No, I would not. I would not have put pesticide on her either.
Please go to headlice.org and read the instructions there.
Simply washing her hair and then going through it thoroughly is sufficient. You can do this every evening or every other day. If you find nits with babies simply use your fingernails and slide the nit down the shaft of hair and drop it into a glass of water. If the nit is white then a baby has been born and you'll need to keep your eyes open for it.
You can use a head gear magnifying glass that you can buy at Hobby Lobby or some other craft store or you can use a magnifying glass that attaches to a table at a business supply like Staples.
I like the head gear the best because it is much closer to my eyes and I feel like I get better sight this way.
I make sure her hair is super wet and section it into several areas. Each of those is fastened and out of the way. Then I use a rat tail comb and take small sections and go from the root to the bottom of the hair and look for nits and bugs.
The bugs often look like a shadow that should not be there. They are easy to spot once you are used to this procedure.
Even when there is not a head lice scare I do this every weekend. If I find anything I make sure I repeat this every other day.
Her hair is almost waist length and thick. I can do her hair in about 20 minutes.
There are lots of natural removal sites on line. Just google them and you will find that there is so much that everyone thinks they have to do that is just old wives tales.
There is no disinfecting of a child care center. They can just take the pretend play clothes and other items such as stuffed animals, wash them, dry them, then set them aside for a week or so. Head lice don't do anything to disinfecting cleaners.
TO PREVENT ANY FUTURE INFESTATIONS YOU CAN GO BUY A SPRAY WATER BOTTLE AND SOME TEA TREE OIL. PUT A COUPLE OF DROPS OF THE TEA TREE OIL IN THE WATER BOTTLE THEN FILL IT UP.
USE THIS BOTTLE OF WATER EACH AND EVERY MORNING WHEN YOU "STYLE" EVERYONE'S HAIR. SPRAY IT ENOUGH TO GET IT DAMP.
Lice do not like Tea Tree Oil. It stinks. They also cannot stick their eggs to oily hair.
Tea Tree Oil is sold at Walmart in the Ethnic Hair Supplies. Ours is on the same isle as the hair color kits. The oil is on the 2nd row from the top in the middle.
it's only a couple of dollars for a small bottle that should last you at least a year.
