Introduction: Why Hunt All Flea Locations Silksong?
Are you ready to uncover every secret in Hollow Knight: Silksong? With the game’s launch sending excitement through the gaming world, one hidden quest stands out: tracking down all the elusive Lost Fleas scattered across Pharloom. These tiny, hopping creatures aren’t just collectibles—they’re the key to moving the mysterious Flea Caravan, unlocking powerful rewards, and earning the coveted Fleafriend achievement. Whether you’re a completionist or just hoping to boost your movement options, this is the definitive walkthrough for all flea locations Silksong players need.
The Importance of Lost Fleas in Silksong
From the moment Hornet steps into Pharloom, players are introduced to the Flea Caravan and its curious denizens. Finding Lost Fleas is more than a scavenger hunt: each one you rescue contributes to the Caravan’s journey, unlocking new map purchases from the merchant Vog and opening fast-travel shortcuts across the world. At 15 fleas, you’ll earn the Flea Finder achievement—but only by collecting all 30 can you claim the prestigious Fleafriend title and the final Caravan reward at Pale Lake.
What This Guide Covers
This complete guide covers all flea locations Silksong seekers are searching for, broken down by region and progression. You’ll find maps, requirements, quick routes, and expert tips for every step. We’ll start in the beginner-friendly Marrow, work through mid-game regions like Greymoor and Shellwood, and finish deep in late-game territory with the trickiest fleas in Wormways and Sinner’s Road. Along the way, you’ll learn which tools to unlock, when to visit Vog for Flea Maps, and how to use the Flea Brew for easier tracking. Ready to become a true Fleafriend? Let’s begin the ultimate Lost Flea guide!
Early Fleas (1-5): Beginner’s Luck in Pharloom
Flea #1: The Marrow
Your journey to complete all flea locations Silksong begins right where Hornet’s adventure does: the Marrow. The first Lost Flea is caged on the eastern edge of the map, just past the intro shaft. Look for a breakable wall; smashing it frees the flea and sets your quest in motion. No special abilities are needed—just basic movement and a keen eye.
Fleas #2 and #3: Deep Docks
As you exit the Marrow into Deep Docks, keep left from the Shakra/Bellway checkpoint. There’s a suspicious alcove near some machinery—slash at the wall to reveal a hidden chamber. Both fleas are found here, tucked away in separate cages. These are some of the easiest to miss early on, so double-check this area before moving on.
Flea #4: Hunter’s March
Climbing midway up the vertical platforms of Hunter’s March, you’ll spot a flickering shadow behind piles of debris. Break through for your fourth flea. Still no advanced skills required, just platforming precision.
Flea #5: Far Fields and First Caravan Move
This flea is a milestone: you’ll find it in an open meadow at the edge of Far Fields, and collecting it unlocks your first Caravan movement—allowing you to shift the Flea Caravan from the Marrow to Greymoor. You’ll also receive the Flea Brew, a handy tool that emits a soft shimmer when a Lost Flea is nearby.

Mid-Game Fleas (6-15): Exploring New Regions
Flea #6: Greymoor
Welcome to Greymoor, a towering city filled with wind funnels and vertical hazards. You’ll need the Drifter’s Cloak ability to ride the wind and reach the top-right tower. The flea waits in a small alcove at the summit.
Flea #7: Shellwood
From Greymoor, head toward Shellwood—no new abilities needed. The flea is on a branch just above the main path, easily missed without a careful scan of the treetops.
Flea #8: Bellhart (via Shellwood)
Continue deeper into Bellhart, using hidden passages in Shellwood. The flea nestles in a nook behind a false wall—listen for its distinctive chirp.
Fleas #9 and #10: Greymoor Dual Spots
After your first visit to Bellhart, return to Greymoor and find Kratt (the caravan’s mysterious mechanic). Two fleas are now accessible in adjacent chambers post-Kratt. Both require clever use of wind currents.
Flea #11: Blasted Steps
You’ll need Act 2 progress to access Blasted Steps. After a grueling climb up a winding shaft, the flea sits atop a precarious ledge.
Flea #12: Choral Chambers
This musical region requires your Drifter’s Cloak. From the right-side bench, dash through timed platforms to a secret alcove. The flea is perched near a glowing choral stone.
Flea #13: Underworks
Drop into the lower Underworks. The flea is hidden among broken pipes near the region’s lowest point.
Flea #14: Whispering Vaults
Descend into the Whispering Vaults’ depths. The path is maze-like, but listen for the flea’s echoing sounds—it’s on a ledge above a pool.
Flea #15: Mount Fay and Flea Finder Achievement
You’ll need the Clawline (double-jump) to reach Mount Fay’s upper platforms. The flea here unlocks the Flea Finder achievement and allows you to move the Caravan to Blasted Steps.
Don’t forget to buy new maps from Vog after flea #15 for easier navigation!
Late-Game Fleas (16-25): Unlocking Vog and the Final Moves
Flea #16: Memorium
Face off with the Giant Flea boss in Memorium’s echoing halls. Defeat it to free a particularly grateful Lost Flea.
Fleas #17 and #18: The Slab
The Slab hosts two fleas in secret passages—one behind a crumbling statue, the other in a hidden alcove accessed via ceiling climb.
Flea #19: Whispering Vaults
This region’s second flea is near shortcut-heavy platforms. Use your new skills to navigate the maze.
Flea #20: Putrified Ducts and Vog Encounter
Meet Vog, the flea map merchant, in the Ducts. After rescuing the flea here, Vog will sell you Silksong flea maps for every region. These highlight remaining flea locations and are invaluable for 100% completion.
Flea #21: Sands of Karak
Use your sand navigation abilities to cross shifting dunes. The flea is buried beneath a sand bridge.
Flea #22: Far Fields Return
With new skills, revisit Far Fields for a flea in a newly opened cave.
Flea #23: Choral Chambers Wind Funnel Secret
Find the wind funnel secret above the main hall. This flea is visible only after activating a hidden switch.
Fleas #24 and #25: Bilewater and Exhaust Organ
Travel via The Mist’s fast-travel system. One flea is in the Bilewater’s flooded tunnels, the other clings to pipes in the Exhaust Organ.
Collecting 25 fleas lets you move the Caravan to Pale Lake—almost there!
Final Fleas (26-30): The Ultimate Hunt
Flea #26: Underworks/Wisp Thicket
Take the bench route and look for a hidden thicket entry near the area’s only lamp post. The flea is camouflaged among purple leaves.
Flea #27: Bilewater Return
Return to Bilewater and check a previously inaccessible pipe (unlocked after a late-game event).
Flea #28: Sinner’s Road
Climb the perilous Sinner’s Road using your latest traversal abilities. The flea waits atop a crumbling archway.
Flea #29: Deep Docks Final Revisit
The final Deep Docks revisit reveals a flea behind a newly opened gate.
Flea #30: Wormways Deepest Path
The last flea is the ultimate challenge: traverse the deepest Wormways paths, using every ability unlocked. Freeing this flea triggers the Fleafriend achievement and allows the final Caravan move to Pale Lake for your grand reward.
Be sure to check your in-game map—any remaining dark flea icons mean you’ve missed one!
