Yes It Works: Derbac M contains Malathion which is an effective treatment for lice including pubic lice and the eggs. You should read the instructions, use only as directed (product is flammable). Repeat the treatment in 7 - 10 days. All sexual contacts should be examined and treated if infested. Wash all clothes, bedding, towels in hot water/hot dryer or dry-clean.
