In many cases cactus plants that are infested with insects like mealy bugs are very hard to save whether using insecticides or 'green' alternatives. The choices we make about how we deal with insect problems may be as much a matter of our own health as it is saving the life of the plant.he way to get this witch hazel to kill insects like mealy bugs is to take the plants out of their soil and dip the plants in witch hazel for a while. The witch hazel needs to be rinsed off of the cacti with water, then allow the plants to dry and replant them in new soil.
