My head was itching just reading this! Headlice happen, but if people refuse to get them treated then i think it's fair enough to either not let them come stay in your home, or at a minimum insist they bring their own pillow, hairbrush, comb etc & wear a hat at all times to minimise the risk of spreading to other people. Your DH needs to address this issue though, and perhaps threaten BM with informing the school, child services etc - in the UK not treating headlice is counted as neglect!

How often are SD15 and SS15 in your house?? I wouldn't let them in if they had lice and everyone's refusing to get rid of them. Why would parents want to let their kids continue to have lice??? How freaking bizarre!!!

Call the school. They don't allow kids to go to school with lice. Tell the nurse to go through with a comb like you suggested. Then, when they get sent home, make sure DH or BM has to deal with it!

But as for you and your kids, I have one word ... Listerine!!! We just had a discussion about this here -

This is what I wrote:

"But I looked up the listerine treatment online after reading that suggestion here. I tried it last night. Put it on their heads, wrapped them in plastic caps and left it on for 2 hours. Then they got in the shower, washed it with an apple cider vinegar/shampoo mix (I read vinegar helps loosen the eggs from the hair shaft) and then put a ton of coconut conditioner (I read lice don't like that smell) then had them comb and comb and comb with one of the metal nit combs.

From everything I've read, as long as you focus on treating the head and getting everything out of there, the house will be okay. Their sheets and everything are washed and mattresses sprayed so ...

I'm going to do the listerine treatment every Tuesday night for the next month. And they're using nothing but coconut scent from now on. Maybe have them rinse with listerine every once in a while for good measure. I read all of this will repel them and kind of makes the girls' heads lice-proof. I hope they're right because right now their heads are extremely lice-prone."

That was Tuesday night, the SDs hair still smells like listerine when it's wet. Woohoo! Maybe they're lice-proof!

OMG! Keep those skids away if they have lice.

BTW... my sister shaved her head when she caught lice. I think she was about 18. She looked just like my dad, lol. You have to be a very confident woman to pull off that look.

Lice definately suck. I found a great treatment myself, and it is finally offered as a generic!

Ovide can be perscribed by a doctor, it is a dilouted form of Malathion, a common pesticide.

It stinks, but it is worth it! We did not find dead lice, we found DISENTEGRATED lice. Eggs dead too fromt this stuff.

We tried almost everything, BM would not treat her daughter. We eventually got this stuff from the doctor and got one for BM too! For the woman who would not treat her daughter, even she did this treatment on herself. She kept crying to BF, "no one will help me, will you?" HIs answer was of course Hell No!.

It is sad that even if you treat someone on a regular basis, if they keep going back to an infested house, they will come back with it. My poor SD10 had it for 2 years before we found this. I brought home all kinds of remedies. We even called CPS twice! No can do, this state does not keep them out of school, they just send home a letter of how to get rid of them. Send them back the next day.

Good luck, it might be a long road.

One thing about lice that many people don't get is that it's a cycle. You can't treat it once or even twice and be done. Eggs hatch every seven days (I think I remember right from my own lice hell) so you have to continually pick nits for a good two weeks and check carefully even after that. I dont' think you can even depend on those combs they sell with kits. You have to pull the nits off with your fingernails each and every one at a time. I feel for you.

Tell your dh that his kids are not allowed into the house until they get checked by a registered nurse for the next several visits since they refuse you to do it. He is to take them there, If they are positive, they go back home until they are treated.
You treat your entire house for several weeks with the shampoos, I know its a headache.
My sd brought them over for 3 years! in a row! ss was easy cause when seh was positive, they would shave his hair off completley. So i decided, not only is she going to shampoo, cause thank god her mother did shampoo treatment with that lice thing...i was going to pluck ever hair i saw with an egg!!!! I spent 2 1/2 hours plucking one weekend. Suffice it to say, she was positive this year, she stayed home until they were dead before coming over. BUt the kids were more than happy to be checked.
Your ss BM is a psycho and i would get the school involved on this one. Cause its not only your house she is affecting, i'm sure sd is spreading it at school. That is how my sd would get recontaminated, by a school girl who' mom didn't believe in treating. Well they sent a letter home with the little girl barring her from school until she was treated
Will this start a fight with your dh...yup! is it worth, yup! its lice! Does your dh have it yet? If not make sure he gets a good dose!
p.s the third time it happened, bm accused me of giving it to her daughter! She doesn't even live with us! comes eow! and the following weekend she asked and kept asking sd is i had gottne it cause bm's house was infested:) I'm happy to say, i didn't! even while plucking her for 2 1/2 hours! Neither did my son or my husband. I decontaminated after she left and made everyone wash with lice shampoo for a few days after she left just to make sure.

Ahhhh lice...

We had six months of sheer lice hell with FIVE kids involved. BM would not treat or would undertreat, wouldn't nit pick so I spent hours and hours nit picking hair, washing clothes, beds. etc.

In the end, the two kids with the thickest hair ended up with short hair.

I partly blame the schools. They hang all their coats and stuff together. Some schools gave all kids garmet bags to put their coats, hats, etc in and it made a big difference.

Ladies, lice happens. Its not the kids fault, really. Deep breathes and relax. This too shall pass.

More like kids sharing EVERYTHING! Ack, you would think that they would dislike lice enough to start being careful but oh no. they never learn.

Watch your eye makeup.... I got a roaring eye infection from SD15, had to throw everything out and buy new. I told her to throw her's out, she didn't, reused it and got another infection. Fortunately, I hid my makeup after my first experience...

Teenagers.. God help us all.

EWWW, I'm going to have nightmares about lice from reading this. Lol. I wouldn't let that kid in my house and I'd tell DH to eat shit if he didn't listen to me.
