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.

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.

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.

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.

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 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 not labeled for Cheyletiella mites and this type of mite does not live off of the host animal and do not infest the environment.  This mite is contagious by direct contact with other infected animals only. If a dog is constantly infested it could mean that an egg or mite was missed/still exists on the animal or they are being introduced from contact with infested animals.  We recommend that animals are seen by a veterinarian and treated according to the veterinarian's instructions.

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.

Onslaught is a micro-encapsulated product which means it is a time released formula and can take a little longer to kill insects than other products. Ants can take several hours to a day or so before they die after coming into contact with treated areas. Onslaught will not stop ants from coming into an area but it will kill the ants that do. Onslaught does not transfer back to the colony. We always recommend that you use an ant bait gel or granule in addition to the insecticide spray since ant colonies can be very large and they can keep sending out worker ants. The bait will be carried back to the colony and fed to the other ants and this will help speed up the ant elimination. We also recommend spraying outdoors around the perimeter of your home to eliminate ants before they move indoors.

Onslaught can last up to 60 to 90 days on outside surfaces but it can be applied as often as every 7 days if needed.  Generally most people apply once a month and it is still effective in rainy areas.

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. 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.

Yes, Onslaught Insecticide is labeled to be used on carpeting.  Be sure to follow the instructions on the product label.

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