They’re just redbugs or chiggers.. I get them every year. I’ve lived here in SC my whole life and I have to deal with em every year about this time (late spring/early summer). Do not scratch them ! otherwise, you’ll get a nasty spreading rash ……… use alcohol or hydrocortisone cream …….don’t scratch, I know it’s hard ! you’re daughter probably has the most sensitive skin, hence the worst reaction to the bites.
Unlike those of other insects, bed bug bites may sometimes appear in tight lines of multiple, small, red marks where multiple bed bugs have fed along an exposed area. Bed bug bites can cause itchiness. Initially, a victim may detect a slight burning sensation. The burning area then develops red bumps, known as papules or wheals (rash). In extreme cases, bites may swell dramatically or turn into blister-like skin inflammations.
