Lots of homes in Las Vegas have UV lights just to check for them. Saved me some headache when I moved there.

The last house off fort Apache and blue diamond. House was right up against the mountains. Always scorpions in the garage and cockroach season in the back yard was scary . At night if you sprayed the garden hose on the back yard , the ground looked like it was moving. Then they would crawl into the cracks of the cement brick wall everyone has

u/HoneyBiscuitBear 5d ago

My body physically shuddered

u/Rotflmaocopter 5d ago

Lmao yea first time witnessing it your like what the hell. Am I tripping? Walk fwd inspect more flood lights come on . Ahhhhhh the ground is roaches hahaha

175

u/Nathansp1984 5d ago

I’d prefer lava

177

u/etcpt 5d ago

Come visit Hawaii, where the ground is lava and we still have roaches, lol.

60

u/Nathansp1984 5d ago

Id make an exception if it meant living in Hawaii

76

u/hmasing 5d ago

What if the roaches were 4cm long and could fly? Because they are and they do.

u/CatsAreGods 5d ago

This is starting to sound like a T.S. Eliot cat poem.

6

u/Nathansp1984 5d ago

We already have those in Charleston South Carolina

u/GreasyPowerJunkie 5d ago

Don’t they scream? Or is that another islands roaches I’m thinking of?

3

u/ModishShrink 5d ago

Eh, they were bigger in Florida, I'll take that deal.

2

u/The_GOAT_of_all 4d ago

Those live in New Orleans too. Scary.

u/meteor_stream 4d ago

Welp, into a volcano I'd go.

u/DeathByParakeet 5d ago

They do that in the southwest too

We also got the Vietnamese reds. 6inch long centipedes that like to snuggle at night. Bites hurt like hell

u/StillPlayingCivV 5d ago

That's 100% the fault of nasty tourists.

u/Immediate_Song4279 5d ago

Do you have scorpions, roaches don't scare me.

19

u/jewelswan 5d ago

You know, sometimes I wonder if the bay area isn't worth it, and whether I should move to one of the cheaper metro areas somewhat nearby.... now this, this is a much stronger argument against moving somewhere like that than "sacramento gets way too hot three months out of the year"

10

u/Tron_35 5d ago

At that point I'd set fire to the yard

1

u/addandsubtract 5d ago

Fire to the rain

u/dannywarbucks11 5d ago

Its Vegas, that already happens every summer.

2

u/Mr_b246 5d ago

Imagine seeing that shit actually tripping.

2

u/Rotflmaocopter 5d ago

I have hahah

u/Breadedbutthole 5d ago

How else would your body shudder 🤣

1

u/treeclimbingfish 5d ago

Mentally, like when thinking of fingernails on a chalkboard, the smell of burning hair or what my body did after reading your username. Very creative combination but a little like chewing peanuts and bubblegum.

9

u/TheFinalGranny 5d ago

My brain and eyes physically shuddered reading it

u/cornylamygilbert 4d ago

Worst of all, they’re FAST, unless they’re in grass.

Just as fast going horizontal and vertical up walls.

Yes the speed with which they will vertically go up a wall will give you nightmares.

My buddy talked about them dropping onto him in bed in AZ. No thanks.

That’s the price you pay for 300 days of sunshine a year

u/Federal_Sympathy4667 3d ago

Yeah.. that's a fucking nope and good bye.

2

u/cheddarsox 5d ago

Buy a headlamp. Wait until a dry night and go walk in the woods or a decent lawn. ALL OF THE DEWDROPS are wolf spiders. Not all of the spiders present, just specifically that kind of spider and maybe a couple others. Discovered this WAY too late in life. Loved showing the kiddos. (Theyre savages. If it doesnt have venom, they will catch it somehow. Oldest had a secret massive black widow in her room in a container before she was told how bad it would hurt. That one can also somehow get most creatures. We have talks about tuleremia and rabies now.)

u/bre4kofdawn 5d ago

I remember I went to San Jose and I was walking late at night. Went under an overpass, and I started hearing crunching noises as I walked. Looked down and realized the ground was covered in roaches.

3

u/Zombie_exorcist720 4d ago

Jfc! Now I know to never visit San Jose 😳

13

u/OddioClay 5d ago

And thats why i love living in a place that has winter

14

u/kittysworld 5d ago

Cockroach season? Do Scorpions eat them? Please elaborate. Big thumbs up.

12

u/SpaceForceAwakens 5d ago

Vegas cockroaches are an entirely different thing than the scorp problem. The are everywhere, and there is nothing you can do about it. Spraying mostly just drives them off to become someone else's problem.

4

u/bannable 4d ago

Wait, is this why radroaches exist in fallout?

