How to Get Rid of Aphids in the Garden?
Aphids are insects with soft bodies that cover the leaves and stems of your plants and suck the sap out of your garden plant. They range from shades of green to grey or reddish brown color. Luckily, these are easy to spot and easy to get rid off.
What are Aphids?
Aphids easily venture into indoor and outdoor gardens. They are small, soft-bodied insects that multiply quickly, thus you need to control them before they start reproducing. Female aphids do not need mating to reproduce. They excrete a living female offspring between 3-100 times daily.
Aphids are very tiny, and often invisible to the naked eye. A 10x magnifier can be used to spot aphids on your plant. They range in colour from white, black, brown, gray, yellow, light green, to pink! Some have a waxy or woolly coating, pear-shaped bodies with elongated antennae; the nymphs look similar to adults. Most species have two chronicles projecting from their hind.
Mostly adults are wingless, but some species can develop wings when overpopulated and travel to other plants. Aphids usually feed in groups.
Aphids feed on a wide variety of plants, but some species can be specific to particular plants. For example, bean aphids, cabbage aphids, potato aphids, green peach aphids, and melon aphids.
Aphids pierce the stems of plants – preferring succulent new growth – to suck out the nutrient-rich sap, thus weakening the plant and causing it to die. Aphids carry lethal viruses which infect a host plant as they feed. These viruses can easily damage potatoes, citrus fruits, and grains. Furthermore, the honeydew secreted by aphids creates an environment for sooty moulds which spread quickly to coat the plant leaves and deprive it of sunlight.
- To find aphid infestation look for symptoms like curling, stunted, or yellow leaves. Check the undersides of leaves, as aphids love to hide. Read about why your plants are turning yellow.

- The honeydew can develop a fungal growth known as sooty mould, causing both branches and leaves to appear black.
