Welcome and Happy Dreading..
if you have a dozen eggs in your fridge do you worry about chickens ovrerpopulating your house?
do u see anything moving or just eggs
dont wotrry bout eggs if nothings alive
but might be a good idea to do 1 2 or 3 more treatments just to be sure nothing hatches
1 surviving female will reinfest once a females fertalized shes pregnant for life ..only having to mate once to keep producing children till she dies
9 days minumum ..3 treatments
u might want to consider licelifters in that case its not the cheapesat option but its the best
Welcome and Happy Dreading.
Always, Hippie Love
