HOW TO GET RID OF GROUND SQUIRRELS

Damage and Damage Identification

Burrowing activities, particularly those of the California and Belding ground squirrels, weaken levees, ditch banks, and earthen dams, and undermine roadways and buildings. Burrows can also result in loss of irrigation water by unwanted diversions, and in natural habitats they may cause accelerated soil erosion by channeling rain or snow runoff.

Burrow entrances in school playgrounds, parks, and other recreational areas are responsible for debilitating falls, occasionally resulting in sprained or broken ankles or limbs. Burrows in horse exercising or jumping arenas or on equestrian trails can cause serious injuries to horses and to their riders if thrown.

Legal Status

Most species of ground squirrels are generally regarded as pests and, as such, are not protected. Local laws or regulations should, however, be consulted before undertaking lethal control.

Be aware that several of the numerous ground squirrel species are on the threatened or endangered species lists. Any control of pest species must take into consideration the safeguarding and protection of endangered ground squirrels and other rodent species.

Damage Prevention and Control Methods

Exclusion
Limited usefulness and costly.

Habitat Modification
Flood irrigation and deep tillage may help discourage ground squirrels. Eliminate brush, rock piles, and old unused farm machinery that serve as harborage for the California ground squirrel.

Repellents
None are very effective.

Toxicants
Zinc phosphide. Anticoagulants ( diphacinone and chlorophacinone ). Cholecalciferol (state registration only for rock squirrels).

Fumigants
Aluminum phosphide . Gas cartridges.

Trapping
Box-type traps (kill and live catch). Conibear ® traps.

Shooting
Limited effectiveness.

Other Methods
Burrow ripping following control.
