How Many Eyes Do Moles Have?

Do Moles Have Eyes?

Yes. Moles have two eyes, the same as almost every other mammal. But they are so small and so well-hidden that plenty of people assume moles are eyeless — and one of the more common questions we get in our Western Washington mole trapping calls is whether moles even have eyes at all.

The confusion is fair. On a Townsend's mole — the largest species in North America and the one you almost certainly have if you're finding mounds in a Seattle, Bellevue, or Tacoma yard — the eyes are roughly the size of the head of a pin. They're set deep in the fur, often hard to spot even when you're holding the animal. On shrew moles, which are smaller still, the eyes are barely visible at all.

The eyes are there. They're just not doing much of the work.

Can Moles See?

Moles can detect light. That's about it.

After millions of years of evolution underground, their eyes have simplified down to the bare minimum needed to tell light from dark. Some species have a thin layer of translucent skin growing over the eyes altogether. The retina still fires when light hits it, but the lens doesn't focus sharp images the way yours does, and the brain isn't wired to process detail even if it did.

So moles aren't blind in a strict biological sense — they have functioning eyes and a working optic nerve. But they don't see shapes, they don't track movement visually, and they don't navigate by sight. For a related breakdown of what moles perceive and how it compares to human vision, see Are Moles Blind?.

Why Do Moles Have Eyes If They Can Barely See?

For a mole, the single most important thing its eyes do is warn it when something is wrong.

If a mole hits daylight, it has exposed itself — usually by accident, sometimes because a tunnel collapsed — and it's now extremely vulnerable. Coyotes, hawks, owls, domestic dogs, and even heron have all been documented taking surfaced moles. A split-second light-detection response tells the mole to reverse course fast and get back into the dirt.

That's the reason the evolutionary pressure to keep eyes at all hasn't disappeared. Light-sensing saves mole lives. Seeing color, depth, or detail would not.

How Do Moles Navigate if They Can't See Well?

Touch and smell carry the load.

A mole's snout is covered in extremely sensitive whiskers called vibrissae and — more importantly — specialized sensors called Eimer's organs. These microscopic domes, packed in the hundreds across the tip of the snout, detect the faintest air currents, soil pressure changes, and the vibrations earthworms produce as they move. Earthworms make up 55 to 93 percent of a mole's diet in Western Washington — the rest being grubs, centipedes, slug larvae, and the occasional insect — so tuning those sensors to worm-frequency was a survival requirement.

Their strong forelimbs are built for digging. Large, shovel-shaped paws let a mole tunnel through wet PNW clay soil at up to 18 feet per hour when the soil cooperates. Once a tunnel network is in place, the mole patrols it repeatedly, memorizing the route through touch. When a new worm falls through the soil into the tunnel, the mole often reaches it within minutes.

One species — the star-nosed mole — takes this further than any other mammal on earth. Its nose is ringed with 22 pink fleshy appendages covered in over 25,000 touch receptors. It can identify and eat prey faster than the human eye can follow. Star-nosed moles don't live in Washington, but they're proof of how far the mole family has leaned into touch over vision.

Do Washington's Three Mole Species Differ in Eye Size?

Slightly. All three species found in Washington State — Townsend's, Pacific Coast, and Shrew mole — follow the same basic pattern: tiny, deep-set, light-only eyes.

Townsend's mole is the largest species in North America at 8-9 inches long and 4-5 ounces. Its eyes are pinhead-sized and buried in velvety black fur. You have to part the fur to find them.

Pacific Coast moles are about two-thirds the size — 6-7 inches, 2-3 ounces — and have proportionally similar eyes. Identical function. Some individuals have a thin membrane of skin that grows over the eye entirely, which doesn't seem to affect their behavior because they weren't using vision to begin with.

Shrew moles are the smallest, under 4 inches total. Their eyes are so tiny that casual observers routinely miss them entirely. Unusual among moles, shrew moles forage above ground more often — in Western Washington, typically in wet leaf litter along wooded property edges. You'd think that would favor better eyesight, but their eyes remain the simplified mole version.

Why Is Mole Control Important?

Moles are fascinating creatures, but they are also hard on a lawn. A single Townsend's mole in an active feeding cycle can throw up fresh mounds every day, collapse surface tunnels under foot traffic, and undercut irrigation lines and sprinkler heads. In the wet PNW soils between March and June — peak mole activity season — a small population can turn a $15,000 lawn into a minefield inside a few weeks.

The fix is rarely about repelling a mole. It's about removing it. Repellents, sonic stakes, castor oil, and grub killers don't work reliably on Townsend's moles — we've excavated enough treated yards across Seattle, Tacoma, and Enumclaw to be confident on that point. Chemical-free professional trapping is what gets results and what our Total Mole Control Program and One-Time Mole Removal services are built around.
