Ground squirrel traps fall into two main categories, lethal and live-catch, and choosing the right one depends on your property, local laws, and how many squirrels you’re dealing with. Trapping is one of the more targeted control methods available because you can place traps precisely at active burrows and avoid broadcasting chemicals across your yard or pasture. Here’s what you need to know to trap effectively and legally.
Types of Ground Squirrel Traps
Lethal traps include box traps, tunnel traps, Conibear-style body-gripping traps, and self-resetting models like the Goodnature A18. These traps kill quickly on contact, which means you don’t have to deal with a live animal afterward. Box and tunnel traps enclose the mechanism inside a housing, which helps shield pets and children from the trigger. Conibear traps are spring-loaded squares that snap shut when an animal passes through, and they’re highly effective but more exposed. The Goodnature A18 is a newer option that resets itself automatically using a compressed gas cartridge, allowing it to dispatch multiple squirrels without being manually re-set each time.
Live-catch traps (sometimes called cage traps) capture the squirrel inside a wire enclosure without injuring it. The main advantage is that if you accidentally catch a non-target animal, like a songbird or a neighbor’s cat, you can release it unharmed. The significant downside is what happens next: in most states, relocating a trapped ground squirrel is illegal. California Fish and Game Code prohibits it outright, and New York bans moving any trapped animal off your property. That means live trapping almost always requires euthanizing the animal on-site, which many homeowners aren’t prepared for.
Where to Place Traps
Set traps directly on the ground near active burrow openings or along visible runways, the packed-dirt paths squirrels use repeatedly between burrows and feeding areas. You’ll get the best results by identifying which burrows are currently active. Fresh digging, small mounds of loose soil, and droppings around the entrance are reliable signs. Placing a trap at an abandoned hole is a common reason trapping fails.
Orientation matters too. Position the trap so the entrance faces the burrow opening or sits across the runway. Ground squirrels are cautious but habitual. If the trap sits in their natural travel path, they’re far more likely to enter it than if it’s placed a few feet off to the side.
Best Time of Year and Day
Ground squirrels are daytime animals, most active from midmorning through late afternoon, especially on warm, sunny days. That’s when traps will see the most traffic. Set them in the morning and check them by evening.
Seasonally, trapping works from late January through early October. During late fall and winter (roughly late October through December), most ground squirrels are underground and inactive, making trapping essentially useless during those months. Spring and early summer tend to be the most productive period because squirrels are actively foraging above ground and young animals are dispersing from their birth burrows into new territory.
Pre-Baiting for Better Results
One of the most overlooked steps in ground squirrel trapping is pre-baiting: placing food in and around the trap for several days before actually setting the trigger. The idea is to let squirrels get comfortable eating from the trap while it poses no threat. Research from UC Davis found that repeated exposure to bait dramatically increases how much squirrels consume. After two pre-bait applications, squirrels ate more than twice as much. After four applications, they consumed over four times as much. The same principle applies to trapping: a squirrel that has safely eaten from a trap three or four times will walk confidently into it on the day the trigger is live.
Good pre-bait options include walnuts, almonds, oats, or pieces of melon and other fruit. Place the bait inside and around the trap entrance, and leave the trap mechanism wired open or disabled. Two to four days of pre-baiting is a reasonable timeline for most situations.
Protecting Pets, Children, and Non-Target Wildlife
Lethal traps pose a real risk to anything that triggers them, so placement and sizing are your main safety tools. Restricting traps to burrow openings of four inches in diameter or less helps exclude larger non-target animals while still catching ground squirrels. Enclosed designs like box and tunnel traps add another layer of protection by hiding the kill mechanism inside a housing that’s too small for a dog’s paw or a child’s hand.
Removing traps at dusk protects nocturnal animals like skunks, opossums, and raccoons that might investigate the bait overnight. If you’re trapping in an area with foot traffic or pets, avoid open-jaw Conibear traps set above ground. They’re effective but unforgiving to anything that stumbles into them. In those settings, enclosed lethal traps or live-catch cages are safer choices.
Legal Rules You Need to Know
Trapping regulations vary significantly by state and sometimes by species. In California, relocating ground squirrels is flatly prohibited, so live trapping means euthanizing on-site. New York takes a similar stance: it’s illegal to move any trapped animal off your property, and the state requires a licensed Nuisance Wildlife Control Operator to handle relocation tasks. New York also distinguishes between species. Red and flying squirrels can be taken if they’re a nuisance, but gray, black, and fox squirrels require a DEC permit unless they’re actively damaging property. If you take a squirrel during a closed hunting or trapping season, the carcass must be buried or cremated immediately.
Before setting any trap, check your state’s wildlife agency website for species-specific rules, season dates, and permit requirements. Some jurisdictions also regulate trap types, banning certain body-gripping traps or requiring minimum check intervals (how often you must inspect a set trap). Getting this wrong can result in fines, so ten minutes of research is worth it.
Handling and Disposal
Ground squirrels can carry fleas that transmit plague, particularly in the western United States. This isn’t theoretical: plague cases linked to ground squirrel fleas are reported in California, Oregon, and other western states every few years. When handling a dead squirrel, wear gloves and avoid direct skin contact. Place the carcass in a sealed plastic bag for disposal in your regular trash, or bury it at least a foot deep. If you notice a sudden die-off of squirrels on your property (multiple dead animals you didn’t trap), contact your local health department, as this can signal active plague in the colony.
For live-catch traps, approach slowly and cover the cage with a towel or blanket to calm the animal before handling. Keep your fingers away from the mesh. Even a small ground squirrel can deliver a painful bite, and any wild rodent bite warrants a call to your doctor.
How Many Traps You Need
A single trap at one burrow will catch the occasional squirrel, but ground squirrels are colonial animals. A moderate infestation might involve dozens of active burrows spread across a yard or field. For meaningful population reduction, plan on setting multiple traps simultaneously, ideally one at each active burrow entrance in the area you’re targeting. Start with a count of active burrows, then match your trap numbers accordingly. For a backyard with five or six active holes, five or six traps is reasonable. For larger properties or agricultural land, you may need 20 or more traps rotated across different sections over several weeks.
Check traps at least once daily, both to dispatch or remove captured animals promptly and to re-bait and reset. Traps left unchecked attract scavengers, create odor problems, and in many states violate mandatory check-interval laws. Consistent daily attention over two to three weeks will do far more than leaving a single trap out for months.
