Moles are solitary animals, around 6 inches in length, that live underground throughout Britain. They can tolerate lower oxygen and higher carbon dioxide levels than other mammals which enables them to spend most of their life sub surface. They will defend their territories aggressively from other moles.
They only come together during their mating season (February/March). Up to five young moles can be born at a time, and these will generally leave the nest to find their own territories after 30-45 days.
Mole Hills and Tunnels
Mole hills are the result of all the burrowing from the moles when they are creating their underground tunnels. Some of the earth is patted down along the base of the tunnel and the rest is pushed above the ground to create the mole hills.
A mole hill is usually the first indication that you have a mole problem. However, beneath the surface is where the real activity occurs. Moles can dig at a ferocious rate of up to 12-15 feet per hour and create an underground tunnel network of up to 200 metres in the search for food.
The mole's diet is primarily the earthworm. The tunnels that a mole digs are used to trap the worms that fall into them from above. The worms are quickly devoured by the mole, whose time is split between feeding and sleeping cyles at various intervals throughout the day and night.
Moles are hungry creatures that can eat close to their body weight in worms (around 20) per day.
