How do you catch Yanma in soulsilver?

Answer 1

u battle it. then throw a pokeball at it. and then u have captured it :)
I hope your a fan of the Pokemon Talk radio broadcast because you have to listen in to that every day until Mary tells you where to catch a Yanma. I am pretty sure you fin it at route 35 but you still have to wait until Mary tells you unless it won't work.

You can catch Yanma both before and after you get the National Dex. It can be found in Route 35 but it is ALOT easier to catch after you get the National Dex. Before it is a 1% encounter rate. Now after you get the National Dex, you can listen to Pokemon Talk on your radio and they will tell you when there is a swarm of Yanma's. When that happens, you can go over to Route 35 and find Yanma alot easier. Before it was a 1%, but now, if there is a swarm, it will go up to a 40%, so it gets alot easier to find.
