Defending Your Cacti: Tips to Tackle Common Cactus Pests

Cacti, with their unique shapes and resilience, add a touch of desert charm to any indoor or outdoor space. However, just like any other plant, they can fall victim to pesky pests. Dealing with these critters can be a prickly situation, but fear not! You can keep your cacti healthy and thriving with the right knowledge and approach. Let’s dive into some common cactus pests and how to deal with them.

Common Cactus Pests


These tiny, cotton-like insects can quickly infest your cactus, sucking out plant juices and causing damage. Keep an eye out for white, fuzzy patches on your cactus, especially in the joints and crevices. To tackle mealybugs, gently wipe them off with a cotton swab dipped in rubbing alcohol. For severe infestations, consider using insecticidal soap or neem oil.

Spider Mites

These minuscule pests are notorious for spinning webs on cacti and sucking the sap from their tissues. If you notice fine webbing or specks moving on your cactus, you may have a spider mite problem. To combat them, regularly spray your cactus with a strong jet of water to dislodge the mites. Additionally, introducing predatory mites or applying insecticidal soap can help keep their population in check.

Scale Insects

Scale insects appear as small, waxy bumps on the surface of cacti, resembling scales. They feed on plant sap and can cause wilting and yellowing of the cactus. To remove scale insects, gently scrape them off with a soft brush or cloth. Follow up with a neem oil solution to prevent their return.

Fungus Gnats

These tiny flying insects are attracted to moist soil and can lay their eggs in cactus pots. While adult fungus gnats are more of a nuisance than a threat, their larvae can feed on cactus roots, leading to root damage. To deter fungus gnats, allow the soil to dry out between waterings and avoid overwatering your cactus. You can also use sticky traps to catch adult gnats and prevent them from laying eggs.

Root Mealybugs

Unlike their above-ground counterparts, root mealybugs reside in the soil and feed on cactus roots, causing stunted growth and yellowing of the plant. To tackle root mealybugs, carefully remove the affected cactus from its pot and inspect the roots for signs of infestation. Trim away any damaged roots and repot the cactus in fresh, well-draining soil. Consider treating the roots with a systemic insecticide to eliminate any remaining pests.

Prevention is key when it comes to dealing with cactus pests.
