Tuberous begonias are beautiful plants that produce stunning blooms during the summer months. However, like any other plant, they are susceptible to pests and diseases that can damage them. In this article, we will discuss the most common tuberous begonias plant pests, how to identify them, and the best ways to treat them.
Aphids are small, soft-bodied insects that suck the sap from the leaves and stems of tuberous begonias. They are usually found on the undersides of leaves and can cause the leaves to curl and distort. Signs of an aphid infestation include distorted leaves, sticky honeydew residue, and the presence of ants.
Treatment: The best way to treat aphids is to spray the plant with a strong jet of water to knock them off. You can also use insecticidal soap or neem oil to kill them.
Spider mites are tiny arachnids that feed on the sap of plants. They are usually found on the undersides of leaves and cause yellowing and browning of the leaves. Signs of a spider mite infestation include webbing on the underside of leaves, yellowing or browning of leaves, and stunted growth.
Treatment: The best way to treat spider mites is to use a miticide spray. You can also try spraying the plant with a strong jet of water or using insecticidal soap.
Mealybugs are small, soft-bodied insects that produce a white, powdery substance on the leaves and stems of tuberous begonias. They suck sap from the plant, causing it to weaken and die back. Signs of a mealybug infestation include white, cotton-like substance on the plant, yellowing leaves, and stunted growth.
Treatment: The best way to treat mealybugs is to use insecticidal soap or neem oil. You can also try wiping the plant with a cotton swab dipped in rubbing alcohol.
Thrips are small, slender insects that feed on the sap of plants. They are usually found on the leaves and flowers of tuberous begonias and cause them to become distorted and discolored.

Treatment: The best way to treat thrips is to use insecticidal soap or neem oil. You can also try spraying the plant with a strong jet of water.
Scale insects are small, oval-shaped insects that attach themselves to the stems and leaves of tuberous begonias. They suck sap from the plant, causing it to weaken and die back. Signs of a scale infestation include small, round, brown or black bumps on the plant.
