## Description

desertcart.com: Harris Spider Killer, Liquid Spray with Odorless and Non-Staining Formula (32oz, 2-Pack) : Patio, Lawn & Garden

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

### ⭐⭐⭐⭐⭐ Harris beats Raid brand.
*by B***R on December 10, 2025*

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

### ⭐⭐⭐⭐⭐ Deltamethrin is simply incredible.
*by A***R on August 26, 2025*

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!