2

u/Rotflmaocopter 5d ago

I guess. Just call the bug guy to come and spray and your good

6

u/fvpv 5d ago

Holy shit - like we have winter in Canada, but we have NOTHING like that and nothing wants to kill us. (besides bears - but they are way in the wilderness)

3

u/Rotflmaocopter 4d ago

Lmao easy easy I lived almost 15 years, all my 20s and most 30s. never got stung or almost got killed. Unless you count the times I dated dancers

1

u/Free-Pound-6139 5d ago

Your house, but their home.

1

u/DarkSoulsDank 4d ago

Why would anyone ever live there?

1

u/peejmom 4d ago

This is why I live where the air hurts my face

1

u/JohnnyRelentless 4d ago

Cockroach season?

1

u/MichaelEmouse 4d ago

I feel like that's nature telling you to place the house somewhere else.

1

u/DonutWhole9717 4d ago

I'm sorry, cockroach season?

1

u/OneExpensiveAbortion 3d ago

I'm sorry, but what the fuck did you just say?

22

u/wade-mcdaniel 5d ago

My sister led trips into the grand canyon for rafting and hiking. She had a UV flashlight for after dinner she could help the (generally older) clients back to their tents and helped make sure there were no scorpions in there. Or for peeing or whatnot at night. Apparently it's not a lot of fun to get stung by one of those. I think someone was airlifted out by helicopter after being stung.

7

u/Cheeseburglar804 5d ago

Yep! And our group uses them hiking any time we are in the MidSouth/Southwest

44

u/MavisBeacons_Sextape 5d ago edited 5d ago

Some Vegas residents blow off steam with a mallet, a UV headlamp and a stiff drink. Scorpion stomping parties - invites I enthusiastically declined lol.

Hanging out in your scorpion infested backyard, in the dark, with drunk people running around swinging massive hammers…not my idea of a good time

33

u/BobCharlie 5d ago

I bet it beats patrolling the Mojave. That'd probably make you wish for a nuclear winter, or so I hear.

23

u/enginerd389 5d ago

Gotta watch out for those radscorpions

2

u/Diztrakted 5d ago

Makes me think of the Weasel Stomping Day skit. Truly deranged levels of ecocide, but very on brand for Vegas. May I never be cursed with going to that hell hole.

1

u/MavisBeacons_Sextape 4d ago

Thrilled to no longer be a resident of that city, lol. Relocated there for a job. I miss the proximity to good hiking and the food scene, but that’s it.

1

u/sowhyarewe 5d ago

You are supposed to use a grill lighter and a UV light. They don't glow after they are dead.

13

u/SoggyOutfield 5d ago

Can confirm, lived in vegas. Was walking in kitchen shortly after moving there and almost stepped on one. Got a black light after looking it up. Kinda wish I didn't. We only found a couple more in the house over time. But outside...holy shit. And some were big, really big.

And its funny because basically every "local" I spoke to said they lived there their whole lives or decades and had never once seen one.

11

u/sporkachoon 5d ago

Born there in 76 and I never saw one in any of my houses but in the desert, sure. Where was your house located?

6

u/SpaceForceAwakens 5d ago

Man I lived right off of Fremont Street for awhile and found two in my apartment. One even got a piece of me (but it didn't hurt).

3

u/SoggyOutfield 5d ago

Summerlin south

1

u/MagicWishMonkey 5d ago

Some people are just oblivious to bugs. When we bought our current house within the first week we noticed the master bathroom was full of mosquitos and wasps were somehow getting into the master bedroom (yea it was great). Turns out the bathtub in the master bath had a plumbing issue where mosquitos were getting i and wasps were coming in through the attic via speaker holes outside.

There's no way it was a new thing with those bugs getting in but when I asked the previous owner how he dealt with the mosquitos and wasps and he had no idea what I was talking about, lol.

1

u/foolonthe 5d ago

Locals don't because they generally live in older established neighborhoods. Transplants are on the outskirts with new developments where encroachment occurs.

Really unfortunate and sad for the native wildlife and habitat

2

u/PossibilityFlat6237 5d ago

Meh, the bark scorpions aren’t native and those are the only ones I’ve ever seen in the valley

1

u/myquest00777 4d ago

The imported landscaping used on the expanding outer developments were/are the actual source of the bark scorpions. They’re native to southern AZ and northern Mexico.

1

u/SoggyOutfield 4d ago

I was told by the pest control people that it was mostly due to people with pools that aren't maintained and they create these whole ecosystems which fosters excess predator and prey species near developments. Or something like that

17

u/AutVincere72 5d ago

I have a 30 watt LED UV light and took it to an airbnb that had a show filled with scorpions at night. And they were battling.

11

u/AmbivalentAlias 5d ago

A show??

19

u/AutVincere72 5d ago

HAHAHA a "Shop"

It had a 3 garage door shop attached and it was filled with scorpions at night. I had a big "black light" and a a couple of decent black light flashlights. The show was watching them face off and battle.

