Usually found in wooded areas, chipmunks, or ground squirrels, have adapted to urban living very well. Look for tunnels near retaining walls, foundations, between tree roots and in dense plantings.
Love ‘em
Chipmunks are entertaining to watch and they do eat slugs and insects.
What to do
They can make a feast from almost any kind of seed you put out for them.

Hate ‘em
When they tunnel around plants, the roots dry out. Digging and tunneling can cause retaining walls to collapse. Chipmunks dig up and eat newly planted seeds and bulbs, as well as tender young plants and fruits.
What to do
Trapping may be your best option. Protect newly planted areas with hardware cloth placed over the soil to prevent digging. Spraying Wilt-Pruf® on the edges of containers sometimes keeps chipmunks from climbing in and digging.
