Elm Seed Bug

Commonly found on elm trees; in late summer and fall, they often seek shelter inside buildings and homes.

Primarily feeds on elm seeds by piercing them with their mouthparts and sucking out the fluids.

They are active primarily in the spring and summer. During the winter, they enter diapause and seek out warm, dry crevices, often entering human dwellings.

They are considered a nuisance pest rather than a threat to human health or property. They do not bite or sting, but they can emit a foul odor when crushed and may stain surfaces with their droppings.
