  • Damage to flowers so they cannot stand upright
  • Leaves wrinkled and curled
  • Drying soot will cover the leaves and stems
  • A fragile shrub because its nutrients are taken
  • Honeydew or a sweet sticky substance will fill the underside of the leaves
  • Instead of taking care of roses, you end up with aphids farming

In this article, we will discuss the steps to eradicate aphids. Before you start spraying aphids on roses, here’s what you should know :

  • The first step in controlling rose aphids
  • Chemical or natural agents that will get rid of aphids
  • Knowing the natural enemies that eat aphids on rose bushes
  • Common ways to kill rose aphids

Spraying at an inappropriate time of growth for aphids on roses can reduce the effectiveness of its elimination. In fact, in some cases, you can destroy the entire ecosystem. Here are tips from professional gardeners on maintaining your rose bush by following the laws of nature.

In the spring, when the temperature reaches 50° Fahrenheit, the eggs begin to hatch. Furthermore, for 10-14 days, these beneficial insects will experience growth in adulthood. At this time you can spray the insects on roses before they become too big a colony. Keeping the pests in until the predator is gone can help balance.

This way you can reduce the need for spraying. Don’t worry, your spray won’t harm any beneficial insects.

You may have experimented with controlling annoying insects by spraying a garden hose to get rid of them with a strong spray of water. While this step will blow away your insects, your rose bush will also be soaked. So we don’t recommend this method because water and moist rose leaves will produce powdery mildew or dark spots. Then it is better to use natural sprays as a solution.

What Chemical Or Natural Sprays To Kill Aphids on Roses?

Both chemical and natural sprays will get rid of annoying bugs. However, you always recommend using organic ingredients first before chemicals such as ​Acephate (Orthene)​, Merit® 75W, Malathion, and so on. Insecticides to repel aphids on roses depend on several things that will be discussed later. You can use a homemade natural spray as follows :

  • Liquid Soap Solution Spray
  • Insecticidal Soap
  • Neem Oil
  • Rubbing Alcohol
  • Horticultural Oil

Liquid Soap Solution Spray

You can make a spray with a simple solution for minor outbreaks on your plants. Combine water and dish soap in a spray dish. Don’t forget to make sure that the dish soap you use doesn’t contain added ingredients such as oils, moisturizers, or other chemicals.

Use a quart measure of water with one tablespoon of soap. For one gallon you can use 4 to 5 tablespoons. Then stir and use. To ensure the disinfection of pests, spray all infected layers including the underside of the leaves to allow insects to be exposed to this solution.

Insecticidal Soap

You can use soaps that contain fatty acids such as “Castile Soap”. This soap can remove cells and a protective layer so that aphids on roses can die from dehydration. This insecticidal soap is easily found in various brands like Safer.

Neem Oil

Use of neem oil is known as a control option for aphids, spider mites, scale insects, mealybugs, and several other favorite plant insects. To be precise, this oil is a natural insecticide for soft insects, but it can also irritate larger, hardier insects such as beetles. As a side note, Japanese beetles also attack rose bushes and can be a 2in1 choice for you. This oil also has low toxicity to animals and humans.

Rubbing Alcohol

You can use 70% alcohol as a home remedy for insect control. Use a cotton ball and dip a little in the alcohol. Then, apply it directly to the aphids on roses to kill it. Use a ratio of 1/4 cup of alcohol to 1 cup of water. Please be careful because the leaves of the plant can burn when applying alcohol on a sunny day. Use it on a cloudy day.

Don’t use vinegar in this spray! Some sources say that you can also use this spray. However, it is not only the insects that die but also your roses.

Horticultural Oils

If you still can’t get rid of aphids on roses using one of the methods above, you can use horticultural oil as a last resort. Use an oil that is now refined and “light”. Apply the oil to the plants, it will dry out and is not toxic to plants, but is very effective in pest control. This oil is safe to use on a variety of plants when pest colonies emerge. Use this “inactive spray” the time the child must use the oil, not necessarily the type of oil used. Pay attention to the label of this horticultural oil and make sure it includes :

  • Inactive spray
  • Volck oil
  • Summer oil
  • All seasons spray oil

As a side note, you must know exactly the right time to use this good insect. Natural predators for controlling these unwanted aphids include :

  • Ladybugs or Lady beetles

Ladybugs or Lady beetles

You know what a ladybug looks like, right? It turns out that this spotted insect is a voracious insect predator and an enemy of the famous aphids on roses. This predatory insect can prey on more than 200 soft insects every day. Ladybugs of all ages roam in search of soft-bodied insects all day long. Ladybugs will use their jaws to catch and prey on these soft insects.

Hoverfly

The larvae of hoverflies love soft-bodied pests such as plant scales, thrips, and aphids on roses. These insects are easily found in colonies that together devour their prey. Hoverflies are also good pollinators for your plants. This hoverfly is second only to the lad beetle or ladybug with its ability to destroy large numbers of aphids.

Green Lacewings

These green lacewing insects are notorious for being very greedy and aggressive due to their high appetite. They have even nicknamed the “aphid lion” because of that. After hatching, these lacewing larvae start looking for pests such as aphid in roses. Not only aphids, but he also devours various soft-bodied insects.

Parasitic Wasps

This parasite-eating wasp is small and lives on a host of other insects as long as it is larvae. Adult wasps will lay eggs in the bodies of other insects with spiky egg-laying structures. Then the young parasite eggs will hatch and begin to eat the contents of this “host” and kill it. You can find a variety of them in different colors and sizes, they are generally black or brown and medium size is the largest size. Unlike other wasps, this wasp does not sting and feeds on other insects.

These are two parasitic wasps common in gardens:

  • Ichneumon Wasp
  • Aphidius colemani​ (Braconid wasp)

Here’s pest control management for your aphids on roses or other plants in the garden :
