Farmette, they will eat that much and
more.
Shocking how much those little critters can consume!
Look for their feces to find out if you have them. . . you can find pics on google images.
If you can't find any evidence of worms, you might want to consider concocting gadgets to protect your plants.
In the past what worked for me on mice and voles. . . I put down some cut plastic bagging from contractor bags and a yogurt cup or two underneath to create sort of a dome around the plants.
When a critter started walking up the plastic it would collapse and startle them.
Of course, I think they would figure this out eventually. . . but I only had to do this at the end of the season.
Some people put out mouse traps with gummie bears in them.
Also be on the lookout for chipmunks and squirrels. You can put out sunflower seeds etc out elsewhere to keep them away from the mater. . . as long as you're not in a situation where you'll be drawing more critters onto your property.
Good luck!
