it's an intresting request.

why do you need to block google and yahoo from your sites?

 

Yep Trichnosis! its very interesting. why do you want to block yahoo and google?

 

Anyone know the name of the Google bot that crawls the Adsense on your site?

 

Its:
User-agent: Mediapartners-Google

 

I'm testing BH script and don't want to get IP banned

 

Are you looking to block these three bots only? or other bots as well?

Because if you want to block bots in general then just write the following

User-agent: *
Disallow: /whatever/
