ELI5: How are roaches completely unaffected by mircowaves?

Alright, so we've got a *tiny* roach infestation right now, and they like to scurry around anyplace dark and cramped, like our microwave oven. Even when it's running.

I know that microwaves work by vibrating the particles of whatever's in them to create heat with friction, but why doesn't that work on roaches? I mean isn't fire super-effective against bug?

Someone mentioned this in a post not too long ago. Basically this guy was cooking food and noticed a cockroach running around in the microwave. Freaking disgusting but anyway. 
The microwave doesn't heat food evenly. That's part of the reason for the rotating platter. The roach senses this and runs to areas of little to no radiation.
