[Unexpected guests on my mint? 11/15/2021 -Rambling]

I've had a mint plant I've kept inside my home for about a month now, it was originally outside my garden. I moved it to the windowsill in my room because it wasn't doing well; it was quite brown and unhappy. I watered it as well and it sprung back to life!... Only for it's happy green leaves to disappear the next day. Turns out, there's two MASSIVE inchworms eating my mint!!! In my room!! I'm going to have to put this plant outside again, hope the moths like winter weather!
