TW: Bedbugs

I normally stay pretty clear of peoples houses for this exact reason. This particular person I am very close to, but they always let whoever they want over to their house. (Not my house, not my business). Welp someone brought bed bugs over into their house, not terribly quite yet, I think it is quite literally only in his bedroom, noticed it earlier, immediately went home to check all of my belongings while he got to deep cleaning the best he could for the night. Weve both been up all night.

I know I don’t have them, I have checked every single surface of my bedroom, have cleaned all of my sheets, and will continue to check the rest of the house tomorrow. I absolutely hate bugs, am very germaphobic I guess the word people use it. Please tell me every precaution I could possibly do ASAP, I do not have a ton of money to spare, but please tell me what I could buy or what I could do to ease my mind during this situation anything would be helpful before I start loosing my mind.

-I have banned everyone I know from being in my car for the next 10 days (besides my brother, and hes already aware of the situation, so he told me he would also be deep cleaning, we are both close to this individual)
-I will be deep cleaning my entire car tomorrow (I normally deep clean it every couple days but tomorrow I will be spending extra time to make sure every single surface is cleaned.)
-cleaned bedsheets, blankets, pillowcases
-checked my bed, room obviously have yet to vacuum though because it is quite loud and people are currently sleeping (so the vacuuming will be done in the morning)

If you have ANY other ideas for cleaning theories, because currently right now im not doing too well. Things in my life keep getting worse and worse and of course this would be the next thing to scare me.
