Fig beetles target ripening fruit, so removing overripe produce and treating grubs stops them early. If you’ve ever walked out to your garden only to find half-eaten figs or peaches with large, jagged holes, you’ve likely met the fig beetle. These shiny, greenish-black beetles can ruin a harvest fast. Learning how to get rid of fig beetles is essential for protecting your fruit trees and garden plants. This guide covers practical steps to control adults and grubs without harsh chemicals.
Fig beetles are also called June bugs or figeaters, but they’re a different species. They fly during the hottest part of the day, which makes them hard to catch. The adults feed on soft, ripe fruit, while the grubs live in compost or manure piles. You need to tackle both life stages to get lasting results.
Understanding Fig Beetles And Their Life Cycle
Before you fight them, know your enemy. Fig beetles (Cotinis mutabilis) are large, metallic green beetles common in warm climates. They emerge in late spring and stay active through summer. Adults are about 1.2 inches long and make a loud buzzing sound when they fly.
The females lay eggs in rich, organic soil—especially compost heaps or well-rotted manure. The eggs hatch into C-shaped grubs that feed on decaying matter. These grubs can grow up to 2 inches long. They pupate in the soil and emerge as adults the next year.
Understanding this cycle helps you break it. If you remove the grubs’ food source, you reduce the next generation. If you protect your fruit, you stop the adults from feeding. Both steps are part of any solid plan for how to get rid of fig beetles.
Identifying Fig Beetle Damage
Fig beetles leave distinct signs. You’ll see large, irregular holes in soft fruit like figs, peaches, plums, and grapes. The damage often looks like a scoop was taken out. Unlike birds, fig beetles don’t peck—they chew.
You might also notice the beetles themselves. They gather in groups on ripe fruit, especially on hot afternoons. Their metallic green shells shimmer in the sun. If you see them, act fast because they attract more beetles.
Why Fig Beetles Are Hard To Control
Fig beetles are strong fliers and can travel long distances. They also have a thick exoskeleton that resists some sprays. Plus, they feed during peak heat when many gardeners aren’t outside. This makes manual removal tricky.
Another challenge: the grubs live deep in compost or soil. You might not even know they’re there until the adults appear. That’s why prevention and early action matter more than reactive spraying.
How To Get Rid Of Fig Beetles
Now we get to the core methods. This section covers physical removal, habitat changes, and natural controls. Each step works best when combined with others. Follow these steps consistently for the best results.
Hand-Picking And Trapping Adults
Hand-picking is simple but effective. Go out during the hottest part of the day—noon to 3 PM—when beetles are most active. Wear gloves and drop them into a bucket of soapy water. The soap breaks surface tension so they drown quickly.
You can also use traps. Commercial fig beetle traps use a pheromone lure or a sweet bait like overripe fruit. Place traps away from your fruit trees to draw beetles away. Check and empty traps daily.
One tip: set traps early in the season before the population explodes. This catches the first wave and reduces egg-laying. Combine trapping with hand-picking for maximum impact.
Removing Overripe Fruit And Fallen Fruit
Fig beetles love overripe fruit. Pick fruit as soon as it ripens. Don’t leave fallen fruit on the ground—it’s a beetle buffet. Rake up any dropped fruit daily during peak season.
If you have a large tree, consider using a fruit catcher net. This catches falling fruit and makes cleanup easier. Compost the fallen fruit far from your garden, or better yet, dispose of it in sealed bags.
Removing the food source forces beetles to look elsewhere. This is one of the simplest and most effective steps in how to get rid of fig beetles.
Managing Grubs In Compost And Soil
Grubs thrive in compost piles and manure. If you have a compost heap, turn it regularly. This exposes grubs to predators and dries them out. You can also screen your compost before using it in the garden.
Beneficial nematodes are a natural control for grubs. These microscopic worms enter grubs and release bacteria that kill them. Apply nematodes to compost piles or soil in early spring or fall when grubs are active.
Another option: Milky spore powder. This bacterial disease targets grubs specifically. It takes a few years to establish but provides long-term control. Apply it according to package directions.
Using Row Covers And Netting
Physical barriers work well for small trees or bushes. Cover your fruit trees with fine mesh netting before the beetles emerge. Make sure the netting is secured at the trunk so beetles can’t crawl under.
