User Safety Requirements

Follow manufacturer’s instructions for cleaning/maintaining PPE. If no such instructions for washables exist, use detergent and hot water. Keep and wash PPE separately from other laundry. Discard clothing and other absorbent materials that have been drenched or heavily contaminated with this product’s concentrate. Do not reuse them.

User Safety Recommendations

Users should wash hands before eating, drinking, chewing gum, using tobacco, or using the toilet. Users should remove clothing/PPE immediately if pesticide gets inside.

Environmental Hazards

This product is toxic to aquatic organisms, including fish and invertebrates. Run-off from treated areas or deposition of spray droplets in water may be hazardous to fish and aquatic invertebrates.

Before making the first application in a season, it is advisable to consult with the state or tribal agency with primary responsibility for pesticide regulation to determine if other regulatory requirements exist. Do not apply over bodies of water (lakes, rivers, permanent streams, natural ponds, commercial fish ponds, swamps, marshes, or estuaries), except when necessary to target areas where adult mosquitoes are present, and weather conditions will facilitate movement of applied material away from the water in order to minimize incidental deposition into the water body. Do not contaminate bodies of water when disposing of equipment rinsate or wash waters.

This product is highly toxic to bees and other pollinating insects exposed to direct treatment or residues on blooming crops or weeds. Do not apply this product or allow it to drift to blooming crops or weeds if bees or other pollinating insects are foraging in the treatment area.

To Control Silverfish:

Spray bookcases.

To Control Ants:

Spray trails, nests, and points of entry. If surface application only is to be used, spray floors, walls, and other surfaces at a rate of 1 gallon Prozap Aqueous Fly Spray to 750 square feet of surface.

To Control Carpet Beetles:

Spray edges of carpeting under carpets and rugs. Make localized application to floor and baseboard. Spray Prozap Aqueous Fly Spray directly into cracks, closets, and infested areas of shelving. Repeat treatment as needed.

To Control Bed Bugs:

To Control Fleas and Brown Dog Ticks:

Thoroughly spray infested areas, pet beds, resting quarters, nearby cracks and crevices, along and behind baseboards, moldings, window and door frames, and localized areas of floor and floor covering with Prozap Aqueous Fly Spray. Fresh bedding should be placed in animal’s quarters following treatment. Concurrent treatment of animals with an approved insecticide is recommended. Repeat treatment as necessary.

To Control Clothes Moths:

Remove any infested articles from storage, brush thoroughly, and air several hours in sunlight, if possible. Apply Prozap Aqueous Fly Spray liberally to empty chests, closets, bureaus, and other storages, directing spray into cracks, joints, and crevices. After airing, infested articles may be treated lightly keeping nozzle at least 3 feet from fabric to avoid staining.

Space Spraying

Close door and windows and shut off ventilation systems. Apply Prozap Aqueous Fly Spray with a good machine adjusted to deliver a fine mist or fog. Direct the spray at an upward angle, distributing it uniformly throughout the entire area at a rate of 3 to 6 ounces per 1,000 cubic feet of space.

Use at a rate of 1 gallon to 20,000 to 40,000 cubic feet of space. Contact insects directly whenever possible.

On-animal Uses

To Protect Cattle and Horses from:

Horn Flies, House Flies, Mosquitoes, and Gnats:

Apply a light mist of Prozap Aqueous Fly Spray sufficient to wet the surface of the hair.

Stable Flies, Horse Flies, and Deer Flies:

Apply Prozap Aqueous Fly Spray at a rate of 2 ounces per adult cow or horse, sufficient to wet the hair thoroughly. Repeat treatment daily or at intervals necessary to give continued protection.

Sucking Lice:

Apply Prozap Aqueous Fly Spray to the infested areas of the animal using a stiff brush to get the spray to the base of the hair. Repeat every 2 or 3 weeks, as necessary.

Outdoor Mosquito Control

Apply Prozap Aqueous Fly Spray as a fine mist to thoroughly treat the entire area. For best results, treat when the wind velocity does not exceed 5 miles per hour (m.p.h.). Treat shrubbery or vegetation where mosquitoes may rest, low marshy places, stagnant pools or ponds, and shore lines. Apply at a rate of 1.5 gallons per acre (4.5 ounces per 1,000 square feet). Using truck-mounted, conventional misting equipment, such as Rotomist models 51C, 91, or 100HT, and traveling at 5 m.p.h. to treat a 300-foot swath, calibrate equipment to deliver 4.5 gallons per minute.
