A strong spray from a hose will knock aphids and other insects to the ground where they often become someone else’s dinner. Spraying with pesticides should always be the last resort – and done with great caution because they will kill many beneficial insects and are harmful to other animals (including humans). Remember that over 90% of all insects are beneficial or benign so don’t pull out the toxic spray at the first sight of bugs. Are they doing any damage or are they just scary to look at? Can you live with the amount of damage they are doing — a few holes in leaves? Have you tried that jet of water or a nontoxic spray? Learning to live with the other creatures in the garden that are doing little or no harm is an important step for everyone.
