Thanks again guys. DH just called - it's done. She fussed a bit and said "leave my hair alone" but he said she wasn't upset, more indignant - can't blame her. Outside of the hair issue, she's also at that age that she doesn't want anyone cramping her style. lol! I can't tell you how adorable and amazing this child is - we are blessed with our 3 children. Absolutely blessed. DH described her hair now as "very very short". I'm getting myself prepared. She's lucky in that she has a beautiful face with huge blue eyes so I think her pretty feminine charm will shine through.

I'm gonna hug her and smile and laugh with her a lot this evening.
Florida_Mom, I'm feeling annoyed now as I was assured that lice only live for 24 hours outside of the scalp so that's all it took to 'smother' them in a bag (regarding toys, cushions, coats etc.) but it sounds like that could be the problem. Although the main issue is still the phenomenal rate at which they breed on her head as opposed to the boys heads (or indeed mine or DH's - in all this time DH hasn't had one outbreak and I've had two but it was easy to get shot of them on my head too).
I didn't know about the hairspray - I spray all our heads with a mixture of lavender and tea tree oil each day - apparently it repels the lice.
Because of the belief that they couldn't survive more than 24 hours outside of the scalp I had not had the house professionally fumugated as Lisa_M Suggested but I'm going to arrange it now if they'll do that for lice.
mommasita, thanks for such encouraging words. Katy Belle, bigmerle1966, barkley, Lisa_M, Florida_Mom, lovetoscrap, Erin1700, TEENEE and chris1gill - thanks a million.
The next month will be spent checking, irradicating, cleaning, boiling, fumugating, whatever it takes so that by end of June this house WILL (I'm determined) be lice-free and then, I hope and pray, that by the time DD turns 4 next March she'll have a luscious head of gorgeous lice-free hair once more.
I can't tell you all how much better I feel for having shared this and for having read the responses.
