How to Get Rid of Aphids

Aphid infestation in your garden is one of the most frustrating things you can experience. If left unattended, they can destroy your garden plants, including vegetables, flowers, and fruit trees. Aphids destroy your plants by sucking the plant sap. This may cause twisting, rolling, or bending leaves, leading to yellowing and wilting of the same leaves. 

Besides sucking the sap, aphids feed on flower buds and fruits, which leads to the malformation of flowers and fruits. While feeding on your plant nutrients, aphids excrete honeydew, a sticky substance that attracts the growth of sooty mold fungus. High infestation of aphids on your plants can lead to stunted growth and their spreading to other plants in your garden.

If your plants receive little care, eradicating aphids can be a lengthy process. You should conduct regular inspections of your plants for early detection of aphids. Aphids are quick to multiply, do not wait for them to multiply to start treating them.
