The ants are not a problem. They do not damage the bamboo...they are usually mining the sweet residue left by aphids. The "white type of mold" is probably secretions from mealy bugs. Hosing off your bamboo regularly should help keep things under control. If you want to use a soap spray like Safer or a solution of neem oil, that will help, too.

Finally, carpenter ants are highly unlikely to be interested in bamboo. (They also have a distinctive appearance that makes them easy to identify.)

Thank you very much for the advice. I do have one more question though. Today I noticed one of the leaves curled a little and checked under it. What I saw was a web sticking from each side of the leaf like a little canopy about an inch long. At first I thought "ah ha" mealy bug. But then I notice a spiders legs sticking out. I couldn't see the whole body so I'm still a little weary. The legs didn't look stringy like the pictures I saw of the noxious mealy bug. And the web may have seemed more sticky due to it being wet from the rain the past couple of days. If it's a spider it's beneficial, if not I'm just not sure. I couldn't really tell what that noxious type mealy bug looked like from the pictures I found on the internet. The red mealy bugs I can actually see what's what in the pictures. Again thank you for all the advice.

The spider may just be a coincidental visitor and not a concern. If you had bamboo mites, they are very tiny black spots about the size of a pepper flake, and have little white, cottony webs on the underside of the leaves. The damage they do is to eat chlorophyll from the leaves and the top sides of the leaves develop little splotchy, white patches like dashes ("Morris code"). It doesn't sound like you have this, though.
