About Moles

Quick Facts:

  • Moles are insectivores and eat worms, bugs and grubs.

  • Moles are not chewing up your lawn looking for the Chafer Beatle Larvae.

  • They tunnel underground and create mounds of dirt in your yard.

  • They are solitary and territorial.

  • Once a year, males search for females to mate.

  • After mating, the female raises her young until they are old enough to find their own territory.

  • Moles are active year-round and will follow worms wherever they go.

Mole behavior and activity can vary based on species, location, and climate. The information provided below is based on our experience and may not perfectly reflect your situation.


North America is home to 7 of the 30 different species of mole. The 4 of those seven that are known to live on the west coast are;

  1. Townsend's mole

  2. Coast mole

  3. American shrew-mole

  4. Broad-footed mole 

Moles are insectivores, not rodents, meaning they only eat what creeps crawls and wriggles. That means they don't ever have to come above ground. In order for a mole to survive, they have to eat half their body weight in worms every day. That's almost 100 worms a day! 


The mounds you see popping up in your yard are the excess soil from a mole making a feeding tunnel. The mole is strong enough to move through the dirt by pushing it to the side but then it's too dense for a worm to move through. The mole will go back through the tunnels and loosen up the soil sending the excess upon your perfectly manicured lawn.


Moles love to follow landscaping ties, paving stone, sidewalks and driveways. If you lift a paving stone you'll see why. It's like a creepy-crawly buffet!


You might think your yard is infested with moles but they are actually very territorial. One mole patrols its encampment which varies in size depending on how many worms you have in your yard.


Remember it has to eat half its body weight every day. The mole leaves a scent trail in its tunnels to keep neighbouring moles out. 

Our experience in the Fraser valley has taught us that Moles usually reproduce once a year. The males are now seeking a female and this is where you might see one mound pop up in December and then nothing. It's likely a male passing through looking for a female.


Once he finds a female he can't stick around too long. Get the job done and get out! He's in her territory and she will fight to protect it.


Usually, by May she will give birth to 2 - 4 young. By June they are old enough to eat worms and she can't have them taking from her supply. She will chase them out to find their own territory.


If they can't dig fast enough they may come up out of the ground to getaway. This is generally the only time you might see a mole above ground. 


Moles are active year-round. They have to eat to survive so they go where the worms are. Some worms burrow deep below the frost line so that's where the mole will go.
