When a child scratches restlessly at bedtime or during the night, dry skin or eczema often come to mind first. Scabies and head lice are also possible causes, and because they are managed very differently, knowing how they look helps you describe things clearly to a doctor.
Why It Happens
Scabies is a skin infestation caused by microscopic mites that burrow into the top layer of skin. According to the CDC, the hallmark symptoms are intense itching that is often worse at night and a pimple-like rash. The itch is thought to come from an allergic-type reaction to the mites and their waste, so symptoms may not appear until several weeks, and up to about two months, after a first infestation. Head lice are different: they are insects that live in scalp hair. Scabies tends to spread through prolonged skin-to-skin contact, so it can move through households and child care groups.
How It Looks at Different Ages
In older children and adults, the rash often shows up between the fingers and on the wrists, armpits, and waistline. In infants and young children the pattern tends to differ: lesions are often concentrated on the hands, feet, and body folds, and can also involve the scalp, face, neck, palms, and soles, sometimes with small pustules on the palms and soles. Head lice, by contrast, mainly cause scalp itching and scratch marks behind the ears and at the back of the neck.
Home Care
If scabies is suspected, having a clinician confirm it comes first rather than choosing products on your own. The CDC describes 5% permethrin cream applied from the neck down and washed off after 8 to 14 hours. One application can be enough, but a second or further application about a week later is sometimes needed. Not every scabies medicine used in adults is suitable for children, so age-appropriate treatment matters. Household members who have had prolonged skin contact or shared bedding, towels, or clothing are generally treated at the same time, even without symptoms, because a newly exposed person can carry mites for weeks before itching begins. Recently used clothing, towels, and bedding can be washed in hot water and dried on high heat, and items that cannot be washed can be sealed in a plastic bag for at least 72 hours.
Common Parent Misconceptions
Many parents assume the treatment failed when itching lingers. In fact, itching often fades slowly over 2 to 3 weeks even after the mites are gone. If it continues 2 to 4 weeks after treatment, or new burrows and rash keep appearing, retreatment may be needed, so it’s worth going back to the clinician. Treating only the child while family members go untreated commonly leads to reinfestation. Scabies is also not a sign of poor hygiene. On school return, the CDC says children can generally return to child care or school the day after treatment, though individual programs may set their own rules.
Signs That Need Medical Care
Consider talking with a pediatrician if your child is losing sleep from scratching, has a pimple-like rash between the fingers or in skin folds, or if others at home are itchy too. Scratched areas that become swollen, warm, or filled with pus may signal a secondary bacterial infection and warrant a visit. If a child develops fever with unusual sleepiness or a rash that spreads quickly and is painful, seek urgent care or emergency care right away.
