Despite your best efforts, these voracious vermin are tenacious. Aphids can potentially be avoided by cleaning the garden and flower beds in the fall, preventing bugs and eggs from wintering and even introduced predatory bugs to eliminate the remnant. Finally, you applied the appropriate pesticides and still there are little green intruders mucking about in your garden.
But, have no fear, because even at this advanced stage, there are methods of controlling this problem.
Spot Them Early
The early response is always going to require less effort and be more effective, so make sure you are checking the undersides of your shoots and shrubs from very early in the spring. Wait till after the weather gets warm and you could be yanking aphids from your plants by the fist full.
Look at the Age of the Plant
You will come to notice that you mature shrubs and older rose bushes will be more resilient to the aphids attack than your tender tomato shoots younger plants. If you have younger plants in your garden your will need to spring into action to defend them from the juice-sucking vampires. Older plants should be protected as well, but their age and immunity makes them resilient to aphid attack.
Give Them a Cold Shower
By far my favorite way to disperse these vermin. I like to vent my wrath on these little beasts when watering my garden. If I see them paying special attention to a specific plant I will scatter their crowded societies with a flood of high pressure water. I defend my garden with high pressure water attacks.
Add a Little Flour
If water is not effective at convincing them to move, you can clobber them with a flour attack. For larger infestations this is one of the most effective maneuvers. The application is exactly as you would imagine, sprinkle generous amounts of flour all across the aphid presence and sit back and watch them suffocate. This is an inexpensive and effective way of treating a large infestation. As you go watering and flouring the aphid presence will diminish.
Oils and Soaps Can Help
If you are so inclined, there are some other options that offer a more direct attack to the insect invasion. Consider any of these options.

A Little Dishwater
Maybe the cold water treatment didn’t work, may be the plants were too tender for high-pressure water. No problem, fall back to the kitchen where a more potent plan to hinder aphid activities can be devised. In a conventional spray bottle, mix water and dish soap to a soapy solution. This is 100% safe for the plants and the fruits you may plan on eating, but it will not be popular with the aphids and they will flee before you.
This is another option for reducing aphids in your garden. This should only be used as a last resort and you should read the uses and instructions carefully before attempting it. DE can also kill honeybees and should never be used on flowering plants.
