Adult rats can be difficult to trap. They're highly intelligent, and wary. This 'walk the plank' style trap overcomes that wariness, and can catch multiple rats each night. It's 99% built from our scrap pile.
Conventional spring traps are indiscriminate. If they're used outside they can kill and injure wild birds. This trap is safe for wildlife, even baited.
I first started building this during the first lockdown, and finished it during the third.
