His personal website boasts that his clients have included or currently include "chemical and pharmaceutical companies, think tanks, trade associations, service providers, publishers, authors, and others. Since the 1990s, he has been the public relations counselor for the New Jersey Pest Management Association. For ten years, he served as the Director of Communications for the American Policy Center." 
Caruba maintains several web sites:
Between 1989 and 1997, Caruba edited a media directory, Power Media Selects for Broadcast Interview Source, a Washington D.C. company.  Caruba is currently listed as a contact for journalists as a public relations expert on the following websites run by Broadcast Interview Source:
Need for disclosure
In 1989, identifying himself as a Public Relations Counselor, he wrote that there was nothing wrong with PR professionals producing PR materials, as long as they disclosed that this was what they were doing:
Many NASW [National Association of Science Writers] members, including myself, function both in the field of public relations and independently as authors of factual articles and other literary materials. So long as we properly identify ourselves as regards these separate activities, nothing, I know of can or should forbid us the right to pursue these two activities.
In a January 2006 column, Caruba railed against the decision by the Scripps Howard News Service to drop Michael Fumento as a columnist after Businessweek revealed he had been funded by Monsanto for his 1999 book BioEvolution. "Courageous journalists that they are, Scripps dropped Fumento without even contacting him to determine the truth or falsity of the claim of bias leveled against him in a Business Week column," Caruba complained.
Arguing that the book was accurate Caruba described the Businessweek article as "nothing to do with his ethics and everything to do with a leftist attack intended to smear his reputation and hopefully remove a leading critic of environmentalism and other manifestations of dubious science intended to frighten people." 
Caruba brands SourceWatch a "front group"
In a comment appended to one of his own articles, Caruba attacked SourceWatch as follows:
- May I suggest that, instead of SourceWatch, a Green front group that exists to demonize anyone who is a critic of the endless scare campaigns of the environmental movement, that you simply visit www.caruba.com where I provide a complete set of "credentials" that includes membership in the Society of Professional Journalists, the American Society of Journalists and Authors, and the National Association of Science Writers. Everything I write is, to the best of my ability, carefully documented. Do I think the environmental movement has an agenda and no sense of ethical behavior? Oh, yes! 
He did not explain who he believes SourceWatch acts as a front for. The Center for Media and Democracy, which sponsors SourceWatch, publishes an easily-accessed list of its major donors on its website.
