Nits are oval-shaped, tiny, and often mimic the appearance of dandruff. Withal, unlike dandruff, they are steadfastly cement to the hair shaft. This point lasts for approximately 7 to 9 days.
2. The Nymph Phase
Erstwhile the egg hatches, it release a houri. A nymph looks like a toy variation of an adult insect but is not yet capable of reproduction. Nymphs must give on rip forthwith to survive. Over the line of the adjacent 7 to 10 days, the houri undergoes three molting form, increase in sizing and maturate into a fully developed adult louse.
3. The Adult Phase
Once the insect reaches adulthood, it is ready to multiply. An adult female can lay up to 6 to 10 egg per day. Throughout her 30-day lifespan of louse, a individual female can create rafts of egg, which is why infestations can escalate speedily if not treated during the initial stages. Adult lice are approximately the sizing of a benny seed and are tan to grayish-white in color.
Factors Influencing Survival Outside the Host
A common misconception is that lice can live in carpeting, bedding, or furniture for weeks. In realism, caput lice are obligate parasites, meaning they necessitate human rip to survive. When they are separate from the warmth of the scalp, they become dried and starve quite rapidly.
| Condition | Calculate Survival Clip |
|---|---|
| On a human legion | Up to 30 days |
| On bedding/clothing (off-host) | 24 to 48 hour |
| In water (pools/baths) | Several hours |
