- Like its name suggests, the brown dog tick dines on dog blood. But as temperatures rise, they're more likely to feast on you, too. That's a problem, because the brown dog tick is a vector for Rocky Mountain spotted fever, a disease that's deadly to both dogs and humans.

Brown dog ticks are the most widespread ticks in the world, and the most adapted to living among us. Scientists believe they evolved alongside burrowing carnivores like foxes and weasels, and came indoors when we domesticated dogs. That's a problem, because they can transmit bacteria that cause Rocky Mountain spotted fever, a terrible disease that can kill both dogs and humans. Rocky Mountain spotted fever usually occurs in small clusters in the United States and is relatively rare. However, outbreaks in northern Mexico have killed hundreds of people. And rising temperatures due to climate change are sparking some troubling tick behavior. When it’s particularly hot out, brown dog ticks start craving human blood!

Hello! I produced this episode (with so much help internally from the Deep Look team and externally from the experts we consulted with) and am happy to answer your questions! Ask away!
Thank you for taking part and helping make this video possible! ❤
Hi! I just wanted to say that the reason the ticks may prefer humans at that temperature, is probably because our blood is cooler, maybe?
You did great!
Question:
Do these ticks only exist in northern Mexico and southern Cali or are they spread all over the US and Mexico?
Thank you @@FriendlyKat ! Great handle ;D SO, brown dog ticks are all over the world! They're the most widespread type of tick! BUT brown dog ticks that are carriers of RMSF are much less common. There have been outbreaks in AZ and some near the border with MX but currently it's not an issue in CA.
@@KEVROREACTS I had NO IDEA dogs ran at a higher temp than us!!! WOW! You have an interesting theory there! No researchers were ready to postulate for us on this story but maybe you're onto something!!!
Can confirm, after a hike my dog picked up ticks and they all settled on me during the night. After removing them from myself, I checked the dog but she had no ticks on her.
😭
a worthwhile trade
Thats what you get for sleeping with a dog 😂🤮
@@somerandomperson6511that’s the least weird or gross thing someone could sleep with though, besides ticks only got so many places on you you cannot reach or check for
@@somerandomperson6511thats what you get for having a dog.
Ticks, fleas, mosquitoes, and bed bugs are four things that gotta go.
exactly. they have no good reason to exist, other than to be a nuisance.
I'll happily add yellowjackets, bald-faced hornets, Asian giant hornets, horse and deer flies to that list too.
@@Alboravin I have bald-faced hornets all over around my neck of the woods and they're completely docile unless you're smacking their nest with a stick. They look mean but I've never met anyone who's been stung by one. Are they aggressive near you? Yellowjackets on the other hand, are a major nuisance.
@@N20Joe I'm not a huge fan of wasps and hornets in general but bald-faced hornets are technically a yellowjacket, and they are just as aggressive if not more so than their yellow and black-striped cousins when their nest is disturbed, or one of their own releases distress pheromones, etc.
I just made the distinction between the two as bald-faced hornets are quite common and are particularly aggressive when disturbed. As a 'fun fact' they can also squirt venom out of their stingers into the eyes of any vertebrates daring or unfortunate enough to disturb their nests and cause temporary blindness.
If you don't know anyone that's been stung by one then that's anecdotal luck for you. The crux of this all is that most if not all yellowjackets can go in the dumpster fire. I don't care how much pest control they do themselves, I'd rather birds, spiders, dragonflies and other insects do the pest control instead.
Throw in helminths and you have my vote.
Least scary Deep Look video
So your saying a hummingbird is scarier then a tick?
Ong😂
@@BlueBeeXD03 You saw that hummingbird video?! I had to change my underwear after watching it!!!!
@@BlueBeeXD03 BRO DONT REMIND OF THAT VIDEO JEEZ!!!
Then you clearly don’t struggle w/ ticks. Nor do you know what they are capable of. “Scary” is trying to find a lifelong enemy (ZERO redeeming qualities or any worthy purpose for existing in unmolested nature.) that one is unable to see, for the most part, until it’s too late. These loathsome, disgusting creatures are weaponized bio-warfare.
Around my area, we used to mostly only see Lyme disease in the dogs. Now, lots of them get infected with Anaplasma and even Eherlichia. It's scary seeing the trend over the years.
thanks plum island
@@TamponTeaYou’re doing the Creator’s work out here in these algorithmic alleys & cyber side-streets.
"very good boy" was a wholesome and entirely unexpected bit from Deep Look. Please do it again in a future video!
OK, will do!
@@KQEDDeepLookYou guys @ Deep Look are so friendly! I ❤️ yall! And the channel.
