Where possible, treat these with effective laundry.
Otherwise, treat fabrics with permethrin and use an aerosol bomb to
treat impervious surfaces.
NOTE:
The US Army no longer has mass delousing capability with louse powders.
There is no longer an effective pesticide labeled for this use, and the
necessary dispersal equipment is no longer in the inventory.
(2) Head louse and crab louse.
Effective insecticidal shampoos and ointments are available by
prescription for control of these pests, and should be used as directed.
When these are not available, the louse powder can be used,
although to be effective it must remain on the body at least 10 days, as it does not kill
the eggs.
Thoroughly treat the body areas affected.
Treat clothing and bedding preferably by effective laundering, or if
this is not possible, then with permethrin or aerosol bomb, as appropriate
d. Mass Delousing. Mass delousing procedures are quite likely to be the
method of choice in delousing large numbers of people such as would be found in:
Prisoner-of-war camps.
Displaced person camps.
Occupied cities.
Ports of embarkation and debarkation.
-- ATTENTION --
When typhus occurs in civilian communities under military
jurisdiction, the military commander should immediately assume
responsibility for the institution of appropriate control measures.
Mass delousing should be accomplished as soon as possible.
(1) Hand dusters.
When hand dusters are used, formation of delousing teams of 3 to 5
enlisted men, with a noncommissioned officer to direct the operation, has proven
effective.
