How do I know it is a gopher and not a mole?
Gopher mounds are fan-shaped or horseshoe-shaped, built of fine loose soil, and often have a plugged hole off to one side. Moles push up rounder, volcano-style mounds or raised surface ridges. A technician confirms the animal before setting any trap.
The distinction matters because trapping methods and placement differ by animal. A technician looks at the mound shape, the soil texture and whether the tunnel is open or plugged.
If you are unsure, take a photo of a fresh mound and the ground around it before you flatten anything, and describe what damage you are seeing when you call.
Why do gophers dig all year in Los Angeles yards?
Gophers dig wherever soil stays workable and roots keep growing. UC IPM says irrigated lawns, beds and gardens offer good digging conditions all year, so mounds can appear in any month. On non-irrigated ground, mound activity tends to peak in winter and spring when the soil is moist.
This is a dry-summer, wet-winter climate. At the downtown climate station, July and August each average under 0.05 inch of rain, so unwatered ground bakes hard and gopher activity there slows down. Wherever sprinklers or drip lines keep soil damp, the same animals can dig through the dry months.
That is why the animal can seem less seasonal in a Los Angeles yard than the calendar suggests. The first wet-season storms soften unwatered ground, and from winter into spring mounds show up in places that were quiet in August.

What can gophers damage besides the lawn?
Gophers eat roots, bulbs and the lower stems of garden plants, and their tunnels can undermine soil and ground cover, cut irrigation lines and leave hollows that make walking uneven. The visible mounds are only part of the damage, and a plant that tips over may have been eaten from below.
Vegetable beds, roses, ornamental shrubs and young trees are common targets because they are watered and have tender roots. A mound beside a retaining wall or patio edge can also mean a tunnel running below it.
If a mound sits close to a foundation, a pool deck or a retaining wall, mention that when you call. The technician may suggest a different approach near the structure and will tell you if they see signs the soil is already shifting.
- Flatten fresh mounds so new ones are easy to identify
- Note which beds or lawn areas are hit and which are untouched
- Mark irrigation lines before the visit so traps and probes avoid them
- Keep pets and children away from open burrows and set traps
Can I handle gophers myself with store-bought products?
You can try traps from a hardware store, but results depend on finding the main burrow, and misplaced traps are the usual failure. Gimmick products and flooding a tunnel are not the method UC IPM describes. A technician with a probe finds the right tunnel first and tells you when a second animal is the cause.
The most common reason a do-it-yourself attempt fails is placement: traps set in a side tunnel or a plugged lateral are ignored. If you try it yourself, read the label on whatever you buy and keep it away from pets and children.
Calling a technician makes the most sense when the damage is spreading, when you do not know where the main tunnel runs, or when a slope or retaining wall makes digging unsafe.
