Dead bed bug + ?

5686.   hello my name is Line these are the pest that are in my apartment. I live in Niagara falls Ontario and the weather is just starting to get warm. The pest are very small not sure the size as some are a little bigger then others , also have wings.They do bite as I am covered in bite marks and have a very itchy and burning feeling. Once bitten they are small and then start to swell up if scratch causing irritation to the skin. 

You may have two different pests. The image you provided looks like the remains of a dead bed bug, which would explain the itchy bites. However, these insects do not have wings. Ed Saugstad, retired entomologist; Sinks Grove, WV.
