<*3*/ Fig. 18. Oregon or Belding ground squirrel of northeastern California. Head and body about 8'/2 inches, tail, IVi inches. soft earth around burrows. About 1 table- spoon should be scattered at each spot to cover 1 to 2 square feet; 1 quart pro- vides 30 to 35 baits. For poisoned dandelion greens, use formula 5 but substitute 5 gallons (bulk) of freshly cut green dandelion plants with roots, or fresh chicory, for the oats. Water cress or alfalfa leaves are less satisfac- tory. Two or three pieces of greens are put into each burrow; this does not en- danger birds. Carbon disulfide may be used to gas burrows of this squirrel as described for the California ground squirrel. Around mountain cabins and in some localities in eastern California and the deserts it sometimes becomes necessary to control other species of ground squir- rels, and also chipmunks. In this group are the golden-mantled ground squirrel (Citellus lateralis), the antelope ground squirrel or chipmunk (Citellus leucurus), and the small striped chipmunks (Eu- tamias). The general methods described for control of the California ground squir- rel (pages 27-33) will usually prove sat- istfactory. To rid a small area of a few squir- rels, as about a mountain cabin, the ani- mals may be shot or trapped. Ordinary wooden rat traps can be used, but care must be taken, when removing dead ani- mals, to see that fleas or ticks from them do not get on the operator as they can carry infectious diseases from diseased animals to man. Gloves should be worn, and clothing should be treated immedi- ately afterward with fly spray. Poisoned bait should be used only when it can be placed on the ground, under shelter of boards or logs, where birds or pets cannot reach it. Anticoagulant bait may be of value in such places. (35)
