Wishes in Hollow Knight Silksong are side quests you can complete for various rewards. One of the Wayfarer wishes you can get and complete in Silksong is The Lost Fleas Quest. Where you will need to find the five lost fleas to finish the quest even though there are many other fleas to find in the game.
However, for this guide we’re just focusing on the five lost fleas needed to finish this quest. As said there are more than 5 featured in the game..
How to Complete the Lost Fleas Quest in Silksong
This quest is provided by Fleamaster Moosha who is found in the upper parts of The Marrow. This task is to find 5 fleas but remember there are more than five to find in general.
Lost Fleas Location #1 The Marrow

The first flea is situated and found over in The Marrow, the location of which can be accessed after successfully defeating the Bell Beast. Continue on and ring the large bell here to activate a bench and take a rest. The next area is the other section of The Marrow, which was, previously, being guarded by the Bell Beast boss
Activate the switch to give us access to the Deep Rocks below.. Ignore that though, for now. Instead you want to continue climbing up the various platforms ahead. It will lead you to a platform with a Skull Brute and the missing flea is just below
Silksong Lost Fleas Location #2 Deep Docks Bellway

Another flea can be found by exploring the Deep Docks Bellway. Here you will want to destroy the wall located on the left of the Bell Beast area. It is a sort of secret area that we can only find by destroying the wall. This will, then, take us to a lava based platforming area, where our elusive flea hides
Silksong Lost Fleas Location #3 Deep Docks

You’ll be able to get the third flea once you acquire the Swift Step ability from the shrine. Whilst in the same room, jump left across the platforms and hit the lever at the far end of the room. It’ll lower the bell. Jump to the next section above to find the flea.
Silksong Fleas Location #4 The Far Fields

Our next flea is hiding in the Far Fields Bellway, but first, make sure you have the drifter’s cloak from the Seamstress. This piece of equipment will prove to be vital. Once you arrive in the Far Fields Bellway location, you will, then, want to exit and jump across the chasm. Reaching the other side and another room.
Now make your way up and across the many different platforms. Then go to the right side of the room, to find a wall we can smash and a hidden area to unlock
Continue heading upwards to, eventually, find a blocked area. Our little flea is hiding, stuck, behind the containers. Break them to free our next flea.
Alternatively, if you do not currently possess the Drifter’s Cloak, you will, instead, want to make your way to Far Fields by taking the main path. Here we can discover several red ants and a lantern above. Sprint to try and make the jump to the top
Flea Location #5 Hunter’s March

The fifth flea can be found in the Hunter’s March area. After defeating the Big Red Ant boss that is guarding the area you can use downward attacks on the red orbs to help send you up to the next room.
After you’re done, return to the Fleamaster. As a reward, he’ll take you for a ride with the Flea Caravan and also give you some Flea Brew.
