Aphids on a rose bud.

Having a rose, or other flowering plant, suddenly covered in aphids can be a a depressing sight. Fortunately, there are many ways to get rid of them and you may not have to use chemicals. This is a guide about getting rid of aphids.

Solutions: Getting Rid of Aphids

Tip: Natural Aphid Spray

Imagine my chagrin this year when for the first time ever I decided to try growing dill and woke up one morning wondering why the upper most tender portions of the plants, which were ready for harvest, were drooping heavily sideways. Upon closer inspection those portions were covered with aphids. Well, I certainly didn't want to use anything as a remedy that would be toxic so went to several internet sites to find a workable natural solution.

By the way, you will also want to check plants, both edible and ornamental, near the infested ones. I found those little buggers were also beginning to munch on my pepper plants! This is the solution that worked for me in just a couple of days by adjusting assorted homemade recipe ingredients that I came across on the web. First, in the case of my dill, I cut off the upper portions, which were most likely no longer fit to consume anyway, rinsed the remaining portions of the plants with a heavy stream of water and then heavily sprayed the plants and the surrounding soil with a water bottle using the following recipe:

Ingredients:

  • 1/2 cup vegetable oil
  • 1/2 tbsp liquid dish washing soap

Directions:

  1. Mix ingredients well in a lidded glass jar.
  2. Add 1 1/2 teaspoons of the solution per each cup of water in the spray bottle and store remaining solution in the jar in the refrigerator.
  3. Soak spray the infested plants and surrounding soil.
  4. Repeat the rinsing and spraying for two more days and then use the solution thereafter once a week.
  5. Do not spray when direct sun is on the plants because the combination of the sun rays and solution will burn the leaves.

Note: On the third and fourth days I did find a couple of renegade aphids on the stems and gave them a quick spray. When I checked each morning thereafter, those same little guys were brown and dead. I have absolutely no clue how or why but it gave me great satisfaction. ;-)

Tip: Tips For Getting Rid of Aphids

There are insecticidal soaps on the market, however, I normally just take a small spray bottle with tepid water and a few drops of a mild detergent soap. It is much less expensive and I particularly like the "green" detergent soaps.

Controlling aphids takes spraying the leaves (both top and bottom) and also I spray the top of the soil. I do this every day (sometimes twice a day if the infestation is severe) for at least 3 to 5 days. It is important to keep checking the plant every day or two, since there may be a new hatch of aphids.

For plants that are outdoors having lady beetles is one of the best solutions. The lady beetle larvae just love to munch on the aphids.

As a side note, if you notice ants on a plant that has aphids you will find that the ants are actually "herding" the aphids. They love the sweet nectar that the aphids produce and they keep and protect the aphids as we would do with cattle, sheep, or goats. I mentioned this to a friend at our office who had ants and aphids on a plant and at first he thought I had totally lost my mind when I said the ants were herding their aphids. After I explained the relationship between the two, he seemed to understand and didn't question my sanity.

Tip: Onion or Garlic Juice To Deter Aphids

If buying ladybugs is not an option, I have been successful making a spray made from a boiled onion or garlic. Strain the juice and spray on the plants affected by aphids. This works for me. Tobacco juice is also effective.

If you use any type of spray, even something like Safer Soap, on your plants, it will take them a couple of weeks to recover, so I use plain old water to get rid of aphids.

Place a plant in the kitchen sink, use the sprayer to spray the under-side of each leaf, washing off the aphids. If any fall into the soil, it's OK, the aphids won't climb back up.

You need cabbage dust. Check garden supply shop, farm supply.

Question: Aphids on Milkweed Plants in Butterfly Garden

I read the answer re: milkweed for butterflies. I have a much harder time trying to grow them, from seed-starting, to trying to keep the sucking aphids off every day. Your other grower stated he had grown "tons" of milkweed in Spring Hill, FL.

I spray regularly with soapy water, but that's not getting rid of enough in my butterfly garden. I have sandy soil, water, open sun exposure. What am I doing wrong? Thanks so much.

Phyllis: I forgot to mention that the only reason I grow tropical milkweed is that they are a host plant for the monarch butterflies. The caterpillars are going to totally strip off every leaf from the plant so I don't care about the aphids. After all of the leaves are gone and the caterpillars have climbed my wooden fence and are tucked snug in their chrysalis I cut the plant down to about 8 inches off the ground and they start to grow all over again. You can do the same thing since you are only about 2 hours from me. The monarch butterflies like my zinnias, verbena and vincas also but those are not host plants.

According to Colorado State University you want a 2% solution of dish soap to water, for example add 4 teaspoons of dish soap to a quart of water. See documentation at http://www.ext.colostate.edu/pubs/insect/05547.html/ for complete article and a chart of dilutions.

Using sprays on white flies can and does kill other critters. There are some effective systemic products but same result. The biggest concern is bees on flowering plants. If they have white flies I would only use a non residual contact killer. Bees are too important to indiscriminately kill.

Yes, fertilize and you should get more and bigger blooms. Be sure you don't over-fertilize or you will get lots of lush green leaves and no blooms.

Another idea is planting garlic or green onions in the area. I have little green onions which put up their own seed "heads" (multiplier bulbs), so there's always more to plant and replace those picked for salads, etc. This is also good anti-thrip on the rosebush protection.

Question: Aphids on My Roses

Aphids are invading my roses, anything organic that I can use? Tips from the ThriftyFun community.

Try washing them off with the garden hose first. A few high-pressure bursts of water will dislodge most of them. You can support the stems with your hand while spraying if you're worried about them breaking. You may need to spray them every other day for awhile to eliminate them. Otherwise, use a safe, commercial insecticidal soap or make your own with 1 tbsp liquid dish soap and two cups of water.

Strong smelling roots and spices such as garlic, onions, horseradish, ginger, rhubarb leaves, cayenne and other hot peppers, are all known to repel insects. To add any one (or all) of these to your spray, chop them finely and put them into a glass jar. Add 2 cups of boiling water, cover tightly and let everything stand over night. The next day, strain off the liquid and add your dish soap. Freeze any leftover mix to use the next time.

Good Luck!

Ladybugs

Ladybugs. I believe you can actually buy some, but they DO eat those aphids.

By smcarney

RE: Aphids on My Roses

This is the simplest one to fix. Mix soap, not detergent, with water and mix it up. Spay over roses and aphids are history. Dish soap is just fine. Spruce also get aphids. Any spruce needs a dose of soap and water to get rid of aphids. Don't go to the store and buy the commercial soap, it is the same thing.

Pulling Aphids With Gloves

I have been pulling aphids (squishing) them with gloves every spring for years. I do use a soap solution to "drown" Japanese Beetles, which appear on roses (and other plants) later in the season. The beetles are weak in the mornings, and you can push them into a cup of soapy water.

Plant Onions Near Roses

My mother used to work as a secretary at Ohio State University in the botany department. She once heard that planting onions around roses keep aphids away. She had a miniature rose bush and placed a pot of chives (onion family) near it and the aphids left, never to return! The professors gave her a good-natured teasing about that one, but it sure worked!

Try Rubbing Alcohol

I know of two methods that both work well. One is ladybugs, they eat aphids. The other is rubbing alcohol. Now if it's the entire plant you'll want to dilute it and put the mixture in a spray bottle but if it's for just a few leaves on a plant you can dab a cotton ball in the rubbing alcohol and swab the leaves.

I've thought of the ladybugs, but have only seen them in groups of 1,500. Imagine that many bugs in your yard! Eeks. I might try the soap route next.
