Although they're small in size, aphids can cause substantial damage to houseplants, which may be irreparable if left untreated. The tiny insect which feeds on a plant's sap can be controlled though, using either natural means or commercial products. Take guard and action quickly to rid this common pest from your indoor plants.
How to Get Rid of Aphids on Indoor Plants
Wash the bugs away. Take the infected plant outside, and hose it down with a stream of water. Carefully wash both sides of the leaves. Look closely under leaves as aphids tend to feed on the underbelly. Wipe the bugs away with your fingers or a cotton swab if the infestation is light.
Use a special insecticidal soap to wash the critters away. Such soaps are readily available in gardening stores or can be easily made at home. Make your own insecticidal soap by combining dish soap (not detergent), such as Ivory, with water. Mix 1 teaspoon of soap to every gallon of water.
Let nature take Its course. Ladybugs and green lacewings are natural deterrents to aphids. Introduce the beneficial bugs to infected plants. Remove the ladybugs from the infected plant, and replace it in its natural outdoor habitat once the infestation is gone.
Use the buddy system. Plant garlic cloves (just one or two), among plants that aphids are attracted to, according to English Gardening. An infusion of garlic crushed into water and sprayed on the aphids will also help remove them. Many herbs, such as hyssop, sage, dill, lavender and thyme discourage aphids if planted near to susceptible plants.