My own v v v good boy Henry stars in this video. He's the huskador / labsky on the front end.
@@mimischiffman626 hes so cute
❤@@ahsiek
I love how the science community understands that dogs are very good dogs
It was an observable phenomenon in this case.
@@KQEDDeepLook
In other words.
"We see Good Boi, therefore he is Good Boi"
There's no bad doggo
There's only bad owner
Oh yeah my father got Lyme disease from those. And the doctor doesn't always recognize what it is so if you see a large persistent swollen area don't hesistate to get multiple opinion and early treatment ! Lyme is no joke !
Sorry to hear that. This is a good PSA!
Noticed the dog ticks coming for me from all directions on a picnic this summer, temps were just under a hundred
Not used to ticks marching toward me from a visible distance
That sounds harrowing.
Who was *really* having the picnic?
You or the tics? 😅
@@LightOfHands so it was a ticknic? :P
@@nyan1337the tick's pick and sip
@@TragoudistrosMPHSee… Now THAT’S just excessive. We all know the vampiric insects M.O; we didn’t need the descriptive visuals. I get the feeling that you’re a habitual line-stepper.
Lol-d at the 'very good dog', LOL-d harder at the 'very good human'
Thanks! I'm not sure I would have gone in that box.
*Kudos to the person who volunteered their arm or leg for the sake of this video!*
I volunteered my arm for this! Mine is the less furry arm in the intro and later in the piece. The ticks were known to be pathogen-free and we had eyes on them so they couldn't go far!!!
Rip the person who sacrificed themselves for the video🫡
Got bit by a tick
They didn’t get bit tho at least
One of those arms was mine. The ticks were pathogen-free and they really weren't too hungry for us.
@@mimischiffman626
I was going to say they usually use clean lab-grown specimens for stuff like this, lol. Thanks for taking one for the team!
I got RMSF a couple years ago, it was horrible and got me bed-ridden for a month. It is really hard to diagnose, especially in areas where it didn't use to be common (I got it in Houston). My initial symptoms were a lot of abdominal pain and a never ending fever. I went to the ER and they didn't have a clue. Do a blood test and check your liver enzymes. If you have a never ending fever and your liver is messed up, you most likely got RMSF. Good luck!
Sounds awful! Thank you for the tip on how to spot it.
These things are brutal. Had one a month ago, it left a purple/black bruise on my arm and when I tried to take it out with tweezers, it felt like someone was stabbing me with a blunt needle. I had to go to emerge to get it removed. They ended up cutting it out, that's how deep it burrowed in.
That is incredibly atypical. So much so I doubt your story. Ticks don't "burrow in".
@@michaelinglis567 if he had an adverse reaction to the tick, his skin might have swelled around the entry point and made the tick more “burrowed in” than it initially was
@@somerandomperson6511 Ticks can just stick it in, not burrow further in, since their head and body would stop it LOL also make a habit of checking your dogs/cats and your self before going to bed if you feel the need to go out into long grass like hippies
I got Rocky Mountain Spotted Fever back in the 90's in Tennessee.
The only symptom I had was a big rash centered on the bite, but it was on the middle of my back, so I didn't know about it until somebody else pointed it out to me.
WOW! Lucky they caught that and glad you made it through that experience!!!
@mimischiffman626 Thanks, me too! 😂 We actually thought it was a spider bite before the blood work came back.
It had been a couple months since I pulled the tick off, so I didn't connect the two in my head.
I guess i can't go outside in the summer anymore without wearing my flea and tick collar!
I know it's meant as a joke, but please, folks, don't do that! They are toxic insecticides and should be kept away from your skin. They are marginally less dangerous for cats & dogs, perhaps because they have fur to insulate them from the skin, but they can seriously harm sensitive animals. You can google 'flea collar toxicity'.
OwO
did you tell me i deserve a 'petting frenzy' at the end there
Yes. Yes you do.
Heavily AND frenzied.
Thank you, Deep Look team, for making it possible for everyone to get acquainted with various types of amazing tiny creatures inhabiting our planet, weird at times, yet all majestic in their own way.
"Amazing tiny creatures" is a misnomer. "Horrifying minute bloodsuckers" is a much more fitting name. 🙂
@@buddhacat422 When they get downright into our living space, yes, they should be named the way you suggest.
Both can be true!
@@KQEDDeepLook Certainly! Still, may them better crawl in peace among wild animals like themselves without touching us. ))
Hate hate HATE ticks. They are becoming an issue also here in the mediterranean with the rising tempratures during summer…
"Look at these happy pals" how can I not make you smile a little bit
That ticks me off!
