I remember the holes opened up in a weirdly regular grid pattern...not hexagonal, but more like a distorted rectangular grid. I'm going nuts with the spray-shellac, dousing all these ants. Ants are among the very few insects I will kill on site but even then it makes me feel a bit sick inside, and so in this dream I was feeling pretty bad about what I was doing even though I was still compelled to do it.
Finally I spray a last hole but the insects coming out, though slowed by their lacquer bath, somehow don't stop, and suddenly I see (a la dream logic) that they're not ants but bees or wasps.
