Skiekitty............
It's unlikely that you brought them into your garden. Rose curculios are common to our part of the country, but JBs are not.
I never thought I would be glad that I was dealing with curculios, but since they only have a short season above ground and don't attack a large variety of plants like JBs they are much easier to eliminate from your garden.
Good luck with your roses.
Smiles,
