>>10095825update, bros.
I did end up capturing him in a jar.
I just kinda forced him into it by cornering him more by putting shoe boxes around him.
I then walked a bit and released him.
I should probably buy mouse traps just in case, I guess, because I really have no idea where he came from. I'll follow this anons
>>10095874 advice and patch up any small holes I see though.
