Monterey Garden Insect Spray RTU is for residential use in home gardens, lawns and ornamentals. Not for use on plants being grown for sale or other commercial use, or for commercial seed production, or for research purposes.

Monterey Garden Insect Spray RTU is intended for control of worms (caterpillars) and other listed insects. Monterey Garden Insect Spray RTU does not significantly impact predatory beneficial insects, predatory mites, and spiders while controlling target pests. Susceptible insect pests may be observed on plants up to several hours after treatment, but will have ceased active feeding before being killed.


Apply uniformly to both upper and lower surfaces of plant foliage. (Shake well before use)


Apply when listed pests are present. Repeat applications may be made as indicated in the Home Gardens section. See your state extension service recommendations for treatment guidelines in your area.

On vegetables and fruit trees how close to harvest can I apply?

On most vegetables 1 day before harvest and the minimum on fruit trees is 7-14 days. Consult the label for the exact time.

How often do I spray and how far apart should the sprays be?

That depends on the level of infestation. On most vegetables and fruits up to 6 applications can be made per season. These are spaced at 7 day intervals or more. On ornamentals and lawns there are no restrictions.

How much do I use?

The proper mixture is 2 oz. (4 tablespoons) per gallon of water and apply thoroughly to the area to be treated. Spray foliage to the point of runoff. On vegetables do not use more than 3 gallons of spray (6 oz.) per 1,000 sq. ft.

What about fruit trees for borers control?

It works excellent on these insects that get into stone fruit. Apply at 7 day intervals throughout the infestation period.

What about lawns?

Armyworms and sod webworms are a big problem in some areas. This is the product for you. Apply 6 oz. in 3 gallons of water per 1,000 square feet. Do Not water and mow the lawn for 24 hours after the application.

What about fire ants?

Monterey Garden Insect Spray can be used to control fire ants as an individual mound treatment. Apply 2 oz. per gallon of water in a water can or similar devise. Apply 1-2 gallons of this mixture per mound. Apply 10% around the mound and the remainder onto it. Do not disturb the mound before treatment. For best results, apply following a recent rainfall when temperatures are between 65-85 ºF.
