Is a calico bug dangerous?

No. Calico bugs (boxelder bugs) do not bite, sting, spread disease, or cause structural damage. They are solely a nuisance due to their numbers and tendency to enter homes.

What attracts calico bugs to my house?

They are attracted to warm, sunny surfaces in autumn as they seek sheltered overwintering sites. The presence of female boxelder or maple trees (their food source) nearby is the primary attractant.

What's the difference between a calico bug and a ladybug?

They are unrelated. Ladybugs (ladybird beetles) are round, dome-shaped beetles, often considered beneficial. Calico bugs are true bugs (order Hemiptera), shield-shaped, and are plant feeders/nuisance pests.

Can I use 'calico bug' interchangeably with 'boxelder bug'?

Yes, in regions where the term is known, it refers specifically to the same insect (Boisea trivittata). However, 'boxelder bug' is the more universally recognized common name.
