I'm struggling with an aphid infestation, but there are no ladybugs around to help me out. What are some effective methods I can use to get rid of these pests?

I usually just mix a gentle soap and water solution, spraying it directly on the aphids. It works really quickly! You don’t need much soap—about a teaspoon of dish soap to a gallon of water is enough. Just reapply every couple of days and you'll be set.
One effective method is to blast the undersides of your leaves with a strong jet of water early in the morning. This knocks a good number of aphids off, making it harder for them to get back on. After rinsing, you should coat all leaf surfaces, especially the undersides, with insecticidal soap—mix about a teaspoon of mild liquid castile soap in a quart of water. Try to do this when it's not too sunny, and rinse it off a few hours later to prevent leaf burning. You might need to repeat this every 3-5 days to tackle any hatchlings. If ladybugs aren’t available, consider introducing other natural predators like green lacewing larvae or hoverflies, which you can attract by planting herbs like dill or cilantro. And don’t forget to keep ants away, as they farm aphids for honeydew! Interplanting with garlic or chives can also help deter them. Good luck with your garden!
Thanks so much! I found them on my bell pepper plants just now, even the one planted on four sides with marigolds. I guess they don’t bother the aphids that much.

Question: is the leaf burn from the sun hitting the soapy water? If I spray it late in the evening does it still need to be wiped off?
