Are you wondering about the locations of all Lost Fleas in Hollow Knight: Silksong? These little critters have been scattered all over the lower depths of Pharloom. Now, Hornet has to go and find all of them. Our guide has all the details that you need, so strap in and get ready for a long trek.

Where to find all Lost Fleas in Hollow Knight: Silksong

The Lost Fleas wish/side quest comes from a group of NPCs led by Fleamaster Mooshka. You’ll find these fellas in a zone called The Marrow. From the lower section, you need to climb up past the spike traps and platforms. You should then see a flea signboard to your left. The encampment also has a bench that you can rest on to replenish your health.

Lost Flea #1: The Marrow

Lost Flea #1: The Marrow

To get this Hollow Knight: Silksong Lost Flea, you must reach the top of the central chamber–i.e. it’s the one to the right of the corridors with the fast travel point and bench.

The area above that is filled with spike traps and disappearing platforms. But, if you’re careful, you should be able to get to the top-right portion where the Lost Flea is trapped. Just slash at the vines to free it.

Lost Flea #2: Deep Docks

Lost Flea #2: Deep Docks

This Lost Flea is fairly easy to find… if you know where to look, that is. Basically, you just need to be at the fast travel point in Deep Docks. There’s a destructible wall to the left of the Bell Beast. Pass through the hidden opening and you’ll arrive at a large area with flowing lava and a few enemies. Jump up the ledges and cross the gap, all while avoiding the searing hot liquids, to spot the Lost Flea.

This Hollow Knight: Silksong Lost Flea is also in the Deep Docks region. You must progress further into the campaign until you acquire the Swift Step power from the shrine. Once you have it, make use of your newfound air dash ability to reach the upper-left section of the same room.

Lost Flea #4: Far Fields

Lost Flea #4: Far Fields

Okay, this one can be quite a doozy:

  • Far Fields has a large vertical chamber in the center. You need to go through one of the lower corridors to the left.
  • This path has an exit at the top-left portion, which then loops back to the right.
  • There’s an opening to the right that has a dark tunnel. You’ll get encased in a bone trap as you go further inside, so just destroy it and defeat the enemy that appears.
  • Once that’s done, you should be able to free the hapless critter.

Lost Flea #5: Greymoor

Lost Flea #5: Greymoor

To find this particular Lost Flea, you must head to the bottom-right section of Greymoor. That area has several balloons. You can bounce off of these by doing a “pogo” maneuver–i.e. jump up and do a downward slash. When you’re almost halfway to the top, glide to the right until you see a caged creature. Hit the lever at the bottom to free it.

That does it for our guide on where to find all Lost Fleas in Hollow Knight: Silksong. When you’re done, return to Fleamaster Mooshka in The Marrow. The Flea Caravan will move to Greymoor and you can travel along with them, too.
