you don,t find them in the wild. you can only evolve duskull into dusclops. there. But in the history of R/S/E you can get dusclops. you can,t get dusknoir.......... ONLY WITH A GAME SHARK OR 3rd PARTY DEVICE.
The easiest way is to migrate it from Ruby/Sapphire/Emerald. or go to sendoff spring and see it wild
You can find dusclops in turn back cave.
Aside from finding a Duskull (its pre-evolution) there are two locations where you can find Dusclops in the wild. The first is Sendoff Spring and the second is Turnback Cave. Both of these can be found if you head down from Veilstone City. There should be an opening in the forest on your right.
You can't catch a Haunter in Emerald. You can trade for one, you can find a Duskull/Dusclops at MT Pyre, but you can't straight out find a wild Haunter.
Go to rout 224 and use the pokeradar that's how i got my dusclops.
you find them on route 224
In Pokémon Ruby Version only, players can catch wild Dusclops at the Sky Pillar, Rayquaza's roost which appears only after beating the Elite Four. In Sapphire and Emerald, players must catch a Duskull and raise it to Level 37 to make it evolve. Wild Duskull appear on Routes 121 and 123 in Ruby, and on Mt. Pyre in all three versions.
Lv 40 to evolve into Dusclops. Evolve Dusclops by giving it the Reaper's Cloth (Google to find where that is) and trade.
You can find Dusclops in Pokémon Diamond at route 224. You'll have to use the PokeRadar to find it. It's uncommon and will be level 53.
