I got a pot of mixed plants and succulents at a yard sale about a week ago for a buck! The lady was selling the pot because she said the plants were a lost cause. In order to keep the succulents alive the soil was too dry for the plant in the picture (not sure what it is). I decided today I would separate them so the succulents could be in cactus soil and these could have a chance a survival, and so I could water them without over watering the succulents.
When I uprooted them I noticed these white bugs. I'm assuming an aphid of some kind. They are even on my succulents and the decorative marbles on the top layer of the soil. Before, I have treated aphids on outdoor plants by mixing cayenne pepper, dish soap and water in a spray bottle and sprayed the plant leaves until they are dripping, and let dry. This has worked and I'm going to try this on the unidentified plant in my picture, but am worried about spraying that mix directly onto the leaf of the succulents.
I know succulents absorb and store nutrients differently than "leafy" plants and don't know how safe this is. Even the cactus food I have is a spray foam instead of a water mix or spray. I don't know the biology behind it. Can anyone help?
Are these in fact aphids? Can I treat my succulents in the same manner, or is there a better or safer solution I should try? Are these pests specific to indoor plants, and if so, would putting my succulents outdoors help? All of the succulents I have are "full sun" succulents and can withstand the sun and the heat, they're just so pretty and I happen to have a large window that provides them with plenty of sun.
In addition, my other succulents that did not come from the same pot are thriving and producing "babies" and my two bromeliads are also doing well, neither of which have the white bugs. Should they be treated too in order to prevent spread?
