Bed Bug Supply Review - see what our experts have to say about this product

Onslaught uses a unique micro-encapsulated chemistry to provide a very long-lasting residual strength. This slow-release technology allows Onslaught to kill bed bugs, fleas, spiders, and a wide range of other insects for up to 5 months.

Onslaught boasts possibly the longest list of insects controlled of any chemical we carry - it can be used to control over 175 different species of crawling, flying, and plant pests. Using Onslaught is easy: just mix 1 fluid ounce of the product with a gallon of water in a hand pressurized or power-operated sprayer. Shake the tank to agitate it and you’re ready to rock.

To control bed bugs, we recommend using Onslaught as a spot treatment on places where bed bugs are likely to hide and travel. This includes headboards, floorboards, and where the walls meet the baseboard. Focus your spray on cracks and crevices to ensure that they get filled with the mixture.

Product Information

Onslaught is a microencapsulated residual insecticide. What that means is that the chemicals are encapsulated, and slowly release over time. That slow release allows for an incredibly effective residual protection. Onslaught's flexible label allows for use against a broad range of tough pests, like bed bugs, roaches, scorpions, spiters, and more.

For use against bed bugs, start by thoroughly cleaning and sanitizing the mattress and box spring, and treating them first with a contact killer. Then, apply Onslaught as a spot treatment to the seams and folds of the mattress, the corners and other tight spaces of the box spring and bed frame, and other cracks and crevices around the room.

Questions and Answers

Q: How do I mix this ? I do not understand it to well. I think is 1oz to 1 gallon of water. Please Help this for water bugs. Thank you
Asked by: Nellie - 5/16/2014
You'll need a gallon-sized hand-pump sprayer to use this product. Fill the spray tank halfway with water. Add the Onslaught (half an ounce for light infestations, or one ounce for heavy infestations), then fill the tank the rest of the way. Then simply shake the tank up to mix it, and you're ready to start spraying.
Q: hey, I wanted to ask that, if this is also effective to use in crops...... crops like cotton, maize etc ...... or it is just for home use. if done in fields... which crops would that be?
Asked by: ZARAR - 3/31/2020
Onslaught is not labeled for use on crops and we do not recommend using it for such an application.

Have used this product for over a year. Spray my house every three months like the pest contol companies. I have to say this product is great. I have elimated my black widow, brown widow, ear wig and ant issues. And if spray I large section near the door way it prevents flies from landing near the entrance of the door way during the summer months and flying in when I open my door. I let my dad use some and it elimated his flea problem in his yard. I highly recommend this product. A lot cheaper than hiring a pest control company.
