How to fix a through hole in stucco on the outside of the house?

Question

Some contractors drilled some holes on the outside of the house and I need to patch them up.

One hole is about 1 to 1.5" in diameter. They drilled through so that they can put a piece of wire through to feel for studs! (apparently a stud finder didn't work)

There are some other smaller holes...they used a small drill bit...maybe 1/4" diameter.

My question is how do I patch those holes up? These holes don't have a surface on the other side. If I were to just fill it with something there's nothing on the other side for the filler to hold on to, right?

What should I do this fix?

Can I just fill the hole with stucco patching compound? (Something like Quikrete Pre-Mixed Stucco Patch?)

UPDATE: I can access some holes from the attic. Is there something that I can do from the back side of the hole from the attic? Should I screw in a metal mesh on the back side in the attic and then go to the outside and fill the whole with stucco patching compound?

The best way is to knock out enough stucco to find the studs, mount a backing plate to the studs, and stucco over that.

Now, that's a lot of work, so there are quicker& easier ways. Perhaps you could cut a small plug out of plywood or similar material which press-fits each hole, then do a skim-coat over it to match the stucco.

It comes down to time vs. quality, basically.

That does seem like a lot of work for a 1.5" hole. Aren't studs 16" apart? – milesmeow Jun 18 '16 at 06:51
@milesmeow Well, I *did* sayit would be a lot of work... – Carl Witthoft Jun 18 '16 at 11:35
Interesting idea to use a plug... – milesmeow Jun 19 '16 at 06:27
What about the small 1/4" holes? Just fill it right? – milesmeow Jun 24 '16 at 16:22
