What’s Digging Holes in My Arizona Yard? How to Identify the Likely Pest
You notice a fresh pile of dirt beside the lawn. Then another appears near the garden. A few days later, there’s an open hole under a shrub that you swear wasn’t there before.
Something is digging in your yard.
The difficult part is figuring out what.
Arizona has several rodents and other animals that burrow, and the size of the hole alone usually isn’t enough to identify the culprit. A better approach is to look at the entire area: where the hole is located, whether it’s open or plugged, the shape of the displaced soil, nearby plant damage and whether new activity keeps appearing.
Early Bird Pest Control provides rodent and gopher control in the Phoenix Valley for homeowners dealing with gophers, pack rats, roof rats, mice and other unwanted pests.
Start With the Dirt, Not Just the Hole
Before filling anything in, look at how the soil has been moved.
Is there a mound?
Is the dirt piled primarily on one side of the opening? Is there a fan-shaped area of loose soil? Is the actual entrance easy to see, or does it seem to have been plugged back up?
Those details are often more useful than measuring the diameter of the hole.
Take a photo before raking or disturbing the area. If more holes or mounds appear over the next several days, you’ll have something to compare them with.
Fan-Shaped Mounds Often Point Toward Pocket Gophers
If fresh soil is appearing across your lawn or landscaped area without an obvious open entrance, pocket gophers should be high on the list of possibilities.
The University of Arizona Cooperative Extension’s guidance on pocket gophers explains that gophers create recognizable fan-shaped mounds as they push excavated soil out of underground tunnels.
The opening is commonly plugged after the soil is pushed out.
That’s an important clue. Homeowners sometimes assume a gopher hole should look like a large open tunnel. In reality, you may see several fresh piles of dirt and struggle to find an entrance at all.
Early Bird Pest Control also identifies gopher mounds in yards and gardens as a common sign of Arizona rodent activity.
What Does a Gopher Mound Look Like?
University of Arizona Extension describes pocket gopher mounds as fan, crescent or horseshoe shaped. There may also be a small plug of soil where the animal closed the lateral tunnel it used to push dirt to the surface.
Fresh mounds suggest current digging or feeding activity.
You may also notice:
- Several mounds appearing in a line or loose pattern
- New soil appearing overnight
- Plants suddenly wilting or disappearing
- Damage around irrigated lawn or garden areas
- Raised or disturbed soil above underground tunnels
Pocket gophers feed on plant material and roots, so landscaping damage can accompany the digging.
Early Bird has additional information about gopher problems in Arizona yards and why allowing an active tunnel system to expand can become a headache for homeowners.
An Open Hole May Point Toward Something Other Than a Gopher
Now suppose the entrance is clearly open.
That changes the diagnostic picture.
University of Arizona Extension notes that if a burrow isn’t plugged, it may belong to a rock squirrel or another animal rather than a pocket gopher.
Again, don’t use that clue by itself. Look at the surroundings.
Do you see an animal using the entrance during daylight? Are there multiple open holes nearby? Is the burrow beneath a wall, rock pile or landscaped slope rather than in the middle of the lawn?
A few minutes of observation from a safe distance can tell you considerably more than poking around inside the hole.
Where Is the Hole Located?
Location is one of the easiest clues homeowners overlook.
A mound moving through irrigated turf suggests something different from an opening tucked underneath a storage shed.
Make note of holes or digging activity found:
- In lawns and irrigated landscaping
- Around garden beds and plant roots
- Along block walls or foundations
- Beneath sheds and outdoor storage
- Near patios and hardscape
- Under thick shrubs or desert landscaping
- Near irrigation equipment or water sources
Pest activity can become more noticeable when landscaping changes. Early Bird explains that construction and disturbance of desert habitat can push Arizona pests toward landscaped residential areas where food, water and shelter are available.
Could the Holes Be From Pack Rats?
Pack rats are common Arizona pests, but they’re usually identified by more than a neat mound of freshly excavated soil.
Look around structures, storage areas and dense vegetation for additional signs of rodent activity.
You might notice nesting material, droppings, gnawing or evidence that something is using a protected area for shelter.
