I have cleansed and bagged and vacuumed and stopped short of burning down the house and car to make sure I got them all. I've done this now 3 times in 3 weeks. I did read a lot too and most accounts say that the environmental treatment is less important that treating the actual problem on the heads because lice cannot survive for more than 24 hours without blood. But I wanted to be sure.
The house has never been this clean! The bonus was that I purged a lot too! Ha-ha. I was actually thinking of joining the 2013 things in 2013 thread.
I comb my DDs hair every 1/3 day too. It is such a hassle with her. The worst is that her hair is so fine that I have seen nits and small insects stay behind. So, when I comb her hair, I also inspect each small strand and take the insects and nits out by hand! If I don't, they just stay behind. I tried 5 different combs with the same results. It is enough to make me scream.
I really don't know how to handle the X wife's reluctance to comb out her daughters hair. On the one hand, I don't blame her; she works a heavy job and is a single mom. On the other hand, I wonder why the 14 year old brother can't comb his sister's hair and she (11) comb his. I actually suggested they do so.
I was thinking of letting the two of them read literature that say:
1) long hair hanging loose over shoulders is more likely to get lice - they both have long hair.
2) Combing is important or going through the hair often to pick nits.
I mean, they are old enough to take the reigns here and I can show them how.
