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.

Bitting mites
By Aurore on August 4, 2010 Verified Purchase
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.

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.

Great product
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!

Been great so far
By A. on April 11, 2013 Verified Purchase
We had an infestation of Box Elder bugs and the normal herbicides I could buy locally did nothing. I used onslaught last week at the recommended levels spraying around the perimeter of the house both inside and out and haven't seen a single bug since. Not a single one! Will have to wait and see how long it holds up but I won't complain a bit if I need to reapply in a month. Just as an FYI: I live in the country and am surrounded by a forest preserve and bugs have always been an issue. I think I may have found the answer I've been looking for!

Onslaught Insecticide
By Chuck on August 6, 2012I have used this stuff on my house twice this summer at 1oz per gallon mixture in a spraying device I bought from this company. All I can say is it has kept the wasp and carpenter bees away from the house. I was paying some company $300 to do the house and this insecticide work just as good.

Midges
By Melva on June 16, 2012Did NOTHING for midge control. Mixed 1st time @ .5% with no success. Ordered more onslaught ($$$), mixed @ 1% hoping for a big reduction at the very least. Two days later, the regular 'dusk swarm' was worse than EVER. Could not breathe without nose and mouth invasion and the high-pitched noise from their tiny wings in flight of the massive swarm was very loud. Bottom line...did not/does not work on midges as listed. They are still 'daytime nesting' in shrubs, grasses, and tree's bark that were very carefully sprayed/treated.

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.

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.
A 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.

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.

August 26, 2010 Debi asked:
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.

July 14, 2010 Aurore asked:
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.

Pat from Covington, La 70433 asked:
QHow do we get rid of chiggers at our cabin in mid LA?
We are in our 70's and can't go outside in the Spring , Summer or Fall with out getting multiple bites even when we are riding a mower. It's an awful infestation.
AOnslaught is a great product for chigger control. Treatments for chiggers should begin in April/May and could need to continue through the summer as new chiggers move into the area. Treating the entire lawn is of little benefit because chiggers avoid direct sunlight and normally will not infest areas that are mowed or otherwise well maintained. Focus treatment on the unkempt areas of the lawn and lawn edge. You can also use Onslaught to do a barrier treatment around the outside of your home and in your crawl space to stop pests from moving indoors.

Jason from Ohio asked:
QI have 3 small children is onslaught safe for children after the application dries?
I want to make sure I understand what I need to do when re-entering home.
AOnslaught is safe to use in a home where children reside as long as the product label is followed and the children are out of the area while the product is applied and until it has dried. There are no extra precautions that need to be taken before re-entry.

Michelle from Perry, Oklahoma asked:
QIs Onslaught safe around pets?
I have two miniature dachshunds that stay indoors most of the time and two rottweilers that are on the outside. We want to treat our home for scorpions, wolf spiders, flees and other insects but want to make sure it is safe around our pets.
AOnslaught is pet safe as long as you follow the product label. Be sure pets are out of the area while you are doing the application and they can return to the area as soon as it is dry.

Jacqueline from Gainesville, Georgia asked:
QIs Onslaught Dangerous when rewet following application drying. Kennel Floor wetting
or if it Rains does it kill the effectivness. How long between spraying for Major Flea Mite issues and Mix ing Measurment.
AOnslaught will not reconstitute if it gets wet after it has dried so it will not be dangerous if it gets wet again. Onslaught can last for up to 30 days indoors but can be reapplied up to every 7 days if needed according to the Onslaught product label.
August 3, 2012
Elaine from Dallas, Ga asked:
Qhow long do I have to wait to wash my kitchen floor after Onslaught has been applied for roach remediation?
AYou should be able to wash your floor right away as Onslaught is only supposed to be sprayed into cracks and crevices around the door frames, window frames, places where utilities (cables, pipes and wires) enter into the structure and around the baseboards for roach control.
June 10, 2012
Evelyn from Ealing, West London, England asked:
Qhow do I apply Onslaught insecticide and how much should I use?
AThe application rate will vary depending on what you are treating for and where the product will be applied. In general you will dilute 0.5 fl-1.0 fl oz in one gallon of water and apply the dilution using a hand pump sprayer. Please read the Onslaught product label for complete usage instructions.

QDoes Onslaught kill Springtails?
I have had Springtails in my bathroom and outside around water fountains. Also I have a small open Atrium that they seem to be coming from into the bathroom. I was wondering will Onslaught kill them. I have had the area sprayed before and seems they never really go away.
AOnslaught is labeled for springtails and should help you to control them when used as directed on the product label. You will not get complete springtail control until you locate the source of the springtails and correct the conditions that are allowing them to thrive. Please take a few minutes to read our article"How to Get Rid of Springtails" to learn more about springtail elimination.

A from West Palm Beach asked:
QIs Onslaught good for noseeums?
AOnslaught is labeled for a wide variety of small flying insects including gnats, midges and other small biting flies and should help reduce the amount of noseeums on your property. Be sure to spray the areas where you have noticed the noseeums landing or resting as Onslaught will only eliminate those insects that land on treated areas.

Bart from Austin, Tx asked:
QWhat should we do if Onslaught was sprayed on our herb garden?
My small herb garden was sprayed by our pest control guy with Onslaught. How long, do we have to wait before using the herbs? (Infinity?) Do they need to be washed, or should I just plow the whole lot under and start over?
AWe recommend you contact the manufacturer directly for information as there could be several variables they may need to know before they can tell us for sure what needs to be done. You can reach MGK by calling 800-645-6466.
