What I have to offer you is the most economical, and it's the safest.
1) Bag up stuffed animals in plastic and leave them in the plastic for 2 weeks.
2) Bedding does not have to be re-washed everyday. But it does help to gather it up and put it through the dryer. They don't like heat.
3) For the hair... Buy the cheap plastic shower caps that come in a package and are meant to be disposable. They work and I re-use them. Get the cheapest conditioner you can find. THICK kinds work best. Slather it all over the hair, put the shower cap on, and use rubber bands to make it tight. Now you can wear this thick goop for 2 hours at a time. Just do everyone and watch a movie together.
4) You need to repeat the conditioning treatment every day or at least, every other day for about 3-4 weeks. This will suffocate anything that hatches before it has a chance to grow big enough to lay new eggs. ALSO, it losens the glue the critters use to attatch to the hair. You comb and blow dry like crazy everytime you take it off. Obviously, you rinse it first LOL.
5) If there is anything in the house or on a coat or if something jumps on the kids while at school, these treatments will keep them from spreading because they suffocate.
6) At first, you need to go through the hair strand by strand picking out anything you see. This is much easier after these treatments, and most will blow out with a hair dryer.
The poisons they have on the market do NOT WORK. It's a waste of money and bad for the body.
Anything in the home will be starved out if it doesn't jump back on someone and even if it does, it's going to be suffocated.
The beauty of doing this my way.. I have been able to treat children in the past when their parents would not or could not get it handled. I could irradicate it for them without even going to their home. I haven't seen it in 6 years and I am ready to do it all again if or when it happens. You'll also love how soft your hair feels after fighting this battle for awhile :)
