The bottle should have an extensive label--it opens like a booklet; have to pull off a corner of the label--it will say something like "open here for complete directions". Different concentrations depending on the particular pest and area being sprayed. I use 5 oz per gallon, which is on the high end, but is wat is indicated when spraying a house to kill pest bugs, as compared with spraying for pest bugs on a produce cro, where the concentration recommended is much lower..