Pack rats, roof rats and mice can also move between outdoor areas and structures. If you’re noticing digging outside along with scratching sounds or rodent evidence around the house, the inspection shouldn’t stop at the yard.
Early Bird provides Arizona pack rat, roof rat, mouse and rodent removal throughout its Phoenix Valley service area.
Could an Insect Be Making the Hole?
Yes.
Not every small hole in Arizona soil is a rodent burrow.
Ants and other insects can excavate soil around nest openings. Ground-nesting insects can also create small individual holes.
Watch for insect traffic before assuming something larger is underground.
Numerous small openings surrounded by fine loose soil are very different from a gopher tunnel system pushing larger mounds onto the lawn.
Arizona homeowners deal with plenty of both. Early Bird’s Arizona pest control services cover rodents as well as ants, scorpions, spiders, cockroaches, bees, wasps and other common desert pests.
What Does the Soil Disturbance Tell You?
Fresh soil usually matters more than old soil.
A weathered hole with compacted dirt, leaves or debris around the entrance may no longer be active. Fresh, loose soil appearing repeatedly suggests something is still working underground.
Look again the next morning.
If yesterday’s mound is followed by another several feet away, you’re probably seeing an active burrow system rather than an isolated hole.
Don’t immediately flatten all the evidence. The direction and progression of the new mounds may help identify the problem.
Look for Plant Damage Too
If the digging is concentrated around landscaping, inspect the plants.
Are roots being disturbed? Have young plants disappeared? Is a section of turf suddenly loose or declining?
Pocket gophers spend most of their lives underground and feed heavily on plant material. According to University of Arizona Cooperative Extension, they commonly occupy areas where suitable soil and food sources such as roots and other vegetation are available.
That makes irrigated residential landscaping a potential target even though the surrounding Phoenix environment is desert.
Does the Size of the Hole Matter?
Yes, but use it as supporting evidence rather than your entire identification method.
Soil can collapse around burrow openings. An older opening can become enlarged. Different species can also use abandoned burrows.
A homeowner saying, “It’s about three inches wide,” is useful.
A homeowner saying, “It’s about three inches wide, open, beneath a wall, with no dirt mound and I’ve seen a squirrel nearby,” is much more useful.
Should You Fill the Hole and See What Happens?
Before you do, document it.
Take a picture of the hole, surrounding soil and nearby landscaping. If there are tracks, droppings or plant damage, photograph those too.
Then watch for new activity.
If you don’t know what made the burrow, avoid putting pesticides, bait or traps into a random hole. Different pests require different control methods, and you don’t want to treat the wrong animal.
Arizona Burrowing Pest FAQs
What do gopher holes look like in Arizona?
Pocket gophers commonly create fan, crescent or horseshoe-shaped mounds of loose soil. The burrow opening is often plugged, so an obvious open hole may not be visible.
What does it mean if the hole stays open?
An open entrance may indicate a different burrowing animal. University of Arizona Extension notes that an unplugged burrow could belong to a rock squirrel or another animal. Additional signs are needed for a confident identification.
Why are fresh dirt piles appearing across my yard?
Repeated fresh mounds can indicate an active underground burrow system. Gophers push excavated soil to the surface as they extend or maintain their tunnels.
Can gophers damage an Arizona yard?
Yes. Their tunneling can disturb soil and landscaping, while feeding activity can damage roots and plants. Problems can become more noticeable in lawns, gardens and irrigated areas.
Are all small holes in an Arizona yard caused by rodents?
No. Ants and other ground-nesting insects can also produce holes and disturbed soil. Watch the opening for activity and consider the size, soil pattern and surrounding evidence.
Who handles gophers and other burrowing pests in the Phoenix Valley?
Early Bird Pest Control provides pest and rodent control for gophers, pack rats, roof rats, mice and other Arizona pests throughout Phoenix and surrounding communities.
Before You Call Pest Control, Take a Few Good Pictures
If something is digging holes in your Arizona yard, don’t rush to erase the evidence.
Photograph the mound. Check whether the entrance is open or plugged. Look at the shape of the displaced dirt, nearby plant damage and where the activity is occurring. Then check again the next day for fresh digging.
Those details can make it much easier to determine whether you’re dealing with a gopher, another rodent or something else entirely.
