Is Pyrethrins Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Pyrethrins? Is Pyrethrins safe for nursing mother and child? Does Pyrethrins extracts into breast milk? Does Pyrethrins has any long term or short term side effects on infants? Can Pyrethrins influence milk supply or can Pyrethrins decrease milk supply in lactating mothers?

Because absorption after topical application is very limited, occasional pyrethrins and piperonyl butoxide use is acceptable in nursing mothers. Extensive exposure, such as from agricultural use or malaria control might have long-term health concerns because residues can be found in breastmilk.[1] Only water-miscible cream, gel or liquid products should be applied to the breast because ointments may expose the infant to high levels of mineral paraffins via licking.[2]
