I have no idea - I was planning on 2 tablespoon's in 3.3 gallons - I would only measure in ml if I was administering a specific medication that required use of a syringe. This is going in a sprayer.
I also wanted to add that for those who have been using Frontline/Fipronil for Any pest - DON'T !! Read the recall that occurred in Europe... https://en.wikipedia.org/wiki/2017_Fipronil_eggs_contamination
You are correct in reading the label for the Elector - but you miss the directions that say to dilute it ... So - actually - the Monterey Spray could stand to be diluted as well !!
Dilute 3 fl. oz. of product in 10 gallons of water. Spinosad concentration in the dilution: ~1035 ppm** = mg/L...
