Those are breadcrumbs. You can completely remove them from all pages by adding the following line into your own layout.xml file.

You can define your own layout.xml file for your module by adding something like the following into your magento modules config.xml

<frontend>
    <layout>
        <updates>
            <namespace_module modules="Namespace_Module">
                <file>namespace_module.xml</file>
            </namespace_module>
        </updates>
    </layout>
</frontend>

Then the layout.xml file would look something like

<?xml version="1.0" encoding="UTF-8"?>
<layout>
    <default>
        <remove name="breadcrumbs.container"/>
    </default>
</layout>
