About Moles

General Mole Facts

Moles are mammals that live almost entirely underground. They belong to the family Talpidae. They are classified in the ancient order Insectivora (literally “Insect-Eaters”). Using their cylindrically-shaped bodies and webbed, clawed feet, moles practically swim in the dirt under your lawn in search of food. This search results in tunnels and mounds of dirt in your lawn/grass.

Types of moles

There are 2 main types of moles here in the Pacific Northwest:

Townsend Mole
Total Length: 7 1/2" – 9 1/2"
The Townsend Mole is the largest of the seven species found in North America. It is regarded as the most damaging of the western mole species.

Coast Mole
Total Length: 5 1/4" – 6 3/4"
The Coast Mole is also known as the Pacific Mole. Its appearance is very similar to the Townsend Mole, except that it’s somewhat smaller in size. The Coast Mole is also quite destructive and individual moles have been known to construct several hundred mounds during the course of a single winter.


Moles are insectivores and their principle food source is the earthworm. Grubs, larvae, beetles, snails, slugs and other subterranean insects effectively constitute the remainder. Moles have a high metabolic rate and must consume large quantities of food in order to meet the extreme energy requirements which excavation demands. A 4 oz mole will eat approximately 40 lbs of food per year and must consume an amount equivalent to 60-100% of its body weight daily.

Excavating Power

In just 20 minutes, a mole can excavate 10 lbs of soil or an amount equivalent to nearly 50 times its own body weight! As a point of reference, a 200 pound man (a mole guy) would have to shovel approximately 10,000 pounds of earth!

Moles Don't Just Disappear

Moles don’t hibernate, but will tend to go deeper during times of colder weather. They are active year round. Moles will not go away, at least, not on their own and will continue to add on to their tunnel complexes. The system of burrows represents a tremendous investment of energy and are therefore closely guarded by means of scent marking. Once vacated, either through natural mortality or “Trapping”, the tunnel system is subject to reoccupation by another mole. This re-colonization can occur quickly.


The conclusion of University researchers, biologists and extension specialists worldwide is both simple and consistent: Trapping is the MOST effective and reliable method to a mole-free yard.
