Florida is home to at least nine species of insects from the genus Leptoglossus, some of which possess “foliaceous hind tibiae,” but only Leptoglossus phyllopus has earned the common name “leaf-footed bug.” This insect, a close relative of the stink bug, plays a fascinating yet problematic role in gardens. The nymphs are bright orange, while the adults are brown with a distinct flattened, leaf-shaped structure on their hind legs. Unfortunately, both stages of the leaf-footed bug are notorious pests, causing significant damage to buds, flowers, fruits, and seeds.

These pests feed on a wide variety of plants, including tomatoes, peaches, blueberries, beans, okra, and sunflowers. Their feeding activity can cause yellow and brown spots, misshapen fruits, and shriveled produce, depending on the severity and timing of the infestation.
In the fall, leaf-footed bugs can gather on warm windowsills or home siding. They can sometimes find openings in homes and get inside, but they don’t cause any damage indoors and don’t deposit eggs. Adult leaf-footed bugs also seek shelter in weedy areas or beneath layers of mulch and debris. They lay their eggs in neat rows on the undersides of leaves or along stems, with eggs hatching within 5 to 7 days. The nymphs then mature in approximately 25 to 30 days, leading to a rapid increase in population.
Integrated Pest Management (IPM) strategies are highly effective for controlling leaf-footed bugs. IPM involves a combination of cultural, physical/mechanical, biological, and—when necessary—chemical control methods. Following the IPM triangle approach, gardeners can start with the least harmful methods (like cultural practices) and gradually escalate to chemical controls if needed, depending on the infestation threshold. Early scouting and intervention are crucial to preventing the population from escalating throughout the growing season.
Though there are only a few organic pesticides that effectively manage leaf-footed bugs, proactive steps like hand-picking and reducing overwintering sites can help curb their numbers in the following year. For larger infestations, homeowners might consider using pyrethroids, which should be applied according to the manufacturer’s instructions. Leaf-footed bugs are also susceptible to insecticidal soaps and other pyrethroid-based products available at most garden retailers.
A word of caution: Some beneficial insects, such as assassin bugs, resemble the orange nymphs of leaf-footed bugs. Be sure to correctly identify these insects to avoid harming species that are beneficial to your garden.

African violets (Saintpaulia ionantha) are beloved houseplants known for their vibrant blooms and ease of growth indoors. Since their introduction to the United States, they have become favorites among plant enthusiasts for their adaptability and stunning flowers, making them staples in homes and offices. African violets thrive in bright, indirect light and moderate temperatures, and they come in various flower colors, including pink, purple, white, and combinations of these hues. Here’s how to ensure your African violets thrive with proper watering, fertilizing, and propagation.
Watering
The quality of water is crucial for African violets. Use water that is safe for drinking, making sure it is at room temperature or slightly warmer to avoid causing yellow spots on the leaves. The watering needs of African violets vary based on soil mixture, drainage, light, temperature, and humidity. For example, clay pots require more frequent watering than plastic pots due to higher evaporation rates. Water your African violets when the soil surface is dry to the touch or if wilting is noticeable.
There are two methods to water African violets: top watering and bottom watering. For top watering, apply enough water to saturate the soil and discard any excess that drains out. For bottom watering, place the pot in a container with about an inch of water. Once the soil surface becomes moist, remove the pot, let it drain, and discard any remaining water. Self-watering pots are also an option, and you can create one by making a “water wick” from a material like a braided nylon stocking. Insert the wick into one of the pot’s drainage holes and ensure it reaches the bottom of a water reservoir. Whether you water from the top or bottom, avoid letting the plant sit in water.
Fertilizing
African violets benefit from regular feeding with water-soluble fertilizers like 20-20-20 or 15-30-15. Mix the fertilizer at one-fourth the recommended rate and apply it every time you water, ensuring the soil is moist before application. If your plant shows signs of needing nutrients, such as gradual loss of leaf color, reduced growth, and fewer flowers, fertilize and observe for ten days. Be careful not to over-fertilize, as this can result in tight centers and rusty-appearing new leaves.

Propagation
Propagating African violets is simple and can be done using leaf cuttings. Choose a healthy leaf from the middle of the plant, snap or cut it off, and trim the petiole (leaf stem) to about 1–1.5 inches. Insert the petiole into a propagation medium. Roots typically form at the petiole base within three to four weeks, new leaves appear three to four weeks and flowering occurs six to nine months later.
Additional Tips
When purchasing an African violet, it usually adapts well to its container for a while. Although these plants prefer a crowded environment, repotting them annually into lightweight potting media is advisable.
Maintaining sanitation is essential to prevent diseases. Ensure all pots, tools, and materials are clean before use. With proper care and attention, African violets can flourish, bringing beauty and joy to any indoor space. By following these guidelines on watering, fertilizing, and propagating, you can enjoy healthy and vibrant African violets in your home. for more information, contact your local Extension Office or click on the links below:
