It is a PokeRadar Pokemon, which means you have to use the PokeRadar and enter the patches of grass which the PokeRadar indicates. Repels of any kind should be used while using the PokeRadar because you can be interrupted while trying to get to the indicated grass patch. Note that Repels do not repel PokeRadar-indicated Pokemon.
