Who's the toughest?

Some accidental experimentation has led me to the following observation: Black ants can stand at least 3 minutes minutes on high in a strong microwave oven.

Out of something in the neighborhood of 12 ants that came in on a kid’s bowl, not one dead ant was found after a 3 minute run in the microwave.

If ants could survive that long, I wonder how long the roach, as most likely to survive a nuclear holocaust, would last? Unfortunately my wife frowns on roaches in the kitchen.
