The bald cypress tree (Taxodium distichum) is a distinctive and beautiful conifer native to swampy areas and wetlands of the southeastern United States. With its feathery green foliage, knobby knees, and attractive pyramidal form, the bald cypress makes a great addition to many landscapes. However, like any tree, it can become susceptible to nuisance pests like fruit flies that can damage its health and appearance.
Fruit flies are tiny insects just 1/8 to 1/4 inch long that are drawn to decaying, fermenting organic material They lay their eggs on ripe or overripe fruit, vegetables, fungi or other decaying plant matter. The larvae hatch within a day and begin feeding, maturing into adults within 8 to 10 days. Then the cycle repeats, allowing populations to explode rapidly
If fruit flies have found their way to your bald cypress, immediate action is crucial to get the infestation under control and prevent further damage Here is a comprehensive guide to effectively get rid of fruit flies on your bald cypress trees
Understanding Fruit Fly Infestations on Bald Cypress
Fruit flies on bald cypress trees likely originate from overripe ornamental fruit, fallen branches or cones lying on the ground, or damp potting soil. Female fruit flies seek out moist organic materials to lay their eggs. Ideal breeding grounds include:
- Rotting fruit, vegetables or moldy debris under the tree
- Excessively wet soil or standing water
- Poor drainage leading to soggy soil
- Decaying plant material or leaf litter
Within days, the eggs hatch into larvae that feed on decaying matter They eventually pupate and emerge as adults in about a week to continue the lifecycle
Left uncontrolled, fruit fly populations multiply exponentially. The swarming adults are an annoying nuisance, while their feeding larvae can damage roots, foliage and plant health. Acting quickly at the first signs of infestation is key.
Effective Ways to Eliminate Fruit Flies on Bald Cypress
Getting rid of fruit flies involves removing breeding sources, traps, and targeted treatments. Combining methods is most effective for control.
Remove Breeding Sources
Cut off fruit fly breeding by:
-
Clearing fallen fruit/vegetables, wet leaves, etc from around the tree.
-
Pruning dead branches and disposing of cuttings away from the tree.
-
Allowing soil to dry out partially between waterings.
-
Improving drainage in potted trees or in the ground.
-
Cleaning out excess moss, mulch, or debris from the soil surface.
Use Traps
Traps draw in adult flies to capture and kill them:
-
Make traps from jars baited with apple cider vinegar + dish soap.
-
Use commercial fruit fly traps with sticky cards or pheromone lures.
-
Hang yellow sticky strips coated with adhesive near trees.
-
Try wine, beer, soda, etc as bait in traps – they are attracted to fermenting sugary liquids.
Position traps on branches, the soil surface, or suspended nearby. Replace bait regularly to keep catching flies.
Apply Targeted Sprays
Insecticidal soaps, horticultural oils, and other organic sprays can eliminate fruit fly adults and larvae on contact. Spray tree trunks, leaves, and soil around the base to control populations. Repeat applications may be needed. Follow all label directions carefully.
Release Beneficial Nematodes
Applying beneficial nematodes (steinernema feltiae) to moist soil introduces parasites that attack fruit fly larvae and pupae in the soil and compost. They provide biological control and spare the tree.
Call in Professionals
For severe fruit fly infestations, contact a certified arborist. They have access to commercial-grade insecticides that can penetrate soil and control larvae. Soil drenches and trunk injections may be recommended in difficult cases.
Prevention Tips to Avoid Fruit Flies on Bald Cypress
Prevention is the best cure when it comes to fruit flies in your bald cypress trees. Follow these tips to make your trees less susceptible:
-
Pick up fallen fruits/vegetables promptly.
-
Remove trash, wet leaves, and organic debris around trees.
-
Follow proper watering and fertilization practices to avoid soggy soil.
-
Improve drainage in potted trees or areas with poor drainage.
-
Allow soil to dry out partially between waterings.
-
Clean up diseased or decaying tree parts and foliage.
-
Introduce beneficial nematodes preventively to soil annually.
