The insect in the photo appears to be a kissing bug, or at least a closely related assassin bug from the family Reduviidae. Kissing bugs typically have a long, narrow head, prominent antennae, dark wings, and reddish or orange markings along the edges of the abdomen. Several other assassin bugs can look similar, so identifying the exact species from a photograph alone can be difficult.

Assassin bugs use a sharp, piercing mouthpart to attack other insects, and many species can give humans an extremely painful defensive bite if they are trapped, handled, or accidentally pressed against the skin. Some assassin bugs are actually beneficial outdoors because they prey on garden pests, but they are definitely insects you should avoid picking up with bare hands.

Kissing bugs deserve extra attention because some species can carry the parasite responsible for Chagas disease. Importantly, the disease generally isn’t transmitted directly through the bite. Infection can occur when feces from an infected bug gets rubbed into the bite wound, eyes, mouth, or another break in the skin. Chagas disease is most strongly associated with Mexico, Central America, and South America, although kissing bug species also occur elsewhere.

If someone has been bitten, wash the area thoroughly with soap and water and avoid scratching it. Seek medical attention if there is significant swelling, trouble breathing, severe pain, fever, or other concerning symptoms. If you still have the insect, don’t crush it with bare hands—place it safely in a sealed container so an expert can identify it.

So this isn’t a bug I’d casually ignore indoors. It looks like an assassin bug, possibly a kissing bug, and the safest move is to avoid handling it and get the identification confirmed.
