If you are looking for a way to up your gardening game and give back to the Durham community, consider becoming an NC State Extension Master GardenerSM volunteer in Durham County. All applicants must attend one of the Information Sessions being offered in late August through September 2024. Classes begin in January 2025 and run for 17 weeks.
Master Gardener volunteers at work sharing their know-how in the community. Here, volunteers install a pollinator garden at a local library, answer the public’s gardening questions, and prepare plants they grew for their annual plant sale. These are just a few of the opportunities Master Gardener volunteers have to serve Durham County. (Image credit: Allie Mullin)

By far our most popular post of all time, this article, originally titled “What’s That Bug? Leaf-footed Bugs in the Garden,” first appeared on our blog in June 2015. With veggie season in full swing, it’s just the right time to revisit this piece on a common pest. Plus we’ve updated it with new photos and resources.

I work in a garden with a group of volunteers. The other day, a sharp-eyed person pointed out some bright orange-red bugs like these on the leaves of one of our potato plants.
Identifying Leaf-footed Bugs
These are the nymphs of the leaf-footed bug, a relative of stink bugs. Adult leaf-footed bugs are brown, with a flattened, leaf-shaped area on their hind legs. Both the nymphs and adults are pests that damage buds, flowers, fruits, and seeds. Leaf-footed bugs feed on many plants, including tomatoes, peaches, blueberries, beans, okra, and pecans. When these bugs feed on tomato fruit, they cause yellow, hardened spots to develop. Feeding on other fruits can cause brown spots to shriveled, misshapen fruits, depending on the number of bugs and the time the fruits are damaged.

Adult leaf-footed bugs overwinter in weedy areas or under mulch and debris. They lay eggs in a row on the undersides of leaves or on stems. Eggs hatch in 5-7 days, and nymphs mature in 25-30 days.
Adult leaf-footed bug.There are 7 known species of leaf-footed bugs in the southeastern US. Identification tip: One species common in our region, the eastern leaf-footed bug (Leptoglossus phyllopus), is chestnut brown in color and has a distinctive horizontal white stripe on its back.

Controlling Leaf-footed Bugs
Leaf-footed bugs and their stinkbug relatives are difficult to control, but scouting for these pests now will help keep populations from building up throughout the season. Removing the nymphs and adults by hand and dropping them into a container of soapy water is an effective means of control when populations are small. You may want to wear gloves when picking leaf-footed bugs from your plants – they do have an unpleasant smell. There are few organic pesticides that are effective on these bugs, but hand picking now and reducing places where the adults can overwinter will help keep next year’s population in check. If you choose to use an insecticide to control a large population of leaf-footed bugs, pyrethroids can be used carefully and as directed.1
Just a quick word of caution, though – some assassin bugs (they are beneficial insects) are also orange and can look similar to the leaf-footed bug nymphs shown above. For photos of assassin bugs, see the University of Kentucky Entomology website.2
Notes
1–Leaf-footed bugs are also susceptible to insecticidal soaps. According to NC State’s Plant Disease and Insect Clinic, pyrethroid pesticides labeled for use by homeowners are also toxic to fish, so avoid using around pools, ponds, and streams. Pyrethroids are also toxic to beneficial insects like bees.
2–Consider a biological control method. Beneficial insects that are natural predators of leaf-footed bugs include look-alike assassin bugs, tachinid flies, native parasitic wasps, and spiders. Birds also prey on leaf-footed bugs. Making your garden attractive to beneficials may help curb unwanted pest populations.
