Hi, Caroline. I've had problems on our own site with getting a great deal of spam through our enquiry form, even though I took many precautions before finally settling on a captcha. Since I implemented the captcha, almost all spam has stopped (certainly robot-generated spam has).
Given the amount of effort that some hackers appear to be willing to put in to 'cracking' an enquiry form (I don't begin to understand their motivation since the messages are seen by one or two people at the most), I doubt that a 'honeypot' approach will work for long. I like (and use) reCAPTCHA - http://recaptcha.net/ It isn't too challenging to use or to implement. It includes an aural interface for users who cannot see the screen.
