Manufactured By: MGK

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 of Onslaught Insecticide

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.

If spray filter screens are used, they should be 50 mesh or larger.

4. 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.

Always read the product label completely before use.

Each 16 oz. bottle makes 8-16 gallons of finished solution.

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.

For 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.


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.


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 in ornamental trees and 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 on lawns, turf grass and turf: 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.

    5 of 5 Stars  Highly effective, very economical and long lasting
    By Sean on May 7, 2010
    Verified Purchase

    No odor, and non-staining, leaves no visible film or residue. When mixed and applied at the suggested rates, you get what the manufacturer promises: THREE months of highly effective pest control. It is apparently U.V. resistant, as we are in Arizona, and still get three months out of a single application. For reference, we are using this product for the control of: SCORPIONS, FIRE ANTS, BLISTER BEETLES, and EARWIGS.

    We had a very noticeable knockdown from whatever type of mites we have been fighting using this product. I used it in my car even and have not had anything work this good and the house is so much better. Second application will go down this weekend-I am encouraged! After using many other insecticides this has worked best for us. We just followed direction on the bottle.

    By Carl on December 7, 2010
    Verified Purchase

    Onslaught is exactly as advertised. Works great on bed bugs. Follow all instructions on this product and it will take care of those pests. It beats paying Orkin $1,500 bucks to take care of something you could do yourself for $70. Also be careful of old furniture you bring into your house. No telling what kind of infestation that might be hiding inside it!

    5 of 5 Stars  Onslaught Really Works
    By Paula on May 17, 2010
    Verified Purchase

    Easy application. I did have a bit of a problem getting the liquid into the left side of the container (measuring unit). We love the fact that it is micro-encapsulated. We sprayed around our home, under our home and in the yard.  Absolutely no odor!  It has been two weeks and we just had several inches of rain so I an curious to see if the product will still slow release.  So far, we are extremely satisfied. The main reason for spraying was scorpions. We haven't seen one since spraying.

    We thought it worked very well, we went through a pound of ground turkey a day for 4 days and then it slowed down and so did the wasps, it seemed to take out about 80% of them but we had them really bad this year, we used 3/8 tsp. instead after a couple of days and they still took it. We had to get these guys under controll I am allergic to them and couldn't go out side. We put the meat in cat carrers on the ground and kept our animals safe and it was just a ball of yellow jackets around the cage. We are very happy with the results Thank you.......

    I received this product in good order. I am not sure if it is working or not. I verified it works to control chiggers. I believe I applied it correclty. But there is no way to really know if it worked. I am not sitting in the grass any more. I plan to apply another application in September. We are getting bit by chiggers less. So that's a good sign and hopefully caused by the use of Onslaught.

February 18, 2011 Mat asked:

QWhy is Onslaught so much more than others like Bifen and Conquer?
I did my research on the insecticide portion of my planned flea control program (will be mixing with an IGR). What does the Onslaught offer that products like Bifen, Conquer and Demise do not? The significantly higher price tag must be due to some increased benefits.


Each of the products you mentioned have different active ingredients, or different formulations and different manufacturers. So that we are comparing apples to apples, we will compare Onslaught and Conquer which both have the same active ingredient, Esfenvalerate and both are sold in pint size bottles. Conquer contains 3.48% of the active ingredient and Onslaught contains 6.40% of the active ingredient. You will use 1 ounce of Conquer to make 1 gallon of finished solution for flea control while you will only use .5 of Onslaught to make one finished gallon of solution for flea control. Conquer is labeled for about 50 insects, Onslaught is labeled for about 200. Onslaught also has the benefit of being micro-encapsulated which makes it safer to use indoors and makes it last longer outdoors. 

Bifen is not a good choice for indoor flea control because it cannot be used over carpeting or on furniture It can only be used in cracks and crevices around the perimeter of the room. Demize EC is a great product, which offers a fast  knockdown but it does not offer any residual control and it can only be used indoors.

November 1, 2009 Sterling asked:

QWill Onslaught kill bird mites? Nothing else seems to get rid of them.

AOnslaught will kill bird mites, but the problem with bird mites is finding the breeding source.  Onslaught may provide some relief, however many times mites will breed under carpet or in wall voids, where you cannot spray.  This is why treating for mites is very difficult and usually requires multiple products and lots of vacuuming.

QWill Onslaught continue to kill black widow and brown recluse spiders even after it has dried?

