Choosing the Right Senko Size

Senko worms come in different sizes, and choosing the right size depends on the conditions and the bass's feeding mood.

3-inch Senko: Best for finesse fishing and smallmouth bass.

5-inch Senko: The most versatile size.
6-7 inch Senko: Best for big bass and aggressive fish.

Best Conditions for Senko Fishing

Spring: Best for spawning bass using wacky and Texas rigs.
Summer: Fishing grass or offshore structure on a Texas or Neko Rig.
Fall: Bass feed aggressively, making weightless Senkos a great choice.
Winter: Use a slow, dead-stick approach to tempt lethargic bass.

Tips for Fishing Senkos

Let It Fall: Most strikes occur as the Senko falls, so avoid overworking it.
Use a Wacky Rig: Creates more movement and works well in clear water.
Fish Near Cover: Target grass edges, docks, and brush piles.
Try Different Colors: If bass aren’t biting, switch colors based on water clarity and light conditions.

Conclusion

Choosing the best Senko color depends on water clarity, lighting, and bass behavior. Colors like Green Pumpkin and Watermelon Red Flake are excellent all-around choices, while Black and Blue and Junebug shine in darker water. Experimenting with different colors based on conditions will help you increase bites and catch more bass using Senkos.
