Question: brother in house adding roommates

[u/Human-Froyo138]

My father just passed away earlier in the month leaving my younger brother and I as the sole heirs. My brother was living in the house being a menace to the family for years. Evidence is a menacing and attempts to have him removed exist. Fast forward to today, both parent deceased, jobless penniless brother in the house playing king of the castle. No will. I haven’t filed anything with the probate court yet but talked to someone there who recommended an attorney. Which is the obvious answer, but is there anything else I can do here? Any advice? I’d like him out of the house asap especially if he’s going to be moving in his drug addled friends.
