I've had this cacti for about a year. All these plants pictured was originally in one pot, but I separated them and planted them in several containers. As it has been winter and I have to keep these cacti away from other plants, it's in a corner of my living room that doesn't get much light. Despite the lack of adequate light, it has new growth... it also has fluffy white tufts on the base of the spindles... I tried treating it with rubbing alcohol to no avail... it's difficult to do such because of the size of its needles, especially when it was all in one pot... Is it infected with mealy bugs or something else? What would be the best approach to eradicating them or saving these prickly cacti?

Welcome!

Your cactus is Austrocylindropuntia subulata – Eve's Needle Cactus. Usually, this cactus forms a huge colony of really pokey cactus (probably what it looked like before you divided it).

It doesn't have mealy bugs - that's what they look like. Your's need a lot more sunshine though.

These cacti do grow fine hairs at the base of the spines, they are not super dense in my plant, but as far as I can tell from your pictures, what you are talking about are just abundant expressions of those fine hairs. I do not think that is an indication of anything wrong with your plant, it just wants more light, but it sounds like you are already aware of that.

Thanks!!! I was so worried that there was something wrong with it that I separated it from my other plants that are in adequate lighting. The white tufts weren't pronounced like they are now when I purchased my Eves needle and Google photos of it didn't show thick, white growths at the base of the spindles. Now that I know that it's normal, I'll re-pot it together again (looked much better that way) and make sure it has adequate lighting. Do these go dormant during the winter? I'm thinking maybe not due to the new growth on it.

Now rhat you have repotted it, I wouldn't repot again. Those pots of singles will quickly turn into doubles and triples.
