Besides the differences in their physical characteristics, rats
and mice are significantly different in many other ways. Because
rodent control efforts will be most successful when based on an
understanding of the pest itself, it is important to know the
differences between these two rodents. For example, one of the
most critical differences in behavior between mice and rats are
that of curiosity vs. caution. The rat is very cautious and will
not readily approach new items in its path until it has had time
to get used to its presence. Thus, prior to setting rat traps,
unset traps should be placed in the rat's path. Mice, on the
other hand, are very curious and will investigate new things.
Thus, if mice are not caught within the first days of trap
placement (using set traps), the trap is likely in the wrong
place and should be moved. Other differences include: Living and

on almost anything. - Although they rarely burrow, they will
