I've been rescuing my lawn "slowly" since I bought my home about two
years ago. All big jobs are done for the renovations I had done.

I've worked to rescue the landscaping since then; irrigation, fescue
lawn / desert landscape. Remove trees, shrubs, put new trees in, etc.
Find lost drip emitters and fix irrigation.

I over compensated watering the back lawn areas this summer, trying to
hold the lawn in a blistering summer - 100F +

Now I have slugs and these small bugs that curl up in a little ball.

I'm correcting the water issue by the timer.

What are the armor looking bugs, all curled up in a ball.

Kids call them "rolly pollys", aka pill bug, aka sow bug. They're actually
the wood louse (Porcellio scaber). They're also actually a terrestrial
crustacean, and not a "bug". They're found in damp areas, usually with some
sort of rotting vegetation or wood. If you've been over-watering, then
that's most likely the reason for their appearance. They're not really a
threat to your lawn, but they're easily controlled with a pesticide
specifically designed for crawling insects, but if the conditions remain
favorable to them, they'll return.

As for the
slugs; I will be after them, but in a desert I never had slugs before.

Again, watering conditions brought them about. They're most active at
night, so avoid watering in the evening. If they're only in certain areas,
you can bury a jar lid, upside down, even with the soil. Fill the lid with
beer, and they'll crawl in and drown. Not a bad way to go, if ya gotta go,
eh? =)

Either way, if you get your watering schedule under control, I doubt you'll
have either of these pests for long.
