The female rears a litter of 3-4 young, the main breeding season being from February to June. The young weigh only 3g when born, and are fully grown by 8-9 weeks. The young moles leave their parents' tunnel systems after a few months and either take over old systems or establish new ones of their own. Prevention and control The only effective way we know of to control moles, without using poisons, is to trap them. Mole trapping is a skilled job, best done by an expert.
Moles are clever creatures, however, and can learn to avoid traps.
Trapping is not a long term solution and will have to be repeated every year or so. There are plenty of other methods that have been suggested to control moles, all of which are said to have worked for someone. The weasel is the mole's natural enemy. If there is a weasel in the district it may well nip down and clear out the mole, either by killing it or driving it away. If the tunnel system is not too extensive, flooding it with water in the spring can help to eject the moles.
