The CO₂ canister is the all-important part which powers your trap.
Early on, Goodnature discovered that not all gas canisters are made equal. They tested dozens from different makers around the world before choosing the highest possible quality made of recyclable steel and a dab of silicone to keep your trap running smoothly.

To maximize the life of your trap, we highly recommend you use Goodnature-branded canisters.
Each canister contains 16g of CO₂. It powers your A24 trap for rats and stoats for 24 kills or A12 possum trap for 12 kills.
