Plant pest clues: what to photograph and check

Sticky leaves, fine webbing, tiny moving dots, pale speckles, or distorted new growth can justify a closer look. They do not all point to the same cause, so start by recording the location and pattern instead of treating the plant from one mark.

Take a full-plant photo first

Keep the pot, neighboring leaves, and plant shape in the frame. Then take close views of the top and underside of an affected leaf. A clear sequence is more useful than one heavily cropped image.

Inspect predictable hiding places

Look under leaves, along veins, where leaves meet stems, and around new growth. Use strong indirect light and your phone camera for magnification. Record webbing, sticky residue, raised bumps, shed material, holes, or distorted tissue without assuming the name of the cause.

Compare affected and unaffected areas

Check whether the clues appear on one leaf, one side of the plant, new growth, or several nearby plants. A spreading pattern changes the urgency and helps a local expert understand what you are seeing.

Review recent introductions

Note new plants, cut flowers, outdoor time, open windows, repotting, or changes in humidity. Context can be as important as the visible mark. Keep newly introduced plants separate when practical while you observe them.

Choose treatment only after the check

Different pests and non-pest damage can look similar in a photo. Avoid mixing several treatments or using a product without following its label. For a severe or spreading issue, use a qualified local nursery, extension service, or plant professional.
