Naphthalene should be placed outside the plastic bags. I usually have an aerated container I put them in, and then I place them around the boxes, especially cardboard boxes, to prevent pests from getting in or out.
If you don't like that idea, you can use another type pesticide called primethrin (comes from the chrysanthemum plant). It is considered to be less toxic, yet effective in killing the lice and nits.
The information I have indicates that a complete regimen to totally eradicate the vermin usually last 2 weeks.
You can also freeze the clothes for 8-10 days.
Here is a little bit of info from the University of MO Extension Service:
The life cycles of the three human lice are very similar. The "nits" (eggs) are cemented to hairs (Crab and head lice) or to fibers and seams of clothing (body louse). The eggs hatch in 8 to 10 days (at 80-85 degrees F). Eggs fail to hatch if they are exposed to temperatures lower than 70 degrees F for 7 to 9 days. The louse nymphs (immature) feed on the blood of their host and molt three times before developing into sexually mature adults. After mating, the females begin to deposit small numbers of eggs each day for 20 to 30 days. A female crab louse deposits a total of about 30 nits. Head lice deposit 50-100 nits and body lice deposit 275-300 nits. The entire life cycle requires 21 to 27 days, and the adults live for 35 to 40 days.
