Correct Quantity of Azadirachtin
I am willing to try the Neem Oil, but I would like to know the minimum amount of Azadirachtin (in ppm) necessary to do the deed. Some containers have 1500ppm, others have 1800ppm.
I have a moth/carpet beetle problem. Although I am not sure it is an infestation, they are certainly present and I would like a powerful effective insecticide (not repellant - insecticide!) while not exposing myself or my family to hazardous chemicals and carcinogens.
How much is enough or should I just buy anything as long as it says "100% Pure Neem Oil"?
Secondly, how many applications would be necessary (the problem is in several closets in the house) and how long will it take to know if it is working?
Is a dishwashing liquid or anti-bacterial liquid soap as effective (or better) than Castile Soap to use as an emulsifier or is there an advantage to using Castile Soap, which strikes me as too gentle as I have no plants to protect and really want to kill the larvae and eggs.
Your website mainly refers to using Neem Oil outdoors in gardens. Is it okay to use indoors on carpets, shelves, and baseboards?
