40 California Agricultural Extension Circular 138 mice, and steps taken at once to check the mice if necessary. Otherwise, clean cultivation in orchards and the removal of grass and weeds along fences, about farm buildings, and around piles of lumber, will reduce the shelter and food for these animals. Meadow mice may be controlled either by traps or by poison. For small numbers the best plan is to use mousetraps baited with oatmeal, rolled oats, or bits of apple or carrot or other root vegetables, and set with the triggers of the traps across the runways. The traps will then be effective on mice run- ning in either direction along the surface paths. Sometimes unbaited traps will suffice. Traps should be visited at frequent intervals, since these mice are active by day as well as at night and the efficiency of individual traps is in- creased by frequent attention. When meadow mice are present in large numbers or over a large acreage, it is necessary to use poison. Formerly strychnine on alfalfa leaves was em- ployed (formula 8), but recently zinc phosphide on rolled barley or oats or oat groats (formula 7) has been used with success.
