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…

The best spray out there. My exterminator recommended this. Wasps die immediately with contact. It sprays far and they don't come back.

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.

It resolved my problem with Germany roaches

My exterminator recommended this to me to get rid of yellowjackets that were nesting in my wall. It works incredibly well and almost instantly. The spray nozzle is a bit annoying sometimes as it will leak a little and the spray will drip onto my hand. That said, I’ll take the dripping for how quickly it kills the wasps and keeps them from returning.

This is not working for me, perhaps an old can. I previously had a bottle of this from my exterminator and it killed on contact. This doesn’t kill with direct contact on wasp.

Multiple applications to a yellowjacket nest (under a slab) and they are still active. Doesn't work any better than other solutions that are half the cost.
