There are two distinct physical characters which separate Pine and 

 Meadow Mice. The Meadow Mouse has conspicuous eyes and a tail that is 

 twice as long as the hind foot while the Pine Mouse has inconspicuous 

 eyes and a tail the same length as the hind foot. 



Broadcasting of Zinc phosphide treated oats or apple gives adequate 

 control of Meadow Mice but should not be relied upon to control Pine Mice. 

 Where Pine Mice are widely distributed the placement of Zinc phosphide 

 treated apple and oats at five foot intervals in artificial trail systems 

 made by the trail building machine is preferable as it eliminates the 

 search for mouse tunnels. The construction of a good trail is the key 

 to success with the trail builder. This requires a good sod, reasonably 

 moist soil, and a carefully adjusted cutting disc so that the sod is not 

 turned over but merely lifted and dropped back into place. Baiting 

 should be conducted in fair weather and only fresh baits should be used. 



Where Pine Mice occur in isolated colonies, hand placement of Zinc 

 phosphide treated oats or apples in the mouse tunnels will give excellent 

 results. 



The success of any mouse control method can be checked by comparing 

 the mouse population before and several days after the control operation. 

 This can be done by the use of snap traps baited with apple and set at 

 right angles to the trail system. Equal numbers of traps should be set 

 for the same length of time under similar weather conditions.

It has been called to our attention by the Massachusetts Division of 

 Fisheries and Game that under Chapter 131, Section 87, as amended by 

 Chapter 3'+5, Acts of 1963, that a permit will be required to place poison 

 in orchards for the control of mice. Requests for permits must be in 

 writing and must state the specific area involved, bait to be used, and 

 period of time during which such work will be conducted. Approval will 

 only be granted for Zinc Phosphide-treated baits. Applications should be 

 sent to the Director, James M. Shepard, Massachusetts Division of Fish- 

 eries and Game, 73 Tremont Street, Boston, Masslachusetts .
