Should I Kill a Black Widow Spider?

“We don’t eat animals,” my 3-year-old told our new neighbor proudly before her smile turned to deep seriousness, “but, my papa kills black weirdos ’cause they will hurt me.”

“Widows,” I said quickly. “He kills black widows. Well, he used to.”

Despite warnings from friends, family, strangers, the postman and all the kids at my daughter’s most recent birthday party that spiders, especially black widows, are intent on murdering my children, I’ve finally convinced my husband to stop killing the black widow spiders he finds around our yard.

He’s come a long way. Almost vegan five years into our marriage, he grew up on the Atlantic coast of Spain boiling lobsters alive, enjoying Spain’s most famous delicacy, jamon serrano, almost every day and running with the bulls without a second thought until our first date.

Today you can find him building a luxury suite for the injured moth we’ve taken under our wing, or capturing and re-homing rouge spiders scurrying across the floor attempting to escape our cats’ merciless appetite for fun.

It’s obvious he’s embraced the world I’ve been immersed in since childhood with open arms. While I’m not arguing that it couldn’t fit the definition of insanity, I remember my mom spending the few hours she had between jobs dutifully scooping up seemingly endless parades of ants from our sink and depositing them oh-so gently outside before starting on the dishes. I knew to expect to be late anytime we had to pass a swimming pool as the desperate struggling from the thirsty insects who were unlucky enough to fall in could not be ignored.

I was usually happy to help, except when it came to the spiders. I didn’t want them to die, but I couldn’t bring myself to even look straight at the really creepy hairy ones. She’d often remind me that my screams at the sight of a spider were like a dinosaur running away terrified of a mouse. Logic aside, I still let her take care of capturing any stray arachnids and depositing them outside.

But black widows are a different story, especially since I have three young children intent on crawling through every crevice of our yard. Even someone as infatuated with preserving life as my mom insists we kill them.

As scary as the infamous black spiders with the red hour glass marking are to me, these arguments reminded me of so many I’ve heard before in defense of killing creatures that share space with humans. The recent tragic killing of the terrified mountain lion who inadvertently made its way into the urban jungle of Santa Monica was defended by the logic that there was a preschool across the street from where the animal was hiding.

We have to kill raccoons because the roundworm found in their feces could kill our kids. I’ve seen raccoons skulking around in the shadows of the night my whole life and I haven’t lost a friend to the worm yet. In fact, only five deaths have been recorded since 1981 in all of the United States.

The cars that speed by my house on any given morning pose more of a threat to my kids than any creature in my yard, but exterminating that hazard would probably be frowned upon.

So how did I get a once-live-lobster-boiling Spaniard to stop killing what everyone assures us are certain child-killers?

Well, we conducted an unscientific experiment. In prime black widow territory, we removed all the black widows from the area and waited to see if my theory was correct. In less than a week, the three-foot length of wood fence had once again become prime black widow locale.

Removing (or killing) one spider just opened up the space for a new one to take its place – the definition of senseless killing.

A little research proved that spiders play an important role in controlling pest insects, like mosquitoes and flies, and even eat other spiders. Spiders might leave a nasty bite if they feel threatened, but we are actually prey to mosquitoes who carry a whole host of infectious diseases to us and our pets.

And for any bird people out there, they are a favorite meal to many species of birds.

My grandpa dismissed my experiment with one word – pesticides. And it’s true, you won’t find an insect in his yard.

But as insane as it may sound in this world where we turn to chemicals as a quick fix for any problem, I’ll take my chances with the bugs. We’ve survived them for hundreds of thousands of years, the jury’s still out on how we’ll fare in an environment saturated with chemicals.

**Note: Obviously if black widows are setting up their homes right where your children play, like on their play equipment, it is a good idea to remove them relocate them in a less-trafficked area.

