Signs of Head Lice◀ Back To Blog
September 5, 2012
The yellow school buses are moving all around the Capital District today, as summer vacation is officially over. Most local students return to classes today to begin a fresh new year. Without hampering a new school year, Thomas Pest Services wanted to remind parents, September is National Lice Prevention Month. Unfortunately lice are a real issue, that we wanted Capital Region parents to be "in the know."
Head louse is a tiny, wingless parasitic insect that lives among human hairs and feeds on extremely small amounts of blood drawn from the scalp. Although they may sound gross, lice (the plural of louse) are a very common problem, especially for kids ages 3 years to 12 years (girls more often than boys).
Lice aren't dangerous and they don't spread disease, but they are contagious and can just be downright annoying. Their bites may cause a child's scalp to become itchy and inflamed, and persistent scratching may lead to skin irritation and even infection.
Signs of Head Lice:
Though very small, lice can be seen by the naked eye. What you or your doctor might see by thoroughly examining your child's head:
Lice eggs (called nits). These look like tiny yellow, tan, or brown dots before they hatch. Lice lay nits on hair shafts close to the scalp, where the temperature is perfect for keeping warm until they hatch. Nits look sort of like dandruff, only they can't be removed by brushing or shaking them off.
Unless the infestation is heavy, it's more common to see nits in a child's hair than it is to see live lice crawling on the scalp. Lice eggs hatch within 1 to 2 weeks after they're laid. After hatching, the remaining shell looks white or clear and continues to be firmly attached to the hair shaft. This is the stage when it's easiest to spot them, as the hair is growing longer and the egg shell is moving further away from the scalp.
Adult lice and nymphs (baby lice). The adult louse is no bigger than a sesame seed and is grayish-white or tan. Nymphs are smaller and become adult lice about 1 to 2 weeks after they hatch. Most lice feed on blood several times a day, but they can survive up to 2 days off the scalp.
Scratching. With lice bites come itching and scratching. This is actually due to a reaction to the saliva of lice. However, the itching may not always start right away — that depends on how sensitive your child's skin is to the lice. It can sometimes take weeks for kids with lice to start scratching. They may complain, though, of things moving around on or tickling their heads.
Small, red bumps or sores from scratching. For some kids, the irritation is mild; for others, a more bothersome rash may develop. Excessive scratching can lead to a bacterial infection (the skin would become red and tender and may have crusting and oozing along with swollen lymph glands). If your doctor thinks this is the case, he or she may treat the infection with an oral antibiotic.
You may be able to see the lice or nits by parting your child's hair into small sections and checking for lice and nits with a fine-tooth comb on the scalp, behind the ears, and around the nape of the neck (it's rare for them to be found on eyelashes or eyebrows).
A magnifying glass and bright light may help. But it can be tough to find a nymph or adult louse — often, there aren't many of them and they're able to move fast.
Thomas Pest Services receives many inquires in regards lice, however it is a public health matter. In honor of National Head Lice Prevention Month, we thought a short blog to helpful links would be beneficial if someone ever has questions or experiences lice. Return tomorrow to learn if lice are contiguous, how to prevent lice and treatments for lice.
