Boxelder bugs go through three stages of development: egg, nymph, and adult. When they hatch, they start as tiny, red or orange, teardrop-shaped insects. As they grow, they develop black coloration and transform into an oval shape. Fully grown, boxelder bugs reach about ½ inches long and are mostly black, with their red or orange markings appearing as a trim or outline.
These bugs are known for congregating in large groups. You'll often spot a mix of reddish-orange and black insects with reddish-orange outlines. The more nymphs around, the more you'll notice the red or orange color.
Key traits of boxelder bugs include:
Keep in mind that boxelder bugs can have slight color variations, adding to their unique look.

Boxelder bugs primarily feed on the seeds of female boxelder trees. They use their mouthparts to suck the juices from leaves, flowers, and fruit as well. While they prefer boxelder trees, they also feed on maple and ash trees.
Though boxelder bugs have piercing mouthparts capable of breaking the skin of fruit, they rarely bite humans. They're generally docile and not aggressive. However, if handled roughly, you might get a surprise “bite.” It’s best to avoid handling them too closely.
Boxelder bugs are mostly nuisance pests, but their presence can be frustrating. As temperatures drop, they gather on sunny sides of structures, seeking warmth, and often make their way indoors to overwinter. Once inside, they can quickly become a nuisance. Their droppings or body fluids can stain clothing, furniture, curtains, and walls—some stains are stubborn and tough to remove.
When boxelder bugs congregate outside, they find ways inside through gaps and cracks. Some common entry points include:
They can also fly inside, especially when they gather near exterior doors.

Boxelder bugs are attracted to yards with food sources like the seeds of boxelder, maple, or ash trees. While removing these trees would solve the problem, it's not always a practical or desired option. Boxelder bugs might also gather simply for warmth on sun-soaked surfaces in your yard.
The most effective way to prevent boxelder bugs from entering your home is routine exterior treatments. These treatments deter pests from settling on your exterior and finding their way inside. Fall is the ideal time to start pest control services, as this is when boxelder bugs—and many other pests—begin searching for winter hiding spots.
