The Leaf-Footed Bug: Florida’s Misunderstood Garden Neighbor

Leaf-footed bugs are a common sight in Central Florida gardens and landscapes. These insects belong to the Coreidae family and are named for the distinctive, flattened, leaf-like enlargements found on their hind legs. Adults are typically 0.75 to 1 inch long with a narrow, brown body, and they are often mistaken for stink bugs due to their similar shape. There are nine species of leaf-footed bugs found in Florida, with the Florida leaf-footed bug (Acanthocephala femorata) being particularly common on citrus trees, roses, and native shrubs.

Fun Facts

  • They make noise: Leaf-footed bugs are conspicuous insects that make a buzzing sound when they fly.

  • They are social: These bugs often gather in colonies, sometimes appearing in large numbers on host plants.

  • They are not aggressive: Despite their intimidating appearance, leaf-footed bugs do not chase or swarm humans; they are generally just feeding on plants and minding their own business.

  • They have unique mouthparts: They belong to a guild of “suckers” that use hypodermic-like mouthparts to feed on plant juices.

  • Nymphs look different: The nymphs (young bugs) of some species, like the leaf-footed bug, are commonly mistaken for assassin bugs due to their similar appearance.

Not-So-Fun Facts

  • They damage crops: Leaf-footed bugs feed on a variety of plants, including tomatoes, cantaloupes, eggplants, and citrus, causing damage by inserting their mouthparts into the plant tissue.

  • They can be a nuisance indoors: During certain seasons, leaf-footed bugs may enter homes in search of shelter, becoming an unwelcome indoor presence.

  • They reproduce quickly: A single female can lay a significant number of eggs, leading to potential infestations if not managed.

  • They are hard to spot: Nymphs and adults can be difficult to detect until damage becomes visible, especially if they are feeding on the undersides of leaves.

What Attracts Leaf-Footed Bugs?

  • Host plants: Leaf-footed bugs are attracted to a variety of plants, including tomatoes, cantaloupes, eggplants, citrus trees, roses, and native shrubs.

  • Overwintering sites: Adults seek sheltered areas to overwinter, which can include the siding of homes, attics, and other protected spaces.

  • Moisture: High humidity and moisture can attract leaf-footed bugs, particularly when they are seeking shelter indoors.

  • Lack of natural predators: A reduction in native egg parasites and other natural enemies can lead to larger populations.

How to Repel Leaf-Footed Bugs

  • Handpicking: Manually removing bugs by hand is a very effective method for small infestations. Dispose of captured insects in a jar of soapy water.

  • Insecticidal soap: Spraying young nymphs with insecticidal soap can help eliminate them.

  • Neem oil: This natural pesticide can be used to control leaf-footed bugs in the vegetable garden.

  • Row covers: Using physical barriers like row covers can protect plants from infestation.

  • Trap crops: Planting trap crops like sunflowers or marigolds can attract leaf-footed bugs away from main crops.

  • Home exterior treatments: Treating the siding of your home with insecticides like Pest Away (mixed at 2 oz per gallon) can help prevent bugs from entering.

What Pest Control Companies Do (and Don’t Do)

What They Do:

  • Inspection and identification: Professionals can accurately identify leaf-footed bugs and assess the extent of an infestation.

  • Exterior barrier treatments: Companies often apply insecticide treatments around the foundation, doors, and windows of homes to prevent indoor intrusion.

  • Integrated Pest Management (IPM): Effective management often requires a variety of methods, including removing overwintering sites, weed host removal, and the use of row covers.

  • Ongoing monitoring: Pest control experts provide ongoing solutions to manage infestations and prevent returns.

What They Don’t Do (or Why DIY Might Be Better):

  • They don’t always guarantee elimination: Because leaf-footed bugs are widespread in Florida and have many host plants, complete elimination is often not feasible.

  • They may not treat outdoor gardens: Many pest control companies focus on interior home protection and may not offer extensive outdoor garden treatments for leaf-footed bugs, leaving it to homeowners to manage.

  • Chemical treatments can be overkill: For small gardens, manual removal and organic options like neem oil or insecticidal soap are often more practical and environmentally friendly than professional chemical applications.
