Onslaught FastCap worked great! I sprayed it around our home in Michigan to keep the crawly critters out. My main concern was with Deer Ticks, Fleas and Spiders for our small dogs. I have not seen any of them. I followed the instructions and the results have been great. 3 weeks now and NO spiders or anything else around the house. I sprayed my grandparents house to and they are enjoying the same great results! They had a problem with Asian Beatles, now the Beatles are gone. If you live in the woods, I highly recommend the Onslaught FastCap.

I looked at what exterminator was using and found the same product online. I bought it mostly for scorpions but it works on everything. I am saving lots of money doing my own pest control.

I use it religiously and every time i find a scorpion it is dying or dead. I live at the base of a mountain and it is rampant with spiders and scorpions especially in the AZ summer ! I really appreciate this product it has no smell like other products. I will continue to use this product...

Moved into a new house and the contractor had put down sod. We ended up infested with all kinds of spiders some not even native to our area. After getting bit by a recluse I decided that drastic measures needed to be taken. Long story short 10 mins after the first treatment I found 3 dead black widows on the sides of the house and 1 inside. Waited 3 weeks and treated again and haven't had any more issues with the spiders.

This is the first product that I have used that was effective in killing both black widows and brown widows which has plagued my yard for years. I needed something that is safe for dogs and this did not cause any problems or leave any odors. Hopefully it will have a sustained effects. Great product. Also, customer service was very knowledgeable and helpful in explaining the comparative advantages/limitations of this product compared with others which was very useful in determining the best product for my situation. I will definitely recommend this to others.

I purchased this becauseI felt like I was starting an immunity to TalstarP after some advice from customer service they recommended Onslaught fast cap. The knock down seems good Flys around the Front or patio etc. Disappear pretty fast but does not have the residual like the TalstarP has. I am willing to try something else extremely happy with DMO solid company.

I just recently applied Onslaught fastcap to our home two days ago. I live in AZ where scorpions are all over the place. I've tried numerous products including Cy-Kick, Demon WP, Suspend SC, Talstar granules and Terro. This is the first time I'm seeing dead or about to die scorpions on my nightly walks with black light after using Onslaught Fastcap. I am will now use Terro spray for spot treatment where I can't reach them. It also kills them just not on contact as they claim. It takes them up to a couple hrs but they do die. Fastcap is now my go to perimeter treatment as it's the only one that has worked for me. I sprayed the product with a ryobi battery powered sprayer and have already seen 4 dead/almost dead scorpions. This has never happened before even with Cy-Kick. I am impressed and relieved even if it does not eradicate them. I am just happy I'm able to control them.

This product is great. Within a day I started seeing a few scorpions dead in plain sight which shows they died before they could get back to hiding. I've good luck with other DOMYOWN products and the service has always been top notch. Thanks

We had a bunch of spiders and webs all over our house and shrubs. I tried conventional bug killer, but it didn't seem to faze them. I found out these are Joro Spiders, an invasive species from Asia. I mixed up the Fast Cap in my sprayer, and killed over 50 of these monsters. It hammered them

Best stuff I have used for scorpions hands down! I have used a lot of different things, equil lambda, talstar, demon…. But this stuff has been amazing!!! I use it as a perimeter treatment around the house and garage for scorpions and spiders. I saw a couple while treating and when I came back around they were dead. Fast knockdown! Now just want to see how long the residual lasts. They say 90 days but the other products I have used here in Florida really give you 30-45 days residual with the rain so we will see. I am very pleased. Where I live there is nothing I can really do about the scorpions because I'm surrounded by woods other than just treat my house and yard to keep them at bay. So far so good!

Very effective year round protection especially in summer against scorpions here in Arizona. We treat both indoor and outdoor once or twice a month especially during monsoon season. Can beat value and effectiveness. Buy it and have peace of mind against these highly venomous creatures. Highly recommend.

Not very impressed with FastCap. I sprayed all around my house, around windows and everywhere I could spray. I sprayed in my house, especially in my bedroom because that's where I've been bitten. 3 days after spraying, I got bit again so I don't know what the problem is

  Expert response:
Onslaught Fastcap is a great option to use for many different pests. Depending on what insect you are treating for, other products may be required and repeat applications as well insects will still be seen in the area as it does not truly repel them. As long as insects contact the treated area they will die but it takes time.

It kills just about every insect. It's instant effects on spiders especially black widows makes me one happy camper.

too early to tell... just prayed... time will tell how effective the insecticide will perform. I do have high hopes. Shipping time was fast. The mixing went well... knowing what is getting sprayed in the real value here. I think some "bug guys" just spray water and charge. I KNOW ITS INSECTICIDE!

I used it as directly in sprayer and I haven't seen a live scorpion since I sprayed. I'm thinking maybe I've won the battle against scorpions.

No scorpions sighted after spraying once a month for 2 months. Temps in the 100 plus range. Slightly stronger odor that Cykick but I only use it outside of the house.

Bought this to see if works on spiders . First time spraying, spiders were coming out of cracks by the dozens ! I knew I had a spider problem but not that bad ! I am very happy it leaves no indication of where I spray ( goes on clear and dries clear ) . I bought this mostly for my surveillance cameras since spiders seek a bit of heat to live and such. Works somewhat okay but I still have to go out daily and remove the webs off of them even though it killed the spiders. Overall a good product and I will keep using it for the time being .

This is my second year spraying a four foot barrier around my fenceline to keep out scorpions. It only took two applications last summer to make sightings exceedingly rare. Quite the change from previous years when I could go out with a UV flashlight and kill 60 a night with a framing hammer.

This insecticide lives up to his claim. i washed my house, followed up with a good spray of Fastcap from a battery operated atv sprayer so i could spray 16ft. vertically. Not one spider, or wasp has returned. I have a corrugated tin ceiling on a out-door kitchen where dozens of "dirt dobbers" were getting in building nests. it's been a few weeks, and not one single wasp. it has a great staying power. Word of caution, due to the overhead spraying,I got drift sprayed on my face and arms on three occasions, and went and hosed off with soap, about 4 hours later,I was burning on both face and hands. so protect yourself with proper PPE.

this is an excellent product. i would like to give it a 5 star rating, but my last purchase was a bit less than 16oz. being so expensive, even a fraction of an ounce matters a great deal.

We have a weekend home in the Texas Hillcountry that is vacant most weeks and Bark Scorpions have made themselves at home during our absence, we tried the common house insect sprays without much success. Onslaught FastCap(OFC) was recommended by our primary home pest control service tech, he said he heard it was suppose to be effective in controlling spiders & scorpions. Ordered the OFC and have been using it for over (5) months following the recommended coverage inside & outside and spraying every (4) weeks. We also keep the grass perimeter around the house closely mowed and make sure there are no rubbish buildups. For the most part, the problem has diminished; we find less and less dead scorpions upon our return, and rarely see live ones. We recommend this product based on the result, we are ordering another bottle.

Company on phone helped me to figure out which product I needed. Best customer service around. The product they suggested worked liked they thought it would. Any questions and they are a phone call away. I give them 5 stars.
