Lice & Nits: How to Get Rid of Head Lice

Is it possible to prevent head lice?

It's not always so easy to prevent head lice 100% of the time since it is a common infestation. Whenever possible, do not share hats or head coverings. Also avoid sharing combs and brushes with other individuals, since it can be transferred this way. If exposed to another individual diagnosed with head lice, continue to check the hair for eggs or adult lice every couple of days, but do not treat unless head lice are discovered.

Should household sprays be used to kill adult lice?

No. Spraying the house is not recommended. Fumigants and room sprays can be toxic if inhaled.

Should I have a pest-control company spray my house to get rid of lice?

No. Vacuuming floors and furniture is sufficient to treat the house.

What is the prognosis of a head lice infestation?

Once diagnosed and treated effectively, the prognosis is excellent. Eradication is of course the goal, and occasionally retreatment and alternative treatments are needed. Always consult a health-care professional if one needs advice.
