If they're sealed in a plastic bag im guessing they'll die. Try using a can of compressed air to get them out?

haha Rachael you are so cute

Drown the little bastards. Put the laptop in a bath.. Oh wait.

Omg I don't blame you! This type of thing would absolutely and completely creep me out/ make me feel sick also! But yeh seal em up airtight and wait for them to die... if you get adventurous you could remove the keys and get em out that way. Maybe open the hardware covers on the bottom and see if they're right through.

Lulz, my friend spilled a bit of wine cooler on her laptop keyboard (not enough to damage it) but some sugary residue was left over even after she cleaned it. Next day, ants were crawling in and out of the side vent and SD card slot. :o

And not surprisingly, it overheated a few days later, and they died a fiery death
