How to Kill Pests on Aeonium Succulents

Aeonium succulents (Aeonium spp.) are stunning evergreen plants with a distinctive rosette form. They grow outdoors in U.S. Department of Agriculture plant hardiness zones 9 through 11 or indoors as houseplants. Despite having no serious pests or problems, aeonium plants are no stranger to soft-bodied garden pests that feed on the sap inside the succulent foliage. These pests are more of an annoyance than serious threat to aeonium succulents and can be controlled using various methods. The first line of defense is to spray the plant with a water hose to dislodge aphids, spider mites and other soft-bodied pests. If that doesn't work, try a spray.

Instructions

  1. Homemade Control Method

    • 1

      Mix 2 tablespoons of cooking oil and 2 tablespoons of baby shampoo in 1 gallon of water. Pour the mixture in a garden sprayer or hand sprayer.

    • 2

      Spray the homemade bug spray on a small, inconspicuous area of the plant and wait for two to three days. If you see no damage, it's safe to spray the rest of the plant.

    • 3

      Coat the aeonium -- including the undersides of the leaves and the central rosette -- thoroughly with the homemade insect spray. Reapply the treatment every five to seven days, if needed, with fresh solution.

    Chemical Control

    • 4

      Pour 1 gallon of soft water in a 5-gallon bucket. Add 2 1/2 fluid ounces of insecticidal soap and stir for several seconds until the water and soap are well mixed.

    • 5

      Fill a garden sprayer or hand sprayer with the diluted insecticidal soap. Spray the entire aeonium -- including the undersides of the leaves -- thoroughly with the solution to the point of runoff.

      Repeat the treatment with fresh solution every seven to 14 days, if needed, until the pests are no longer a problem.
