Testing of Ramik for control of orchard mice was begun in 1972 in New York. By 1974 there were many test locations all over the Northeast, and by 1975 tests were conducted all over the country. Analyzing the results of some of the early testing suggested some refinements of application technique and formulation. These changes were made to better adapt Ramik to the conditions found in the orchard, and to make it more attractive to the voles. Some of the parameters examined are outlined below:

1. Bait flavor

2. Weather effects on the bait

3. Pellet size

4. Toxicant concentration

5. Method of placement
a. Bait stations
b. Hand placement vs. machine application
c. Trail builder application
d. Band vs. broadcast treatments
e. Aerial vs. ground application

6. Timing of application
