A pest is any animal which has the capacity to do one or more of the following; cause Damage, spread Disease or trigger Distress. Therefore it is important to note that a pest isn’t just a specific species such as ‘rats’.
A rat in the forest for example isn’t a pest, it is a fundamental part of the ecosystem. However that same rat in a cattle shed becomes a pest when it damages food stores, distresses the livestock and brings the potential for disease transmission.
