Cacti are popular and resilient plants, but they can fall victim to various pests. Identifying these pests early is crucial for effective treatment and maintaining healthy cacti. This guide will help you recognize the most common cactus pests and suggest remedies to control them.
Common Cactus Pests
Mealybugs
Mealybugs appear as small, white, cottony masses on the cactus. They often cluster around joints and crevices. These pests feed on plant sap, weakening the cactus over time.
Scale Insects
Scale insects look like tiny, hard bumps on the cactus surface, usually brown or gray. They attach firmly to the plant and can cause yellowing and stunted growth.
Aphids
Aphids are small, soft-bodied insects that can be green, black, or other colors. They tend to gather on new growth and flower buds, sucking plant juices and spreading disease.
