What is sherman trap?

The Sherman trap is a type of small mammal trap that is commonly used in scientific research for capturing and studying small animals such as mice and voles. It is named after its inventor, Dr. Sherman, who created it in the 1950s. The trap is made of metal and has a door that closes when the animal enters to collect the bait. The trap is usually set up in a location where there is a high concentration of small animals, and can be used in both indoor and outdoor environments. The captured animal is typically assessed for factors such as weight, gender and age before being released back into the wild. The Sherman trap is considered to be humane as it doesn't harm the animals during the capture process.
