Gardening enthusiasts and homeowners often face the challenge of dealing with leaf-footed bugs. These medium to large-sized insects are known for their leaf-like hind legs and their ability to cause damage to a variety of plants, such as tomatoes, peaches, blueberries, beans, okra, and pecans. They use their piercing-sucking mouthparts to feed on plant parts, particularly seeds, resulting in weakened or destroyed crops.
It’s essential to recognize and manage these pests to maintain a healthy garden. Luckily, there are several strategies one can employ to control their presence, making it easier to protect your plants from potential damage. In this article, we’ll explore different methods of getting rid of leaf-footed bugs and preventing their return.
From natural predators to barrier techniques, the following sections will provide thorough guidance on combating these garden nuisances. You’ll learn about various approaches you can use to create a more sustainable, bug-free garden, ensuring your plants continue to thrive and produce an abundance of beautiful fruits and vegetables.
Understanding Leaf-Footed Bugs
Life Cycle
Leaf-footed bugs pass through five nymphal stages before becoming adults. Their life cycle includes:
- Eggs: Golden brown, laid in a single row or chain on stems or leaf undersides.
- Nymphs: Develop through five stages, becoming more like adults in each stage.
- Adults: Brown with flattened, leaf-shaped hind leg expansions.
Identification
Distinguishing features of leaf-footed bugs are:
- Medium to large-sized insects
- Belong to the family Coreidae
- Leaf-like enlargements on hind legs
- Piercing-sucking mouthparts for feeding on plants
To better identify leaf-footed bugs, consider comparing these features:
Feature | Leaf-Footed Bug | Assassin Bug |
---|---|---|
Size and shape | Medium to large insects | Smaller and more slender |
Mouthparts | Piercing-sucking | Curved, beak-like |
Legs | Leaf-like enlargements on hind legs | Thin, with no leaf-like expansions |
Behavior | Pest – feeds on plants | Beneficial – feeds on other insect pests |
To distinguish between different leaf-footed bug species, look for unique characteristics. For example, the eastern leaf-footed bug (Leptoglossus phyllopus) has a white line across its wing backs.
By understanding the life cycle and identification of leaf-footed bugs, you can better manage them in your garden.
Damage Caused by Leaf-Footed Bugs
Leaf-footed bugs are garden pests that can cause significant damage to a variety of plants, fruits, and vegetables. These insects have piercing-sucking mouthparts which allow them to feed on plant seeds and other parts, particularly in fruiting vegetables, nuts, berries, and ornamentals (source).
Nymphs and adult leaf-footed bugs often target popular garden crops such as tomatoes, pomegranates, eggplants, and nuts (source). They are also known to damage other plants like peaches, blueberries, beans, okra, and pecans (source).
Infestations of leaf-footed bugs could lead to fruit drop, irregular fruit growth, and reduced crop yields (source).
In addition to the direct damage caused by feeding, these pests can also transmit diseases to plants, further exacerbating the harm done to crops and gardens (source).
Comparison Table: Damage caused by leaf-footed bugs
Plants Affected | Type of Damage |
---|---|
Tomatoes | Sucking plant fluids, causing fruit drop and reduced yields |
Pomegranates | Piercing seeds, causing fruit to split and deform |
Eggplants | Feeding on seeds, leading to irregular fruit growth |
Nuts | Damaging nut kernels, reducing crop quality |
Characteristics of leaf-footed bug damage:
- Irregular fruit growth
- Fruit drop
- Reduced crop yields
- Possible transmission of plant diseases
It is crucial for gardeners and farmers to identify and manage leaf-footed bug infestations as these pests can easily wreak havoc on both ornamental and fruit-bearing plants.
Strategies for Controlling Leaf-Footed Bugs
Organic and Chemical Treatments
- Neem oil: A natural pesticide that can be applied on the pests and their eggs.
- Insecticidal soap: Kills nymphs and adults on contact by targeting their soft bodies.
- Pyrethrin: A chemical pesticide that can be used sparingly on infested areas.
Pros:
- Effective against a range of garden pests.
- Less harmful to beneficial insects when used carefully.
Cons:
- Can harm beneficial insects and natural predators if overused.
- Some can leave harmful residues on fruits and vegetables.
