Exploring all five Lost Fleas location in Hollow Knight Silksong

Of the 30 critters found in Pharloom, collecting five will complete the Lost Fleas quest in Hollow Knight Silksong. Here are their locations:

Location 1- The Marrow

The first flea is located in a chamber above the Bell Beast in the Marrow. Upon defeating the entity, head east towards the bench room. Continue forward to reach a series of platforms leading to the top. Hop on them, avoiding the enemies along the way. Use the collapsing platforms to reach the upper-right corner of the room.

Location 2- Deep Docks

Reaching this flea in Deep Docks requires minimum effort with the Swift Step ability, as it allows Hornet to dash around in the arena. Once you pick up the power from the shrine, use it to reach the platforms on the west. The Lost Flea is located on the top left section of the chamber.

You can also find another critter in Deep Docks beyond a hidden passage. To find it, teleport to the fast travel point of this chamber and reach for the destructible wall beside the Bell Beast. Across the passage lies a room with falling lava. Reach the platform at the top, avoiding the hot fluid, to successfully rescue the flea.

Location 4- Far Field

Navigating through giant rooms in Far Fields can be tricky, but you must take the leap to reunite Hollow Knight Silksong’s Lost Fleas with Mooshka. Teleport to the lower chamber and head left using only the top platforms. Reach for the upper corridor when you hit the wall and go right.

Break the fake wall and pass through the passage to enter the next room. You will find the flea on the upper right segment of the chamber. Free yourself from the trap before rescuing the critter.

Location 5: Hunter’s March

Enter the Hunter's March from the Marrow and rest on the bench to create a safe point. Now, follow the path leading to the upper right corridor and continue forward to encounter a Skull Ant miniboss. Keep moving right until you reach the jumping course. Bounce off the balloons to reach the top right segment of the region, where you will locate the fifth flea.
