What is the Rose Stem Borer?

The Rose Stem Borer is a common pest that affects rose plants. It is a type of insect that burrows into the stems of rose plants, causing damage and weakening the plant. The larvae of the stem borer feed on the inner tissues of the stems, leading to wilting, stunted growth, and even death of the plant if left untreated.

Description Damage Prevention
The Rose Stem Borer is a type of insect that belongs to the clearwing moth family. They bore into rose stems, causing wilting, dieback, and eventually death of the plant. Regular inspection of plants, pruning infected stems, and applying insecticides can help prevent infestation.
Adult borers resemble wasps and are active during the day. They tunnel into the stems, disrupting the flow of water and nutrients, leading to weakened plants. Planting resistant rose varieties and maintaining good plant health can reduce the risk of infestation.
Larvae feed inside the stems, leaving behind frass (sawdust-like excrement) and causing internal damage. Infested plants may show stunted growth, wilting, and may eventually die if left untreated. Removing and destroying infested canes during winter pruning can help control the population.

How to Identify Rose Stem Borer Infestation?

Identifying a rose stem borer infestation can be challenging as the larvae are hidden inside the stems. However, there are some signs to look out for. These include wilting or drooping of branches, holes or tunnels in the stems, sawdust-like frass near the base of the plant, and presence of adult moths or beetles around the roses. Regular inspection of your rose plants can help in early detection of an infestation.

  • Look for wilting or dying rose stems. If you notice stems that are turning brown or black and wilting, it could be a sign of rose stem borer infestation.
  • Inspect the stems for entry holes. Rose stem borers create small entry holes on the stems, usually near the base. These holes may be accompanied by sawdust-like frass around the area.
  • Check for tunneling inside the stems. Carefully cut open the affected stems and look for tunnels or galleries created by the borers. These tunnels may be filled with sawdust-like frass and larvae may be present inside.

What are the Damage Caused by Rose Stem Borer?

Rose stem borer can cause significant damage to rose plants if not controlled. The larvae tunnel through the stems, disrupting the flow of water and nutrients, which leads to wilting, yellowing leaves, and overall decline in plant health. Severe infestations can even result in death of the plant. It is important to take prompt action if you notice any signs of stem borer infestation to minimize damage.

  1. Stunted growth of the rose plant
  2. Wilting and yellowing of leaves
  3. Presence of holes and tunnels on the stems
  4. Dieback of branches and shoots
  5. Increased susceptibility to other diseases and pests

How to Prevent Rose Stem Borer Infestation?

Preventing rose stem borer infestation starts with maintaining a healthy garden environment. Proper sanitation practices such as removing and destroying infested plant debris can help eliminate overwintering sites for the pests. Regular pruning and monitoring of rose plants can also help in early detection and control of any infestations. Additionally, using insecticides or biological controls targeted specifically for stem borers can be effective preventive measures.

Plant Healthy Roses Prune and Remove Infested Stems Use Preventive Measures
Choose healthy and disease-resistant rose varieties for your garden. Regularly inspect your roses and prune and remove any infested stems or canes. Apply preventive measures such as using insecticidal soaps or neem oil to deter stem borers.
Ensure proper soil drainage and provide adequate sunlight and air circulation. Dispose of pruned stems properly to prevent re-infestation. Keep the garden area clean and free from debris to discourage stem borers.
Monitor and control other pests that may weaken roses and make them more susceptible to stem borers. Consider using physical barriers like sticky traps or netting to prevent adult stem borers from laying eggs. Encourage beneficial insects like parasitic wasps that can help control stem borer populations.

What are the Natural Predators of Rose Stem Borer?

Natural predators play an important role in controlling rose stem borer populations. Some of the natural enemies of stem borers include parasitic wasps, predatory beetles, and birds. These predators feed on the larvae or eggs of the stem borers, helping to keep their populations in check. Encouraging biodiversity in your garden by planting native flowers and providing habitat for beneficial insects and birds can help attract these natural predators.

The natural predators of rose stem borer include birds, parasitic wasps, predatory beetles, and spiders.

How to Control Rose Stem Borer Infestation Organically?

Controlling rose stem borer infestation organically can be achieved through various methods. One approach is to use biological controls such as nematodes or beneficial nematodes that target the larvae of the stem borers. Another method is to apply botanical insecticides derived from plants such as neem oil or pyrethrin. Additionally, practicing good cultural practices like proper pruning, regular inspection, and maintaining plant health can help prevent and control infestations.

To control rose stem borer infestation organically, use beneficial insects, neem oil, prune affected stems, and maintain a healthy garden ecosystem.

When is the Best Time to Treat Rose Stem Borer?

The best time to treat rose stem borer depends on the life cycle of the pest. In general, it is recommended to start treatment in early spring when the adult moths or beetles emerge and lay their eggs on the rose stems. This allows for targeted control measures before the eggs hatch and the larvae burrow into the stems. Regular monitoring throughout the growing season is also important to catch any infestations early and take appropriate action.

Early Spring

The best time to treat rose stem borers is in early spring when the adult borers start emerging from their overwintering sites in the soil. This is usually around late March to early April, depending on your location. Treating at this time helps prevent the adults from laying eggs on the rose canes.


Another good time to treat rose stem borers is in mid-summer when the eggs that were laid by the adults have hatched and the young borers are actively feeding on the rose canes. Treating at this stage helps control the population and reduce damage to the plants.


Treating rose stem borers in the fall is also beneficial as it helps eliminate any remaining borers before they go into hibernation for the winter. This can prevent them from causing further damage to the roses and reduce the chances of reinfestation in the following spring.
