Put it all in a spray bottle, mix it up (foaminess is good), spray every day 'til the aphids kick the bucket!
Also, I use the high-powered spray from the hose to knock them off if the roses are still in bud stage.
Or, as a last resort, I put on my garden gloves, crush the little buggers with my fingers (yuk!), then top the roses off with the homemade spray.

I was picking coddling moths worms off my apple tree leaves and discovered a few aphids on the new growth tips. However just as I was getting finished and wondering about the aphids, I spied a healthy
Try this recipe for getting rid of aphids:
Combine these ingredients into a blender or food processor on high. Strain the pulp from the liquid using cheesecloth, a nylon stocking or a fine-meshed colander. Pour the remaining liquid into a spray bottle and spray it directly on flowers or plants to control aphids. Another easy method is to use a strong spray from a garden hose every few days until the aphids are no longer visible.
I spray infected plants with citric acid solution (1 teaspoon of citric acid dissolved in 0.5 L of water). I sometimes spray this solution on all plants as a protective method even if they're not affected, and repeat as needed, it works.

I have seen posts that suggest using vinegar to get rid of aphids. Isn't vinegar harmful to growing things?
Vinegar is a great HERBICIDE (weed killer). For aphids, I suggest a squirt of liquid dish soap in a pint or so of water, spray the leaves, contacting as many aphids as possible.
I am looking for a recipe for killing aphids with dish soap and water.

get a large spray bottle big enough to hold the followig ingredients:
1 cup vegetable oil or white mineral oil
2 cups water
2 teaspoons bleach free dish soap
Add all ingredients to spray bottle and shake well before each use because the oil separates from the soap mixture once it sits for a bit. When spraying your plants, bushes etc... be sure you spray under the leaves and on any new growth as that is where the aphids love to hide and eat. This works excellent for us and I hope it will do the same for you. Be sure not to add more soap than required as it can kill your plants.

Will liquid a hand soap dissolved in water kill aphids?
I used dish soap and water on my garden all last summer with great success. The inexpensive store brand worked the best. Start with a few drops per 32 oz spray bottle, every other day for a few days. Then keep increasing the soap ratio as the plants get used to it. The bugs and slugs hate it but the bees seem to still work around it. Make sure you get the soil too because that's where they lay their eggs. Dish soap acts like a fertilizer for the soil too. I sprayed before dark and it worked great. Good luck!

It's true. When sprayed on aphids, a solution consisting of liquid dish soap and water will kill aphids and many other soft-bodied insects such as caterpillars, thrips, mealybugs, spidermites, leafhopper, lace bugs, and whiteflys. Most of these soaps are made from the potassium salts of fatty acids. When sprayed on soft-bodied insects, these fatty acids disrupt the structure and permeability of the insects' cells, causing the contents to leak out, which quickly kills them. Most any type of liquid dish soap will work, but DAWN is biodegradable and contains no phosphates, which is better for the environment.
Insecticidal soaps only work on contact and not as a preventative measure. In other words, the soap needs to completely cover the body of the pest you're trying to control. Dried soap residue on the plants will not harm the insects. The disadvantage to using insecticidal soaps is that it causes phytotoxicity (damage from chemicals) in some plants. Here are some tips for using insecticidal soaps effectively:
We have aphids on some of our plants. I have heard that dish soap in water will control them. Does anyone know the amount of dish soap to use?
two tbls dishsoap (Dawn or good quality)
one tbl white vinegar
one tbl vegetable oil
one tbl baking soda
Mix into one gallon water...then put in spray bottle.
This is really great for roses...apply every seven days. (05/02/2005)
They seem to be early here this year. I took some my foaming soft soap dispenser out and squirted them and let the foam sit. It seemed to do the trick. This wouldn't be practical for anything but a small infestation.

Put enough Palmolive Green Liquid Soap in some tepid water to get good bubbles. Then pour it on the plant and be sure to pour bubbles and all on the dirt the plant is in. You want it sudsy enough to wash a butter-coated pan. (05/03/2005)
