You add the recommended dose of neem oil to warmish water, then add just enough liquid dish soap to dissolve the neem oil in the water. Then add the recommended number of drops of pyrethrum.i found difficult mix neem oil with water! i shook it as much as possbile but seemed like residues were formed! i hope it worked!
That combination will dehydrate, mess with, paralyze, smother and starve most insects.
