Look, I’ll be honest: when I dove back into Hollow Knight: Silksong in 2026, I did not expect my late-game life to revolve around rescuing 30 misbehaving fleas from every cursed corner of Pharloom. But here we are. Hornet is apparently a full-time flea therapist now, and if you want that juicy

Egg of Flealia

plus the fourth Needle upgrade, you need to catch them all.



Let’s get one thing straight: this is not a quick errand. In total, there are

30 Fleas

scattered across Pharloom. Almost every Flea can be found in

Acts 1 and 2

, but you’ll need nearly every movement ability—except

Silk Soar

—before you can reasonably grab them all. Yes, that means you’ll be returning to areas you thought you’d escaped forever.







The Flea Caravan Milestones ?



The Flea Caravan does not move just because you ask nicely. It moves based on how many little idiots you’ve rescued. Here is the threshold table I wish I had from hour one:






Fleas Found


What Happens







5


Caravan moves from

Marrow

to

Greymoor






15


Caravan moves from

Greymoor

to the

Last Judge

boss room in the

Blasted Steps






25


Caravan reaches its final home in the

Putrefied Ducts






30


You get the

Egg of Flealia

and unlock the real party






That middle stretch between 15 and 25 is pure emotional damage, by the way. The game suddenly remembers it has platforming, and you will remember you have no Silk Soar.



Where the Little Monsters Hide



You’ll be sweeping through a ridiculous number of zones. From my notes, the big ones include:






Marrow

– the tutorial fleas, deceptively easy







Deep Docks

– wet, dark, and full of regret







Far Fields

– scenic, until you fall into the spikes







Hunter’s March

– lots of vertical climbing







Greymoor

– moody, and the second caravan stop







Shellwood

– I got lost here more than I’d like to admit







Sinner’s Road

– honestly, the name says it all







Wormways

– cramped tunnels and bad decisions







Underworks

– hidden corners everywhere







Choral Chambers

– pretty, but the fleas are tucked behind some nasty jumps







The Slab

– feels like a boss arena, but no boss, just fleas







Whispering Vaults

– echoes and anxiety







Mount Fay

– cold and high







Bilewater

– gross, bring a towel







Sands of Karak

– the final stretch, bring your patience














A few specific Fleas are tied to unique NPCs:

Kratt

,

Vog

, and a truly enormous

Giant Flea

. You’ll need to interact with them in the right way, which usually means listening to their weird dialogue and then doing a ridiculous favor.















The Final Reward ?



Once you’ve rounded up all 30 Fleas, do not just stand there admiring your achievement. Go talk to

Fleamster Mooshka

in

Fleatopia

. They’ll reward you with the

Egg of Flealia

. This little treasure decreases the cost of

Silk Skills

whenever Hornet’s HP is full. It’s basically a reward for perfectionists, and it’s extremely strong if you play carefully.







But wait, there is more. When you return to

Flealia

after collecting all 30, the Fleas throw a celebration and you can take part in three minigames:





?

Juggle

– keep the flea airborne without losing your mind






?

Dodge

– avoid getting slapped by everything






?

Bounce

– timing-based nonsense that feels amazing when you win






Beat all three, and you’ll earn the fourth and final

Pale Oil

, which gets you the

fourth Needle upgrade

. That is the real dopamine hit at the end of this whole flea circus.



So yes, collecting every Flea in Silksong is absolutely worth it, but please learn from my mistakes: unlock your movement abilities first, use the maps, and do not attempt the

Sands of Karak

section before you’ve had a snack.



Just like mapping out every Flea location takes patience and the right tools, snagging the best deals on games and accessories requires a bit of strategy too. If you're the type of player who likes to complete every collection and maximize every reward, you'll probably appreciate keeping tabs on price drops before your next big purchase.



Instead of refreshing store pages every day, you can set up alerts and let
this price tracking tool
do the heavy lifting. DealNest watches prices across retailers so you know exactly when to strike, kind of like knowing the perfect moment to grab that final Flea before the boss fight rolls in.
