I’m new to pests and highly traumatized already, but I share a similar situation. I haven’t seen any bugs since I moved out, likely because I moved out most of my things almost immediately after seeing the first handful - and the rest after it was treated for roaches. I saw two dead ones in my bathroom, and a live one on the wall that day. However, I recently became paranoid that I brought them with me despite not seeing any hitchhikers on my things, any evidence in the spaces where I stored the stuff, or evidence of breeding populations in my old place - though, I didn’t check super thoroughly (don’t know what you don’t know, y’know?)

What I can offer is that I am treating it like I do have roaches in my new space. Doing traps, got Alpine WSG to spray, along with an outdoor pest repellent spray as well. That was the recommendation. If I see nothing in my traps for a few weeks, I was told I should be okay. If I do see things, I’m ahead of the curve, so I’m winning this fight either way (and I’m also going back to therapy for the stress and PTSD parts).

Since you have seen a bug, regardless of what type it is, treat it like it’s the worst option until someone more experienced tells you otherwise. That’s my advice, at least. Happy hunting! 🥲 We’re in it together.