Natural Predators and Beneficial Insects
- Assassin bugs: Feed on other insect pests, including leaf-footed bug nymphs.
- Spiders: Catch and consume a variety of garden pests.
- Birds: Attracted by seeds, feed on adult leaf-footed bugs and other pests.
Physical Removal Techniques
- Handpicking: Physically removing the bugs from plants and submerging them in soapy water.
- Row covers: Placing covers over plants, especially during spring when bugs lay cylindrical eggs.
Cultural Practices
- Weed control: Removing weeds to remove shelter and alternative host plants.
- Woodpile management: Eliminating woodpiles where bugs can overwinter, hiding in crevices.
Companion Planting
- Planting sunflowers, peppers, or watermelons to deter leaf-footed bugs from the main crops.
- Adding plants that attract beneficial insects to the garden.
Integrated Pest Management
- Combine multiple methods from physical removal, cultural practices, and companion planting.
- Limit the use of chemicals and pesticides to reduce harm to natural predators and beneficial insects.
Method | Ease of use | Effectiveness | Impact on Environment |
---|---|---|---|
Organic treatments | Medium | High | Low-Medium |
Natural predators | Easy | Medium | Low |
Physical removal | Medium-Hard | Medium | Low |
Cultural practices | Medium | Medium | Low |
Companion planting | Easy | Medium | Low |
Integrated pest management | Medium | High | Low |
When dealing with leaf-footed bugs, it’s essential to use a combination of methods to control their populations and minimize their impact on your garden. Adjust your strategy based on the severity of the infestation, your location, and the type of plants you grow for the best results.

Nymphs and adults of both stink bugs and leaffooted bugs suck juices from green fruit leaving a puncture which later may become surrounded by a discolored zone due to invasion of secondary pathogens. Stink bug feeding punctures are often surrounded with a lightened, sometimes depressed, blotch beneath the fruit surface caused by the removal of cell contents and the enzymes injected by the bug. Leaffooted punctures may cause fruit to become distorted as they enlarge
Hi Gale,
Thanks for this fascinating information.
I found one of these on my window in January. I live in Louisiana. It was almost as big as my thumb and I’ve never seen anything like it before. Other than the name, there is no other information I could find on it. It doesn’t look like any stink bug I’ve ever seen. Are they harmful to humans? I don’t have any fruit trees in my yard so don’t know what it would be feeding on. I’d appreciate any information you could give me on this thing. Thank you.
Big Legged Bugs in the genus Acanthocephala are harmless to humans. You may read more on BugGuide.
I accidentally leaned back on a pillow where one of these bugs was sitting and it stung me. I thought I had been stung by a wasp. It just left a red bump, like a mosquito bite but the sting sure was painful for a minute.
One of these ugly things landed on me. Of course I overreacted and flung it off. The dogs got excited at my reaction and naturally came to examine it. It sting my Chihuahua in the eye. I immediately killed the bug then iced her eye. She seems fine now. I’m in the Midwest, near Chicago.
I have an Acanthocephala declivis nymph on my patio. I just want to know if it bites or stings and whether it’s poisonous or not.
Not poisonous. We have not gotten any reports of anyone being bitten.
I have them on several plants. Tomatoes, fruit trees and sunflowers. How do we fight them organically?
We do not provide extermination advice. We would recommend hand-picking.
We just found tis large brown insect with a grey head on our back screen door. We hate to kill anything without knowing if it is an assassin bug. Love the story about “Pumpkin Bug”, but since we have no pumpkins we will assume that it wants our butternut squash.
Still we hate to kill such an interesting bug.
Thank you for the info!
We will return in the future! 🙂
As it just so happens, I just saw this bug for the first time on our back patio. One of my dogs gave it a sniff and then rubbed her face in the grass for a couple minutes. I have read elsewhere that they do sting. It is October and we actually have pumpkins on our front porch, so score one for Granny, I guess.
DOES THIS BUG BITE? I FIND THIS BUG, I HAVE SMASHED HIM TO AVOID THE BITE OF PAIN.
Possibly, but we have never received any reports of people being bitten.
Hello, I live in Orlando, Florida, and had this Leef Footed bug walking on my car yesterday.

Hi any recommendations on treating them. I had tried soap water, neem oil and hot pepper sprays nothing seem to affect them except removing them by hand and disposing them in the garbage
