Fewer nits each day. To be safe we did a cetaphil nuvo treatment on wed night, 7/13. Combed it out and found no live bugs. Thursday morning saw a live bug and did another shampoo treatment early. More nitpicking over the weekend, saw live bugs Sat, Sun, Mon, more each day. Did wet combing the last two days. There aren't many nits but seem to be more bugs. What to do? All the bedding has been washed repeatedly.
OP what kind of comb are you using? You really need to use a GOOD professional comb, i.e. the Terminator.
A good comb out can take an hour to an hour and a half. You need to go very slowly.
You might not be seeing all the nits is my guess. You are missing them, and they are hatching into live bugs. The pesticide shampoo is often ineffective, so doing it twice doesn't really mean anything.

"Clark and a team of researchers examined the genes of lice from 32 sites in the U.S. and Canada and found that 99.6% of those tested in 2007-09 were genetically resistant to the pyrethrin- and permethrin-based chemicals most frequently used to treat them; those are the chemicals in such over-the-counter lice products as RID and Nix."
