Day 6 of no evidence of live bug activity. Daughter slept in her bed again last night and woke up completely bite free today. Nonetheless, she asked me to dry her bedding and spray her bed with Cirkil again just to be safe. PCO perfectly fine with that. He'll be back in a week to reinspect.
It's too early to declare a victory yet but wow, I feel good today.
Keep the faith!
