Thrip are tiny winged brown insects that feed on the surfaces of plant leaves, flowers, and buds. They leave silver spots around their feeding areas and dark dots of excrement. Thrip not only weaken plant growth and distort buds and flowers, they transmit viruses from plant to plant as they fly around. The green solutionIf you don't want to use a commercial chemical product to treat plant pest problems try the “Green Solution.” This is a mixture of water, alcohol, biodegradable liquid soap, and mineral oil. Always test any spray on one or two leaves to be sure it won’t damage the plant. Depending upon how severe the infestation is, you can use these ingredients in varying proportions. If there are only a few pests, dip a Q-tip in alcohol and gently swab them off. For a more widespread problem, start by using a spray of warm water mixed with a few tablespoons of biodegradable soap. If that doesn’t cure the problem, make a solution using 8oz. water & 8oz. alcohol, add two tablespoons of biodegradable soap and two tablespoons of mineral oil. Spray all areas of the plant. Use this solution on leathery leafed plants (except palms), never on fuzzy leafed plants like African Violets or Begonias. For palms, omit the alcohol from the Green Solution. Never spray a plant that’s sitting in the sun or one with very dry soil. , Neem OilLearn about Neem Oil, a natural, organic, non-toxic product for treating houseplant insects and diseases., and yellow sticky cardsThis small dark skinny pest flies and jumps around plants and people driving us all crazy.
