I'm not talking about the bit left over at the end of the doobie/spliff/etc, but the 6 legged beasties with the indestructable carapace and the "fuck you" look on their little insectoid faces. I'm not sure how that is possible, but its true. Try looking one in the eye one day.
The issue is that some genius of modern architecture put this flat's water heater inside one of the kitchen cupboards. Of course, creating and ideal warm dark roach habitat. A little like those preferred by fleas.
A week ago my little sister came to here to stay, and I didn't want her thinking that your Aunty B could not manage the number of species living in the flat. So before her visit, I set those you beaut bombs off, one right in front of the open cupboard which had become Roach Dorado.
Effects: Sticky floor, and many roach cadavers in a localised "zone of impact". Sucessful strike to by Aunty B - huzzah! Unintended side-effect: A whole army of teeny tiny roach scouts looking for somewhere new to set up a homestead and make babies at the rate of approximately 1,287 per 24 hours. Places I have since found roach re-con include: crawling across my keyboard; inside one of my transparent plastic document sleeves for a client meeting; on the stove; on the bathroom cabinet; on the kitchen splash back. They are possibly some level of instar, to dredge up a bit of entomology for you, dear readers, and are only about 5-10 mm antenna to rear. Not too threatening now, but they will be in a couple of growth cycles.
The effect is kind of like that of the Iraq war on global terrorism, in a way.
