You can see the nits with a black light. Black lights are cheap, you can usually buy a bar at Walmart for under $20 near the regular light bulbs. The adults can only live for about 2 days without food. (I just researched it, said 55 hours) So as long as you can get rid of the nits (eggs) you should be good. If you keep the black light, take easy child 2 into the bathroom when she arrives and turn off the lights and on the blacklight. It says lice lay up to 10 eggs a day, so she will be covered in nits if she has lice. If she has it, use the RID. It also said that lice prefer females to males, kids to adults, long hair to short and so on. So she fits the bill perfectly.
