Sprayed on to Spiders at might. Found them dead in the morning
I walk around the house and spray all the spiders that hang around the roof rafters outside. This spayer stream stays composed so it's easy to hit the spider up another 6 feet away. After they are hit with the spray, they run and hide or drop down to the ground and run. At first, it didn't look like anything was happening but the next morning, they were all dead on the ground. So this spray doesn't kill them immediately but does work well.

Harris beats Raid brand.
Works better than the RAID brand in my experience. Also kills other creepy crawlers, not just spiders.

Deltamethrin is simply incredible.
I have never written a review; but this stuff is incredible! I live in the woods. I have infrared security cameras. Spiders can see the light. They build webs right in front of the cameras. After spraying with the leading brand, in a few days I must remove the webs just to see the yard. You can see 150 feet with these cameras. They are the best! Anyway, I sprayed in my usual way with this stuff. I haven't seen a spider in four months! Believe me when I tell you that my entire house was literally covered by hundreds of spiders inside and out. This is the best spray that I have used in 40 years. Deltamethrin is the effective ingredient. It kills AFTER IT DRIES! UNBELIEVABLY EFFECTIVE!

It does the job eventually
Not an instant killer which I prefer. This is probably safer around pets and humans but that was not a concern in this scenario. The next day I went back to the area to check and all signs of spiders were gone, so it did work.....eventually. Clearing a seldom used storage shed of vermin was the goal. You judge what your purpose is.

We found a few dead spiders the day after we sprayed.
As stated, product was truly odorless and did not leave any stains on our floors.

Works!!
Best spray, I never see any bugs or spiders when I use this product. Does not have an offensive smell and can use indoors and outdoors.

Did not work for me.
I live in California and unfortunately Amazon will not ship the most effective insect to California so I looked for one that they would ship to California and ordered this one. I sprayed it directly onto several spiders I encountered and chased them until they found a hiding place. This product does not work.

Decent bug spray
I bought this product because it had excellent reviews however I sprayed all around my home and I continue to see the spiders alive and well (lol)! The smell is not bad but if you spray too much it can be very overbearing.