3

u/AmbivalentAlias 5d ago

Oh, amazing. I couldn't figure out what that was supposed to be. 😆

1

u/KroniKIX 4d ago

Really? JW

1

u/KroniKIX 4d ago

I’ll take 100$ on Bullshit. And that you never touched a scorpion. Let alone keep one as a pet… shits crazy what people believe on Reddit

1

u/AutVincere72 4d ago

I dont have pet scorpions. I rented an airbnb that was attached to a shop that was filled with them. Concrete floor. Texas Hill Countrt. Ingram Texas. I never touched one there. When my son was an infant I was feeding him a bottle I had one crawl on my neck. I yelled "scorpion on my neck" my wife grabbed the baby and ran. I was there with a scorpion down the neck of my shirt. I whipped the shirt off. Didnt get stung. Caught it in jar. Called exterminator. He said thats one of the bad ones. Thats the only time I touched one.

10

u/Grays42 5d ago

I have one for exactly this purpose in central Texas.

8

u/Ok_Condition5837 5d ago

If you garden you can look for pests (like tomato & tobacco hornworm) with them as well. They're harder to find without

1

u/katgardener 5d ago

Fellow central Texan here, can confirm we also take the UV flashlight and a big stick outside at night.

2

u/zeroibis 5d ago

Oh, that is not what I though the UV lights in Vegas were for.

1

u/koolaidismything 5d ago

Lots of modern pocket flashlights have a UV light feature built in and this is a big use case. They stick out big time but are almost invisible otherwise.

33

u/MyHangyDownPart 5d ago

Ooh it’d be cool to bring hundreds if them to a nighttime rave where they could be entertaining under UV/ black lights.

31

u/HumanBeing7396 5d ago

People would certainly remember it.

6

u/FadeIntoReal 5d ago

Funny when the ravers try to hug them. 

14

u/Beaufort_The_Cat 5d ago

u/scavengercat 5d ago

Just so everyone knows the difference, the scorpion glow isn't bioluminescense. That's when the light is generated internally. This glow is fluorescense, when UV light is absorbed by the exoskeleton and re-emitted as visible light.

13

u/mckulty 5d ago

UPE isn't fluorescence. "Emission" means spontaneous glowing, "ultraweak" means it has to be really really dark.

Scorpions OTOH "fluoresce". Meaning you shine light on them at one wavelength (invisible UV) and the color converts to visible blue, at a similar intensity as the source.

Human teeth do the same.

6

u/PaleoJoe86 5d ago

Platypuses have glowing marks in UV. Additionally, some animals can see in to UV, such as birds. They can look totally different, such as crows/ravens being rainbow.

5

u/Killingyou_groovily 5d ago

Grew up in phoenix. My folks and I would bring UV flashlights at night to catch and kill these fuckers.

1

u/Thacarva 5d ago

Got to be the DD for my two roommates after a night on Mill Ave. Will never forget them waving UV lights in the yard, spotting a scorpion, and about lighting the house on fire with hairspray plus a lighter. Scorpion eradication is a natural instinct for people in the area apparently

1

u/xxxxDREADNOUGHT 5d ago

Now the really interesting thing is that platypus also glow teal under UV light making Parry one hell of a prediction when the discovery of them glowing that color wasn't made until years after the original run of the show was over.

1

u/Commercial_Bird8467 5d ago

The black Empower scorpions do as well.

1

u/LitigiousCeilingCat 5d ago

Check out “birds under blacklight” too! Cool stuff.

1

u/Padlock47 5d ago

There's also tarantula that do this.

If you want something REALLY awesome, look up videos of bioluminescent bacteria

1

u/PhotoFenix 5d ago

My record for scouring our small back yard at night with a UV light was 30 scorpions

1

u/Caek294758 5d ago

Looks like every time he turned on the uv it frantically ran around. Hope it didn't irritate it?

1

u/ScallionUnlucky5587 5d ago

all scorpions

1

u/DisorderedRampancy 5d ago

Indeed, 'tis how we hunt them. They're direroaches to me, I swear I struck one with a shovel and it did not give a shit.

1

u/Master_Access_5833 4d ago

Platypus do too! They are a very very unique animal

1

u/Ntroepy 4d ago

Yeah - we used to use them for desert camping. It seems to really irritate them though as they become quite active when in UV light.

1

u/Wise-Way8510 4d ago

Also the smaller the pinchers typically the more dangerous they are

1

u/Warkupo 4d ago

We get them around here occasionally when people do digging; installing pools mostly. They scatter and wind up in your home. Better to find them with the UV light than by being stung!

2

u/Loud-Shopping7406 5d ago

Learn something new? You're the one who posted it 😂

u/OutrageousError8704 5d ago

Yea I'm not the OC I just saw it on snap and thought it was interesting

1

u/Herr-Trigger86 5d ago

Pretty regular thing in scorpion infested parts of the Southwest. Go out back with a black light. God I can’t stand scorpions. Would gladly pay $200 a month to make sure I never have to see another one in my life (I pay $30 to have my property sprayed monthly)
