Living in Texas, I can affirm that ants can get anywhere. Anywhere whatsoever. The inside of bird-feeders - via the sticky liquid - into electronics, and of course in your pants.
These guys here cause subsidence, so a mere disc-drive would be an easy target.
Take a lesson from Richard Feynman. Observe them, and tempt them onto a different path. Use sugar, or a proprietary...erm, little plastic thing with nasty stuff in it. Wait until the dead of night, and if you can't wait for their slow demise, have a mallet at hand.
I spend a huge amount of time trying to save creatures...even cockroaches get put out carefully, but ants have made me their enemy.
