THE SHORT ANSWER
Inspect soft new growth and leaf undersides. If aphids are confirmed and damage is limited, monitoring or a careful stream of water may be enough. Preserve beneficial insects and use any pesticide only as labeled for the exact edible crop.
Confirm what you are seeing
Aphids are small, soft-bodied insects often found in groups. Curled growth, sticky honeydew, and shed skins can draw attention to them, but those signs alone are not a complete identification. Look closely and use an extension identification guide.
Photograph the insects at a useful scale and note the host plant. A phone’s close-focus mode may help, but a sharp photo of the whole affected shoot is often more useful than an extremely enlarged blur.
Check the size of the problem
Look at more than one leaf. Is the colony confined to a few tender tips, or widespread? Are you seeing lady beetles, lacewing larvae, or other natural enemies? Some aphid populations decline without a pesticide application.
Mark one affected shoot with a loose tie and take a reference photo. Inspect it again over the following days. This gives you a comparison instead of relying on the feeling that there are “more bugs everywhere” each time you look.
Start with a targeted response
On a sturdy plant, a controlled stream of water can dislodge aphids. Support delicate stems and avoid blasting a young seedling or flooding a small pot. Heavily infested individual tips may sometimes be removed if the plant can spare them.
Inspect nearby containers and new plants before placing them together. Keep your response proportional to actual damage. The objective is a usable, healthy crop, not an outdoor plant with no insects of any kind.
Use labeled products carefully if needed
If further treatment is warranted, identify a product labeled for both the crop and pest. Follow application instructions, weather restrictions, and harvest intervals. Household detergent mixtures are not equivalent to formulated insecticidal soap and can damage plants.
Record what you used, where, and when. Check the result according to the label instead of repeatedly applying a product without evaluating it. If identification remains uncertain or the plant deteriorates, ask local extension before escalating treatment.
