A line of pushed up grass. A volcano sized mound. Yep, it's probably a mole! While you may never actually see the mole itself, the signs of their presence are pretty clear.
Moles are small burrowing mammals (not rodents) that live almost entirely underground in extensive tunnel networks. Since they prefer worms, they don't typically eat plants, but their burrowing can damage plant roots and leave unsightly ridges in lawns. You'll usually only find one mole per tunnel so if you start your control actions as soon as you spot their burrowing, you can more easily manage them.
Fortunately, UC IPM has a newly updated resource to help in your mole management efforts! This revised fact sheet,

In this blog article we answer some frequently asked questions about moles, voles, and gophers and their management.
How can I tell if I have moles, voles, gophers, or something else?
Moles: look for circular or volcano-shaped mounds with the plug in the middle, or a plug may not be apparent. The soil of mole mounds tends to be clumpier than gophers. Moles sometimes leave a raised ridge just beneath the soil surface while hunting for food.
Voles: look for aboveground runways that connect burrow openings. Grass usually covers the burrows. Voles can girdle trees...

Gophers are well-known and certainly unwelcome pests in landscapes, gardens, lawns, and athletic turf. More correctly called pocket gophers, these rodents mostly remain hidden underground in tunnels and feed on plants from below, sometimes pulling whole plants into their tunnels. They prefer herbaceous plants but will eat a wide range of vegetation.
A single gopher can destroy a landscape quickly, so control measures need to begin as soon as the gopher is detected. Mounds of fresh soil are usually the first indication of their presence. Effective integrated management of pocket gophers relies largely on exclusion measures and trapping, although poison baits are also available.

Finding freshly dug mounds of soil in the garden, lawn, or landscape might be a sign of gophers or moles. Their mounds look similar and are frequently confused for each other.
Figure 1 shows a mole mound, which usually is volano-shaped with a circular margin. Figure 2 illustrates a gopher mound and the characteristic crescent shape and plugged opening. Actual mounds may look slightly different from these pictures, but the descriptions are typical of the two vertebrates.
The burrowing activity of both moles and gophers can damage plant roots by dislodging and drying them out. Mounds themselves can be an aesthetic problem in turf and landscapes, but they can also be tripping hazards. Both species eat plant material, and in...
