Lice no. But their eggs, yes! One louse can lay 150 nits a month (normal lifetime). They hatch in about 10 days, depending on the climate. Nits need at least 82o F.; and 70% humidity to incubate. During the incubation time the respiratory passages of the louse shut whenever the nits are immersed in water and they can survive under water for over 24 hours.
