Idk.. there's about 150,000 ants per pound. Let's call it 200 pounds of ants, so 30,000,000 ants attacking you all at once?

Even with an incredibly efficient stomping methodology, you'd let some through, which would start crawling on and in you rather quickly.

After a few thousand ants (a fraction of a fraction of the total mind you) get inside your ears, nose, butthole and urethra, biting, chewing and slicing one micro-cut at a time, I'm fairly sure you're out of commission, going stark mad and opening the way for the remaining millions of ants to quite systematically kill you and methodically cut you in small carryable pieces to bring back to the nest.

But hey, hopefully shoes and soap will help ;)
