The texts provided do not specify any suggestions made by Erin to get rid of a lice outbreak. Instead, they discuss the use of lice in what appears to be a scientific or experimental context.
The text does not specify Erin's suggestion to get rid of the lice outbreak. However, based on the context provided, it is clear that the lice are being deliberately placed on certain plants by Claire and are being moved or protected in a box.
There is no mention of any specific measures suggested by Erin or any characters to eliminate the lice outbreak. Instead, the provided texts suggest a controlled use of lice potentially for scientific research or as part of an experiment, rather than an actual outbreak in a traditional sense that needs to be treated.
The mention of antifungal cream for ringworm, the description of the types of lice, and historical research on lice and human evolution provide a background on general lice treatment and importance, but do not give us Erin's specific suggestion for handling an outbreak. If Erin is indeed a character in the narrative, her proposed solution is not included in the text excerpts that have been provided.
