Hi - My DD 14, had a weekend sleep over - first time with a nice but newish school friend. Came home covered in flea bites to ankles .. legs .. about 50 bites! Told me one dog / two cats .. at sleepover house all scratching and sleepover parent commented how .. ‘oh yes they do need to be treated’ .. I washed all her clothing on her return. But ! .. She has been invited back !!! She’s embarrassed (teenager) to show / tell her friend the extent of her bites .. What politely can she say ? I know the parent only to say a friendly hello / goodbye on drop off / pick up ... advice appreciated. Aibu to send daughter in a protective anti- flea suit??? ... itching as I post
