CHECKS
If you see sticky leaves but cannot find matching insects: Keep the cause open. Inspect young shoots and leaf undersides with a magnifier and take a close photograph before choosing an aphid response.

If a small matching colony is present and growth is continuing: Look for lady beetles, lacewing larvae or swollen aphid mummies before intervening. Choose another inspection if natural enemies are active and the plant is coping.

If matching colonies are building on accessible new growth: Rub or brush the insects off, or dislodge them with plain water as described by UMD. Support the tender shoot and use a manageable stream; stop if it bends or tears the plant.

ACTION CHECKLIST
[ ] 1. Select one shoot to compare
Photograph its top and underside. Count the occupied leaves, note whether growth is distorted and record any natural enemies without assuming every insect is a pest.

[ ] 2. Choose monitoring or physical removal
Write the observation behind your choice. If removing insects, work on the occupied surfaces with fingers, a gentle brush or plain water rather than spraying the entire pot with a home mixture.

[ ] 3. Check immediately after the action
Inspect the same surfaces for insects left behind and any handling damage. Record the leaves cleared and those you could not reach; stop handling a fragile shoot.

NEXT CHECK
Recheck the marked shoot and neighboring new leaves at the next visit. Compare occupied leaves and new growth, not just old sticky residue. Seek local identification if insects do not match or the plant keeps declining.
