User Question: What can I do to keep field mice out of my composter?
As seasoned composting enthusiasts know, field mice seek the warmth and food in composters during winter. While they don't harm the composting process—and their activity can even accelerate decomposition—it's unsettling to disturb them when accessing your bin.
These rodents typically nest at the bottom of the composter, which is often their entry point. For open-bottom units, install a sturdy wire mesh floor with fine mesh size, extending it up the sides. This works best on square composters compared to round or conical ones and proves highly effective based on years of practical experience.
Avoid adding meat or fish scraps to prevent attracting them—rodents can't resist these temptations.
Finally, encourage neighborhood cats to patrol the area as a natural deterrent.
