DS3 has a bad case of headlice - 2 weeks in and he is still rife with them. He rather likes the idea of his "little friends" (odd boy, I know) so in an attempt to put him off, we put one into one of those bug watcher contraptions you can buy children - a sort of plastic box with a magnifying glass incorporated.
Well, I was always under the impression headlice did not live long once separated from a source of human blood, but it is now 9 hours later and guess what? Ds's "little friend" (not a very little louse by the way but a bloody large fecker) is still wriggling away merrily inside his box. I have just googled and apparently they can live for 2 days off the head!
Just thought you all might like to know that.
