Bests & Worsts Reviews from Amazon

I thought I had killed a huge brown widow spider with this stuff, but a few days later, it was gone from where I’d left it...and back to making huge webs on my patio! I learned from the exterminator we later hired that because of environmental laws (particularly in CA), this stuff is water-based and doesn’t actually kill most spiders...so make sure you have some good closed-toe shoes to stomp on them once you’ve disabled them! TL;DR: only disables spiders, so you’ll still have to set your house on fire to kill them.
