I noticed that both of my neighbor's front lawns have crab grass that
are slowly making their way to mine, is there any way to form some
sort of barrier to keep them from getting on to my lawn? I heard rock
salt and water can kill crab grass is that true?

I suspect that rock salt would kill everything. Pre-emergent herbicides
are only selective one
that works for crabgrass. Timing has to be right, and you can probably
spray some well over
the property line. Nasty stuff for wildlife, so use only according to
label.

Whats wrong with crab grass killer? If your lawn is well managed, it should
be hard for that to infiltrate.

I'd rather use non-toxic methods since my children play on the grass.
Any better options than hand raking?

It's going to be an ongoing battle unless you can eliminate it from your
neighbor's yard as well.

Can you make a perennial bed along your property line and use mulch to
keep things in check?

Depending how bad the crabgrass is, you might be able to use a propane
torch and burn it.

Work with your neighbor to resolve the problem.

If it's visible, it's too late for the pre-emergent, anyway, which
should have been applied in May-early June time frame (earlier/later
depending on your unstated location). Once it's applied and watered
in, there's no issue anyway.

After it's growing, topical applications aren't particularly effective
and will damage most other grasses as well (again, to a greater/lesser
degree depending on species, growing conditions, etc., ...).

Other than removing it manually and mowing infestations short and
removing the clippings and preventing it from going to seed as much as
possible (it's an annual so each year's crop is from seed left from
previous or earlier years, hence why the pre-emergents are effective if
down early enough so there there to stop the seedlings from surviving)
are about the only control techniques. As somebody else noted, as long
as there's a seed supply, you'll have a continuing problem.

Mo' defenently if concentrated enough to kill the crabgrass...and will

Pre-emergent herbicides are only selective one

And other than Siduron they're really not particularly selective--others
will at least inhibit severely virtually any germinating seed at the
time they're still active.

Well thats simply not true.
My lawn next to the road develops crabgrass regularly.
CG killer works just fine without hurting the other grass.
Maybe it hurt grass other than KB, fescue, and rye; but it is fine on
those.

Use a barrier - either edging as suggested by some others, or set up flower or
evergreen beds with mulching, depending on your particular layout and size of
lawn.

But, y'know, this is like the dandelion thing. Having such a high standard for
a lawn that the Rest of the World has to keep to the same high standard to
enable it may be a little - unsustainable.

Roundup will do it, available at any hardware store or big box, but be
careful - it kills anything green, such as the surrounding grass.

Which of course isn't going to help his problem, as the crabgrass is
on the border between his neighbor's lawn and his.

Acclaim is the most effective post-emergent product I have used. Far
better than any of those typically found in garden centers and if
applied correctly, not damaging to typical turf grass. You can find
it at agricultural supply shops. Otherwise, the other choice is one
of the typical selective herbicides sold at lawn/garden, HD, etc.
One key is to nail it when the plants are as small as possible.
