In this article, you’ll learn how to spot ground squirrel damage and the benefits of expert control. But before implementing control measures, it’s crucial to verify that the damage was caused by a California ground squirrel rather than a tree squirrel, pocket gopher, or mole.
How to Recognize a Ground Squirrel (Size & Behavior)
The California ground squirrel (Otospermophilus beecheyi) is the dominant ground squirrel species found throughout Salinas and most of coastal California. Key identifying characteristics include:
- Size: Adults are 14 to 20 inches long (including a 5- to 9-inch tail) and weigh around 1.5 to 2 pounds.
- Fur Color: Brown fur with gray and white spots on their back, and a lighter belly underneath.
- Key Features: Standing ears, a clear white ring around each eye, and a tail that is less bushy than a tree squirrel’s.
- Escape Behavior: When threatened, ground squirrels always run down into underground holes. Tree squirrels run up trees or fences and never use dirt burrows.
- Daily Routine: They are active during the day, mostly from mid-morning to late afternoon on warm, sunny days.
- Seasonal Habits: They sleep in their shelters during cold winter months. In very hot summer weather, they go inactive for short periods and plug their holes from the inside with dirt.
8 Major Signs Your Home Needs Ground Squirrel Control
Once you know what a ground squirrel looks like, it becomes easier to recognize the problems. Here are some of the major ground squirrel infestation signs you need to watch out for:
1. Multiple Burrow Holes
As ground squirrels build underground homes, they dig wide tunnel networks to protect their colony. Unlike pocket gophers that cover their holes with dirt mounds, ground squirrels leave their entrances wide open so they can dive inside when scared.
Warning signs:
- Open holes about 4 inches wide
- Unplugged entrances with clean edges
- Multiple openings across your yard
- Hole clusters along fences and walls
- Tunnels near garden beds and hillsides
2. Visible Droppings (Feces)
Ground squirrels relax near their burrows. You’ll observe droppings near the small shelters in your garden. This waste releases an unpleasant smell and lures other rodents. Gradually, the bacteria pollute nearby soil and lawn beds.
Warning signs:
- Small droppings shaped like coffee beans
- Smooth, rounded ends on each piece of waste
- Brown color with tiny bits of red, tan, or green
- Neat piles of waste near burrow holes instead of scattered trails
- Fresh dark droppings that turn dull once they dry out
3. Lawn Damage
Ground squirrels eat almost anything, including seeds, fruits, vegetables, nuts, tree bark, and green plants. A small colony can wipe out a garden bed or an entire fruit patch within a few days.
In addition, when these rodents chew a complete ring of bark off a trunk, they block vital nutrients from moving up from the roots. Gradually, this causes main branches or the whole young tree to perish early.
Warning signs:
- Eaten sprouts and seedlings
- Missing fruits and vegetables
- Stripped leaves on low branches
- Chewed bark near tree trunks
- Scattered nut shells near burrows
4. Damage to Water Pipes and Wires
During hot Salinas summers, ground squirrels bite into plastic water lines to get a drink. While this gives them access to water, it creates big problems for you. A leak in water lines wastes water, floods garden beds, and turns the soil into mud. This weakens nearby foundations.
Additionally, if they chew on electrical wires closer to water leaks, it can create dangerous fire hazards.
Warning signs:
- Chewed garden water tubes
- Punctured sprinkler pipes
- Broken sprinkler heads
- Broken plastic valve covers
- Watery, flooded spots in your yard
- Bare or chewed outdoor electrical wires
- Yard lights or pumps suddenly stopping work
- Low water pressure in your sprinklers
5. Chew Marks on Outdoor Furniture
Ground squirrels mostly stay underground, but they chew on wooden pieces and furniture. They chew to trim down their front teeth, which never stop growing. However, this activity on structures opens gaps where rainwater can enter and cause wood rot.
Also, the enlarged holes along their shelters or deck edges allow other pests easy access to quiet areas under your home, which can cause more damage.
Warning signs:
- Teeth marks on wooden fence posts and decks
- Gnawed siding on sheds or low house trim
- Chewed balcony furniture
- Torn plastic or metal mesh along crawl space vents
- Damaged outdoor garbage bags and storage bins
6. Structural Damage to Property
When ground squirrels dig tunnels, they remove soil and leave empty pockets underneath your property. Over time, these gaps collapse, causing heavy concrete surfaces to shift, crack, and sink.
In addition, when squirrels dig near house supports, they remove the dirt holding up your home, causing foundations to shift or crack. On sloped yards, rainwater fills their open burrows and washes away loose soil, making the ground sink even faster.
Warning signs:
- Cracked driveways
- Uneven sidewalks
- Sunken patios
- Tilting retaining walls
- Sinking lawn features
- Gaps along concrete joints
7. Weird Noises and Bad Smells
Unlike tree squirrels, ground squirrels build their nests underneath homes and in crawl spaces. You’ll hear clear noises such as chewing, scratching, or running from under floorboards, low wall gaps, and outdoor decks.
These rodents also leave urine or feces in these areas, releasing strong, unpleasant smells. The odors are worse when a squirrel is trapped and is dead. Their decaying body produces the worst odor, ruining indoor air quality.
Warning signs:
- Daytime scratching or scurrying noises under floors
- Chewing sounds coming from lower wall gaps
- Unexplained foul odors coming from crawl spaces
- Dark urine stains along concrete foundations or floor edges
- Sudden rise in the number of flies near low home vents
8. Increased Number of Squirrels
One of the simplest ways to recognize the need for ground squirrel control is to notice the population. You will see a visible increase in ground squirrel sightings near your yard.
Also, since California ground squirrels are active during the day, seeing them constantly is a direct sign of a growing colony. This makes them dig more holes in the yard.
Warning signs:
- Several squirrels standing tall on small dirt piles
- More movement outside during warm sunny mornings
- Groups resting in the sun on rocks, fences, or low stone walls
- Squirrels running into ground holes when you walk outside
- Seeing squirrels daily along fence lines and open yard areas

Ground Squirrel Prevention Tips
As mentioned previously, DIY methods rarely help control ground squirrels. Instead, we suggest homeowners use them as a maintenance strategy. You can follow these steps after specialists complete ground squirrel removal treatment at your site:
- Remove Food Sources:
Pick up fallen fruit from trees, secure outdoor trash cans, and clean up spilled birdseed daily. - Block Access to Burrows:
Install wire mesh (hardware cloth) buried at least 6 to 12 inches deep along garden beds, decks, and shed bases. - Cut Low Vegetation:
Keep tall grass short and trim low-hanging shrubs so returning squirrels have fewer places to hide. - Seal Entry Gaps:
Check open pipe ends, cover crawl space vents with heavy metal mesh screens, and seal gaps near foundations.
