ORCHARD MOUSE RECOMMENDATIONS— FALL 1963 



Orchard mice can be controlled by placing poisoned baits in mouse trails by 

 hand, broadcasting, or by using the trail builder machine. 



The BROADCAST METHOD is fast and very effective for MEADOW MICE that feed 

 and travel on the surface. A man can hand bait an orchard about as fast as he 

 can walk the tree rows. Forcibly throw a small handful of bait into the matted 

 grass within the drip area of the tree. Be sure to treat both sides of the tree 

 row. Baiting should be done when the grass is dry so the bait will sift through 

 where the mice can readily find it. A hand or tractor-drawn seeder is faster and 

 also does an effective job. The recommended rate of application varies between 

 6 and 10 pounds per acre, depending on density of ground cover and the severity 

 of the mouse infestation. The method is not recommended for controlling pine 

 mice because of their subsurface activities and habits. 



HAND BAITING, although slow and laborious. Is still a good control method 

 for PINE MICE on small acreages. For large acreages, a MECHANICAL TRAIL BUILDER 

 produces good results. Both the Zinc Phosphide Rodenticide-treated apples and 

 the Zinc Phosphide-treated Steamed-crushed Oats should be used for this species. 

 When using the Trail Builder, make parallel applications on each side of the tree 

 within the drip area of the tree. Four to six pounds of bait per acre should be 

 used. When using any poisoned bait, the importance of favorable weather during 

 treatment and for at least two days following cannot be overemphasized!
