According to the article I linked, MESSENGER should be able to detect vulcanoids 15 km or greater in diameter. I wonder how many [if they exist] are smaller than that, however.

Quote:
"With MESSENGER, we can search for vulcanoids as small as 15 kilometers across,"
And considering vulcanoids [if they exist] are obviously between M and Sol, there'd be little [angled-away] to no albedo to search for/attempt to detect towards confirmation/discovery.
