Which troops are best against traps

Where can I find information on what troops do best against specific traps at a castle we are attacking?

Only one of the artillery types, Mortars, have an increased attack against traps. Having the other type, Cannons, in your troop composition can help absorbing damage from any of the traps. There is no difference for the trap type. The different traps each are stronger against different troops. Information about that can be found in your Trap Factory building. Often it is better to just focus on troops, as there are way more troops than traps in defending parties.
