We've been trying to catch carp since some of the other fishing has slowed down, but we can't catch a carp to save our lives and have tried about everything.  So I think we are going to try boilies.  I don't have any idea where to start with them, does anyone recommend a certain brand/type?  (I live in Indiana if that helps).

Use corn

Everyone says corn, but we can't get them to bite on it, and the reservior here is filled to the brim with carp!

 

How do you do it?  Do you just put it on a hook and a bobber, or do you have to throw a bunch of corn out in the water to get them to follow the scent?  Can they find it at night?  

I have never used a bobber for carp. Use a weight .

Canned corn with sodium is more effective than the bagged cut corn. I use about two cans when I go fishing, the great majority of it I use for chum. Chumming has been key for me this year. Use a weight and have your hook on the bottom in the same area as the chum. I think gold or red hooks can help with bites to, but thats just a theory.
