Head lice are most active at night. They can cause such intense itching that your child could lose sleep over it. It's uncomfortable, but lice won't make you sick. They don't spread disease and they're not a sign that you're dirty.
Symptoms. You don't usually start experiencing scalp itching when lice first arrive in your hair. You may not experience itching until about 4 to 6 weeks after lice exposure. This is because the lice take time to multiply and cause symptoms of itchiness.
Body lice generally are found on clothing and bedding used by infested people. Sometimes body lice are be seen on the body when they feed. Body lice eggs usually are seen in the seams of clothing or on bedding. Occasionally eggs are attached to body hair.
A tickling sensation in the scalp
Not everyone feels lice moving around on their scalp, but some people do. Dr. Garcia says that most of her patients say they “don't feel anything,” but others may get a creepy, tickling sensation as lice move around their head.
Considering the life cycle of lice and nits, it's possible to have live lice on a piece of bedding or pillow for up to 13 days. If a louse is without a host for 1-2 days, it will die. However, it can still lay eggs during that time.
Head lice survive less than one or two days if they fall off the scalp and cannot feed. Head lice eggs (nits) cannot hatch and usually die within a week if they do not remain under ideal conditions of heat and humidity similar to those found close to the human scalp.
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.
Common signs and symptoms of lice include: Intense itching on the scalp, body or in the genital area. A tickling feeling from movement of hair. The presence of lice on your scalp, body, clothing, or pubic or other body hair.
Typically, 10–15 head lice are found. The number of lice often depends on personal hygiene, for example, how often the person bathes, shampoos, or changes and washes his/her clothing.
Head-to-head contact with an already infested person is the most common way to get head lice. Head-to-head contact is common during play at school, at home, and elsewhere (sports activities, playground, slumber parties, camp). Although uncommon, head lice can be spread by sharing clothing or belongings.
Bedbugs are bigger than lice, about the size of an apple seed, while lice are about the size of a sesame seed. Bedbugs have flat, oval bodies, while lice are more oblong in shape. Bedbugs are brown, while lice are usually transparent, white, or yellow. Once lice fill with blood, they will become a brown color.
Coloration is an important differentiator since bed bugs are brownish-red or mahogany colored, while lice are somewhat light whitish or gray in color. Shape: While bed bugs have flat, oval bodies, lice are oblong.
Adult lice can't live longer than 24 hours or so on nonhuman surfaces like carpets, hardwood floors, clothing, furniture, sports helmets, headphones, or hair accessories. However, if you have identified lice in your home, isolate and wash those items and areas within at least 72 hours.
They're Easy to Spot
Although lice and their nits are small, you can see them with the naked eye. They can be white, brown, or dark gray. You're more likely to find them in the hair at the back of your neck or behind your ears. The nits are round or oval specks that are tightly stuck to hairs near the scalp.
A louse goes through three stages: Eggs that hatch after 6 to 9 days. Nymphs, immature forms of the louse that become mature adults after 9 to 12 days. Adult lice, which can live for 3 to 4 weeks.
Vinegar contains properties that kill and get rid of nits and lice. This mixture should be applied directly to the whole scalp. Mix 1 cup of vinegar with 1 cup of warm water. Next, distribute this mixture onto the scalp and cover your hair with a hair cap.
The peak season for lice infestation is August through October and again in January. Head lice are tiny parasitic insects that feed on human blood. Lice come in three forms: nits (eggs), nymphs (baby lice), and adults. Nits are white or yellowish-brown and about the size of a poppy seed.
Reliable data on how many people get head lice each year in the United States are not available; however, an estimated 6 million to 12 million infestations occur each year in the United States among children 3 to 11 years of age.
Look for lice crawling on the scalp where the hair is parted or on the hair shaft. The lice will be dark in color and the size of a poppyseed. Look for nits near hair follicle about ¼ inch from scalp. Nits (eggs) will be white or yellowish-brown.
Body lice live in your clothing and bedding and travel to your skin several times a day to feed on blood. The most common sites for bites are around the neck, shoulders, armpits, waist and groin — places where clothing seams are most likely to touch skin.
If you see sesame-seed-shaped objects, those are the nits and lice, which can be brown or grey and stand out against the white paper towel. “The nits may look like they have tails that stick out the back,” says Faulkner.
Either washing done with a water temperature of at least 50 degrees C or drying is necessary to kill head lice and nits.
There is no need for special chemicals or detergents to kill the lice. You don't need any unusual equipment or special training. The primary weapon against these bugs is… heat.
Do not use a conditioner. It can keep the lice medicine from working. Rinse well with warm water and towel dry. Do not use the towel again until it has been laundered.
The shampoo, cream rinse, or spray kills the live lice on the head but may not kill the nits. While the nits don't need to be removed from the hair, some people use a comb to remove nits after using lice treatment because they don't like the look of nits in the hair.
