Hello, and welcome to our forum. That’s definitely an adult bed bug’s shell, so you’ll want to start a full treatment right away. Here is a link to our recommended treatment solution: http://www.bedbugsupply.com/how-to-get-rid-of-bed-bugs-in-4-steps.html
Ok, thank you! We actually had a massive treatment in our previous apartment and now moved to a new one. I am just trying to figure out, if that one can be a dead one(it has legs) or a shell that would mean that we have those bugs in our new apartment too. It is possible that dead bugs came with our clothes when we moved.
Thank you for your kind help!
