Uncertain—likely small arthropod bites, possibly mosquito or flea bites

The insect cannot be confirmed visually. Mosquitoes occur near standing water; fleas commonly inhabit pets, carpets, bedding, and upholstered furniture.

Mosquito females take blood meals, while males feed on nectar. Fleas consume blood from mammals or birds.

Bites may cause small, itchy, red bumps; clusters or lines can occur, especially with fleas or bed bugs. Skin reactions alone cannot reliably identify the cause.

Usually limited to itching and localized inflammation, but scratching can cause secondary infection. Mosquitoes and fleas can transmit pathogens in some regions; seek medical care for spreading redness, severe swelling, fever, breathing difficulty, or persistent symptoms.
