Trouble with Deleting Widgets

For some reason, even though my Primary Widget Area appears to be empty of widgets, a few still appear on the site.

I believe that, rather than dragging the default widgets found in the Primary Widget Area back over to the Available Widgets area, I inadvertently deleted them.

I am using the Twenty Ten theme.

Here is what the final page looks like (with the rogue widgets — Search, Archives and Meta on the right): https://yourtropicalfruit.com/

Can anyone tell me how to remove them?

Thanks!
