Insecticide For Lice

When you find yourself with lice, you might be tempted to go the “natural” route and try to “harvest” the eggs without physically washing them from your child’s body. I can tell you from experience that this will not work. Please don’t even attempt giving your children concentrated amounts of vinegar to drink while they swim in the tub. It will not work, and your children will hate you. Lice can be a nightmare. Just ask my daughter and her classmates. The school is treating the kids with pesticide, but I feel that prevention is the best way to fight head lice.

Insecticide For Lice

• Have the infested person put on clean clothing after treatment.
• If a few live lice are still found 8–12 hours after treatment, but are moving more slowly than before, do not retreat. The medicine may take longer to kill all the lice. Comb dead and any remaining live lice out of the hair using a fine–toothed nit comb.
• If, after 8–12 hours of treatment, no dead lice are found and lice seem as active as before, the medicine may not be working. Do not retreat until speaking with your health care provider; a different pediculicide may be necessary. If your health care provider recommends a different pediculicide, carefully follow the treatment instructions contained in the box or printed on the label.
• Nit (head lice egg) combs, often found in lice medicine packages, should be used to comb nits and lice from the hair shaft. Many flea combs made for cats and dogs are also effective.
• After each treatment, checking the hair and combing with a nit comb to remove nits and lice every 2–3 days may decrease the chance of self–reinfestation. Continue to check for 2–3 weeks to be sure all lice and nits are gone. Nit removal is not needed when treating with spinosad topical suspension.
• Retreatment is meant to kill any surviving hatched lice before they produce new eggs. For some drugs, retreatment is recommended routinely about a week after the first treatment (7–9 days, depending on the drug) and for others only if crawling lice are seen during this period. Retreatment with lindane shampoo is not recommended.

• Supplemental Measures: Head lice do not survive long if they fall off a person and cannot feed. You don’t need to spend a lot of time or money on housecleaning activities. Follow these steps to help avoid re–infestation by lice that have recently fallen off the hair or crawled onto clothing or furniture.

  1. 1. Machine wash and dry clothing, bed linens, and other items that the infested person wore or used during the 2 days before treatment using the hot water (130°F) laundry cycle and the high heat drying cycle. Clothing and items that are not washable can be dry–cleanedORsealed in a plastic bag and stored for 2 weeks.
     2. Soak combs and brushes in hot water (at least 130°F) for 5–10 minutes.
     3. Vacuum the floor and furniture, particularly where the infested person sat or lay. However, the risk of getting infested by a louse that has fallen onto a rug or carpet or furniture is very small. Head lice survive less than 1–2 days if they fall off a person and cannot feed; nits cannot hatch and usually die within a week if they are not kept at the same temperature as that found close to the human scalp. Spending much time and money on housecleaning activities is not necessary to avoid reinfestation by lice or nits that may have fallen off the head or crawled onto furniture or clothing.
     4. Do not use fumigant sprays; they can be toxic if inhaled or absorbed through the skin.

  Over-the-counter Medications

  Many head lice medications are available “Over-the-counter” without a prescription at a local drug store or pharmacy. Each Over-the-counter product approved by the FDA for the treatment of head lice contains one of the following active ingredients. Always follow the label instructions when administering these medications. If crawling lice are still seen after a full course of treatment contact your health care provider.

  1. Pyrethrins combined with piperonyl butoxide;
     Brand name products:
     A–200*, Pronto*, R&C*, Rid*, Triple X*. Pyrethrins are naturally occurring pyrethroid extracts from the chrysanthemum flower. Pyrethrins are safe and effective when used as directed. Pyrethrins can only kill live lice, not unhatched eggs (nits). A second treatment is recommended 9 to 10 days after the first treatment to kill any newly hatched lice before they can produce new eggs. Pyrethrins generally should not be used by persons who are allergic to chrysanthemums or ragweed. Pyrethrin is approved for use on children 2 years of age and older. The efficacy of pyrethrinsexternal icon may be reduced because of development of resistance, but the prevalence of resistance has not been well studied and is unknown. If crawling lice are still seen after a full course of treatment contact your health care provider.
  2. Permethrin lotion, 1%;
     Brand name product:
     Nix*. Permethrin is a synthetic pyrethroid similar to naturally occurring pyrethrins. Permethrin lotion 1% is approved by the FDA for the treatment of head lice. Permethrin is safe and effective when used as directed. Permethrin kills live lice but not unhatched eggs. Permethrin may continue to kill newly hatched lice for several days after treatment. A second treatment often is necessary on day 9 to kill any newly hatched lice before they can produce new eggs. Permethrin is approved for use on children 2 months of age and older.Resistance to 1% permethrin  has been reported, but its prevalence is unknown. If crawling lice are still seen after a full course of treatment contact your health care provider.

Insecticide For Lice

Lice are a common problem with kids and adults alike. They live in the hair and lay eggs that can be seen as white or gray dots on the scalp. They feed on blood and can cause itching, redness, and scaliness. For this reason, they can be difficult to get rid of. Luckily, there are insecticides available to help you get rid of lice. Here are some tips on how to use these insecticides effectively:

If you think your child has lice, treat them immediately with insecticide shampoo or lice treatment cream. You can also use these products on yourself if you’re an adult who has been exposed to lice recently (e.g., by touching someone who has them). This will kill any lice that are present at the time you begin treatment but won’t prevent new ones from hatching later so continue using this treatment for at least seven days after symptoms stop appearing (which usually means no more itching or redness).
