Remove the aphids by hand (wearing gloves) or using a sharp stream of water. Cut away and dispose of infested foliage. Capture flying aphids by placing yellow sticky traps near infected plants. Make a nontoxic pesticide by mixing 1 c. vegetable oil with 1 tbsp. liquid dishwashing soap. Add 1 1/2 tsp. solution per cup of warm water to a handheld spray bottle. Hit the aphids directly with above mixture and spray entire plant thoroughly.

Rid your garden of ants. Ants love to eat "honeydew," the sugary sap secreted by aphids, and will keep the aphids alive by fending off predators and carrying the sap makers to other plants.
