Moles in the lawn: what works without traps

Why moles dig in your lawn

Moles (Talpa europaea) do not eat grass or plant roots. They hunt insects: leatherjackets, wireworms and earthworms living in the top layer of soil. The richer your soil, the more attractive it is to a mole. The tunnels you see are hunting routes, not random holes: a mole follows the vibrations of moving prey and can dig up to 20 meters a day. A single mole defends a territory of roughly 2,000 to 7,000 square meters and often moves on after a few weeks in search of fresh hunting ground.

Here is the good news: moles naturally move on. You do not need to kill one to get rid of it. Driving it away and preventing a new one from moving in works just as well, and in the Netherlands it is also the only legal option, as you will read further down.

Mole netting under a new lawn: the best prevention

Planning a new lawn? Fine-mesh mole netting is the only method that works permanently. Buy plastic netting with holes of about 13 to 19 millimeters and lay it 25 to 40 centimeters deep, before you sow seed or lay turf. The mole hits the netting and cannot pass through, so it looks for hunting ground elsewhere. Expect to pay 10 to 20 euros per square meter depending on quality; it lasts for years and saves you from traps or repellents later.

Important: cover the full area, including paths and borders next to the lawn. A half-meter gap is enough for a mole to get in anyway.

Why sound devices do not work

Ultrasonic or vibrating mole repellers that you push into the ground promise a lot but deliver little. Moles get used to a fixed, predictable sound or vibration within one to two weeks and simply dig past it. Independent trials of these devices show no lasting effect. Spend your money on mole netting or better drainage instead.

A dense lawn is less attractive

Moles find it easiest to dig in loose, bare soil. A dense, well-kept lawn with perennial ryegrass and red fescue leaves less room for insects and is harder to tunnel through. Mow regularly at 4 to 5 centimeters, feed it twice a year, in spring and in September, and scarify it once a year, in April or September, to remove dead thatch.

Molehills: free potting soil from your own garden

Instead of sweeping molehills away, put them to use. The finely sifted soil in a molehill is often better than bought potting compost: light, nutrient-rich and free of surface weed seed. Collect molehills in autumn or early spring, sieve them once more through a 5-millimeter mesh and use the result for pot plants or to fill seed trays.

Improve drainage to fix wet soil

Damp soil attracts insects, and insects attract moles. If your lawn stays waterlogged after rain, improve the drainage: lay drainage pipes 40 to 60 centimeters deep, or loosen the soil by scarifying every year and working in sand or compost. Within one or two growing seasons you will see less mole activity, simply because there is less prey underground.

Attract natural predators

Hedgehogs, buzzards and certain birds of prey occasionally eat a mole or its young, and ground beetles compete with moles for the same insects. A border with leaf piles, a low gap in the fence for hedgehogs and a brush pile in a quiet corner make your garden more attractive to these allies. Avoid slug and insect poison: it reduces the food supply for the mole as well as its predators, which works against you.

Traps and poison: what is not allowed

Traditional mole traps and mole poison look like a quick fix, but in the Netherlands the mole has been a legally protected species since 2017 under the Wet natuurbescherming: catching or killing one without a permit is a criminal offence. In Flanders there is no approved poison registered against moles, so using one is not allowed either. Stick to the methods in this article instead: netting, drainage and a less attractive lawn, rather than traps or poison.

Step by step

Step 1: Map the tunnels

Walk your lawn early in the morning and look for fresh molehills: soft, dark soil without grass on top. Mark the route with a stick or a little paint. A mole usually keeps two to three active tunnels, so you only need to treat the active zones, not the whole lawn.

Step 2: Seal off the boundary

Dig a trench 40 centimeters deep along the border with a neighboring garden or shared green space and place mole netting in it vertically. This stops a mole from entering again and again from next door.

Step 3: Make your lawn less interesting

Stop extra watering for two weeks so the top layer of soil dries out. Less moisture means fewer insects there, and a mole naturally moves toward a damper part of the garden or the neighborhood.

Step 4: Place netting in active tunnels

Carefully open an active tunnel and lay a strip of mole netting across it, vertically in the soil. The mole hits it and digs around it, usually leaving the garden.

Step 5: Give it two to four weeks

Moles do not respond in a day. Check weekly for new hills. If they stop appearing, the mole has left; if they return, repeat steps 3 and 4 in the new spot.

Frequently asked questions

Am I hurting the mole by driving it away? No. Netting, drier soil or less food simply force the mole to hunt somewhere else. It is not injured and does not die from it.

Can I catch and relocate a mole myself? Not in the Netherlands without a permit, since the mole is a protected species there. In Flanders there is no approved poison or product for moles, so stick to the preventive methods in this article.

Can I still add mole netting under an existing lawn? Yes, but you need to lift the turf first, lay the netting and put the turf back. That is a lot of work, so it is easier to add it when you lay a new lawn.

How long before a mole leaves? Usually two to four weeks after installing netting or drying out the soil. Combine several methods for a faster result.
