There was a bit of a scene in my house last week. Let me set
the stage for you.
I’ve had a very long day. Up at 4:30 AM, done with work at
8:00 PM. I’m exhausted and finishing my lentil quinoa bowl from Panera. All I
can think about is taking a quick shower and lying down to go to sleep.
So I go into my bathroom, turn on the shower, strip my
clothes, and start fishing out bobby pins from my hair. And then I see it.
Within about half a second, I’m out of the bathroom and
hiding behind my doorframe, screaming, peering back into the bathroom at a huge
cockroach perched on my shower curtain.
Now before you assume that I’m a sissy girl who hates bugs,
let me clarify that I regularly scoop up spiders, crickets, and other arthropod
friends and take them outside to set them free. But when it comes to
cockroaches, I simply cannot. I JUST CAN’T.
They’re big, so they feel very invasive. They scurry. They
climb up walls. They twitch their long creepy antennas. They’re dirty. They
make sounds when they walk. Their presence in my personal space disturbs me to
my very core- even more than people who hashtag their babies. And that’s a lot.
The only roach I will ever be REMOTELY okay with, Hal from Wall-E. |
After screaming a bad word at the roach for a while, I left
the room to collect myself. Was I being unreasonable? Well, clearly, yes. But
was I being cruel in my wanting to kill this cockroach? Should I try to capture
it and take it outside like I do my arachnid friends? Was he just as scared of
me as I was of him?
A recent paper claimed to prove that roaches have
personalities. Basically, they microchipped the little bastards and dropped a
bunch of them into a brightly lit arena with shelters here and there. Roaches
are naturally averse to light, and will seek dark places to dwell. The folks
running this study used the microchips to track the movements of these roaches,
and found that some lingered in the light longer than others, suggesting that
they are “braver” than those that sought darkness immediately, who were
interpreted as being “more timid.”
Another interpretation, or perhaps just a more continued
explanation, of these results is that these foraging/shelter-seeking behaviors
have evolved to be varied in the species because it is advantageous. Since
roaches are social and live in colonies, it would make sense for these behaviors
to be varied. Perhaps the roaches who ran for darkness first were trying to
signal to the others what to do. Or perhaps the ones who explored in the light
were more likely to find an escape from the arena altogether, or even a new
food source for everyone.
I touched on the evolution of personalities in my post
Myer-Briggs Voodoo Magic. I don’t think it’s too much of a jump to say that
social animals that live in groups have mostly evolved to have a variety of
exploration behaviors, simply because it improves survival chances of the
group.
Am I prepared to say that cockroaches have personalities? Oh
hell no. But then again, what exactly is a personality? Maybe, by classical
definition, cockroaches do have personalities. Are they as complex as ours? Or
as dogs? Absolutely not.
It begs an interesting question- where do we draw the line
on which animals think and feel, and those we deem as unthinking and unfeeling?
Would you easily kill a dog? No. But would you easily kill a lizard, or a
starfish, or a shrimp, or a ladybug?
As an interesting side note, I read some research recently
on invertebrate pain. Evidence suggests that insects do not feel it, but
crustaceans like crabs most certainly do, and even seem to remember and fear
the cause of that pain. Does that change how you feel about killing arthropods?
As for my roommate, I did not kill him. But it wasn’t for
lack of trying. I swatted at him with a shoe, screamed, and ran. Then he
climbed onto the ceiling. So then I went and sat on my couch and cried for five
minutes, until I gathered the courage to spray him with Lysol until he scurried
behind the toilet. After that, I shut the bathroom door and crawled into fetal
position in my bed and tried to manage my roach anxiety. I had roach nightmares
all night.
I spent this past Sunday spraying my house with bug spray
and sanitizing every single surface I could find. And now I have a can of Raid
in every single room, ready to bring death to any of the “brave” roaches that
dare show their ugly little faces in my house.
