take that, puny insects

We have (well, had) a problem with ants trooping through the skylight in the master bathroom at our new place and tromping all over the countertop. Sunday, I bought a bag of diatomaceous earth (which is composed of the fossilized remains of the microscopic buggers you see in the picture) and dusted the countertop with some yesterday, just to see how well it works.

There is now a desiccated ant graveyard surrounding the sink, and no ants crawling through the skylight. This shit be awesome.
