One of the most common household pests that can infest your plants is the aphid. Commonly known as plant lice, they are found on the underside of new growths in a plant. They drain the fluids that a plant needs to grow and thus stunt its growth. They are generally small and come in a variety of colors. A person growing house plants should know how to kill them.
How to kill aphids
Take a spray bottle, fill about three-fourths of the bottle with water and the rest with equal amounts of soap and commercial dish detergent.
Separate the plant from all other noninfested plants.
Spray the plant thoroughly with the mixture you prepared in the spray bottle. Let it dry for some time.
After a few minutes, spray the plant again thoroughly.
Remove any aphids you can see with a dry cloth. Keep the plant isolated from all the others for about a week. Repeat steps one through five again.
