Remove Bullets from Category List widget and Blog list

I am trying to remove the bullets from Blog posts and from the Categories list.  I'm using version 7.3.  Any ideas how to remove them?

Use CSS to target the ul and do list-style: none.  Sitefinity classes everything so you can look in the widget template or inspect the Dom to find the class 

Thanks!  I'm unsure what you are referencing when you say Dom?  Where is that located?
