What’s Digging Holes in My Arizona Yard? How to Identify the Likely Pest
You walk outside in the morning and there’s a new hole next to the patio. A pile of dirt has appeared beside the lawn. Or several openings suddenly show up along the edge of the yard.
Something has been digging.
The tempting move is to look at the hole, guess “gopher” and start treating it. That’s not always a good idea. Several Arizona animals use underground burrows, and the opening itself is only one clue.
If you’re trying to identify holes in an Arizona yard, look at the entire scene: the shape of the opening, displaced soil, whether the hole is open or plugged, where it appears, nearby plant damage and whether you’re finding one hole or an expanding network.
Early Bird Pest Control provides rodent and gopher control throughout the Phoenix Valley, including Scottsdale, Paradise Valley, Goodyear, Avondale, Buckeye, Peoria and surrounding Maricopa County communities.
Don’t Identify a Yard Pest by Hole Size Alone
“The hole is about two inches wide. What made it?”
Unfortunately, that’s usually not enough information.
Hole dimensions can vary with the animal, soil conditions, age of the burrow and whether the opening has been disturbed. Loose desert soil can also collapse around an entrance and make it look larger than it originally was.
Instead, take note of four things before disturbing the area:
- Where the hole is located
- Its approximate size and shape
- How the displaced soil is arranged
- What other signs appear nearby
Those clues can make identification much easier.
Fan-Shaped or Crescent-Shaped Dirt Mounds? Look More Closely for Gophers
Gophers are one of the obvious suspects when fresh dirt starts appearing across an Arizona lawn or landscaped area.
According to the University of Arizona Cooperative Extension, Arizona has three species of pocket gophers. They spend most of their lives in underground burrow systems.
The dirt pattern is particularly useful.
As a pocket gopher excavates its tunnel, it pushes soil to the surface through a lateral opening. This can produce a distinctive horseshoe, crescent or fan-shaped mound. The opening is often plugged with soil rather than left as an obvious open entrance.
So if you’re seeing fresh mounds but wondering, “Where’s the actual hole?” that can be an important clue.
Early Bird Pest Control also identifies gopher mounds in yards and gardens as a common sign of rodent activity.
Are Plants Disappearing or Being Damaged Near the Mounds?
Look at what’s happening to the landscaping too.
Pocket gophers feed primarily on plant material and roots. Damage around garden beds, turf and landscaped areas can accompany underground activity.
You may notice plants declining unexpectedly, damaged root systems or soil disturbance spreading through an irrigated section of the yard.
Early Bird has additional information about preventing gopher problems in Arizona yards, including the damage their tunneling and feeding can cause to landscaping.
Open Burrows Can Point Toward a Different Animal
Now compare that with an obvious open hole leading into the ground.
Ground squirrels, for example, create burrows with visible entrances rather than the characteristic plugged mound associated with pocket gophers.
The University of Arizona Extension recommends looking at more than the entrance itself when identifying burrowing rodents. Burrow arrangement, tracks, droppings, feeding damage and actual animal sightings can all help narrow things down.
If you can safely observe the area from a distance during daylight, you may even see what’s using the burrow.
Don’t stick your hand into it. Arizona has plenty of wildlife capable of turning that experiment into a very bad afternoon.
Where in the Yard Is the Hole?
Location can be surprisingly useful.
A series of soil mounds moving through irrigated turf or a garden tells a different story from an opening tucked underneath a shed.
Pay particular attention to holes:
- Along foundations or block walls
- Under sheds and storage areas
- Near irrigation and landscaped beds
- Under dense shrubs or vegetation
- Beside patios and hardscape
- Near wood piles or stored materials
Rodents generally look for some combination of food, water and shelter. Arizona landscaping can provide all three, particularly around irrigated vegetation.
Recent landscaping can also expose activity that homeowners hadn’t noticed before. Early Bird explains that Arizona landscaping projects can disturb existing pest habitat, sometimes pushing rodents and other pests into more noticeable locations.
What About Pack Rats?
Pack rats are common enough in Arizona that they’re worth considering, but a random dirt mound in the middle of your lawn doesn’t automatically mean you have one.
Look for other evidence.
Pack rats, also called woodrats, are known for building nests or middens from available material. Around homes, activity may be associated with sheltered spaces, vegetation, stored materials and other protected areas.
If you’re seeing droppings, gnawing, nesting material or signs of rodents around the structure in addition to ground disturbance, the investigation should extend beyond the hole itself.
Early Bird provides information about Arizona pack rats and offers removal services for pack rats, roof rats, mice, gophers and other rodent problems.
Could It Be an Insect Instead of a Rodent?
Absolutely.
Not every hole in an Arizona yard was excavated by something furry.
Ants and other ground-dwelling insects can create small openings accompanied by loose soil. Certain solitary bees and wasps also nest in the ground.
This is where scale and surrounding activity matter. Numerous small openings with insect traffic are a very different problem from a large underground tunnel system pushing substantial amounts of soil onto the lawn.
Watch the opening for a few minutes from a reasonable distance. You may solve the mystery without touching anything.
Is It One Hole or a Growing Pattern?
Take a picture when you first notice the problem.
Then look again the next morning.
A single old hole that never changes may be inactive. Fresh soil appearing overnight, new mounds developing across the yard or additional openings showing up nearby suggest current activity.
That pattern can also help a pest control professional determine which areas are active rather than relying on older signs.
Should You Fill the Hole to See If It Comes Back?
It can be useful to know whether a burrow is active, but don’t start collapsing or filling holes until you have some idea what you’re dealing with.
First photograph the opening, soil mound and surrounding area. Note fresh tracks, droppings, plant damage or other evidence.
If you aren’t confident about the animal, an inspection is a better next step than randomly placing traps or pest-control products around the yard.
Arizona Yard Hole FAQs
What do gopher holes look like in Arizona?
Pocket gophers commonly leave fan, crescent or horseshoe-shaped soil mounds. The burrow opening itself is frequently plugged with soil, so you may see a fresh mound without an obvious open hole.
Does a large open hole mean I have a gopher?
Not necessarily. Gopher openings are commonly plugged. Ground squirrels and other animals may leave more obvious open burrow entrances. Identification should include the soil pattern, location and other signs.
Why are new holes suddenly appearing after landscaping?
Excavation, irrigation changes, removal of vegetation and other landscaping work can disturb existing habitat and make pest activity more noticeable. Watch for continuing activity rather than assuming every newly exposed hole is a new infestation.
Can burrowing pests damage irrigation?
They can. Early Bird notes that gopher tunneling can disturb landscaped areas and potentially damage irrigation systems. If mounds are appearing around irrigation lines, have the activity identified before the problem spreads.
Who handles gopher and rodent problems in the Phoenix Valley?
Early Bird Pest Control provides rodent and pest control for gophers, pack rats, roof rats, mice and other pests throughout Phoenix, Scottsdale, Paradise Valley and West Valley communities.
Take a Picture Before You Disturb the Evidence
If something is digging up your Arizona yard, resist the urge to immediately rake the mound flat.
Take pictures. Look at the mound shape. Check whether the entrance is open or plugged. Note nearby landscaping damage and see whether fresh soil appears somewhere else the next day.
Those details can tell you considerably more than hole size alone.
If the digging continues, contact Early Bird Pest Control for help identifying and treating gophers, rodents and other Arizona pests in Phoenix, Scottsdale, Paradise Valley, Goodyear, Avondale, Buckeye, Peoria, Surprise and surrounding communities.
