How to stop kids scratching bug bites raw

Children mount stronger immune reactions to bite proteins and have less impulse control to resist scratching. They also scratch in their sleep, which is when most of the damage happens and when nobody is supervising.

The clinical consequence shows up a few days later: a scabbed, weeping bite, sometimes with the honey-coloured crust of impetigo. At that stage you are treating an infection rather than an itch.

Short fingernails do more than any lecture. Nails kept short and clean reduce both trauma and bacterial load.

A simple adhesive dressing over a bite hides it from wandering fingers and stops nails reaching skin. For a child who scratches through anything, cotton mittens at night are not undignified — they are the difference between a fading bite and a scar.

Cold flannels help while they are held on. They also give the child something to do with their hands, which is half the battle.

Everything above manages a problem that a fast intervention prevents. A device that ends the itch in seconds removes the reason to scratch at all, which is why it moved to the top of my own kit.

With children, explain the sensation before using anything warm on skin. Demonstrate it on your own arm at the child setting first. A child who understands what is about to happen will cooperate; a surprised child will not let you near them again.

Treat every visible bite before pyjamas, not after lights out. Cool the room — warmth intensifies itch. Long, light cotton sleeves reduce sleep-scratching. If a child has many bites and a strong reaction, a paediatric antihistamine at bedtime is reasonable, but check dosing with a pharmacist for age and weight.

Spreading redness, warmth, pus, fever, or a bite that is worse on day three than day one all warrant a clinical look. So does any bite the child cannot leave alone despite treatment — sometimes that indicates a reaction rather than plain nuisance itch.
