Understanding Box Elder Bugs
Box elder bugs are small, harmless insects that are easily recognizable by their distinctive black and red markings. They are about half an inch long and have a flattened, oval-shaped body. They get their name from the box elder tree, which is their preferred food source.
What do box elder bugs look like?
- Color: Black with red lines along the edges of their bodies and wings.
- Shape: Flat and oval, like a small seed.
- Size: About half an inch long, similar to the size of a pencil eraser.
Where Do Box Elder Bugs Live? Preferred Habitats
Box elder bugs are native to North America and are found throughout the United States and Canada. They are particularly common in areas where box elder trees are abundant. These trees provide them with food and shelter, making them ideal habitats for these insects.
Box Elder Bug Habitats
- Box elder trees: As their name suggests, box elder bugs primarily live in and around box elder trees. They feed on the seeds, leaves, and flowers of these trees.
- Maple and ash trees: While box elder trees are their favorite, these bugs can also be found on other trees like maple and ash.
- Sunny areas: Box elder bugs are attracted to warm, sunny places. You’ll often find them congregating on south-facing walls and rocks.
- Homes and buildings: In the fall, box elder bugs seek shelter for the winter. They often find their way into homes and buildings through cracks and crevices.
The Box Elder Bug Life Cycle
Understanding the life cycle of box elder bugs can help us understand their behavior and how to manage them.
- Eggs: Female box elder bugs lay their eggs in the spring on the bark of box elder trees.
- Nymphs: The eggs hatch into nymphs, which are smaller versions of the adults but without wings. They go through several molts as they grow.
- Adults: By late summer, the nymphs develop into adults with wings. They continue to feed and mate throughout the fall.
- Overwintering: As temperatures drop, adult box elder bugs seek shelter to survive the winter. They often enter homes and buildings for this purpose.
Why Do Box Elder Bugs Come Inside?
Box elder bugs don’t actually want to live inside your home. They are simply looking for a warm, protected place to spend the winter. They are attracted to the warmth of your house and will often gather on sunny walls or windows.
Reasons for Home Invasion
- Warmth: Your house provides a cozy escape from the cold winter temperatures.
- Shelter: Cracks and crevices in your home offer protection from the elements and predators.
- Accidental Entry: Sometimes, box elder bugs simply wander inside by accident through open doors or windows.
Box Elder Bugs and Your Home
While box elder bugs are not harmful to humans or pets, they can be a nuisance. They don’t bite or sting, but they can release a foul-smelling liquid when crushed. Large numbers of them can also stain surfaces with their droppings.
Problems Caused by Box Elder Bugs
- Nuisance: Their presence in large numbers can be annoying and unsightly.
- Stains: Their droppings can stain walls, curtains, and furniture.
- Odor: When crushed, they release an unpleasant odor.
