With its broad-spectrum control, this product will effectively reduce pest activity such as flea beetles, fungus gnats, and cabbageworms within vegetables and ornamental garden plants.

Tools Needed
To apply Monterey Bug Buster-O, you will need to use a handheld pump sprayer, backpack sprayer, or agricultural sprayer.
How to Use
- Step 1: Determine how much Monterey Bug Buster-O to use by measuring the square footage of the treatment area. To do this, measure the length and width of the treatment area in feet then multiply them together (length X width = square footage). Dilute 1 to 1.4 fl. oz. of Monterey Bug Buster-O per gallon of water per 1,000 sq. ft. for all applications. Do not exceed the maximum application rates of 1.4 fl. oz. of product per 1,000 sq. ft.
- Step 2: Fill the sprayer with half the amount of water, add measured amount of Monterey Bug Buster-O, then add in the remaining half of water. Close the spray tank lid and shake until solution is mixed. Mix only enough for immediate use.
- Step 3: Spray the Monterey Bug Buster-O solution until foliage is throughly treated, but not to the point of runoff.
