Need advice growing Sandspurs/helping fireants

I live in the Tampa Bay area and need to cultivate sandspurs on the
turf portion of my lot. What is the best way to start a sandspur
grassplant from spurs? I just collected a quart worth of green and
brown spurs from the local beach access and want to get them started
soon.

Also, I am interested as to how to best transplant a colony of fire
ants, once again, on my property. In this case, what conditions would
most encourage the queen to nest in my turf in a particular area.

Thanks in advance.

Oh - In case you are wondering why, here's the background.
I live on a corner lot and there is a particular neighbor that insists
on parking his vehicle{s} on the piece of my property that is part of
the streetside public easement. It all started when he was first
constructing his house and he parked trailers there, with the
understanding that after construction was finished, he would reseed
the strip and get the stuff off. It's been two years now and even
though the trailers are gone, he parks his truck there all the time.
His new rationale (despite having his own 2 car garage and a driveway)
- it's public property in the easement (eventhough I pay to maintain
it) and the cops tell me its OK to park there. Part of the rationale
is also because we are snowbirds, we aren't there, so there. Not only
is this guy doing it, but other neighbors think it's OK too.

There's not too much I can do with the strip of land, since it is part
of the public easement, so I figure sandspurs and fireants could make
it a little less appealing for parking(heh heh) and I still remain
within my rights and responsibilities as a property owner and good
neighbor.
