Why Ground Squirrels Are a Serious Property Concern
Ground squirrels are more than just a nuisance. Their burrowing can create real damage around residential, commercial, agricultural, and municipal properties. Over time, their tunnels can weaken soil around slopes, walkways, foundations, fences, retaining areas, irrigation systems, and landscaped sections.
They can also damage food-bearing plants, ornamental plants, young trees, and garden areas. In addition, ground squirrels may carry fleas and other health-related concerns, which makes professional control especially important when they are active near homes, schools, parks, or public spaces.
Poison-Free Ground Squirrel Control With the TerraTrap GS System
Lenz Pest Control offers poison-free ground squirrel control for customers who want effective results without relying on rodenticide bait. This is especially important for properties with pets, children, wildlife, birds of prey, or sensitive outdoor areas.
As the inventor of the TerraTrap GS System, Lenz Pest Control provides a specialized trapping solution designed specifically for ground squirrels. Unlike standard traps, the TerraTrap GS uses a rock-like housing that mimics a natural ground squirrel den, making it more familiar and approachable for these cautious burrowing pests.
This system is:
- Poison-free
- Designed specifically for ground squirrels
- Self-resetting for repeated activity
- Built to blend into outdoor environments
- Helpful for residential, commercial, ranch, and open-space properties
- A strong option for customers concerned about secondary poisoning risks
Because the TerraTrap GS System is designed around actual ground squirrel behavior, it gives property owners a more specialized solution for a pest that can be difficult to control with standard methods.
The Trap Cover

The TerraTrap GS, patent pending, was invented in California by seasoned pest control operators. It solves the challenge of California Ground Squirrel control:
Ground Squirrels are much more likely to approach the trap that mimics the natural environment they are used to. The design encourages tunneling into the trap, while the appearance of a rock does not alarm the notoriously timid pests.

Humane Control
The system is powered by Goodnature's A18 Trap. The A18 is an automatic trap that kills instantly and humanely. Then the dead squirrel is released to be collected or scavenged by animals.
Scavengers in the area will quickly adapt to checking the trap, clearing it out for you, and reducing labor significantly.
Our Ground Squirrel Control Process
Inspection
Step 1: Inspection
We start by inspecting the property for burrow openings, active runways, feeding damage, landscape damage, and signs of current ground squirrel activity.
Step 2: Control Plan
Next, we recommend a targeted plan based on the size of the property, level of activity, location of burrows, and surrounding risk factors such as pets, children, livestock, wildlife, slopes, gardens, or public access areas.
Step 3: Poison-Free Trapping
When appropriate, we use poison-free trapping options, including the TerraTrap GS System, to help control active ground squirrel populations without relying on toxic bait.
Step 4: Ongoing Monitoring
Ground squirrels can return from nearby open spaces, fields, hillsides, or neighboring properties. Therefore, ongoing monitoring and maintenance may be recommended for long-term contr
