what to bait a livetrap with that a woodchuck would like better than sweet potato vines?

What do you suppose they might like better than sweet potato vines that we could bait the live trap with?
carrots?
potatoes?
We don't have anything in the refrigerator that's not in the garden already except carrots and potatoes.
They are vegetarian, correct?

This is the downside to a neighborhood with no dogs...the first time in ten years there have not been a neighbor's dogs barking night and day and running loose....they kept most of the critters away from our gardens.

going to try a nice organic carrot...sliced maybe.

https://en.wikipedia.org/wiki/Groundhog

  Mostly herbivorous, groundhogs eat primarily wild grasses and other vegetation, including berries, bark, leaves, and agricultural crops, when available.[32][29] In early spring, dandelion and coltsfoot are important groundhog food items. Some additional foods include sheep sorrel, timothy-grass, buttercup, persicaria, agrimony, red and black raspberries, mulberries, buckwheat, plantain, wild lettuce, alfalfa, and all varieties of clover. Groundhogs also occasionally eat small animals, such as grubs, grasshoppers, snails, and even bird eggs and baby birds, but are not as omnivorous as many other Sciuridae.[29][35]
