We will explore the common insects that eat rose leaves, their reasons for doing so, and the best methods to keep them at bay. So, let’s dive in and protect those gorgeous blooms!

Why Do Bugs Eat Rose Leaves?

Holes on rose leaves

Bugs eat rose leaves for a variety of reasons. Some pests, such as caterpillars and sawflies, have a chewing habit and feed on rose leaves as a source of food. These insects consume the leaf tissue, causing irregularly shaped holes and areas on the leaf blades.

Other pests, like aphids, red spider mites, and thrips, feed on rose leaves by sucking the sap from them. These pests have specialized mouthparts that allow them to extract plant fluids, depriving the leaves of essential nutrients and causing damage.

Additionally, some insects, such as Japanese beetles, may feed on both rose flowers and foliage. These pests consume petals and skeletonize leaves, giving them a lace-like appearance.

It’s important to note that pests may target rose leaves for multiple reasons, including as a food source, shelter, or reproductive site. The specific reasons may vary depending on the insect species and its life cycle.

What Is Eating My Rose Leaves At Night?

Rose Slugs, Saw Flies, Aphids, Caterpillars, Red Spider Mites, and Thrips are common pests that can eat rose leaves.

These pests can cause damage to the leaves by feeding on them, resulting in holes, discoloration, and distortion.

6 Pests that Cause Holes on Rose Leaves

1. Rose Slugs (sawfly larvae): 

These are small, slug-like larvae that feed on the leaf tissue of roses. They skeletonize the leaves, leaving behind a lacy appearance.

2. Sawflies: 

Sawflies are related to bees and wasps and their larvae can feed on rose leaves. They chew on the leaf edges and can defoliate the plant if the infestation is severe.

3. Aphids: 

Aphids are tiny insects that suck the sap from rose leaves, causing them to curl, yellow, and distort. They also secrete a sticky substance called honeydew, which can attract ants and promote the growth of sooty mold.

4. Caterpillars: 

Various species of caterpillars, such as the rose leaf-rolling caterpillar, can feed on rose leaves. They chew on the leaves and can cause significant defoliation if left untreated.

5. Red Spider Mites: 

Red spider mites are tiny pests that suck the sap from the leaves, causing them to turn yellow and develop fine webbing. Heavy infestations can lead to defoliation and weaken the rose plant.

6. Thrips: 

Thrips are tiny, slender insects that feed on roses by sucking sap from the leaves and buds. They can cause silver streaking on the leaves and distortion of the flower buds.

How To Control Insects That Eat Roses?

To manage these pests, it is important to regularly inspect your rose bushes for signs of infestation and take appropriate action. To control insects that eat roses, there are several strategies you can employ:

  • Prune regularly:
    Remove any damaged or infested parts of the plant, including leaves, buds, and flowers. This helps reduce the population of pests and prevents further spread.
  • Attract beneficial insects:
    Encourage predators and parasitic insects that feed on pests by planting companion plants or providing suitable habitats, such as pollinator-friendly flowers or insect houses. Ladybugs, lacewings, and birds are examples of beneficial insects that can help control pests.
  • Apply insecticidal soap:
    Insecticidal soaps, made from potassium salts of fatty acids, can effectively control soft-bodied pests like aphids and spider mites. Follow the instructions on the product label for proper application.
  • Use horticultural oils:
    Horticultural oils, such as neem oil, suffocate and kill insects on contact. They can be effective against pests such as scale insects and spider mites.
  • Apply targeted insecticides:
    If infestation levels are high or other methods are not effective, you may consider using insecticides specifically labeled for rose pests.
    Systemic insecticides, such as those containing imidacloprid, can provide long-lasting protection by being absorbed into the plant’s tissues. Always follow the instructions on the product label and use caution when using insecticides.

It’s worth noting that a holistic approach that combines multiple strategies will likely yield the best results. Regular monitoring of your roses for pests is essential to catch infestations early and take appropriate action.

Please be mindful of potential environmental impacts and follow safe and responsible pest control practices.

It is recommended to consult with a local gardening expert or extension service for specific pest management strategies tailored to your region and the severity of the infestation.
