Identifying it in Maryland
A large dark bug, up to an inch, with a striped edge to the abdomen and a cone-shaped head. Bites are painless and often near the mouth or eye, which is where the name comes from — the insect is drawn to exhaled carbon dioxide.
Locally, the species most often confused with it are honey bee sting, mosquito bite, lone star tick bite — all of which are also recorded in Maryland.
Seek medical care if
- swelling of one eyelid with a nearby bite
- fever, fatigue or swollen glands in the weeks after
- a known kissing bug in the home — keep the insect for identification
What else it could be in Maryland
These are recorded in Maryland too and are the ones most often confused with it here. The differences below are the ones that actually separate them.
| Kissing bug bite | Mosquito bite | Bed bug bite | |
|---|---|---|---|
| Pattern | clusters, often on the face near the lips or eyes | single bumps scattered over exposed skin | lines or zigzags of three or more — the classic "breakfast, lunch and dinner" |
| Where on body | face, lips, eyelids | ankles, lower legs, arms | arms, shoulders, neck |
| Appears | painless at the time; bumps noticed on waking | within minutes | hours to several days — many people notice nothing on the first night |

Season in Maryland specifically
Records in Maryland concentrate in June to August, which is what local sighting data shows rather than a national average — seasonality shifts substantially with latitude. The general bite season in Maryland runs April to October.
Because crevices in older or rural housing, chicken coops, dog kennels, woodpiles — southern states, exposure in Maryland tends to be concentrated in specific places rather than spread evenly — which is why a bite history ("where were you in the 24 hours before?") narrows the answer faster than the appearance of the mark.
Care
- wash the area
- do not crush the insect against skin — the parasite is in its faeces, not its bite
- keep the bug in a sealed container if you find one; state health departments will identify it
Avoiding them in Maryland
- seal cracks around windows, doors and foundations
- move woodpiles and kennels away from the house
- outdoor lights away from doors — they attract the bugs at night
