What are Head Lice and nits?

Head lice and nits are very common in young children, especially those living with family members who have them. They don’t come from dirty hair; the pests are picked up through head-to-head contact!

Head lice can make your head feel:

  • itchy
  • like something is moving in your hair

Head lice are an annoying problem that can be difficult to treat. The sooner you notice them, the easier it will be for your child’s scalp and hair follicles to heal themselves without any damage being done. Make sure everyone in the house gets treated on day one so we don’t pass this nasty condition onto other family members or classmates!

What is Scabies?

It’s important to get scabies treated quickly because it can spread and cause other problems.

Scabies is an itchy skin condition caused by a tiny burrowing mite called Sarcoptes scabiei. Intense itching occurs in the area where these microscopic parasites live and breed, causing sores that can be very painful for your pet or even worse if scratched at night time when you’re asleep! These pests are contagious which means they have been known to spread quickly between family members who come into close physical contact often enough so as long as one person has an infestation then everyone will most likely get infected too- doctor’s recommend treatment of entire families before any more children become sick from this pesky pest!


Scabies signs and symptoms include:

  • Itching, often severe and usually worse at night
  • Thin, irregular burrow tracks made up of tiny blisters or bumps on your skin

The burrows or tracks typically appear in folds of skin. Though almost any part of the body may be involved, in adults and older children scabies is most often found:

  • Between the fingers
  • In the armpits
  • Around the waist
  • Along the insides of the wrists
  • On the inner elbows
  • On the soles of the feet
  • Around the breasts
  • Around the male genital area
  • On the buttocks
  • On the knees

In infants and young children, common sites of infestation usually include the:

  • Scalp
  • Palms of the hands
  • Soles of the feet
