how to calculate how long you have lice & how to remove it?

The news has broken, and your kid has lice. We know the drill. You’re thinking how long have you had lice? How did this happen? How do I get rid of lice? We’re tackling the first question among many—how to calculate how long you have head lice.

The life cycle of lice, specifically the head louse (Pediculus humanus capitis), comprises three main stages: the egg (or nit), the nymph, and the adult louse. Here's a detailed overview of each stage:

1. Egg (Nit):

• Appearance: Lice eggs, or nits, are tiny, oval-shaped, and typically yellow or white. They are about the size of a knot in thread.
• Location: Nits are laid by the adult female louse and are attached firmly to the base of a hair shaft near the scalp with a glue-like substance.
• Duration: It takes about 7-10 days for the eggs to hatch. The exact time can vary slightly depending on the environmental conditions, such as temperature and humidity.

2. Nymph:

• Appearance: Nymphs look like smaller versions of adult lice. They are initially translucent but become more colored (grayish-white to tan) as they feed on blood.
• Development: After hatching, nymphs go through three molts over 7-10 days before they become adults. They must feed on blood to survive, which they obtain by biting the scalp.
• Duration: The nymph stage lasts approximately 9-12 days, during which the louse grows and sheds its exoskeleton (molts) three times.

3. Adult:

• Appearance: Adult lice are about the size of a sesame seed, with six legs and a tan to grayish-white color. They may appear darker in people with darker hair.
• Reproduction: Female lice are slightly larger than males and can lay about 6-10 eggs per day. They live close to the scalp to maintain their body temperature and have access to their food source.
• Lifespan: Adult lice can live for about 30 days on the human scalp. If removed from the scalp, they usually die within 1-2 days due to the lack of food (blood) and the proper temperature.

Key Points:

• Transmission: Lice spread mainly through direct head-to-head contact. They can also be transmitted through sharing personal items like hats, hairbrushes, and bedding, although this is less common.
• Infestation: An infestation of head lice is known as pediculosis. Itching and irritation from lice bites are common symptoms.

Prevention and Treatment:

• Regularly checking children’s hair, especially in schools and daycare centers.
• Using medicated shampoos and lotions designed to kill lice.
• Thoroughly cleaning personal items and surroundings to prevent re-infestation.

Understanding the life cycle of lice is crucial for effective treatment and prevention of infestations.

It is important to note, after the first successful lice generation, the females mate only one time and lay nits for the remainder of her lifespan. The louse lifespan is usually between 30-33 days, and females can lay up to 10 nits (eggs) a day! 

Calculating how long you have had lice:

Determining how long someone has had lice involves understanding the life cycle of lice and observing the stages present in the infestation. Here's a step-by-step guide to estimate the duration of a lice infestation:

1. Identify the Stages of Lice Present:

• Nits (Eggs): Check if there are unhatched nits attached to the hair shaft near the scalp. Nits are usually located within 1/4 inch of the scalp.
• Nymphs: Look for small, immature lice. Nymphs are smaller than adult lice and are less than 9 days old.
• Adult Lice: Presence of adult lice indicates that the infestation has been ongoing for at least a few weeks.

2. Assess the Development Stage of the Nits:

• Unhatched Nits: If you find unhatched nits, the infestation is likely to have started within the last 7-10 days since nits take about 7-10 days to hatch.
• Nits at Different Distances from the Scalp: Nits that are found further from the scalp might be hatched and empty, indicating that the lice have been present long enough for the hair to grow. Hair grows about 1 cm per month, so the distance of nits from the scalp can help estimate how long they have been there.

3. Evaluate the Number of Adult Lice:

• Few Adult Lice: If only a few adult lice are present, the infestation might be relatively recent (about 2-3 weeks old).
• Many Adult Lice: A larger number of adult lice suggests a longer infestation period, likely over a month.

Estimation Steps:

1. Examine Nits:

• If you find mostly unhatched nits close to the scalp, the infestation likely started within the past 7-10 days.
• If you find nits further from the scalp (more than 1/4 inch), estimate how far they are from the scalp to determine how long the hair has been growing since the eggs were laid. For example, nits 1 cm from the scalp suggest the infestation has been present for about a month.

2. Check for Nymphs and Adults:

• The presence of nymphs indicates that the infestation has been ongoing for at least a week or more.
• The presence of adult lice suggests that at least one full life cycle (approximately 3-4 weeks) has occurred.

3. Calculate Based on Observations:

• If you find a mix of nits, nymphs, and adult lice, consider that the infestation likely began more than a month ago.
• If you only find adult lice with few or no nymphs and nits, the infestation might be recent, but it’s rare to have only adults.

Example Calculation:

• Finding Nits and Adults: If you find nits about 0.5 cm from the scalp and several adult lice, you can estimate:
  • Nits at 0.5 cm suggest the eggs were laid about 2 weeks ago (since hair grows approximately 1 cm per month).
  • The presence of adults indicates that the lice have matured, which takes about 3 weeks.

        In this case, the infestation might have started approximately 3-4 weeks ago.

Conclusion:

By carefully examining the types and stages of lice present, you can estimate the duration of a lice infestation. If you're uncertain or if the infestation is severe, consulting a healthcare professional or a lice specialist can provide more accurate information and appropriate treatment options.
