From there, you see an exit to the south. Go out through that exit and you will be in an area of Route 104 that you couldn't reach. Go south and check on the item to get a Poké Ball.

Return to Petalburg Woods and go west, then north. You find Bug Catcher Lyle. He has level 3 Wurmples (six in Ruby/Sapphire, four in Emerald). Northwest of him, there is a Parlyz Heal.

Go east from there, then north. You see someone looking around. He is a Devon Researcher. A Team Magma/Aqua Grunt attacks. The grunt has a level 9 Poochyena. After the battle, the researcher gives you a Great Ball. This is a better version of a Poké Ball. It has a better chance of catching pokémon. After that, go north, then west. There is a hidden Poké Ball in the corner to the west. Go north and you find Bug Catcher James, who has Nincada (a level 8 Nincada in Ruby/Sapphire, or two level 6 Nincadas in Emerald). North of him, you find an Ether. East of there, some trees are blocking your path, so you have to go north to leave the woods and enter the northern part of Route 104.
