@Reggers214 I got curious and bolstered my memory by finding the thread on HT ad skimming thru it.
Conclusion was it didn't work to repel or kill lice....I figure it left my RAM because it didn't work. I've use permethrin on lice since.
How to tell the difference @Lady of McCamley?
Is it easy to see the color difference(black vs red) with the naked eye?
Or is it mites on bird during day is NFM and mites on bird and roost at night is RRM?
I hope I never have to differentiate, have only had lice here(knock wood) but am very curious.