I don't have a dog, and I think 38 °C is the hottest it gets in this part of western North Carolina. I have occasionally caught fleas; I don't know how they got in the house. I've also found a few ticks on myself after I've been in the woods.
Love the opening clip, it’s like she’s saying, “Look! No hands!”
I live in the #1 county in the US for deer tick and Lyme disease. I've been bit twice. As a PSA, I tell you - demand antibiotics if you get bit. Don't take no for an answer. I've worked in homecare, and I once had a client with chronic lyme disease. The poor man was 23 yo, and could barely move or even be touched without pain. I was prescribed antibiotics both times I was bit, and I'm thankful to not have the infection.
Took my
Puppy out side in the 2nd day, came in and saw something on his head, looked, thought it was dirt, brushed it off, next it was on my hand but instinctively I brushed it off and tried to vacuum, was in the bathroom and my corgi was with me and I saw it again on his head, flushed it
Look out, when it comes back again, it's gonna be mad!
Brown dog ticks are hard to kill. Last summer, after I went back inside my house after doing some yard work, I rubbed my scalp and was confused why I had a scab. I didn't bump my head or get cut. So, I pulled the "scab" off, and it turned out it was a dog tick. Luckily, it hadn't full bored into my scalp. I put it in a sealed Ziploc bag, for testing in case I got Rocky Mountain Spotted Fever. That tick stayed alive in that airless bag for two whole weeks. Wow! An insect sealed up like that would probably last a couple hours, if that. Anyway, luckily, I did not get sick.
Mfw my hometown is referenced in a deep look video but it's to say there's a rise in infectious diseases 🫠
Rocky Mountain Spotted Fever is already in Tennessee. A neighbor just down the street got it. This is in crossville.
Great, I needed more reasons to fear ticks.
Glad it was helpful!
Tick, tick, tick...
Our time is running out!
This was a really cool, teachable, and kinda disturbing video. It was good 👌.
Awesome, thank you!
My favorite show of all time ❤.
Hello to you Jake 👋
When it gets hot my dog loves to get in water so maybe the ticks know this, although most humans take regular baths the ticks have not yet figured this out.
Mmmm, my hot dog....
I love the soundtracks you have in these videos - they add a lot! Do you ever release the instrumentals?
funny how all those highly specialized pheremone/molecule/atom detector organs always look like something cobbled together from a scrapyard when zoomed in on.
🤣
another phenominal video and exceptional quality, thanks!!!!
Glad you enjoyed it!
Poor puppers 🥲
Poor non dog owners that not only have to worry about dog poo on the ground now ticks
Love you Laura ! Awesome as always 👍
Producer here. Can confirm: Laura is wonderful!
@mimischiffman626 Well you are awesome too ! Awesome producer.
Ty for great content. This is one of my favorite channels ! 😘
🥰@@GatorLife57
Always be my one of my favourite channel!
I've pulled 3 ticks of my head, neck and one on my shoulder, the last one on my shoulder gave me a headache, very swollen and sore for about 4 days, feeling better now. In Australia Lyme disease isn't recognised?
The last month I've had 3 ticks sorry., treated all my pets with chews, it's that time of year, after some rain, hot weather.
never seen a video or even heard of this channel but somehow i was subbed?
wow! thank you for the tips😁😄😃🙂
Those dogs warm my heart❤❤❤❤
My dog Henry appears in this. He warms my heart on the daily
These need to be longerrrrrrrrrrrrrrrrrrrrrrrrrrrr
There was a tick documentary about a quote epidemic called, The Quiet Epidemic about ticks It's a good watch tbh on this science topic 🎥💯☣
good and informative 👍👍
Thank you 👍
I’ve always wondered why can’t they make a human tick repellent medicine like they do for animals ?
Good info ❤
Oh, great. First, bed bugs, now, dog ticks! 😱
I know, right?
In the 2005 I came back from a summer camp with a tick under my arm, I remember my mother went hysteric then my dad searched in the internet how to remove it
Ish!! I’m sorry about that Antonio
Ticks need to survive after all. Even if it means changing hosts from four legs to two.
That's fair. Ish.
@@KQEDDeepLookI instead propose the ticks go on a hunger strike until the climate is healed 😅
id rather they didnt
great for here in Florida where it commonly gets around 100 degrees 🙃
I really miss rambling through woods and fields without cover-up gear on my lower half. Now i can't even risk it in hot weather?!
Oh, I know all about how they dig in -ugh! Living on ranch sorta forces you to know. 😆🐶
shout out to the dogs that volunteered man
This is what we get for bringing animals into our home
I purchased Bravecto for my dogs. Haven't seen a tick on them for about a year now.
