Spring is here, and with it, the start of flea season. With the warming weather, people and their pets are spending more time outside - which increases the chances of bringing home a hungry “itch hiker.”
While pet owners curse the tiny insects and look for a way to rid them from their homes, it turns out fleas actually perform some remarkable athletic feats, like jumping 50 times their height - the equivalent of a human jumping 300 feet - or leaping so fast that they take off 100 times faster than the blink of an eye.
No larger than a sesame seed and flattened side to side, fleas can slip through fur with ease. Their jump is so fast they seem to simply vanish and reappear somewhere else.
“It's there and then it's gone,” said Gregory Sutton, a professor of biomechanics at the University of Lincoln in the United Kingdom.
--- What do flea eggs look like?
After feeding on blood, adult fleas mate and lay eggs. The eggs drop out of their host animal’s fur or feathers and into their bedding or nest. The eggs are translucent white and very small. At 0.5mm the eggs are about the size of a grain of salt.
--- Why do fleas bite me?
Blood is a protein-rich food for fleas. Adult fleas feed on blood before they can procreate.
--- Why does my dog/cat keep getting fleas?
Fleas are nest parasites. Their eggs fall from the host animal into its bedding where they hatch. The worm-like larvae feed on organic debris (including the adult fleas’ feces) in the bedding. They then curl up into a cocoon and undergo metamorphosis into their adult form. Flea baths tend to kill the fleas currently on the pet, but there may still be flea eggs and larvae in the pet’s bedding. When those young fleas mature they may reinfest the pet.

“That’s unlucky if u have fur or feathers”
Reptiles: *yes.*
Reptiles have their own parasites to worry about, mites. And they're even worse since they squeeze between scales where you can't reach them period.

Watching fleas in 4k, exactly what I needed in my life at 2 a.m.
Mi 28 I used to wake up at 2am with at least 10 or 15 on one leg
Why am I reading that at 2 a.m.?
Same lol
Why is it 2:30 rn and im reading this also? O_o
dats me
imagine how terrifying it would be if the fleas were gigantic.
I think the force would break sidewalks lol
@PC Mehetmed Armitige
I think humans have already eradicated themselves before that even happens xD
@PC Mehetmed Armitige they'll die because of size differences, those MFs aren't meant to become huge like us, unless something changes to their survival strategy~ 😹
Actually. They are life sized.
I wish they were bigger tho. Just like how huge flying cockroaches are scary and all but they're just so much easier to kill
I feel itchy watching this
Yaa gotchaa
yep and it just makes me more paranoid

Quick tip: Original dawn soap kills fleas instantly.
So bath cat in original dawn soap??
@@P_steez you could if they don't mind water. I think there is also dry flea and tick shampoo which they might prefer, make sure they don't lick at it.
@@drea6717 thank you so much, I knew about the oil clean up stuff but I wasn’t aware dawn soap could easily kill the fleas, is it through suffocation?
@@P_steez you’re more then welcome🙂 not through suffocating but the soap coats the fleas otherwise buoyant body and causes them to sink and drown
Works every time if you let it sit

Fleas are actually really fascinating creatures. It's hilarious how they ragdoll when they jump X3.
We agree!
“Ragdoll” *roblox ragdoll game flashbacks*
They've been living off me for years. I've gotten very good at killing them. I just put them in between my fingernails and pop them, they are still alive but that gets them to stop moving long enough for me to use the tip of my fingernail to split them in half. Also got a bowl of 🧼 soapy water and caught over 100 of them yesterday and 25 so far today

Never knew fleas literally just Yeet their selves onto something. I always thought they had guided jumps until i saw this video lol
1:10 wonder why fleas are so slippery they have a mustache
So that means the next logical step in their evolution would be a grabbing hand with an opposable thumb so that they can twirl their mustache.

“You can’t squish fleas”
....oh, yes you can 😂
Only if pinched between super hard fingernails or tweezers. That is distinctly different than mashing or squishing.
just squish it with your nails. That’s still squishing.
My mom just burns them
Lonely My mom drowns them.
Lonely yeah I burn them too after catching them on duct tape. Unfortunately they don’t stick well to it so you have to burn them fast before that can leap off. Another way to catch fleas is just leave small bowls or pans of water on the floor. Eventually the fleas land in them and drown
"Like a little sesame seed with legs."
And then no one ever looked at sesame seeds the same way again.
Mom's "take a gigantic leap of faith" suddenly gets a whole new meaning.
Try to squish them?

i do that to

Just wash cat and cat bed every 3 days
eatan111
wash cat bed, yes. for cat, washing every 3 days is excessive. if you pet your cat often and pay close attention, you'll notice the flea dirt long before you even see any fleas. it's very easy to see. so as soon as your cat has even just one or two fleas on her, you should already know about it if you're paying attention. then a flea comb can get rid of them if the problem hasn't gotten out of hand yet, and if it has, you'll need frontline for cats. my current cat is almost 2 and has never had a flea before. my last cat lived to be 22, and in his life, he did get fleas a few times. but after frontline, they were gone for years until another came along.
if you have an outside cat in an area with lots of other cats and creepy crawlies, you might need to switch to a proper flea medication regimen. but i like to keep medication like that to a minimum if it isn't needed.
2:46 “A few days later...voila. All grown up.”😆

If a Flea was the size of a Human, they can jump over a 10 storey building easily
Just A Dio Who's A Hero For Fun but then it’d weight about 150-200 which would make it heavy so flying so high wouldn’t be a option
