How Onslaught Works

Onslaught is a milky insecticide concentrate made for dilution with water and application with hand or power sprayers. Onslaught contains a versatile active ingredient, Esfenvalerate, that is microencapsulated for superior residual and knockdown. Esfenvalerate is a synthetic pyrethroid, a man-made insecticide created to mimic the chemical properties of naturally occurring pyrethrins.

Onslaught also has the advantage of microencapsulation, meaning the product is a concentrated suspension with millions of tiny capsules containing the active ingredient. When insects come into contact with the spray or residual left from applying Onslaught, they pick up the tiny capsules on the hairs of their legs and bodies, and the esfenvalerate attacks the central nervous system of the insects, causing paralysis and eventual death.

Target Uses

Onslaught Microencapsulated Insecticide is designed to provide long residual activity against pests listed on this label when applied as surface or spot treatments, injected into wall voids, or as a crack and crevice spray in and around residential and commercial structures, as well as on turf and landscaping. Onslaught Microencapsulated Insecticide may be sprayed on any surface that will not be stained by water. Labeled for over 200 insect pests, Onslaught is always a great place to start when looking for a residual insecticide concentrate.

Onslaught is an excellent broad-spectrum insecticide concentrate for use in general pest control applications such as quarterly preventative treatments. Because of the microencapsulation, Onslaught is a great choice for larger, tougher pests such as scorpions, roaches, or spiders. Onslaught also offers great control of flying and stinging insect such as mosquitoes and overwintering pests like boxelder bugs. Microencapsulation also means Onslaught performs well on porous surfaces like concrete without the visible residue of wettable powders.

Onslaught also won’t harm turf and ornamentals and is appropriate for dozens of these pests. Use Onslaught even in livestock facilities such as dairy barns, poultry houses, and horse barns (do not use on animals).

ACTIVE INGREDIENT: Esfenvalerate 6.4%

Application Instructions

Onslaught is designed to provide long residual activity against listed pests when applied as surface or spot treatments, injected into wall voids, or as a crack and crevice spray in and around residential and commercial structures, as well as on turf and landscaping. DO NOT use as a fogger or space spray.

Mixing Instructions:

Onslaught should be mixed with water and applied with hand pressurized or power operated sprayers.

1. Shake container of Onslaught Insecticide before diluting. Clean spray equipment before use.
2. For dilution, add approximately half the required water to spray tank and then add the appropriate amount of insecticide. Agitate and slowly add the remaining water.
3. Agitate spray thoroughly before using and also occasionally during use to ensure dispersion.
4. If spray filter screens are used, they should be 50 mesh or larger.
5. Apply two-second bursts of spray per square foot of area being treated. Avoid excessive application. Dampen surfaces but not to the point of saturation or run-off.

Standard Application Dilution Rates / Mixing Ratios:

• 0.5 fl. oz. (15 mL)/gal. of water – 0.025% a.i. – Light infestations, maintenance, flying insects, ticks, fleas, lice and bed bugs indoors
• 1.0 fl. oz. (30 mL)/gal. of water – 0.05% a.i. – Heavy infestations, initial cleanout, stinging insects
• 0.1 to 1.0 fl. oz. per 1,000 sq. ft. – Ornamental trees and landscapes, lawns and turf – Use sufficient water to cover area
• 1 gallon of finished solution covers approximately 1,000 square feet

Use in the Following Areas:

Indoors and outdoors, in food and non-food areas such as, but not limited to: homes, schools, warehouses, office buildings, apartment buildings, theatres, hotels, industrial buildings, motels, kennels, livestock housing, food processing plants, food service establishments, restaurants, supermarkets and grocery stores, transportation equipment, truck trailers, railroad cars, and food manufacturing and warehousing establishments. Food processing/handling establishments include but are not limited to: restaurants, meat processing plants, grocery stores, bakeries, food manufacturing and processing establishments, and food warehousing establishments. Also for use on backyards, lawns, trees, ornamental landscaping, recreational areas, parks and athletic fields.

Indoors

Crawling Pests: Apply as a coarse, wet spray to surfaces where these pests are normally found. Treat floors, baseboards, around doors and windows, in attics, crawl spaces, eaves, corners, closets, walls, utility pipes, storage areas, and all cracks and crevices. Treat underneath sinks, dishwashers, refrigerators, stoves, the underside of shelves, drawers, cabinets, areas behind pipes, and in all places where these insects shelter. Contact as many insects as possible with direct spray. Repeat applications as needed, but do not exceed more than one application every seven days.

Fleas: Thoroughly apply as a fine particle broadcast spray to infested rugs, carpets, and pet resting areas. Prior to treatment, aquariums and fish bowls should be covered, and pet animals should be removed from the area being treated. Do not permit humans or pets to contact treated surfaces until spray has dried. Old pet bedding should be removed and replaced with clean, fresh bedding after treatment. DO NOT SPRAY PETS WITH THIS PRODUCT. Treat dogs and cats with a product registered for use on animals.

Bed Bugs: Thoroughly clean and sanitize mattresses and box springs. Treat mattresses and box springs with an approved pesticide, such as a pyrethrin aerosol. Apply Onslaught as a spot treatment to potential harborage sites and migration paths, and cracks and crevices, around baseboards, floorboards, head-boards, and walls. Not recommended as the sole treatment for bed bugs.

Outdoors

Other than applications to building foundations, all outdoor applications to impervious surfaces such as sidewalks, driveways, patios, porches and structural surfaces (such as windows, doors, and eaves) are limited to spot and crack-and-crevices applications, only.

Exterior walls, foundations, and structures: To control infestations of listed pests, treat exterior surfaces of buildings, walls, window frames, around garbage cans, eaves, cracks and crevices, porches, decks, gazebos, patios, carports, garages, fence lines, and other areas where pests are active or may be hiding.

To help prevent insect infestation of buildings: Treat a 2 to 6 foot band of soil or other substrate adjacent to buildings. Treat building foundation to a height of 2 to 3 feet. Treat exterior walls, eaves, cracks and crevices, and other areas where listed pests are active, and may find entrance into building.

Apply with sufficient water to adequately cover the area being treated, but do not allow dripping or run-off to occur. Alternate mixing directions are to use 2 to 4 fluid ounces of concentrate per 50 gallons of water.

Insect control for Ornamental Trees & Landscapes: For residential and commercial trees, shrubs, ground covers, and bedding and foliage plants that will not be harvested for food, apply Onslaught in appropriate volumes of water to obtain thorough coverage. Apply as a full-coverage foliar spray, applying to the point of drip but not runoff. Treat active soil pests with an application to surrounding soil. Repeat treatments as necessary to achieve control, using higher application rates as pest pressure and foliage area increases. Repeat applications as necessary, but no more than once every seven days. Certain plants may be sensitive to the final spray solution. A small-scale test is recommended to verify safety to ornamental plants. Spray and observe for one week prior to application of an entire planting.

Insect control for Lawns & Turf-grass: For best results, lawn or turf grass should be mowed 1 to 2 days before spraying. Treat with spraying equipment or a hand sprayer. Use application volumes of up to 10 gallons per 1,000 square feet to get uniform coverage when treating dense grass foliage. For low volume applications using less than 2 gallons of spray solution per 1,000 square feet, immediate irrigation with at least 0.25 inches of water is recommended to improve effectiveness on sub-surface pests. When hand spraying, spray using a slow, even sweeping motion, making sure to cover the entire lawn or turf grass area where pests are observed. Spray under ornamentals and trees. Repeat treatments may be necessary at 7 to 14 day intervals. Use 1 fl. oz. per 1,000 sq. ft. for mole crickets and chinch bugs.
