I'd like to see greater use made of the CO2, resetting kill stations that have come on the market. They use poison free baits and can kill 10-15 times before the mini gas canister needs to be replaced. We've just bought one for stoats/rats, as we haven't had any luck catching stoats with anything else.
The possum version can screwed onto the trunk of a tree, out of the way of other animals. The replacement baits and gas canisters don't cost much either. Which is more than I can say about the replacement margarine-container-type poison block that fits in a bait station attached to a tree. Those things are a ridiculous price now. I don't see why the price has gone up? It'll be too expensive to use in any great quantity.
If the gas powered captive bolt killing stations had larger gas cylinders, they'd be useful in bush situations.
