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. 

Treating carpets for general pests is not needed.  Only when you are dealing with a pest like fleas that infest carpets would you need to do so.  For general pest control, treatments should be directed to cracks and crevices inside as you should also apply a barrier outside around the perimeter.  We have a great video here that shows where to spray for perimeter and interior spraying.  Onslaught is a great option for them and is labeled for over 200 pests.

Onslaught Insecticide can be applied to listed interior crevices once every 90 days. According to the product label, when treating crawling insect pests indoors you are able to repeat application as needed but do not exceed more than 1 application every 7 days.

Onslaught 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.

Yes, you can use Onslaught Insecticide to treat for chinch bugs in your turf. According to the product label, use 1 oz of concentrate per 1,000 square feet. Please take a few moments to review our Chinch Bug Treatment Guide for more tips for controlling this pest.

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 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.

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 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.

Yes, Onslaught Insecticide is labeled for box elder bugs. 

Onslaught SC is a superior product to treat for yellow jackets whether in the yard or under eaves of roofs, patios, porches, etc. It is also labeled for over 200 other insects and great to use as part of a general pest control program inside and outside the home.

For stinging insects such as yellow jackets, wasps, hornets, bees, etc, the best time to treat is at night when they are less active. Mix Onslaught SC at 1oz per gallon of water and spray a 2-3ft radius around the entry point in the yard working your way towards the opening. Next, adjust the nozzle on your sprayer to a pin stream spray. Apply the liquid concentrate directly to the interior of the nest. We alway receommend having a can of Wasp Freeze while treating and spray any emerging yellow jackets directly for a fast kill. With this combination you are killing the adult yellow jackets and leaving behind a residual to kill any hatching yellow jackets. 

Another option is to dust the opening of the holes with an insecticide dust labeled for yellow jackets such as Tempo 1%. This is applied with a bellow hand duster directly into the holes and will be a direct contact as they enter and exit the nest and also treat any newly hatched yellow jackets. 

It usually takes 3-4 days to fully kill a nest but if needed, reapplications can be done as necessary. Please take a moment to review the How to Treat for Yellow Jackets Article located at the bottom of the Yellow Jacket Control Page.

Onslaught 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.
