Likely causes
Cherry Fruit Fly
Most likelyHow to tell: You might notice tiny pinprick holes on the fruit surface. Inside, the fruit will be soft and contain small white larvae.
What to do: Hang yellow sticky traps in the tree canopy in late spring to catch adults. Use an organic spinosad spray once the fruit begins to change color to protect the crop.
Aphids
PossibleHow to tell: Leaves will look curled or sticky with a shiny substance called honeydew. Look for clusters of tiny green or black bugs on new growth.
What to do: Spray the leaves with a strong stream of water to knock them off. If the infestation is heavy, apply neem oil or insecticidal soap.

When to worry
If you find larvae inside your cherries, the fruit is not edible. Aphids are usually a minor nuisance unless they are causing severe leaf curling.
Stopping it coming back
Keep the ground under your tree clear of fallen fruit to stop the life cycle of fruit flies. Encourage beneficial insects like ladybugs to visit your garden.
