations which will be permantly placed at the pier. Inside each box are 2 traps, chocolate wax block and soap to attract any rat coming ashore from a berthed ship. |
