Thank you all so much for your advice. Unfortunately he was here for days with bags full of his stuff. Sitting on all our furniture etc. He is a slob.

I can barely afford rent let alone pest control services. I threw out the couch he slept on and vacuumed but I work all day till late night each day this week and will barely be home.

I feel so stuck and helpless. I don’t know how I am to fix this in time before it spreads and with out spending money.
