|All Poison Barb Locations|
|1||5% held item chance on these wild Pokémon:
Poison Barbs can only be obtained as held items by wild Pokémon. Specifically you can get this item from Tentacool, Tentacruel, Roselia, and Skorupi. They all have a 5% chance of carrying one.
Of all these Pokémon, the easiest to find in the wild is Tentancool. It is a common wild Pokémon that can be encountered while surfing in most bodies of water in Hoenn.
All Poison Barb Wild Pokémon
Wild Tentacool has a 5% chance of holding a Poison Barb. It is one of the most common Water-type Pokémon you can find in Hoenn, making it the best candidate for farming Poison Barbs – all you need is a Pokémon that knows Surf.
Wild Tentacruel can be encountered on Routes 124 to 134 through surfing. Like Tentacool, it has a 5% chance of carrying Poison Barbs.
However, this Pokémon has a low encounter rate:
It has a 15% rarity in most locations, so it’s generally not recommended to farm Poison Barbs from Tentacruel.
Wild Roselia can be found on Route 117 through walking – it has a 5% chance of holding a Poison Barb with each encounter.
Roselia only has a 20% rarity in this location and can’t be found anywhere else, making it less efficient to obtain Poison Barbs from this Pokémon.
Finding Skorupi (post-National Dex)
Lastly, Poison Barbs can also be found as held items by wild Skorupi (5% chance).
It will only appear in the wild post-game once you receive the National Dex, and it can only be encountered using the DexNav. So Skorupi is really not worth farming for Poison Barbs at all.
Farming Poison Barbs
Among the possible holders of Poison Barbs in the game, you’ll have a better chance of farming this item from wild Tentacool due to its availability in most routes and a high encounter rate to top it off.
You can easily find it on Route 103, so all you need is a Pokémon that knows Surf, and Thief to steal the Poison Barb from Tentacool.
Using Thief as your first move with every Tentacool encounter lets you obtain the item immediately if it’s carrying one, and if not, you can flee on your next turn and try again.

The strategy utilizes Pokémon with the abilities CompoundEyes and Frisk, which increases your chances of encountering wild Pokémon with held items then identifying these items at the start of the battle.
How Poison Barbs Work
When held by a Pokémon, the Poison Barb raises the power of its holder’s Poison-type moves by 20%.
Back in Gen II and III, Poison Barbs only gave a 10% power boost. But in later generations it was buffed to 20% like most type-enhancing held items.
