Dead bug inside MacBook Pro Screen

Last night I noticed that a small black bug (maybe a thunder bug?) has somehow crawled inside my 2017 13" MacBook Pro screen (which according to Apple's design is sealed and therefore this should be impossible) and gotten squished. This is very irritating and I was wondering if anyone from Apple could advise me on what to do. If nothing can be done at home, it's not in warranty as a 2018 purchase but surely this is a design flaw?
