Hix hix, my computer has encountered a dangerous situation! When taking my computer out of the bag, I saw some ants creeping near my laptop, two ants were on the laptop! I was wondering that they could have crept into my laptop throught vent hole

! If that happened, it was really dramatical for my laptop!
How to know is there any ant creeping inside my laptop? And if they were inside, what can they make harm to my laptop? And how to dismiss the DAMN ants, is there any solution for that? Please help me!

Thanks in advance!
P/S: I really keep my laptop clean so that there's not any piece of food or anything like that in/on my laptop! So the ants have no reason to come inside!
