Fresh ridges snaking across a New Jersey lawn almost always mean a mole is at work underneath, and homeowners understandably want to know exactly what they're dealing with. New Jersey is home to two species — the star-nosed mole and the eastern mole — and while both leave a lawn looking similarly chewed up, the animals themselves are built for very different ground. Only one of the two is common in an average yard; the other prefers conditions most residential lawns simply don't offer.
The Star-Nosed Mole: Impossible To Mistake For Anything Else
Spot one of these animals out in the open, and there's no question what you're looking at. A star-nosed mole carries a ring of 22 fleshy, pink, finger-like tentacles around its nose, an extremely sensitive touch organ it depends on constantly. That's because this mole is nearly blind and hunts almost entirely by feel, reading prey moving through mud and water in a fraction of a second. It also does something most moles never do: swim, and swim well. Consistently wet, poorly-drained soil near streams, marshes, or the one low corner of a yard that never quite dries out is exactly where it wants to be, and earthworms plus aquatic invertebrates make up most of what it eats. Because it works shallow ground in saturated turf, its tunnels show up as raised ridges right where the grass stays soggiest. If your property backs up to a stream or holds water in one persistent low spot, our wildlife removal specialists can confirm whether that's actually the animal behind the activity before you assume the worst.
The Eastern Mole: NJ's Actual Lawn Culprit
Most of the calls we get, though, trace back to the eastern mole. It skips the dramatic nose entirely — just a plain, pointed snout — and wears velvety gray-black fur that almost looks brushed. Its front paws are the real giveaway: large, paddle-shaped, and built purely for pushing through soil fast. Unlike its wetland cousin, this species prefers well-drained, drier soil, which happens to describe most residential lawns across Essex, Morris, and Bergen counties. Earthworms and grubs make up the bulk of its diet, and its digging shows up two ways: the same raised, winding ridges near the surface, plus larger volcano-shaped mounds where soil has been pushed up from deeper tunnels below. EcoFusion Pest Control has walked hundreds of these yards over the years, and that firsthand, local experience is exactly why homeowners across the area lean on us to tell a passing tunnel from an active infestation. If grub activity is feeding the problem, a home pest-proofing visit can flag the conditions drawing both the digger and its food source onto the property.
Star-Nosed Mole vs Eastern Mole: Side-By-Side
Once the two are lined up feature by feature, the differences are easy to spot.
| Feature | Star-Nosed Mole | Eastern Mole |
|---|---|---|
| Nose / Snout | Ring of 22 pink, finger-like tentacles | Plain, pointed snout — no tentacles |
| Fur | Dark, dense, water-resistant coat | Velvety gray-black |
| Preferred Soil Moisture | Wet, poorly-drained soil near streams, marshes, low spots | Well-drained, drier soil typical of most lawns |
| Swimming Ability | Excellent swimmer — hunts underwater | Doesn't swim; strictly a digger |
| Diet | Mostly earthworms and aquatic invertebrates | Mostly earthworms and grubs |
| Typical Lawn Damage | Shallow surface tunnels showing as raised ridges in wet turf | Raised, winding ridges plus volcano-shaped mounds from deeper tunnels |
Telling Them Apart Without Seeing Either One
Most homeowners never actually spot the animal responsible, so the nose isn't always a useful clue in practice. Soil moisture is the tell that actually works day to day. A star-nosed mole sticks to ground that stays wet and marshy, so if the tunneling is happening in a normal, well-drained section of lawn, an eastern mole is almost certainly the one responsible instead. That's precisely why it shows up in the overwhelming majority of NJ yard-tunneling complaints — it's simply built for the soil conditions most yards actually have. Pair that moisture check with a glance at nearby shade and drainage, and the guesswork mostly disappears: a yard bordering wetlands or holding standing water after rain leans toward the wetter species, while everything else typically comes back to the common lawn digger. If rodents have also been active near that same soggy corner of the property, our Rodent Control in Wanaque team can take a look while assessing the tunneling.
Fixing The Damage, Whichever Mole Is Behind It
The good news is the fix barely changes depending on which species turns up. Both feed heavily on earthworms and grubs, so the visible damage — raised ridges, the occasional mound — looks nearly identical no matter which one is digging. Cutting off the grub supply removes the food source pulling activity toward that stretch of yard in the first place, and targeted trapping handles whatever tunnels are still active once the food's gone. Combine the two and most lawns settle down within a season. Because a soggy, mole-friendly yard tends to draw other unwelcome traffic too, our pest exclusion services can seal up the gaps rodents and other wildlife use to slip in from that same damp corner. Homeowners further along the Hudson dealing with a similar mix of yard pests can count on our Rodent Control in West New York crew for that same grub-and-trap approach.
