The black boxes positioned around our towns – outside of restaurants and supermarkets, next to dumpsters, maybe even in your neighbor’s yard – certainly serve a purpose. People understandably don’t like rats, so they aim to mitigate this problem by baiting the boxes with a poison known as SGARs (Second Generation Anticoagulant Rodenticide). The anticoagulants interfere with the affected animal’s ability to produce Vitamin K, leading to fatal hemorrhaging due to its blood’s inability to clot.
