CSI 15 oz Stryker Wasp & Hornet Killer

I use this product professionally and was surprised to find it on Amazon. This is an immediate knock down (kill) of active wasp or hornets at the nest and also kills the larva. I usually leave the nest up with the product on it and it kills the foragers when they return. After 2-3 days you can remove the nest. Good distance stream and I usually get 6-8 treatments per can. Here’s a tip to keep in mind. More is not better! You don’t need to use 1/2 can to successfully treat a nest. Yes, you may use a bit more on a large paper wasp nest, or on a hornet nest, but the product will absorb into the nest and continue to kill. I normally only use a 1-2 second blast which will usually apply enough product to do the job. Happy hunting!

My husband sprayed this entire can down a ground nest of some type of stinging bug. Maybe a yellow jacket or hornet? Either way, after they stung him all over when he mowed over their nest, he sprayed this down their hole and bam. They all died. Worked really well. Will be buying again for our wasp nest that’s next to our outdoor light. Hopefully he doesn’t get stung again…

This is the only thing that has worked for wasps nest so far. We love it. We live in the country (Minnesota) and have a bit of an issue with wasps. This spray has worked and protected us this last year. This is the only thing I will be using. Just make sure you follow all the instructions so you don't get hurt ;)

My go to for the Palmetto bugs (in the roach-looking family but with different behaviors) that love to climb vaulted ceilings far out of reach from anything else. I end up having to get two of these a month because my daughter goes ham and sprays about a half a can just for one bug. The excessive spray isn’t necessary because as soon as this stuff hits any of these roach, looking things, they fall out immediately and then knock out within a minute.Oh, and works for wasps as well, as soon as you spray their nest, you’ll see them dropping out.I gave a four star because no matter what we do and how gentle we are the spray nozzle is doesn’t last as long as the spray does and I end up having to waste a bit of the product. I wish they would fix this because why are we always having an issue with the spray cap?? All they need to do is make it more durable and everyone will be happy.

Worked on a ground wasp nest i had. Took a few days for them to all be gone but did the job

There wasn't much in this can. And I discovered that it has the same ingredients in it as Spectracide Wasp & Hornet Killer. Spectracide is less than $4 with tax. This spray was 17.99 with tax. Over 4 x as much $ for a smaller amount of the same ingredients

We get a lot of black widows in this area, and other products either don’t have the reach or aren’t fast-acting enough for me. This one works quickly and effectively, even on the more elusive spiders. I’ve repurchased it many times—it's a great product. It's a serious poison, so handle with care.

Received the spray today 6/5/25. For starters, it does not spray at a distance more than about 5-6 feet. It did kill the yellow jackets that I managed to hit, and deterred a few that were trying to enter. The kicker is that the active ingredient of the $16 can of Stryker is exactly the same as a $4 can of Raid wasp & hornet spray! And Raid has 0.2% compared to Stryker’s 0.1%.
