Tools Needed

To use Acephate 90% Prills, you will need to mix the product in a handheld sprayer or a professional spray rig for large volume applications. 

How to Use

Step 1: To figure out how much Acephate 90% Prills you need, you will need to determine the treatment area. To do this, multiply length x width to get the total square footage to be treated. Typically, an average treatment should be done at a rate of 0.76 oz. to 1.51 oz. (21.0 to 42.0 grams) per 1000 square feet in a gallon of water, depending on the desired concentration you'd want. For example, If you have a 2,000 square foot area to be treated at a 0.5% concentration, you would need 1.52 oz of Celero mixed with 2 gallons of water.

Step 2: Since Acephate 90% is a water-dispersible granule it is important to add the chemical to water. To mix, you will put water in your sprayer, then add the appropriate amount of chemical to the sprayer and shake it up until well mixed.

Step 3: Indoors (non-residential), spray the product in a low-pressure coarse spray inside cracks and crevices such as around windows, storage areas, baseboards, corners of rooms and closets, under and around dishwashers, sinks, refrigerators, stoves, and cabinets. Outdoors (non-residential), spray the product via coarse fan tip setting on soil 6 to 10 feet adjacent to the structure and height of 2 to 3 feet on the foundation. On turfgrass, it should only be used to treat fire ant or harvester ant mounds.

It is not meant for indoor residential use. Anytime it is used in commercial food and non-food areas, it should be strictly used as a spot and/or crack and crevice treatment.
