There are many techniques and products available for controlling aphids. We present those solutions in three groups, do-it-yourself solutions using no insecticides, using natural insecticides and using synthetic insecticides. All solutions presented are considered safe by our authors for use in the home landscape. There are some products on the market that we do not recommend because so many effective options exist that are less toxic to the environment.
