What Is Burrowing Under My Lawn? Identifying Summer Garden Pests

Discovering holes, tunnels or mounds of soil across your lawn can be frustrating, particularly during summer when you want to enjoy your garden. Several animals and insects may be responsible, so correctly identifying the signs is important before considering garden pest control in Devon.

Moles

Moles are one of the most recognisable causes of lawn damage. They create raised ridges and distinctive molehills while tunnelling underground in search of earthworms. Although moles rarely appear above ground, their tunnels can disturb roots and leave lawns uneven. Fresh molehills appearing overnight usually indicate active tunnelling.

Rats

Rats may burrow beneath sheds, decking, compost bins and dense vegetation. Their entrance holes are generally smooth and often surrounded by compacted soil. You may also notice droppings, gnaw marks or well-worn routes through the grass. Accessible bird food, household waste and pet food can attract rats to Devon gardens.

Wasps

If insects are repeatedly flying in and out of a hole in the lawn, you may have a ground wasp nest. Activity often becomes more noticeable during late summer as the colony grows. Avoid covering the entrance or disturbing the nest, as this could cause the wasps to become defensive. Contact a professional if the nest is close to children, pets or frequently used areas.

Ants

Ants create much smaller openings, sometimes surrounded by fine, loose soil. Several small mounds across paving edges or dry sections of lawn can indicate an established colony. While garden ants are usually harmless, they can become a nuisance when nests spread into patios or nearby properties.

Other Wildlife

Foxes may dig shallow holes while searching for insects or buried food. Badgers can produce larger areas of disturbed turf when looking for grubs and worms. Because badgers and their setts are legally protected, seek specialist advice before taking any action.

The size and shape of the hole, nearby droppings, tracks and the time activity occurs can all help identify the cause. Avoid placing poison or traps without knowing which animal is present.

If unexplained burrows continue appearing, a professional pest inspection carried out by Devon Pest Control can identify the culprit and recommend a safe, responsible solution for protecting your lawn and property.
