I got to thinking about cockroaches the other day, probably because the news mentioned that some of Vancouver’s apartment buildings are becoming infested with bed bugs. No matter how you cut it, bugs are just creepy. They make our skin crawl, sometimes literally. They’re the most alien of the animal kingdom (besides bacteria, whatever the heck they are) that we can see. And theories are that should there be a nuclear holocaust it’s the insects that would survive. In fact, comparing populations, there are 12 times more insects in the world than the total of human beings (and we’re at 6 billion). It’s a sobering thought and a good thing that most of them are small.
Most places have cockroaches but unless you’re living in a dirty building or particularly slovenly, you may never see them. I’ve never seen a cockroach in Vancouver and only saw a small thumb-sized one in Seattle once. They prefer warm and dark places, with fecund garbage. In colder climes, that means moving indoors where you and I might be.
They leave scents in their feces and pheromone trails so that their buddies can find them. Once you have one, you’re likely to have a whole gang. Cleanliness, wiping up food spills, vacuuming are ways to stop cockroaches from moving in but once they’re in, they’re extremely difficult to eradicate.
The buggers are tough. Supposedly a decapitated cockroach can survive for several weeks before dying of dehydration or starvation. I take it that’s the body and not the head. They live about a year and can produce 300-400 offspring or more. Some species only need to be fertilized once to produce for the rest of their lifetimes. They’re so hardy that they can take 6-15 times the radiation of a human but would possibly still not survive nuclear war, though they’d fare better than fleshy humans.
They can live a month or so without water, longer without food, be deprived of air, frozen or immersed in water and can recover. They aren’t slimy but like many insects we don’t enjoy touching them. And they are just very alien looking. Hence all the horror and SF movies with buggy creatures. Many humans have a natural revulsion. Cockroaches do have a couple of natural enemies; other insects. Certain wasps and centipedes will attack them but if you were trying to get rid of them, you would then just have a new pest to deal with.
I have really only encountered the creepy crawlies twice. Once was in Mexico, in Taxco. I was on an open restaurant veranda, having a drink with someone. A cat was wandering amongst the patrons. Thinking it was the cat rubbing against my leg, I ignored the light touch, but when I looked down there was a cockroach on my leg. I jumped up and stomped so that it dropped. The waiter and my friend both stomped on the three-inch long cucaracha and it just kept running, right over the balcony.
Later I was in Cuernavaca. The adjoining bathroom to my room had two cockroaches hanging out on the ceiling. I was freaked out by this and tried to close the door, though it wouldn’t shut completely. They never moved but I kept a wary eye on them.
The other time was in Calcutta. Every hotel I tried was full and I was looking at worse and worse accommodations to stay in. Finally I found a place. It was rife with cockroaches so I slept with the lights on to keep them at bay. It also had fleas (or maybe bed bugs) and I slept in my own sleeping bag though it was hot and humid, to save my flesh. (I also got dysentery from that place.) They weren’t as big as the Mexican cockroach had been but they were more prevalent.
Thankfully, I’ve had no more experiences with cockroaches. I share that human abhorrence of things many legged. I don’t mind spiders now, even though I was once phobic (See: Spider, Spider, Burning Bright.) Sometimes it’s fascinating to watch how an insect works, but at a distance, not up close and personal and in your home.
