Aphids – small, soft-bodied insects that are among the most destructive insect pests on cultivated plants, especially in temperate regions. They weaken the plant by sucking the sap off. It’s hard to identify them as they are small, under 1/4 inch, and often nearly invisible to the eye! Damage will look like curling, stunted, or yellow leaves, and you’ll find them typically on the underside of the leaf. Control & Prevention – Typically start with spraying a strong stream of water to get them off the leaves, but if you’re looking for an organic method to remove them, try Neem Family products such as Neem Oil, Bon-Neem, or EndALL.