Hello! I'm just curious is it also the same as the ticks in Asia? Specifically in tropical areas? Thank you!
Am I the only one who thinks that the way the ticks walk is kinda funny?
2:46 an inquisitive and patient scientist.
if there was one animal that was extinct without any consequences it would be ticks, I got bit by one once and I felt violated.
And bedbugs, and the American cockroach 😭
THIS ENRAGES ME
Just coincidence that they gravitate towards us when the temperature hits what the human body sits at?
Right?! So interesting!
Maybe we're cooler than dogs' bodies are so our blood would be cooler overall as well when it gets too hot out for them? Great video!
Someone else suggested this too and in reading their comment I learned this fact! Mind blown! Maybe this is why! Researchers we talked to were hesitant to draw conclusions on this at this time!
@@mimischiffman626 That's fantastic! What a great episode and production! Thank you for your reply!
Props to the person who volunteered to be bitten by the tick
Awesome video

😅lol why
@@Austinmich Because these beasts want blood. Ours
@@kennethmarshall306 Lol that’s true. I hate ticks and bugs. lol. I run away from it.
do you have a dog?
@@Austinmich no. Maybe just as well. It might bring in these uninvited guests.
Thanks to all pet owners.
These video titles are like headlines from the 70s 😑
Ok, whoever put that thermal vision of the fox is a creative genius
Kia Simon who does the fancy edits for the show and who helped conceive of this episode to begin w was the genius behind bringing in that shot!
Found one of those between my pinky toe, and from the size of it seems like it was there at least two or three days...
they really did put a really good dog in that box 🥺
so creepy but informative
I wonder if it has to do with body heat and the viscosity of blood.
I put a big one on an ant hill and they all started pulling on it from different angles. They slowly just started moving it away from their entrance.
As soon as this video ended i found a tick crawling on my dog. 💀
Why do ticks suck blood many times its body size that it becomes practically immobilized and therefore vulnerable?
Ask Satan, the guy who made them.
Ask Satan, the guy who made them.
Well when they've eaten enough, they drop off naturally. Most animals don't notice or can't get to an attached tick, so usually all they have to worry about are birds. We humans just happen to be dexterous and keen on grooming, and we don't have fur so it's easier for us to find and remove them.
Phew. No mention of them here in the UK. 😅
I wish this or lyme disease were my biggest concerns with ticks. Australia has a tick that causes progressive paralysis and respiratory failure thanks to a toxin they inject.
🙀
Listen, Australians. You need to stop bragging about how a murder hobo designed every creature and plant on your continent. You might peer pressure the rest of us into an arms race. 😂
Idk how people survive in Australia.. everything there is bigger and more possed off/wants you dead.
Australia is a dangerous place 😂💀
A very reassuring title
mine is the cat tick
i remembered that i used to had a cat , that the tick was so huge , and my cat had bad swelling , it took about 2 weeks getting weak and lost appetite , my cat don't dare to pick off the tick, it must be hurt...
so i bring it to the vet to done the job.
thank god, both my cat and dog are outdoor pet, so i won't go through this
With Laura magic voice I am not afraid of ticks. 😂
I guess the human trials for the tick & flea treatments are getting close to completion.
Dogs don’t sweat and the ticks seek humidity, maybe our sweat just gives them more to hone in on when it’s hot out?
Interesting hypothesis
Thank you for calling it a very good dog, it looks like a very good boi
"When it's par-tick-ularly hot out". Oh yes.
“They can transmit bacteria that causes Rocky Mountain spotted fever” proceeds to let a tick bite their arm.
Jokes on the tick because my blood is 25% thc and 5% hot sauce 🤣🤣🤣
Using that powder that dries them up still works right???
I'm guessing 38°C is hot kinda hot and ticks would perfer to feed on something less hairy.
I was worried they were gonna make the dogs pay for the tick medicine
Slab Dogs United would never.
guys that bug crawling sound freaks me out whenever its not a cute bug
My first time hiking awakened my tick phobia
Hi Lora!
I'm watching this at 1 am and alas, I'm afraid to sleep!
as long as there're screen. we are safe i guess
Reminds me of The Fifth Season by N.K. Jemisin and organisms radically changing their behavior to survive... not to our benefit...
Yeah that's kinda what nature does. We don't matter, not to mention we are a pest and a disaster to plenty of places as well.
Idk why but the music almost reminds me of Invader Zim lol.
Notif squad ❤ also i hate ticks 🥴
I saw 'dog tick' and had to mention this. I once found a dog tick in my belly button, I have no idea how long it was there just felt it taking a shower one day. Ever since then I make sure I wash inside my belly button, every day.
I experienced having a dog tick in my head...
