I don’t know but me(27F) and my husband (27M) and our two kiddos under 8 took permethrin oct 11…. Still got new bumps here and there everyday…. And I was one depressed pissed off clean freak mom. Bleaching floors, washing our sheets everyday and vacuumed everything including my car and hubs truck. So the next week we took permethrin cream again. Then oral ivermectin couple days later, still got new bumps. Then this week oct 26 we all did permethrin again, and oral ivermectin. You never know because these suckers can be laying eggs who knows when. And we still have been getting new bumps lol. Today is only the what 3d day after this weeks treatment. Fucking exhausted…. Hoping it’s just the dead mites and post scabies. I just wanna fucking enjoy the holidays
