Moles and voles are rodents. They can do a lot of damage in a short amount of time to lawns, trees, plants and shrubs. They can come from wooded areas, fields and even your neighbors' yard. 

Moles and voles remain active even during the winter, so you may not notice the mounds and tunnels until the snow melts. Once you notice activity, it's important that you act quickly! A maintenance program works best, as they reproduce rapidly.
