Onslaught Insecticide - Questions & Answers

Onslaught 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.

All of the professional liquid products we sell, including Onslaught, come in a concentrate form.  You need to mix the product with water, usually in a one gallon hand pump sprayer.  Please refer to the product label for more detailed application instructions. Onslaught is mixed at 0.5-1 fl oz per gallon of water per 1,000 sq ft.

According 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.

According to the Actisol manufacturer, you can use Onslaught in the machine. They recommend that you dilute the Onslaught in a seperate container and then add it to the Actisol. Because Onslaught is water based, they recommend that you thoroughly clean the machine and dry it after use.  For further information on the types of insecticides that you can use with the Actisol, you should contact the manufacturer at 877-228-476.

Yes, Onslaught is the same one that is in the Alpine Yellow Jacket Bait Kit. 

No, Onslaught cannot be used on any edible vegetation. We do carry Acephate 75SP, Cyonara Lawn and Garden and Malathion 57%, each of which can be used on different fruits and vegetables. Malathion has the broadest label and is our most popular product for customers that need to treat fruit and vegetable plants. Always read the product label to be sure the plants you need to treat are listed. We also recommend contacting your local cooperative extension office to seek advice on the best products for plants and insects in your region.

Yes, 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.

Yes. 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.

Onslaught is a concentrated liquid insecticide that must be diluted with water. You will use .5-1 ounce of Onslaught per gallon of water depending on what pest you are treating for. We strongly recommend that you read the Onslaught product label to learn the correct ratio for the pest you are trying to get rid of and the area you are treating. For your convenience all product labels are available on individual product pages in the product description box.

You did not indicate what pest you are treating for, but we assume you are treating for bedbugs because of the purchase of Bedlam. Bedbug treatments are mainly applied directly to cracks and crevices where these pests hide. Mopping or wiping down the baseboards should not effect the product that is in cracks and crevices around the baseboards. If we have missed the mark though and you are treating for a different pest then mopping or wiping down the baseboards could remove the residual product and pests crossing over the area would no longer be controlled by the products. It would be our recommendation to avoid wiping or mopping the treated area until the pest insect is gone to avoid disturbing the residual properties of the products.

Generally speaking, Onslaught will kill wolf spiders, but it does not offer a fast knockdown. Onslaught is micro-encapsulated and can take several hours to kill the spiders. We usually recommend Cyper WP because it offers a faster knockdown and the same residual as Onslaught and it can be used for indoor and outdoor spider control. The active ingredient in Cyper WP is cypermethrin, which is known to be one of the top choices for spider control. Spraying Cyper WP will also help to get rid of the insects that spiders feed on and that will help to stop new spiders from moving in. Indoors, spray around all baseboards, door frames, window frames, under appliances, in closets and storage rooms and in areas where utilities (cables, pipes, wires) enter into the structure. Outdoors you should spray around the bottom of the foundation, on the ground adjacent to the foundation, door frames, window frames and places where the utilities enter into the structure and any other place insects can harbor.  We have included Cyper WP in our spider control kit, which also contains glue boards to help monitor the infestation (and help catch the spiders too).

Onslaught is a micro-encapsulated product. Micro-encapsulated products can take a bit longer to kill insects because the capsules need time to dry out and crack open to release the active ingredient. Most insecticides do not kill bedbug eggs which is why it is so important to do follow up treatments at 7-10 day intervals. Concentrated insecticide sprays should only be one part of a bedbug control program. You should also use an aerosol spray with a straw attachment to get into cracks and crevices and an insecticide dust in wall voids and other concealed areas.

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.

Onslaught will kill no-see-ums, however as you hinted any gnat or flying insect will only die if they land on a treated surface and pick up the product on their bodies.  Unfortunately there is no product that will repel gnats or flying insects short of placing a huge net over the house.

Yes. Be sure the children are out of the area while you are doing the actual application and they can return as soon as the area is dry. Do not spray Onslaught on toys or play equipment.

You can expect Onslaught to last for about 4 weeks outdoors for mosquito and gnat control.

Onslaught is safe to use around animals as long as they are out of the area while you are spraying. They can return as soon as the area is dry. Onslaught is odorless, dries clear, leaves no stains, is non-irritating to the skin, and will not break down easily with rainfall.

Yes. Onslaught is labeled for clothes moths and works very well for this pest. It is very important to find the source(s) of the clothes moths and thoroughly clean the item or dispose of it entirely. Failure to do so will lead to re-infestation as the larva will usually remain hidden and continue to develop into adults.

No, the Onslaught product label specifically prohibits the use of this product in a ULV fogger. We do have a large variety of concentrates that can be used in a ULV fogger which can see by clicking here: Fogging concentrates.

Getting rid of the bird nest is always the best course of action. The bird mites that may have made it inside on your children will die very quickly due to lack of a food source and an appropriate environment. For outdoor treatments, you can use Onslaught Insecticide. You can spray your front and back yard but you cannot spray your patio furniture. Patio furniture should be washed with soap and water and allowed to dry in the sun.
