Redrose, my sister works for a daycare center and has had lice several times and, unfortunately, it spread through the family and I did the mayo thing and the Clairol Cream Rinse and Conditioner and it worked for me. I put my pillow and bedspread in the dryer on hot heat each day and washed the sheets and blankets like every other day and someone told me to vacuum my mattress so did that as well. It took about
2 weeks of doing this and the little buggers disappeared. I hope you find something that can work for you with you being pregnant and that they go away quick.
