If you like to have a well-kept lawn in pristine condition, there is nothing worse than waking up to loads of little holes that were not there when you went to bed.

There are loads of potential candidates for who has been ruining your morning and making your lawn an eyesore so we are going to see if we can help you discover the who that culprit may be.

By looking at the size and the shape of the holes, we should have a good idea of who or what is creating small holes in your lawn overnight; some of them are obvious but a there are a few little blighters that can ruin your lawn that you may not have been aware of.

Another factor to consider is the time of the year as different seasons will mean that different animals are active, some of them may be laying eggs while others may be looking for something to eat.

What is Digging Small Holes in My Lawn at Night?

There are a variety of animals and insects that can create holes in your lawn and some of them do so for different reasons. In the UK, chances are that the holes that have appeared overnight are caused by moles, foxes, badgers, or squirrels but there are other animals and insects that could be the problem.

Once you have an idea of what size and shape hole is caused by what animal and what time of year they are active, you will then know what to do next. If you want to try and prevent it happening in the future (that is if there is anything that can be done), you will want to consider one, if not all the below.

Time of Year

The time of year is an important factor to consider when you have holes appear in your lawn overnight. For example, foxes may dig holes in your garden in the autumn or early spring looking for grubs and earthworms. Grubs and earthworms are closer to the surface in wetter conditions meaning that they are easier to find when the ground is softer.

Shape

The shape of the hole is often a major clue in determining what is causing the holes in your lawn. Some pests and insects leave conical mounds and others will leave a mess. For example, an earth worm will leave a small 2cm mound of soil around a hole whereas a mole will leave a huge mound the shape of a mini volcano.

Size

The size of the hole will certainly rule out some of the possible culprits as a hole 1 foot across is not likely to have been left by a bird that is plucking up earthworms. For example, a large hole like that could be an indication of badgers beginning to excavate a new sett whereas tiny holes may be caused by insects that are emerging into the world after hatching from their eggs.

Potential Culprits that May Dig Holes in Lawns UK

There are various potential culprits for small holes appearing in lawn overnight and to be honest if it something small like an earthworm or hatching insect, you may not even notice and the birds that may damage your lawn are only active during the day so we are going to look at some of the mammals that may be responsible.

Moles

Moles are subterranean mammals that spend most of their life in solitude underground except for during the mating season where they will encounter others.

Moles are good for tilling soil and eating bugs and larvae that may become pests in the future, but they can be a real nuisance if they get under your lawn.

Molehills are easily recognised and take shape as small volcano looking mound about 1 ½ feet across with a small 2 to 3-inch hole at the top. Molehills are created when a mole is constructing new tunnels or repairing damaged ones and needs somewhere to get rid of the waste soil.

Moles are notoriously difficult to get rid of humanely but there are a few good ideas that you can try.

Foxes

Foxes are scavengers and can often be found wandering around gardens looking for their next meal whether that be in the rubbish or if the weather permits, your lawn.

As we mentioned earlier, foxes may be a problem when the ground is soft and wet when earthworms and grubs tend to be closer to the surface. A single fox could easily make mincemeat of your lawn in just 1 night in search of tasty morsels that may be just out of sight.

Fox holes look like what a dog may dig as the holes are dug in much the same way. Foxes will use their paws to continuously scrape back the soil until they find what they are looking for.

Squirrels

As you may know, squirrels are little rodents and they grey squirrel here in the UK is considered vermin.

Squirrels can be a particular nuisance to lawns when they are burying their nuts and then digging them up again and squirrel holes are typically a little smaller than holes dug by foxes and are only usually 1 to 2 inches deep and they are usually back filled with some loose soil.

Furthermore, squirrels are not active at night so if you suspect squirrels and you are an early riser, you are likely to catch them in the act at dawn. Read more on squirrels digging holes in your garden.

Badgers

Badgers are certainly creatures of the night and many people go through life not even seeing one in the wild except when they drive past one laying at the side of the road after an unfortunate accident.

Badgers can be a real pain for gardeners as they will not only eat earthworms and grubs, but they will also dig down and eat your bulbs. They are particularly fond of tulips so if holes are appearing in your lawn around the time of your tulips going missing, badgers are likely to be the cause!

Birds

Magpies are also well known for digging in lawns but this is usually during the daytime and not at night. Magpies will be searching the lawn for grubs and other tasty insects like leatherjackets.

Conclusion

Holes appearing in your lawn at night can be a real pain and holes in large numbers can be devastating. Holes from earthworms and small insects will not really cause you a problem, it is mammals that are often the real menace and can make even the most pristine of lawns look like a cow-field overnight.
