I've an unheated garage many years old.

How many? *Also is it attached to the house or 'free standing'? *Both make a
difference.

One side the concrete floor
meets the wall (wood beams) just fine; but on the other side a gap of
about an inch or two can be seen along a length of at least 20 feet.
Critters see it too and worm their way into the shelter...

If attached to the house, much more of a problem and a more solid 'fix'
needed.

First - is this gap indicative of a greater problem in the garage (the
wall is solid and straight)

Depends on how old it is. *Say, 20-30 years, and hasnt changed in last 5-10,
not a problem.

and secondly, how can I seal this gap...?
Add concrete...? *Patch with 'hardware cloth'...?

Hardware cloth will not work more than a very short time. *While another
suggested mortar (a very possible solution) it may not be easy to apply
depending on the design of the fill area and my be pretty unsightly both
based on that design, and your skill level. *If your skills with it arent
pretty good, you will create a potential 'hack looking job' that can drive
off a buyer if it's attached to the house. *Less so if a free standing unit
and not apparent from outside of it.

I can think of several simple fixes that would work in most climates but
they make presumptions on the construction of the 'wall'. *Will work for
attached garage or free standing sorts.

1. *If it's pretty much a bare wall with studs on the inside and some sort
of exterior siding, get some of the blue foam largish squares and cut panels
in that about 1ft tall and run them down to the floor using 3 layers at
least. *Set these in a bottom of thick layered caulking. *Over the studs,
you may want to add that sort of board with the holes in it you can add
hooks to for tools, floor to 'top'.
* *- This presumes no real drywall etc is there already, water doesnt come
in the gap due to landscaping or area
* *- If presumptions are right, the smart thing is to insulate all the way
up as it's real easy to just add some rolled 'pink insulation' between the
studs at this stage then add the simple 'pegboard' (I believe that is the
name of it). *You may want to do the whole garage with it.

2. *If you do get water flow in there, you wouldnt have drywall left so we
can rule that out but you need a proper water barrier. *Mortar is good but
you'll want to cover it with 'peg board' as in #1 above unless you know how
to do it really well.

3. *If you get no water, and do have something like drywall or perhaps
paneling of some sort, I'd fill the gap tightly with thin 'shim wood' and
loads of caulk all coating everything, then put up a baseboard on the
inside. *The wood in mind is sold in 6-8ft lengths and you'd add it
'longwise' (same orientation as the wall).

Add more information on the circumstances and we can help narrow this down
for you better ok? *Nice folks here but there were too many variables left
to really answer.

Is detached from house; nothing structurally has changed in many
years; dry - but wall in uninsulated (no drywall, etc.)...

Thanks, again.