  1. Hi Tina

    To me, your argument seems kind of off… Yes, black widows are great at killing bugs and other insects – but so do other spiders! Why do we need to keep around an insect that could easily kill us when the garden variety does the job just as well? What possible advantage could having black widows have that surpasses their threat level? It just seems to be asking for trouble…

    • Well, actually they can’t “easily kill us..” . I’ve been bitten by a widow 3 times and, while unpleasant…well, actually quite painful for a few days, the bites didn’t amount to much. Can they be dangerous to some people? For sure, especially the elderly and very young, but treatment, if sought, is always effective and will prevent severe symptoms. I no longer kill them. As Tina noted, if you do kill one, another, or more will be back within the week. In fact I now have one in the service restroom at our building that I leave alone. She’s about an inch long at the legs and has trapped and killed roaches much larger than her. She doesn’t bother me. and I don’t bother her. I’m not a Vegan either, “Vegan” is an old Navajo Indian word that means “Bad hunter”. Thanks for the posting Tina!

  2. Hi Tina.

    I was happy to read your story. It is nice to know that I’m not the only one who isn’t killing black widow spiders willy nilly. We get quite a few of them in our yard too. Every once in awhile, I find one in our tool shed or in our ‘rec room’. I’ve never found one in our house. When I see one (or more) I have special jars for capturing them. I relocate them to a nice place elsewhere to live and release them. I have a few good sites that I believe are better habitats for them away from human habitation.
    Like your grandfather, my father is also a spider killer. He hates spiders and kills them all. Interestingly, he is always getting bit by spiders (including black widows). I never kill spiders and have only gotten a spider bite on rare occasions when I accidentally stuck my hand somewhere without wearing gloves. Maybe it’s my good spider karma! I highly advocate wearing garden gloves and just being aware and paying attention. Black widows are not killers, they do have a venomous bite, but it isn’t as deadly as people believe it to be.

  3. Thank you Tina for defending spiders. Finally a woman that doesn’t want to burn down her house because of a spider. Black widows are beautiful creatures that aren’t aggressive towards humans and serve a vital role in our yard health.

  4. Hi author, seems you have not first handed seen the arachniphobio that these monsters inflict into the consciousness when seen, It’s more psychological than oh , i dare u to have this spider bite you. You didn’t see any, just webs. Because it was daytime. I am the opposite, I am active at night, and these things are terrorizing. cut.

    -California is nice and blossoms like all else in spring time lifes abundant critters are renewed. Only then does the clock start and it stops at frost, or winter. )thank god( .At night I wander through our garage and open a door, following the cement path, eyes ablaze, I see a thread of silk, Eye’s close in and spot it, would of caught me on the right leg had i stepped again, webbing over clothes, doesnt come off ez, freaking out (what was that!). ewww effect, calming down I loook myself over for a spider (results may vary) this would be the result of me taking another step. I sidestep the web and walk 10 paces, web another web web web, spider, spider, Big one, up there! huge ass one. thats it, it sucks! The insect flyers that follow light bump me at night , Triggers (arachphobia) , hair blown by wind (trigger). ant crawling on me? trigger!, an hour later In dysunction like an alcoholic bcause of the phobia,I put down door on my worktable and within 30 minutes it had a web and spider on it.This was it! I break the rules, I use
    ….. Flame ….
    Natures dissolvent of literally everything. Oooh, after every pop (kill) , I felt the phobia trigger, but lessend by every target gone. Flame does it all, webs, spiders- instantly– cracks, holes, go hide I giggle as the flame thrusts into the crack, hold for half second, dont burn anything, in 15 minutes I had erased all the webbing and spiders in the area,
    I reccomend this for everyone, but I also know this isnt true that All people know fire like I do, So I choose fire because I literally work with it daily, I know its blues,reds and yellow aura like a thermometer. this is why its not recommended to everyone. schools teach nothing about fire (what a shame)
    I plan on spraying today to keep em from coming back. This is only for the Blwido. I love animals and leave em alone, but the blwidow just gets so arrogant !!!
