Info / Symptoms:

Aphids are one of the most destructive pests for plant life. They cause damage to many different types of plants by sucking the sap of the plant as well as transmitting viruses from plant to plant. Aphids can have many effects on plants, especially those in temperate regions or indoors. Because female aphids breed heavily, infestations can occur at a rapid pace.

If your plant begins to show signs of distress, check the tops and bottoms of the leaves for very small insects. Aphids can be various colors (red, green, black, yellow and white are most common) depending upon their type and what they are feeding on. They can be almost microscopic, so make sure to look over the plant thoroughly. 

Control Methods:

Treating aphids can sometimes be tricky since they have become resistant to many different insecticides. Contact insecticides can be applied if the aphids are visible or if all of the leaves can be sprayed thoroughly. Organic solutions include higher pressure water on the leaves as well as soapy water. Insecticidal soaps will provide some control.

Bonide Eight™
Garden and Home Insect Control and Bonide Systemic Houseplant Insect Control are the insecticides that we recommend using for the treatment of Aphids. It is available in a ready to spray (attach to the hose) container. See chart below for timing and frequency recommendations. 

Application #1 – Eight™ Garden and Home Insect Control Application #2 – Eight™ Garden and Home Insect Control
Take the plant outside (if not already) and coat all leaves thoroughly. Spray directly on Aphids if possible. 5-7 days after initial application

Application #1 – Bonide Systemic Houseplant Insect Control
Apply it at the base of the plant and water it in. Allow up to 4 weeks for plant to take up insecticide
