Directions For Use

It is a violation of Federal law to use this product in a manner inconsistent with its labeling.

Read all Directions for Use carefully before applying.

Notice: Shake well before use. Avoid freezing.


This product is intended to be mixed with water and applied as a coarse or low-pressure spray. Fill the tank of the sprayer with water to about 1/2 of the total spray volume required. Start agitation and add the required amount of product. Continue mixing and agitation while filling the spray tank to the required spray volume. Maintain sufficient agitation during the application to ensure uniformity of the spray. Prepare spray fresh for each use.


● This product may be applied as a general surface spray or a crack and crevice application. Applications may be made in and around poultry and livestock premises, including but not limited to poultry houses, beef and dairy barns, feedlots, stables, corrals and housing structures.

● This product may be used as a direct treatment to control Northern Fowl mites infesting poultry.

● Control is enhanced when interior and exterior perimeter applications are made in and around livestock and poultry structures. Normal sanitation practices of the structure consistent with good animal husbandry should be followed to enhance effectiveness of insect control agents.

● Lactating and non-lactating dairy and beef cattle, swine, sheep and poultry may be present at the time of premise treatment. Horses not intended for human consumption may also be present at the time of premise treatment.

● Cover or remove exposed feed and water from the area being treated.

● Do not use in milking rooms.

● Do not apply as a fog or space spray.




House flies (adults and larvae)

Stable flies

Little house flies

• 2 fl. oz. (60 mL) Elector PSP in 10 gallons of water will treat 5,000 - 10,000 ft2. Use enough water in a directed spray to contact flies and their resting surfaces. Spray thoroughly, but do not allow run-off to occur.

Darkling beetles

Hide beetles

• Use enough water to ensure thorough coverage of the area treated, especially litter, along feed and water lines, walls and support beams. Use a sprayer of appropriate design that is equipped to effectively apply low to moderate volumes of spray.

• Low volume spray: Up to 15 gallons of diluted spray applied to 20,000 ft2.

• Moderate volume spray: Up to 40 gallons of diluted spray applied to 20,000 ft2.

• 2 fl. oz. (60 mL) of product treats 5,000 ft2 (8 fl. oz. of product treats 20,000 ft2).

• For severe infestations, 4 fl. oz. of product may be used to treat 5,000 ft2 (16 fl. oz. treats 20,000 ft2).

Northern fowl mites (Ornithonyssus sylviarum)

• Dilute 3 fl. oz. of product in 10 gallons of water.

• Apply no more than 1 gallon of coarse spray per 100 birds to ensure adequate coverage, directed toward the vent area.

Poultry red mite (Dermanyssus gallinae)

• Dilute 2 fl. oz. of product in 5 gallons of water.

• This dilution treats 2,500 ft2.

Egg Producing Poultry

Northern Fowl Mites: Spray birds in cages (layers) or on the floor (layers/breeders) with a coarse spray. Use a sprayer of appropriate design that is equipped to effectively apply the spray. Ensure adequate coverage of the vent area of the bird with a direct saturation spray for optimum efficacy. Re-application may occur every 14 days as needed.

Poultry Red Mites: Apply to areas where red mites live: this includes areas between joints, cracks and crevices, under bent surfaces, the ends of metal bars, any place where two surfaces connect, and any place where dust can accumulate. Application to the exposed and unexposed areas is required to obtain a complete and thorough treatment. Ensure a uniform spray with enough pressure to penetrate cracks and crevices where red mites are located during the day to achieve the highest efficacy of the treatment.

Poultry Houses

House Flies (adults and larvae), Stable Flies and Little House Flies: Treat areas where flies rest: pay attention to side walls, the ends of buildings, upper sides of posts, crossbeams, and manure. Spray in early morning when flies are resting. Use enough water in a directed spray to contact flies and their resting surfaces thoroughly, but do not allow run-off to occur. Do not contaminate feedstuffs, water or watering and feeding equipment with premise treatment. Re-application may occur every 7 to 10 days as needed, or when fly populations reach nuisance levels.

Darkling Beetles and Hide Beetles: Apply to floor area, especially to litter around food and water lines and to walls and support beams, but do not allow run-off to occur. Application should also be made into cracks and crevices around insulation, and where pests have been seen or can find harborage. Reapply after each grow-out or sanitation procedure. Indoor control can be enhanced by making perimeter treatments to the outside of building foundations to prevent migrating adult beetles.

Livestock Housing

House Flies (adults and larvae), Stable Flies and Little House Flies: Apply to vertical and overhead surfaces where flies may congregate. Feeders, waterers and feedcarts should be covered before application to prevent contamination. Do not contaminate feedstuffs or water with premise treatment. Pay attention to animal areas including fence railings, alleyways, manure, stanchions, pipes, window and doors, and other areas where flies congregate. Spray in early morning when flies are resting. Re-application may occur every 7 to 10 days as needed, or when fly populations reach nuisance levels.


This product is a member of a unique class of insect control agents (spinosyns) with no pre-existing levels of resistance to any other insect control agents and can be rotated with all other classes, such as synthetic pyrethroids and organophosphates. House flies, stable flies, little house flies and other insects have demonstrated the ability to develop resistance to insect control products. Continual exposure of flies and other insects to a single class of insecticide may lead to the development of resistance to that class of insecticide. The following resistance management strategy will help ensure the prolonged usefulness of this product, as well as other conventional insecticides:

● Apply this product and other insect control agents only according to label directions.

● Do not use less than the labeled rate of any insect control product.

● Include multiple control tactics (cultural and/or biological controls) within an Integrated Pest Management Program.

● Rotate this product with other classes of insecticides (synthetic pyrethroid, organophosphate) during a fly season.

For advice concerning integrated pest management practices in relation to specific local conditions, consult resources in resistance management programs, your Cooperative Agricultural Extension Service, or your Elanco US Inc representative (800-428-4441).
