Head Lice Hatching Routine
One of the difficulties involved in treating a head lice infestation comes from not understanding the life cycle of these annoying but oddly fascinating little creatures; diminutive they may be, miniscule even, yet they can cause a lot of trouble in a very short time!
Fortunately the age of the internet has led to us being able to understand the way these creatures live their lives – and feats on our blood – much more readily thanks to the prevalence of highly detailed and illustrated websites that show us exactly what happens, where and when. Summarizing the head lice hatching point is essential to understand where we need to be, and what we need to do, to catch these pesky creatures in order that they do not spread out of control.
The head lice is distinct from the nit – a point many people are unaware of; the former is the living creature, the tiny wingless insect that crawls around in your hair and pierces the skin to suck up blood – while the latter is the egg of the adult, and is by far the most difficult part of the equation to deal with. Indeed, the nits are so small that they may easily be missed with the best of head lice combs, and as such demand attention above and beyond that given to the living creatures.
In any treatment regime – whether using the likes of Malathion or Permethrin head lice treatment, or even the controversial Lindane, or resorting to herbal remedies or the bizarre suffocation by mayonnaise ritual – understanding that there may have been nits missed in the first treatment is essential and understanding the life cycle – and where the hatching point is – is essential.
An adult louse lives for approximately one month, and in that time she lays around 200 nits – around six every day – and the nits remain as eggs, attached to our hair by a very clever natural glue, for about one week. Once hatched they become head lice nymphs, young lice that are rapidly – in one to two weeks – advanced to breeding adults, and the whole episode begins again.
Knowing that we have one week from laying to hatching means we need to keep an eye out for new born nymphs for that period of time after clearing the head of lice, and we then have a further week to get rid of them before they begin laying. This is why regular, thorough examination is the best way to prevent head lice, and why understanding the hatching routine is vital.
