small bug-insect inside display MacBook Pro (Retina, 13-inch, Early 2015)

Last week a small bug was crawling across the dock it has stopped at this location and by now I would assume it has died behind the display the bug also looks to be breaking into pieces and making a larger mess, I don't have apple care and my Apple 1 year limited warranty is no more. My questions would be how this even happened and price range on removing this bug or should I just go to an Apple Store?
