Onslaught Insecticide - Questions & Answers

If she is throwing up, we recommend that you contact your vet. You can provide the MSDS for Onslaught to let them know more about the product that was applied in the home.

Onslaught has a 30 day residual outdoors. It can also be sprayed indoors every 90 days in the cracks and crevices.

Without knowing exactly what you are treating for, it is hard for us to make a product recommendation that will fit your specific needs. We do carry a product called Onslaught and it is widely used for general pest control and is labeled for over 200 different insects. You will mix and apply according to the product label instructions when the children and dogs are not in the area. Once it is dried completely, they can re-enter the treated areas. Please read the product label for mixing and application instructions.

You want to make sure when you are using products for fleas that you are spraying every 2 weeks and not any more often than that so that you aren't creating any resistance issues. Make sure you are keeping your grass short as this makes it harder for the fleas to thrive in your yard. If you believe the fleas are coming from the animals, you may want to try an animal repellent or deterrent to try and drive them away from your yard. One of the best recommendations for flea control we have would be the combination of Onslaught and Nyguard IGR. Onslaught is micro-encapsulated and sits on the surfaces you spray better and holds up to the outdoor elements longer before breaking down. The NyGuard IGR is formulated for fleas and many other insects and can hold up to sunlight for roughly 5 months. If you have tried several products and they are not working, you may want to get a sample of the insect to take to your local Cooperative Extension to get it properly identified by the Entomologist on staff. Treating for the wrong insect can often make your problems worse, so getting an identification from a trained professional is always recommended.

Onslaught is labeled to control mosquitoes. Be sure to refer to the product label for the best usage rate for the area where you will be applying Onslaught.

Onslaught 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.

There is not a definite time to say Yellow Jackets will be eradicated. We can say you should see a decrease in activity within 7 days.

Yes, Onslaught is a great product for spiders in general, including brown recluse spiders.  It is also labeled for almost a hundred other insects.  When treating for spiders inside, it is also advisable to use insect glue boards around the home in corners and behind furniture, etc....to help monitor the situation.  Glue boards are excellent for catching insects and keeping tabs on an insect situation.  

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.

Onslaught can only be tank mixed with a synergist or an IGR but not with other insecticides. Also, Onslaught is not labeled for use on or around any edible vegetation whether it be a garden or fruit tree.

You will mix 1.5 oz of Onslaught and 4ml of NyGuard to 1.5 gallons of water to treat 1500 sq ft. You will apply once every two weeks (minimum of two treatments). Please take a few moments to review our Flea Treatment Article for additional helpful information.

The Onslaught Insecticide should be stored at moderate temperatures and shouldn't freeze. However, if freezing should occur then dethaw at room temperature. Do not heat to speed up the dethaw process. It is hard to say whether the Onslaught Insecticide needs to be replaced besides decreased efficiency.

Onslaught 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.

Onslaught is a great product for control of yellow jackets. You could apply it via a hose-end sprayer. It should be diluted 1oz per gallon of water. Another great way to treat for yellow jackets is by applying an insecticidal dust such as Tempo to their nest. Night time is the best time to treat because that is when yellow jackets are less active.

Onslaught Insecticide cannot be used on any pasture area or anywhere that animals graze, even after dry.

Onslaught is safe to use in a home where children reside as long as you apply it according to the label and the children are out of the area while the product is applied, until it has dried. There are no extra precautions that need to be taken before re-entry.

Yes, Onslaught Insecticide is labeled for box elder bugs. 

Biting midges do generally not enter structures, but midges are small enough to get through 16 mesh screens. Getting mesh screens with a higher number can keep these and other very tiny insects out of your home. Since non-biting midges are attracted to lights, draw your shades at night and wait as long as possible to turn on exterior lights to keep them away from your home. Onslaught is a liquid insecticide labeled for midges and can be used inside and outside the home. Spraying Onslaught on window screens, doors, bushes, and plants around your home can act as midge repellant to keep midges away. Inside the home we recommend thoroughly vacumming the entire home. Dispose of the contents immediately in trash bag and take outside. Apply 1oz of Onslaught per gallon of water 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. Continue to vacuum daily in between treatments.

Onslaught Fastcap would offer a faster kill to those sprayed directly during application but once dry would effect bed bugs at the same rate as the regular Onslaught.  This is due to the added actives in the Fastcap.

Onslaught will only kill the leaf cutter ants that come incontact with the treated areas. Leaf cutter ants can have very large colonies, making it difficult to eliminate. We recommend using Maxforce Complete Granular Bait. Maxforce Complete contains hydramethylnon which is effective, though they will usually eliminate only about 30% of a large colony in one treatment and will need to be reapplied several times.  Deltagard granules   would also be a recommended product. The product label recommends treating the mound directly and lightly watering the granules in.
