Common Pests

Spider Mites

Spider Mites

What To Look For: Very fine webbing under leaves or between stems and leaves (especially in dry indoor air). Leaves may appear stippled (tiny yellow or white dots) or dusty; they may turn yellow, brown or drop. When you tap a leaf onto white paper, you might see tiny moving specks. (Often too small to see easily)

How To Treat: Increase humidity around the plant (since mites thrive in dry air). Spray plant thoroughly (both sides of leaves) with insecticidal soap or a miticide/plant-safe oil; repeat every few days. In heavy infestations, consider removing severely affected sections; isolate the plant.

Mealybugs

Mealybugs

What To Look For: White, cottony or waxy masses on stems, leaf axils, underside of leaves. Sticky honeydew, sooty mold growth, yellowing or dropping leaves.

How To Treat: Use a cotton swab dipped in rubbing alcohol to dab and remove visible bugs. Wash leaves and stems with gentle soapy water. In heavy infestations, consider removing very affected stems/leaves or, in the worst case, replacing the plant.

Scale Insects

Scale Insects

What To Look For: Small oval or round bumps on stems or leaves; they may look like part of the plant. Sticky residue/honeydew, sooty mold. Yellowing leaves, leaf drop, and decline in plant vigour.

How To Treat: Physically scrape or wipe off scale insects when you see them; use your fingernail or a soft brush. Use horticultural/plant-safe oils or insecticidal soap when the crawler stage is active. Re-inspect regularly because scale eggs and crawlers can hide under shells.

Thrips

Thrips

What To Look For: Tiny, slender insects are often difficult to see; damage appears as silvery or grey stippling on leaves, distorted growth, or black specks (their feces). May also see uneven colouring, leaf silvering, and leaf edges curling.

How To Treat: Use insecticidal soap, making sure to cover all surfaces, including undersides, and new growth. Trim off and discard severely infested growth. Monitor with sticky traps (blue or white) and isolate the plant.

Aphids

Aphids

What To Look For: Small soft-bodied insects (green, yellow, black or orange) usually congregating on new growth, stems or leaf undersides. Sticky residue (“honeydew”) on leaves or nearby surfaces, sometimes with sooty mold developing on it. Distorted or curling leaves, wilting, slow growth.

How To Treat: Isolate the infested plant to prevent spread. Blast with water to dislodge many adults, especially on newer growth. Use insecticidal soap, making sure to cover the leaf underside and new growth. Repeat treatments every 7 days or so until no new signs appear. (Since they reproduce quickly)
