Insects make their way into your houseplant's soil during the summer and survive during the winter by living in the plant's soil and feeding on the leaves. Chemical insecticides eliminate adult insects but can negatively affect the houseplant's health. Improper use causes the plant to absorb the chemicals through the soil. Natural, homemade insecticides eliminate adult insects while protecting the plant's from unnecessary damage. Nonchemical insecticides are suitable for light infestations but ineffective if the houseplant is heavily infested with insects.
