Is neem oil detrimental to pollinators ?
Neem oil's properties are targeted to chewing insects so bees and butterflies are deemed safe.
It's also best to spray any pesticide during the late evening or early morning, when pollinators are not foraging.

I am using apple cider vinegar & dish soap, it is located in a terrarium. I am using it to kill fruit flies that come in my apt. Will it hurt my houseplants to add it to the distilled water, when I water the plants?
Vinegar can kill your plants so don't add it to their water. The apple cider vinegar, plus a little sugar and dish soap in a small container will attract and kill the fruit flies. Place it near water such as a sink.
Are you sure they are fruit flies and not fungus gnats? Fungus gnats hatch out of moist soil so keeping your houseplants on the drier side helps with those. Sticky traps can also help.

We don't recommend specific places for purchase, but I can recommend searching online. Many places offer it, and will ship it to you! You can, even, find it locally using search.

I have a hedge along my driveway, I’m not sure what kind of plant it is (just moved in recently) and the leaves are looking rather unwell and there is a white powder on many of the leaves. Can somebody tell me what’s kind of plant it is, what is wrong with them and what to do about it?
I can't quite tell what the shrub is in that condition, but I can tell you that those are blister mites and their damage. Here are some articles that will help:
