Gophers and moles are small burrowing mammals that can cause significant damage to gardens and lawns in the Greater Los Angeles area. While they may seem similar at first glance, these two pests differ in their behavior, diet, and the type of damage they inflict on residential properties.
Gophers (Thomomys spp.)
Herbivorous rodents that feed on plants, roots, and bulbs. They create extensive tunnel systems beneath lawns and gardens, resulting in unsightly mounds and damaged vegetation.
Moles (Scalopus aquaticus)
Insectivores that primarily feed on earthworms, grubs, and other soil-dwelling insects. While they also create tunnels, moles are typically more interested in finding food rather than eating plants.
Both pests can be difficult to manage due to their underground lifestyles, but with the right prevention and treatment methods, homeowners can regain control of their yards.
Why Are Gophers and Moles Common in the Greater Los Angeles Area?
The warm, mild climate of Los Angeles and its surrounding areas creates an ideal environment for gophers and moles to thrive. Factors contributing to their prevalence include:
- Favorable Soil Conditions: The loose, well-drained soils of Southern California make it easier for gophers and moles to dig extensive tunnel systems.
- Abundant Vegetation: Many Los Angeles homes have lush gardens, lawns, and landscapes that provide an ample food source for gophers.
- High Insect Populations: Moles are drawn to areas with high populations of earthworms, grubs, and other insects that they feed on.
Signs of a Gopher or Mole Infestation
Detecting an infestation early can help prevent extensive damage to your property. Here are the key signs to look for:
- Gopher Mounds: Gophers create fan-shaped mounds of dirt, typically with a visible plug or hole where the dirt has been pushed to the surface. These mounds are often scattered across lawns and gardens.
- Mole Tunnels: Moles leave behind raised ridges on the surface of the soil, indicating shallow tunnels just beneath the ground. These ridges often crisscross through lawns, creating unsightly bumps and hills.
- Damaged Plants: Gophers feed on the roots and bulbs of plants, causing them to wilt or die. You may notice that plants seem to be pulled into the ground, or entire sections of your garden are destroyed.
- Soft or Sinking Ground: The extensive tunneling activity of both gophers and moles can weaken the soil structure, leading to soft spots or areas where the ground feels unstable.
