Mole activity increases in the springtime when the ground begins to thaw and insects become active. Spring is also the time when female moles complete their gestation period, so you may soon have more on your hands!
Typically in May a female mole gives birth to 2 to 6 naked babies in a cozy nest in one of the deeper burrows. Baby moles grow quickly. The babies can take care of themselves when they are only about one month old! At four to five weeks, the pups are weaned. By five to six weeks, pups leave their mother and their home tunnel completely. They are now independent and making their own burrows by late summer or fall.
Moles are solitary creatures that only come together to reproduce. Territories may overlap, but moles avoid each other. Males will fight fiercely if they meet. Eastern Moles do not live in families, so your yard is likely being pillaged by only one solitary critter. The range of a solitary mole can be as large as 2.7 acres! The underground network of a mole is made up of large, complicated burrow structures with distinct living and hunting areas.
