How to Tie the Cockroach
- 1
Step 1
Mount saltwater hook in vise. Start thread behind the eye and wrap a solid base to the bend.
Use a strong hook designed for tarpon—they will test your tackle.
- 2
Step 2
Select 4-6 matched grizzly hackle feathers. Tie them in at the bend in pairs, curving outward. The tail should be 1.5-2x shank length.
Match feathers for symmetry—curve them outward for a wider profile.

Step 3
Add 4-6 strands of Krystal Flash along the sides of the tail, slightly shorter than the hackle.
Flash adds visibility in murky or low-light conditions.

Step 4
Tie in clumps of natural brown bucktail as a collar around the shank, building up a 360-degree surround.
Add bucktail in multiple small clumps for even distribution.
- 5
Step 5
Trim the bucktail butts at an angle. Wrap thread over the butts to create a smooth, tapered head.
A smooth underbody makes for a better-looking epoxy head.
- 6
Step 6
Apply flat tape eyes or 3D adhesive eyes to each side of the head.
Position eyes evenly on both sides.

Step 7
Whip finish the thread. Apply 2-3 coats of UV clear epoxy over the head and eyes, rotating the fly to prevent dripping.
Use a rotary dryer or rotate by hand until the epoxy sets evenly.
