Mites in my Nitro 5, AN 515-54

For a while, I've been seeing these small white insects, which were coming out of my hinge. Didn't pay much attention to it, but then I saw a few coming from the gaps on my charger brick. Did some research and found out that these might be dust mites. Can anyone confirm the same and suggest some solutions to get rid of these insects. I had kept my laptop within an airtight plastic bag along with naphthalene balls for an entire week, didn't work and still found these afterwards. Also have kept the laptop under the sun to make it uncomfortable for these insects, still no results. I had opened my laptop and to an extent tried to clean the insides as well. I didn't find any insects on the motherboard or underneath the hinge but even after the cleaning, I get to see one or two every other day, it might be hiding somewhere secluded. I hope these would be identified with the picture given, my phone's camera is not the best, these insects are extremely tiny too. Any suggestion would be appreciated. Thanks.
