Silksong Lost Flea locations
Where to find the Lost Fleas in Hollow Knight: Silksong
Finding The Lost Flea locations in Silksong will help you complete one of the many side quests you can pick up on your adventure through Pharloom.
The Fleamaster has lost their beloved Fleas in Hollow Knight: Silksong, and Hornet's been asked to free them (once found of course.) There are a total of 30 Lost Fleas to find in sets of five, and they're quite spread out so you will need to do some hunting…
On that note, here's our in-progress Silksong Lost Flea locations, including how to start The Lost Flea.

We're updating this section as we find them!
Flea One - The Marrow
The first Lost Flea can be found in The Marrow after beating the Bell Beast. We've marked their location on the map below:
Once you've defeated the Bell Beast, keep heading right (activating the Bench you pass on the way) and then keep heading right until you see a lever with platforms above it.
Climb up these platforms and follow the path here upwards until you reach the next area. In this next area, head left until you come to some spikes on the ground. Be mindful of the enemies here and navigate the platforms to the left, then head upwards. When you can't get any higher go right until you reach the larger platform with the skull spider enemy on it.
From this enemy, head upwards, to the left then up and across to the right. You will encounter yet another spider-like enemy on a big platform. On this platform, head right to the edge and stop. Pan the camera down to see a small ledge below you, carefully drop down here.
Once you land on the ledge, head across to the right and you'll soon find your first Lost Flea. Attack the tangled mess they’re stuck in to free them.
Flea Two - Deep Docks
You can find the second Lost Flea when you enter Deep Docks from The Marrow. You can find their location marked on the map below:
Head into Deep Docks then drop down to where you find Shakra here, then take the passage to the left that leads you to the Bellway. Cross to the opposite side of this area and attack the wall here to reveal an opening.
Head through the opening to an area where large streams of lava are falling from the ceiling. To find the Lost Flea you need to use these platforms to climb upwards to the left side of the room. Wait for gaps in the falling lava to move.
Once you've made your way up and across to the left, look to the right to see another platform. This time, you need to follow the platforms here to the right by again timing your jumps with the gaps in the lava.
When you've made your way across the platforms you should be able to hear the Lost Flea. On the smallest platform before a lava stream, look down with your camera and you should see the platform to the right with the Lost Flea on it!
Flea Three - Deep Docks
To find the third Lost Flea, head to the point in Deep Docks where you get the Swift Step ability (which is basically a dash ability). You can find the Flea's location marked on the map below:
From the point you get Swift Step, head to the left and use your new 'dash' ability to get across to the next floating platform here. Keep doing this to follow the platforms to the left, until you come to one with a lever on it.
Attack the lever to get it to lower a platform to your right. Jump onto this platform then use it to jump upwards to the left and then jump across to the right. You should see the Lost Flea stuck here.
We will continue to update this page as we find more Fleas!
How to start The Lost Flea in Silksong
To start The Lost Flea in Silksong you need to find the Flea Caravan in The Marrow. To do this, head right from Shakra then down to a room with lava in it, continue across this room then up and to the left. You should see a sign here with a Flea on it, then keep heading left to run into the Fleamaster. Speak with them to begin this quest!
Remember, though there are 30 Lost Fleas to find you need to find them five at a time!
