Why Fruit Flies are Attracted to Alice du Pont Mandevillas
To understand how to control fruit flies on your prized Alice du Pont mandevilla vines, it helps to know exactly why they are drawn to these plants in the first place. Here are the main reasons fruit flies gravitate to mandevilla vines:
-
The sweet nectar inside mandevilla flowers provides fruit flies with a delicious natural food source. They’ll happily feed on the sugary nectar.
-
Fruit flies are attracted to the smell given off by the blooms and foliage of Alice du Pont mandevillas.
-
These vines provide fruit flies with ideal breeding conditions. The moist soil, drainage issues, and decaying organic matter allow flies to lay eggs and reproduce en masse.

-
Pick flowers, fruits, and dropped leaves frequently to eliminate breeding sites.
-
Address drainage problems and improve soil quality to avoid boggy conditions.
-
Remove fallen, rotting fruits/veggies from nearby gardens right away.
-
Set out nematodes to parasitize fruit fly larvae in the soil before they mature.
-
Use drip or subsurface irrigation to keep foliage dry and less inviting.
-
Introduce natural predators like ladybugs which will feed on fruit fly eggs and larvae.
-
Avoid overcrowding vines to encourage airflow and discourage flies from lingering.
-
Use row covers on young vines to create a physical barrier against flies.
-
Position fans strategically to disrupt fruit fly activity with gentle breezes.
Stop fruit flies before they get started by making your garden as unappealing to them as possible. Consistent prevention helps reduce reliance on chemical treatments later.
Common Mistakes to Avoid When Managing Fruit Flies
It’s easy to make missteps when trying to banish fruit flies from your beloved vines. Be sure to avoid these common mistakes for the best results:

How to Grow Mandevilla
Indoors, mandevillas need curtain-filtered or bright indirect sunlight. Provide night temperatures of 60 to 65 °F and day temperatures above 70 °F. Plant in a mixture of equal parts peat moss, potting mix and builder’s sand. In spring and summer, feed every two weeks with a fertilizer high in phosphorus such as 10-20-10.
Outdoors, grow mandevillas in partial shade. They need rich, well-drained, sandy soil with humus added. Provide a frame, trellis or stake for support. Pinch young plants to induce bushiness.
Since 45 to 50 °F is the minimum temperature that can be tolerated by mandevilla, plants should be moved indoors for the winter. Before bringing them indoors, examine them carefully for pests. Look under the leaves, in the leaf axils, and in every conceivable nook and cranny for insects and their eggs. Remove any diseased or dead leaves by hand. Insect-infested plants can be doused with a forceful spray of water to dislodge the pests, or you can use insecticidal soaps or other appropriate insecticides labeled for use on your plant. You may have to prune some of the plant to compensate for any root loss.
Move the plants to a lighted location where the temperature is above 45 to 50 °F. Reduce the frequency of watering to coincide with the plants’ rest periods induced by the cooler temperatures and reduced light.
In late winter or early spring before growth begins, prune by removing old, crowded stems and shortening others. Even if mandevilla is pruned almost to the ground, it will bloom the same summer on the new shoots, which develop from the base of the plants.
Mandevilla ‘Alice du Pont’ is a woody, twining evergreen vine. It grows to a height of 20 feet but is much shorter when grown in a container. The leaves are dark green, glossy, oval and 3 to 8 inches long. Clusters of pure pink, flared, trumpet-shaped, 2- to 4- inch flowers appear among the leaves, spring through fall. Even very small plants in 4-inch pots will bloom. This cultivar grows well in hanging baskets. Pinch off tips of new stems to induce dense growth.
Mandevilla ‘Laxa’ or Chilean jasmine (although it is native to Argentina) is a climbing, woody, deciduous vine. It grows to 15 feet. Leaves are opposite, oblong or heart-shaped at the base. They are 2 to 6 inches long, thin and dark green with gray-green undersides. Clustered summer flowers are white, 2 inches across and trumpet-shaped with a powerful gardenia-like fragrance. Provide rich soil. If the plant becomes badly tangled, cut it to the ground in winter. It will bloom on the new growth. Roots are hardy to about 5 °F.
Mandevilla ‘Splendens’ is an evergreen similar to ‘Alice du Pont’, with the same bloom period. The leaves are narrow, pointed and 3 to 8 inches long. The trumpet-shaped flowers are 2 to 4 inches across, pale pink when they open, with rose-pink eyes. As the flowers age, their color deepens to rose. The stems of M. ‘Splendens’ reach 10 to 15 feet in length.
- ‘Red Riding Hood’ has deep red flowers.
- ‘Summer Snow’ has sparkling white 3- to 4- inch flowers against dark glossy foliage.
- ‘Yellow’ has wide, bright yellow flowers. They are lower growing and shrubbier than the species and superb in hanging baskets.
The most common pests are mealybugs, scales, whiteflies and red spider mites.
