What's the fastest method to eliminate aphids?

Using water spray will be the most rapid method of aphid removal. Use a hose with a water pressure of 40-60 PSI. Spray the underside of leaves in the early morning when the aphids are slowest. The water will knock the pests off the plant immediately, causing little to no damage to the plant. Use this method in conjunction with manual removal of aphids for optimal aphid control.

The best time to maximize your efforts is early in the morning. At temperatures lower than 65°F (18°C), aphids don't move as fast. The overnight experience weakens their handhold. When aphids are involved, I always begin treatment at sunrise. By that time, I can remove aphids before they become active. The cool temperature also slows their escape.

To accomplish the best possible outcome, I employ a combination of methods. Spraying water instantly removes surface aphids, while manually removing them retains those hiding in the crevices. An old toothbrush works quite well for tight spaces. The soap solution makes sure that the survivors do not return. This combination resolves an infestation in hours, not days.

Prevent fast reinfestation post-treatment. I try to apply neem oil within 24 hours. It will stay in the environment to provide residual protection. I also introduced ladybugs to the site the same day, as they will consume stragglers. I continue this practice for three days to completely break the breeding cycle.
