Large bindweed · Calystegia silvatica

Why are there bugs on my Large bindweed?

Large bindweed is a magnet for aphids, especially when it is growing quickly in the spring. These tiny insects cluster on new stems and leaves to feed on sap. Check the undersides of your leaves first to confirm they are the culprits.

Check these first

  1. Inspect the undersides of new leaves for clusters of tiny insects.
  2. Check for sticky honeydew on the stems.
  3. Look for fine webbing near the leaf joints.

Likely causes

  1. Aphid infestation

    Most likely

    How to tell: You will see small green or black insects clustered on the tender new growth. They often leave behind a sticky residue called honeydew.

    What to do: Spray the plant with a strong stream of water to knock them off. If they persist, apply insecticidal soap or neem oil every 5 to 7 days until they are gone.

  2. Spider mites

    Possible

    How to tell: Look for fine webbing between the leaves and tiny yellow stippling on the foliage. These pests thrive in dry and dusty conditions.

    What to do: Increase the humidity around your plant and wipe the leaves with a damp cloth. Use a miticide if the infestation covers more than a few leaves.

Questions people ask

Can I just use dish soap?
A very diluted mixture of mild dish soap can work, but commercial insecticidal soap is safer for the plant. Avoid using soaps with degreasers or heavy fragrances.
Will these bugs kill my bindweed?
Large bindweed is very resilient and rarely dies from aphids alone. However, they can stunt growth if left unchecked for a long time.
