All bear numerous young, and spread rapidly by crawling or being transported by wind and ants. Some female aphids even bear live young, which in quick turn bear more live young and so on. The ants spread the aphids because they feed off the sweet exudates called honeydew, which drips from the aphids' abdomens. There are many compounds that are effective against aphids. They include citrus-peel extract, fungi, garlic, growth regulators, horticultural oils, insecticidal soaps, neem, and pyrethrum.
Many insects also feed on aphids.
Ladybugs are probably the most easily located. Praying mantis are commercially available but will starve or fly away if the food source disappears. For one cyclamen plant, I would suggest you try spraying the aphids every day for 10 days with an insecticidal soap. Mix the soap according to the directions on the package. Spray the plant thoroughly on both sides of the leaves.
