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.
Like armored scales, mealybugs (Pseudococcidae) also deplete cactus plants of fluids. The small wingless gray insects have elongated, waxy bodies. They also cover plants in sticky waste called honeydew that attracts ants. Use bait for the ants and insecticidal soap and horticultural oil spray to eradicate mealybugs.hey chew through the flesh of plants, and females lay eggs in the cactus wounds. While adults feed on the surface, larvae bore into stems to feed inside of the plant. Entrance holes created by beetles turn black. The bugs cause severe damage.
