Aphids are tiny pest insects that most gardeners have had to address at one time or another. There are over 4,000 different aphid species and their color can range from green to white to black.
In addition to the damage they create by eating the sap from healthy plants, they excrete a sticky substance called honeydew. This honeydew attracts mold and ants, which do additional damage to the already-weakened plants.
The good news is, there are a number of natural, organic ways to prevent and treat aphid infestations.
