June 22, 2023
Figs are delicious and nutritious fruits enjoyed by many, but they often fall victim to pesky fig beetles. These beetles can wreak havoc on your fig trees, causing damage to both the leaves and the fruit.
If you’re wondering how to prevent fig beetles from inflicting harm on your precious figs, you’ve come to the right place. In this article, we’ll explore various strategies and techniques to help you protect your fig trees and preserve a bountiful harvest.
What are fig beetles and why are they a threat to your figs?
Fig beetles, also known as green fruit beetles or figeater beetles, are iridescent insects that belong to the scarab beetle family. They are attracted to ripe and decaying fruit, with figs being one of their favorite treats.
Fig beetles lay their eggs in the soil near fig trees, and once the larvae hatch, they feed on the roots. This can weaken the tree, making it more susceptible to disease and other pests. Additionally, adult fig beetles chew on the leaves and fruit, causing cosmetic damage and reducing the overall quality of the figs.
To protect your figs from the threat of fig beetles, it’s essential to understand their life cycle and behavior. By knowing their patterns, you can implement preventive measures that will significantly reduce their impact on your fig trees.
How can you identify the signs of fig beetle damage on your fig trees?
Detecting fig beetle damage early on is crucial for effective prevention and control. Keep an eye out for the following signs of infestation:
a) Leaf damage: Look for irregular holes or notches on the leaves, as well as skeletonized foliage. Fig beetles feed on the foliage, leaving behind visible evidence of their presence.
b) Fruit damage: Ripe figs may exhibit surface scars or small punctures caused by the beetles’ feeding activity. Inside, you may find larvae or their excrement.
c) Tree stress: Weakened fig trees may display stunted growth, yellowing leaves, or signs of root damage. Fig beetles can contribute to these symptoms by attacking the roots.
By promptly identifying these signs, you can take immediate action to prevent further damage and protect your figs.
Are there natural predators that can help control fig beetles?
Nature has its way of balancing populations, and fig beetles have their fair share of predators. Certain birds, such as blue jays and mockingbirds, feed on adult beetles, while reptiles like lizards and toads prey on the larvae. Encouraging these natural predators to frequent your garden can provide some level of control over fig beetle populations.
Additionally, beneficial insects like parasitic wasps and nematodes can be introduced to your garden to target fig beetle larvae in the soil. These natural enemies help keep the beetle population in check without the use of harmful chemicals, promoting a healthier and more eco-friendly environment.
What are the most common methods to prevent fig beetle infestation?
Preventing fig beetle infestation requires a multi-faceted approach. Here are some effective methods to consider:
a) Harvest figs early: Picking figs before they fully ripen reduces their attractiveness to fig beetles. Harvesting regularly and promptly removing fallen fruit will help break the beetle’s life cycle.
b) Physical barriers: Covering your fig trees with netting or floating row covers can create a physical barrier that prevents beetles from reaching the fruit. Ensure the barrier is secured tightly to prevent any gaps.
c) Trap crops: Planting trap crops, such as sunflowers or marigolds, can divert fig beetles away from your fig trees. These sacrificial plants lure the beetles, reducing their impact on your figs.
d) Companion planting: Consider planting herbs and flowers that repel fig beetles, such as basil, garlic, or calendula, near your fig trees. The strong scent or natural compounds released by these plants can deter the beetles.
e) Soil management: Maintaining proper soil moisture and fertility levels can help keep your fig trees healthy and less prone to beetle damage. Avoid overwatering, as damp soil can attract beetles.
By implementing a combination of these methods, you can significantly reduce fig beetle infestation and protect your figs.

Is it possible to deter fig beetles using organic and eco-friendly solutions?
Yes, it is indeed possible to deter fig beetles using organic and eco-friendly solutions. Here are a few options to consider:
a) Neem oil: Neem oil is a natural insecticide derived from the neem tree. It has repellent properties that can discourage fig beetles from feeding on your figs. Dilute neem oil according to the manufacturer’s instructions and apply it to the foliage and fruit of your fig trees.
b) Homemade sprays: You can create a homemade spray using ingredients like garlic, hot pepper, or vinegar. These sprays emit strong odors that repel fig beetles. However, it’s important to test the spray on a small portion of your fig tree before applying it extensively.
c) Beneficial nematodes: Beneficial nematodes, microscopic worms that feed on insect larvae, can be purchased and applied to the soil around your fig trees. These nematodes specifically target fig beetle larvae, providing natural and effective control.
d) Floating row covers: As mentioned earlier, floating row covers act as a physical barrier against fig beetles. They are made of lightweight fabric that allows sunlight and water to reach the plants while keeping beetles at bay.
Remember that organic and eco-friendly solution may require more frequent applications compared to chemical pesticides. Regular monitoring and reapplication may be necessary to ensure continued effectiveness.
How important is regular fig tree maintenance in fig beetle prevention?
Maintaining a regular schedule of fig tree care is crucial for preventing fig beetle infestation. Proper maintenance practices promote the overall health and resilience of the trees, making them less susceptible to beetle damage. Here are some essential maintenance tasks to consider:
a) Pruning: Prune your fig trees during their dormant season to remove dead or diseased branches and improve air circulation. Pruning also helps maintain the tree’s shape and size, making it easier to monitor and control fig beetle activity.
b) Sanitation: Clean up fallen leaves, fruit, and debris around your fig trees regularly. These organic materials can attract fig beetles and provide them with breeding grounds. By keeping the area clean, you reduce the potential for beetle infestation.
c) Watering: Water your fig trees deeply and evenly to maintain consistent moisture levels in the soil. Avoid overwatering, as excess moisture can attract beetles and create favorable conditions for their larvae.
d) Fertilization: Provide your fig trees with a balanced fertilizer according to their specific needs. Healthy, well-nourished trees are better equipped to resist fig beetle damage.
By following a comprehensive maintenance routine, you’ll create an environment that discourages fig beetles from infesting your fig trees and damaging the fruit.
Can physical barriers effectively keep fig beetles away from your figs?
Physical barriers, such as netting or floating row covers, can be highly effective in deterring fig beetles from reaching your figs. These barriers create a physical obstacle that prevents the beetles from accessing the fruit. Here’s how to use them effectively:
a) Netting: Cover your fig trees with fine-mesh netting to protect them from fig beetles. Ensure the netting is securely fastened at the base of the tree and doesn’t leave any gaps. This prevents beetles from laying eggs or feeding on the figs.
