Ugh... these things are everywhere... definitely in places where they can germninate and places I do not want them to germinate! What can I do?

I was considering getting out the shop vac. Once they do sprout, they are so stemmy that they're difficult to pull. So many of them too!

Can I simply spray them with something?

I've lived here almost 10years (old Denver neighborhood) and I've never seen them do this like they have the last couple years. I wonder if my neighbor stopped spraying them and if this is the cause.

Thanks for your input.