Row covers can also protect vegetables and berries. Use them when fruit starts to ripen. Remove covers for pollination if needed, but replace them afterward. This method stops beetles from reaching the fruit entirely.
Natural Sprays And Repellents
Neem oil is a natural insecticide that repels fig beetles. Mix neem oil with water and a few drops of dish soap. Spray your fruit trees every 5–7 days during beetle season. Focus on the fruit and leaves.
Garlic spray is another option. Blend garlic cloves with water, strain, and spray on plants. The strong smell deters beetles. Reapply after rain.
Kaolin clay is a mineral spray that coats fruit with a fine powder. Beetles don’t like the texture and avoid treated fruit. Mix kaolin clay with water and spray thoroughly. It washes off easily at harvest.
Encouraging Natural Predators
Birds, lizards, and spiders eat fig beetles. Attract birds by providing water and native plants. Blue jays and mockingbirds are known to eat adult beetles.
Ground beetles and predatory wasps also help control grubs. Avoid broad-spectrum pesticides that kill these beneficial insects. Let nature do some of the work for you.
Preventing Future Infestations
Prevention is easier than cure. After you’ve dealt with the current beetles, take steps to stop them from coming back. This section covers long-term strategies.
Sanitation In The Garden
Keep your garden clean. Remove fallen fruit, dead leaves, and decaying plant matter regularly. Don’t let compost piles sit undisturbed for months. Turn them every few weeks.
If you use manure, compost it thoroughly before applying to the garden. Fresh manure attracts egg-laying females. Aged manure is less appealing.
Timing Your Harvest
Harvest fruit as soon as it’s ripe. Don’t wait for it to soften on the tree. Early picking reduces the window when beetles can feed. If you have more fruit than you can eat, consider preserving or sharing.
For figs, pick them when they’re fully colored but still firm. Check daily during peak season. A few minutes each day saves you from losing your whole crop.
Soil Management
Grubs need organic matter to survive. Reduce the amount of uncomposted material in your soil. Use raised beds with clean soil if you have persistent problems.
Apply beneficial nematodes annually as a preventive measure. This keeps grub populations low before they become adults. Combine with regular soil turning.
Common Mistakes To Avoid
Even well-intentioned efforts can backfire. Here are common mistakes people make when trying to control fig beetles.
- Using pesticides that kill pollinators. Fig beetles are active during the day when bees are also out. Spray in the evening to minimize harm.
- Ignoring the grub stage. If you only kill adults, grubs will emerge next year. Always treat both life stages.
- Setting traps too close to trees. Traps attract beetles, so place them at least 50 feet away from your fruit trees.
- Not cleaning traps regularly. Dead beetles release a smell that repels live ones. Empty traps every few days.
- Overwatering. Moist soil attracts egg-laying females. Water deeply but infrequently to keep the soil surface dry.
Frequently Asked Questions
What Is The Best Way To Get Rid Of Fig Beetles Naturally?
The best natural method combines hand-picking, neem oil sprays, and removing overripe fruit. Beneficial nematodes for grubs also help. Consistency is key—do these steps weekly during beetle season.
Do Fig Beetles Bite Humans?
No, fig beetles do not bite or sting. They are harmless to people and pets. They only feed on soft fruit and decaying plant matter. You can handle them safely with gloves.
How Long Do Fig Beetles Live?
Adult fig beetles live for about 2–3 months. They emerge in late spring and die by late summer. The grub stage lasts much longer—up to a year underground.
Will Fig Beetles Damage My Lawn?
Fig beetle grubs feed on decaying organic matter, not grass roots. Unlike Japanese beetle grubs, they don’t damage lawns. They are beneficial in compost piles because they break down material.
Can I Use Vinegar To Repel Fig Beetles?
Vinegar can repel some insects, but it’s not very effective on fig beetles. It may also harm your plants if sprayed directly. Stick with neem oil or garlic spray for better results.
Final Thoughts On Fig Beetle Control
Fig beetles can be frustrating, but they are manageable. The key is to act early and use multiple methods. Don’t rely on just one approach—combine sanitation, trapping, and natural sprays for the best outcome.
Remember that fig beetles are part of the ecosystem. They help break down compost and provide food for birds. Your goal isn’t to eliminate them completely, but to protect your fruit. With consistent effort, you can enjoy your harvest without sharing it with these shiny pests.
