Aphids on a strawberry plant.

I woke up this morning to find aphids on my strawberries. There was a cluster of them dead on the fuzzy parts, but the daisies next to them were still infected with live aphids. What should I do?

Artur, Director of Operations at Winterbourne Farms: Good guys like hoverfly or ladybug larvae are probably eating the aphids on the strawberries.

I would wait a few days to see if natural predators take care of the aphids on the daisies, too. If the problem persists, go with an organic solution like an insecticidal soap.

Spray thoroughly at dusk after the bees are asleep and again two days later.

Hoverflies are natural predators of aphids.

Natural insecticidal soap recipe

  • Mix together 1 tsp of castile soap with 1 quart of warm water. Dr. Bronner’s Peppermint Pure-Castile Liquid Soap is a favorite.
  • Fill a clean spray bottle with the mixture and shake.
  • Add ½ tsp cayenne pepper or cinnamon, if desired.
  • Spray directly on aphids, but take care not to burn the leaves of the plant. You can wash the soap off a few hours later.