AYes. Onslaught will leave a long lasting residual that will continue to kill spiders for a month or more. Onslaught will also help get rid of the insects that spiders feed upon which helps to prevent new spiders from moving in.

QIs it safe to use a full ounce of Onslaught one week after application?
I have recently sprayed Onslaught in my apartment twice for bird mites at 1/2 ounces per gal. each time with about 8 days in between with Gentrol the first time. Is it safe for me to use a full ounce next after another week?

AAccording to the Onslaught Product Label, you can use Onslaught at the "heavy infestation" rate of 1 ounce per gallon of water every seven days. Gentrol is not labeled for mites and therefore is not recommended for bird mite infestations.

QShould I use Onslaught or Demand for bird mites?
If I use Onslaught and Nylar for bird mites, it should be a good combination? How often should I treat? Can I treat a whole carpeted area and furniture? And of course, I know to do lots of vacuuming!

AYes, lots of vacuuming is required! We recommend Onslaught for bird mite control because it is labeled to spray over carpeted areas. You should not treat more than one time per month. We recommend using Sterifab for upholstered furniture such as couches and chairs. We really cannot recommend the Nylar IGR for bird mites because it is not labeled for this type of insect.

QCan Onslaught and Malathion be tank mixed?
We have a 1/4 acre home garden and 9 citrus trees in Florida. We also have 4 USAR dogs and our sandy soil creates the opportunity for a significant flea and chigger problem.

Brought into house on clothing from chicken coop

A Yes the Onslaught is labeled to control all different types of mites. Spray down all the cracks and crevices of the home very well, baseboards, window and door frames, etc. You may also want to use Evergreen Pyrethrum Dust in areas you are not wanting to spray as this is a great product for chicken mites as well. Make sure to vacuum well and wash and dry any clothes or linens in hot water and high heat.

I want to use onslaught indoors against bird mites. Under the usage instructions it sounds like it can be sprayed on bare floors. I would want to spray it all over my bare floors and walls and carpet but I go barefooted a lot, so would this be a problem?

A Yes, you can safely and effectively spray Onslaught Insecticide indoors as a floor broadcast for bird mites. Be sure to allow the floors to fully dry. Once the treated area is fully dry you may re-enter the treated area with bare feet safely.

QCan I use Onslaught in my solo mister/what benefit over talstar if any?



Onslaught can be used in the Solo mister and will work just as well as Talstar P. Onslaught is microencapsulated so the residual does last longer than Talstar, which means less applications, but the price per ounce is higher than Talstar.Although, both insectcides will deliver exceptional results.

March 20, 2014 Ruthella from Carrollton Ga asked:

QI ordered Onslaught from you before and I am using it outside my home and my rental house to keep bugs at bay.
Is the Onslaught the BEST product I can be using to do this job OR is there something BETTER I can use? I want to use the BEST product to KEEP BUGS OUT OF THE HOMES I own. If you think there is a better product you can sell me for this, can you please let me know what to buy? Thanks so much.

A Onslaught would be a great choice because it is labeled for over 200 insects and has a 30 day residual outdoors. It also can be applied to indoor crack and crevices once every 90 days. You should treat around all the cracks and crevices (inside and out), window and door frames, a few feet up the siding of the homes and the lawns. Without knowing exactly what insects you are treating for it is hard to give you the best treatment advice but this is a professional strength product that will cover numerous flying, crawling, biting and stinging insects. Just make sure you are mixing and spraying as directed on the product label.

QI am living in the state of Florida with 4 bedrooms, plus my two automobiles are full of biting mites.

A You can use Onslaught indoors and outdoors of your home. Onslaught Liquid Insecticide is micro-encapsulated, meaning that after the product is sprayed, the active ingredient is released slowly over time, producing long-lasting residual control of insect pests.

To treat mites in your car you could use a product like Cykick Aerosol along cracks and crevices. Then you can use a product like Sterifab on top of seat cushions. This product labeled to be used in areas where you may come in contact with.

QHow long does Onslaught remain active after its been sprayed on baseboards and around entry ways etc?

A Onslaught Insecticide has a residual time of 2-3 months. When treating for roaches we recommend to reapply Onslaught once every two weeks. You also want to be using Roach bait like Maxforce Magnum roach bait gel.  Using a roach bait will ensure that the active ingredient will be taken back to the nest.
