What You Will Learn About Vinegar and Aphids:

5 Reasons NOT To Use Vinegar To Kill Aphids On Roses

  1. Potential Plant Damage: Vinegar contains acetic acid. While effective against aphids, it can also harm roses and other plants if used too often or in high amounts.
  2. Weak Better Organic Aphid Control Option: Beneficial bugs and insects, neem oil spray, insecticidal soap, and parasitic wasps outperform vinegar.
  3. Risk of Leaf Burn: Spraying a 50/50 solution of vinegar and water on roses could impact plant health.
  4. Environment Impact: When vinegar gets into the soil, the acid can hurt the tiny helpful bugs in the soil and damage other garden plants.
  5. Not A Long-term Gardening Solution: Vinegar can help control aphids for a short time. It does not remedy the aphid problem. The aphids keep coming back.

What Is An Aphid?

An aphid is a small, soft-bodied insect pests that feed on the sap of plants. Aphids are part of a bug family called Aphididae. The family is in the order known as Hemiptera. Other sap-sucking bugs in the order include whiteflies and plant scale insects.

Aphids are usually less than 1/4″ inch in length. These pests have different colors, like green, brown, black, or others, which vary based on the type of aphid. Their bodies are shaped like a pear. They have long antennae, and two tube-like structures called ‘cornicles’ on their abdomen.

Aphids can reproduce fast! They damage plants in three main ways:

  • Stunting growth
  • Deforming plant leaves
  • Can carry and spread plant diseases

Why Do Aphids Go Near My Roses?

Bees or butterflies, as pollinators, are drawn to roses because of their fragrances. Pests, like aphids feed on plant sap in your plants. Beetles, aphids, and mites feast on roses ruining your garden’s stability.

If only a few sap-sucking aphids drink a plant’s juices, you might not see extensive damage. Aphids, when present in hundreds or even thousands on a plant’s stems, leaves, or growing tips, can consume more sap than the plant can produce.”

Dr. Louis Pyenson (Entomologist), author of “Fundamentals of Entomology and Plant Pathology”

How To Prevent or Get Rid of Aphids on Roses Without Vinegar

Vinegar will kill aphids. However, there are other effective methods that you can also consider. Below are some better, safer options on how to get rid of aphids on roses.

Diatomaceous Earth

  • Diatomaceous Earth, or DE, is a type of natural product, a powder. The dust works to kill aphids, also known as plant lice, by cutting into their hard outer body, making them dry out. You can use this dust to guard your rose plants by putting it around them. You can even put it straight on the aphids. More on Diatomaceous Earth.

Neem Oil

  • Neem Oil is a potent essential oil derived from the neem tree. Natural Neem Oil is one of the best, most effective, organic ways to kill aphids. Neem makes a great aphid spray for roses.

    Neem disrupts the insects’ hormonal system and does not harm the plant. This disruption leads to the aphids’ inability to reproduce. Mix Neem Oil with water as directed on the label and spray it on your affected rose plants. Neem is also a great option for getting rid of aphids on indoor plants.

  • Garden Hose: Using a garden hose can sometimes be an easy solution. If you spray a strong stream of water, you can get the aphids off your plants and decrease their number. But remember, be gentle so your plants don’t get hurt when you’re doing this.

Insecticidal Soap

  • Insecticidal Soap: People who like organic gardening have used insecticidal soap to get rid of aphids for decades. It helps kill bugs with soft bodies. Here’s how you make it:

Beneficial Insects

  • Beneficial Insects: Using helpful bugs is a great way to control aphids on your roses without using chemicals. Ladybugs, lacewings, and tiny wasps are all good bugs that work to keep aphids under control in the garden. Ladybugs are voracious aphid eaters who consume up to 50 aphids daily.

Aphid Spraying Tips

When you spray to kill aphids, make sure to cover more than just the tops of the leaves and petals. Cover the entire plant! Don’t forget about the undersides of the leaves and the stem, where aphids like to hide.

Frequently Asked Questions About Vinegar and Aphids

At What Temperature Do Aphids Die?

Aphids are sensitive to temperature changes. Different aphid species will survive in differing temperatures. One study subjected juvenile aphids to 95° degrees Fahrenheit (35° C) for four hours.

The results? The heat-treated aphids lived. But the heat sterilized the aphids so they could not have babies.

How low the temperature must go to kill aphids is debatable. Some report sustained temperatures below -14° degrees Fahrenheit are needed. But the aphid eggs will still survive.

How Well Will Vinegar Kill Aphids?

Vinegar is effective and works very well at getting rid of aphids. The vinegar kills the aphid when it comes into direct contact with the pest. It is always recommended to use vinegar with caution.

What Is the Best Time To Start Spraying Insecticides For Aphids in the Spring?

The best time to start spraying insecticide in the spring for pest control depends on the temperature. Few gardeners know that temperatures affect the appearance of pests, including aphids.

  • As temperatures rise, insect activity and pest numbers increase.
  • Aphids begin hatching when average temperatures reach 50° degrees Fahrenheit.
  • The aphid enemies don’t hatch until average temperatures reach 60° Fahrenheit.
  • Aphids can get a head start of ten days or two weeks because of this.