-
Use pheromone traps proactively to monitor for early activity.
With vigilance and swift action at the first sign of fruit flies, you can protect your beautiful bald cypress trees from damage and enjoy their graceful presence in your landscape. Combining sanitation, traps, organic treatments, and prevention will help keep fruit flies at bay.
Cypress Leaf Beetle: Systena marginalis
Recognition: Foliage will appear discolored, turning into a bright to dark red with small, linear gouges (approx. 1/10-inch long) in the needles. Adult beetles are small (approx. 1/5-inch long) with a pale-yellow head and body and black markings on the outer margins of the body. They congregate in large numbers in tree crowns and feed on needles. Larvae feed on roots of grasses and weeds.
Contributing Factors: Adults are active in June and July. Drought or other stress factors can bring on similar needle color change, so it is important to properly scout and identify beetles.
Management Recommendations: In the nursery, direct sprays at adults when they are found or apply larvicide to soil in grass and weeds around the nursery. In landscape trees, trees will usually refoliate in the same growing season and no control is needed (Jacques 1987).
Cypress Twig Gall Midge: Taxodiomyia cupressiananassa
Recognition: Heavy, spongy galls of varying sizes are created when female flies lay their eggs on newly developing leaves. The oval, green galls are heavy enough to cause branches to droop under their weight if there are too many on the branch. Each gall may contain up to 15 yellow-orange maggots in individual cells. In the autumn, the galls turn brown and drop to the ground with the leaves, and the larvae over-winter in the gall. The adults emerge as flies and can be found for about a month beginning in mid-May. There are two generations per year.
Contributing Factors: The main contributing factor of cypress twig gall midges is previous infestations of this insect.
Management Recommendations: To reduce the number of galls in a new season, rake and destroy the fallen leaves and galls. Sprays can be directed at adults when they are scouted, but there are many natural enemies and biological controls of this insect (Gomez and Mizell 2013).
Recognition: Mealybugs are soft-bodied insects with piercing-sucking mouthparts and a wooly, white, waxy covering. A byproduct of mealybug feeding is sticky honeydew, which coats infested foliage and provides a medium for growth of black sooty mold fungi. Mealybug reproduction is increased in humid and hot environments.
Contributing Factors: Contributing factors for mealybugs, specifically for Baldcypress, is unknown.
Management Recommendations: Predators (like lady bug larvae) can control many mealybug infestations in the landscape. The waxy covering protects the insects from sprays. Horticultural oils or systemic insecticides can be effective in controlling mealybugs, but because Baldcypress is very sensitive to horticultural oils, extreme caution should be used when making the decision to apply (UF/IFAS 2015).
Recognition: The Baldcypress Rust Mite is a microscopic eriophyid mite, most active during the warm season, which causes browning of interior needles. It overwinters in bark crevices, ready to reproduce and infest new growth in the spring. The mites mouthparts rasp the leaf cells, causing the needles to become yellowish and then brown. Mites can be seen with a 10-power hand lens, and their white cast skins are the best diagnostic.
Contributing Factors: Warm weather causes very rapid reproduction.
Management Recommendations: Carbaryl, dicofol, and oxythioquinox will knock down this mite with thorough foliage coverage (Nixon and Sheltar 1998). Please consult the most up-to-date regulations before applying any pesticides.

What spray kills fruit flies instantly?
How to get rid of flies from trees?
How do you get rid of fruit flies?
In a small bowl or cup, mix together water with a couple drops of dish soap and a tablespoon or two of cider vinegar. The vinegar will attract the fruit flies, while the dish soap will break the surface tension on the liquid so they will fall in and drown in the water. You can also use the funnel and jar method to keep everything contained.
How to keep fruit flies away from plants?
If space is at a premium, the leaves of these herbs can also be placed around the base of an affected plant or in a muslin bag nearby. Essential oils derived from any of the above-mentioned plants, as well as eucalyptus leaves and camphor trees are also a great way to keep fruit flies away from plants. They are put off by the smell and move away.
