Baby box elder bugs, belonging to the family of boxelder bugs, are immature stages of the insects that share a close relationship with maple trees, elder trees, and ash trees. These bugs, known for their small size and distinct reddish-orange coloration, are often found clustered together on the leaves of their host trees, feeding on sap and causing damage to the foliage.

Box Elder Bug Management: A Comprehensive Guide
Box elder bugs, also known as elder bugs, are small, harmless insects that often become a nuisance pest during the fall when they seek shelter indoors. Their distinctive black and orange markings and close association with box elder trees have made them a familiar sight, especially in regions with abundant box elder populations.
These insects derive their name from their habit of congregating on and feeding on the seeds of Acer negundo, commonly known as the box elder tree. Box elder trees are ubiquitous in North America, providing ample nesting and feeding grounds for these bugs. During the summer months, they can be found in large numbers on the undersides of leaves, feasting on the tree’s sugary sap.
Habitat and Associated Entities
Box elder bugs, Boisea trivittata, are named for their strong association with box elder trees (Acer negundo). These trees, known for their distinctive compound leaves and winged seeds, provide box elder bugs with their primary food source and habitat.
The bugs feed primarily on the sap from box elder leaves and seeds, but they may also feed on other trees and plants, including maple, ash, and oak. In forests and woodlands, where box elder trees are common, box elder bugs are often found in large numbers. They aggregate on tree trunks, branches, and leaves, seeking shelter and feeding opportunities.
Additional Points:
- Box elder bugs are not limited to box elder trees. They may also be found in forests and woodlands that do not contain box elder trees.
- While box elder bugs prefer box elder trees, they can adapt to other trees and plants.
- The bugs are most active during the day, but they may also be seen at night.
- Box elder bugs are not considered a serious pest, but they can be a nuisance when they congregate in large numbers.
- The bugs are not known to transmit diseases to humans or animals.
Life Cycle and Behavior of Box Elder Bugs
Box elder bugs undergo a complete metamorphosis, passing through distinct stages of development: egg, nymph, and adult. Their life cycle begins in the spring when females lay clusters of eggs on the leaves or bark of box elder trees. These eggs overwinter and hatch into tiny nymphs in the early summer.
Nymphs resemble adult box elder bugs but lack fully developed wings. As they mature, they go through five instars, molting their exoskeleton with each stage. Each instar lasts about a week, and the nymphs gradually develop longer wings and darker coloration.
By late summer, the nymphs have transformed into hard-shelled adults. Adults are typically black with bright red markings. They gregariously gather on the sunny sides of buildings, particularly in the fall as they seek shelter from the cold. They overwinter as adults in protected areas, such as under loose bark, in cracks, or in attics.
Seasonal Patterns
Box elder bugs are most active during the summer and fall. They feed on the sap of box elder trees, but can also be found on other trees, including maple, ash, and elm. During the winter, they enter diapause, a state of dormancy, and remain inactive until warmer temperatures return.
Management Strategies for Box Elder Bugs
Box elder bugs, despite their nuisance nature, can be effectively managed with a combination of preventive measures and targeted treatments.
Preventative Measures
The key to successful management lies in preventing box elder bugs from entering your home in the first place. Here are some simple steps you can take:
-
Seal Cracks and Crevices: Inspect your home’s exterior for any cracks or gaps around windows, doors, and pipes. These openings serve as entry points for box elder bugs. Use caulk or weatherstripping to seal them effectively.
-
Remove Egg Clusters: During spring and summer, box elder bugs lay their eggs in clusters on the undersides of box elder tree leaves. Regularly check your trees and remove any visible egg clusters to prevent the population from increasing.
-
Trim Tree Branches: If possible, trim branches of box elder trees that hang close to your home. This action discourages bugs from making the short journey to your walls.
Insecticides and Their Application
In cases where preventive measures alone are insufficient, targeted insecticide treatments may be necessary. Choose products specifically designed for box elder bug control and follow the instructions carefully.
-
Pyrethroids: Pyrethroids are a common type of insecticide used to control box elder bugs. They act by disrupting the bug’s nervous system, causing paralysis and eventually death. Apply these insecticides around entry points or directly to the bugs themselves.
-
Neonicotinoids: Neonicotinoids are another effective class of insecticides that work by interfering with the bug’s feeding habits. They are available in both liquid and granular formulations and can be applied to the soil or directly to the bugs.
When applying insecticides, always wear protective gear and avoid contact with your skin or eyes. Follow safety precautions and dispose of empty containers according to the manufacturer’s instructions.
Physical Characteristics and Effects
Distinct Appearance: Box elder bugs are easily recognizable thanks to their unique appearance. They measure about half an inch in size and have an oval-shaped body. Their head and thorax are bright red, while their wings have a black, lace-like pattern.
Pest Status: Despite their striking coloration, box elder bugs are considered nuisance pests. They do not feed on or damage property but can become a nuisance when they congregate in large numbers.
Low Toxicity: Fortunately, box elder bugs pose minimal risk to humans and pets. They are not known to transmit diseases and are generally considered non-toxic. However, their droppings can leave behind stains on fabrics and surfaces. Additionally, some people may experience mild allergic reactions, such as sneezing or watery eyes, when exposed to large numbers of these bugs.
