Stomping for Zeresh

Kvod Harav,

Why do we only stamp out or drown out the name of Haman, but not of his wife who suggested to Haman to build the gallows and hang Mordechai upon them?

Thank you!

Not sure if I understand the question.
People always talk about Hitler when they refer to the most atrocious mass murderers. There were a lot of Zeresh’es from that timeframe that are seldom mentioned. We refer to Haman and we have in mind his entire clan.
