These I believe needs full sun for it to grow well and becomes stressed - with that release pheromones that attracts pests especially spider-mites and mealybugs. I understand the scale insect too get attracted to them however the sun & rain seemed to deter all of that on them.
Usually the pups are still connected with runners coming from the mother plant - however there are primary roots that had grown vigorously on the pup that can be easily removed, detach the pup with a clean scissors or sterile knife - make a clean cut from the runner. Do not be tempted to snap it from bare hands as you can damage the pup or the mother plant accidentally. Worse if the cutters are infected with fungus or bacteria and may be fatal to the plant.
There are some mentions about this particular one going dormant but I doubt does behave like that in a tropical region. Also I had not come across them in any abandoned roadside or in open areas - which I realized that this particular one is not the "wild" type which often propagated by the seedpod by birds or other vectors.
