Squashing bugs for no reason is wrong I think, but we all have different lines that we draw when deciding on what is a valid reason.
If we’re really honest with ourselves, we could safely and peacefully share our homes with most common household pests. Some household pests eat other household pests, so it may be best to just maintain the balance.
Still, it seems the cultural norm that extermination of household pests is o.k. because not wanting bugs in your home counts as a reason for killing them. You’re not killing them for no reason, you have a reason: you don’t want bugs in your house.
Someone may actually choose not to do home extermination because they’re fine with seeing a few bugs around their home but- realizing that many other people are not o.k. with seeing bugs- they may follow up with extermination at their place of business. If you’ve never seen the extremes in people’s reactions to seeing a bug at a hotel or restaurant, trust me: not wanting to hear people freak out and yell at you can seem like a pretty good reason to kill some bugs.
Other people see a bug, then fear if they turn their attention away from it that it might crawl on them. Eeew! It might crawl on me! A bug! Crawling on me! So, they kill it but they don’t kill it for no reason, they have a reason: they’re scared it may crawl on them.
Other people just have it deeply ingrained in them that bugs are bad and/or gross. Not much thought goes through their head when they step on a bug, it’s just their natural impulse. They don’t sadistically find joy in it, they’re just programmed to step on bugs. These people aren’t killing for no reason, their reason is “bugs are to be stepped on.”
I think at the very least those of us who feel programmed that “bugs are to be stepped on” should work to overcome that. The irrational fear that “it might crawl on me” is another reaction that I thing we ought to try to overcome.
I work in the service industry and, sorry, I’m going to keep killing bugs at work. There are just too many people who freak out over such things. Maybe not fair to the bugs, but I can’t bring myself to care. I’d rather make it through my 8 hours at work without people flipping out at me. Of course, this goes both ways: I once caught a mouse at work, I covered it and crushed it (very quick death)- I knew full well that there was an equal chance that someone would deem me a monster for killing a harmless little mouse. The service industry very often puts you in lose/lose situations.
At home, I’ve never bothered too much with pests. I’ve always been in apartments, and most of the landlords I’ve had have been a hassle to deal with anyway so it’s just a headache to get it taken care of.
We had termites that had to be dealt with a few years ago- my landlord didn’t want his building eaten away. Currently, we are beginning to suspect that the one mouse we’ve been seeing over the past month might actually be several mice. Mice leave bigger poops than silverfish, and they also eat through food packaging. So, we may decide that we have a “reason” to kill the mice. We’re not thrilled about it though.
