Bug from a package
My fiancee ordered a package of clothing that shipped in a paper envelope from China. She opened it on top of a white blanket on our couch, and about ten minutes later noticed this bug on the blanket near where she opened it. She thought it was a tick (we've been in the woods with our dogs within the past few days, but we tick checked the dogs when we got home and found none). She picked it up and said it was very sluggish and seemed half-dead. She squished it and said that some pus-like, vaguely pinkish stuff came out, but no dark brown or bright red blood. From memory, she said the body was more roundish than totally flat like an apple seed, but she's not sure. She thinks she remembers antenna but she's not positive. Thank god she happened to take pictures, they're not very good pictures, but they're all we have because she washed the corpse down the kitchen sink. My fiancee, the packaging, and all the contents of the package stayed sitting on our couch for about an hour and didn't move from there until I got home. I tried on one of the shirts from the package in the living room. She asked me to tick-check her hair but I didn't find anything. Then she showed me the photo, and I said I thought it looked more like a bedbug than a tick. At this point we both freaked the fuck out. We inspected the clothes (2 items) inside and out and didn't find any other bugs, eggs, droppings, or evidence of anything. But I have an INSANE bedbug phobia so we still immediately threw everything in the package, all the clothes we were both wearing, and all bedding/blankets near the couch into a maximum heat hour long wash/dry cycle, threw the packaging away in a tied-shut trash bag in the outside trash can, and then obsessively vacuumed the whole living room. The carpet, every path we walked along during cleanup ie the way to the laundry room, every surface of the couch, under all the cushions, in all the crevices, and underneath the couch as best we could manage. Then I immediately showered. Fiancee emptied the vacuum into a sealed trash bag and threw it away outside.
I'm currently sleeping on that couch (long story), so I slept there again last night and didn't notice any bites when I woke up. I have very sensitive skin and am allergic to everything under the sun so I feel like I'd react if I got bit.
My question is: does this look like a bedbug, or is it a tick or a swallow bug instead? Our mailbox is on our front porch, and there is a bird nest on our front porch about six feet away from the mailbox so that's why I mention swallow bugs. We haven't traveled anywhere recently, or had people over really, or brought any new items into the house. No used furniture, no thrift store clothes, etc. And I've been sleeping on this couch for months and never been bit or seen a bug, and this one showed up at the unboxing location 10mins after the fact so that's why I'm pretty sure it came from the package.
Whatever it is, odds of it coming into our house via a package? If so, odds that it's a lone hitchhiker or that there were more? And if it is a bedbug did I do the right things to try and protect our home right away, or is there more I need to do? Are we just fucked now? I'm scared shitless of these things and I have OCD so I never know if I'm reacting appropriately. We do have variegated carpet beetles by that couch, but this doesn't look like that to me. Please help!
