In the following guide, we’ll explore how and where you can collect all 5 Lost Fleas in Hollow Knight Silksong for Fleamaster Mooshka.
During the Lost Fleas Wish side quest, you will have to track down five Lost Fleas in Hollow Knight Silksong for Fleamaster Mooshka. If you’ve played the original Hollow Knight, collecting the Lost Fleas here might feel similar to grabbing the caterpillar grubs in the earlier title. The Lost Fleas Wish quest requires you to only find the first five Lost Fleas to complete the quest. In this guide, we’ll take a look at the exact location of these five fleas and what you get for bringing all of them back to the quest giver.
Where To Find All 5 Lost Fleas in Hollow Knight Silksong?
All of the Lost Fleas that you need to find for this quest exist in areas that precede Greymoor, with the first one being in The Marrow region, right after you get through the Bone Bottom section. Here’s a detailed look at all of these locations.
The Marrow Lost Flea Location
The sole Lost Flea in this location is just past the Bell Beast boss arena. After defeating the boss, head past the arena and the bench room to reach an open chamber. Before heading to the Deep Docks region by pulling on the lever, head up into a room that sits on top. The first Lost Flea is in the upper right corner of this room. You will need to climb the platforms all the way to the top, right before jumping down, when you defeat the second skull enemy in this area. After dropping down, you will find the flea in some vines.
Deep Rocks Lost Fleas Locations
The Deep Docks region holds two of the Lost Fleas. Refer to the table below to understand where they are.
| Lost Flea Number | Location |
|---|---|
| Deep Rocks Lost Flea 1 | In the Bellway section of the Deep Rocks, smash through the left-hand wall. This wall is to the left of where the Bell Beast is. You might have to jump slightly to break the wall successfully. Inside is a room with some lava and a platforming section. Scale up the platforms and you’ll find the Lost Flea right above the entrance. |
| Deep Rocks Lost Flea 2 | Just after grabbing Swift Step, use the dash ability to jump to the left of the platform where the idol is. Pull the lever to bring a bell slightly lower. Then, use that to jump up to the higher level and grab the Lost Flea. |
Far Fields Lost Flea Location
Far Fields is the next region where you need to go in search of the Lost Fleas in Hollow Knight Silksong. Follow the steps below to reach the location of the flea.
- Step 1: After getting the Drifter’s Cloak from the Seamstress, head to Far Fields Bellway.
- Step 2: Exit the area and jump across the chasm to enter a room.
- Step 3: Head left and then up to enter another room.
- Step 4: In this room, head to the far right end. Smash through the breakable wall here.
- Step 5: Jump up through a couple of platforms. You will spot a passage on the right, which is blocked by some bone containers.
- Step 6: Smash through the containers and break out of the red ant’s cage.
- Step 7: Grab the Lost Flea by smashing through the cage where it’s trapped.

Hunter’s March Lost Flea Location
The final Lost Flea is in the Hunter’s March area. To get there, you’ll first need to defeat the large red ant guarding the area at the extreme right end of The Marrow. After defeating the boss, proceed to the next room. Use your downward attacks to bounce off the red orbs here. You can reach the upper area of the room by doing this. This is where you will find the last flea.
Rewards for Completing the Lost Fleas Wish Quest
After grabbing all five of the Lost Fleas, you have to head back to Fleamaster Mooshka. He will lead you to a section of Greymoor, which enables you to skip past a significant chunk of the main path. You can also speak to the other Fleas at Mooshka’s caravan. Doing so will let you grab an additional reward in the form of Flea Brew. This item will increase your attacks and movement speed for a short duration.
Note: There are additional Lost Fleas to locate in the game, unrelated to the Lost Fleas Wish quest. We’ll update this article with the locations of those soon.
