Moles are a common British mammal living almost exclusively underground, although they are capable of moving above ground and even swimming. As well as a means of transportation, the main purpose of the tunnel network is a trap for worms and other invertebrates to fall into. The mole rarely exceeds 20cm in length (including short tail) and has a very smooth dark fur which can flex in both directions. With very poor eye-sight, the mole navigates and finds food largely by picking up vibrations.
Moles are typically solitary, and both sexes defend their territories vigorously, often coming together just to mate. Moles will often have just one litter per year, consisting of up to 7 young. The young are suckled for about a month and leave the nest after about 5 weeks.
Where professionally trained, the gassing compound, Aluminium Phosphide can be used. Much mole work is done using a variety of traps from barrel and scissor traps to the new and highly effective talpex style.
