Leta talk about the L word.

We got the call for our first placements last night 2 boys 14 and 11. Right before they were dropped off, we were informed they had lice and were currently getting the first treatment.
What are some of the things you all have done to help treat lice without it looking like we are "shaming" the kids. I had a bad lice problem back in high school (friend group kept spreading it, one in the group never treated for 2 months) we had to bomb the house 2-3 times. Several trips to the laundry mat to wash all of our clothes and towels all at once. I want to keep the lice down to a minimum and get rid of them quick but I don't want to come off like we think they are dirty and trashy. Any tips?
