Works

I've had Terminix and Orkin at one point or another spraying my house. We started buying this 2 years ago. Cancelled our bug service. This definitely kills them. I find dead bugs everywhere after my husband sprays. I mean we still see spiders and scorpions we live in the country. But it's getting better every year we see less. So it does its job.

Effective

Love the ease of use of this as it comes with a power sprayer that does not fatigue your hand. I use it every 3 - 4 months around the perimeter of my home's foundation and it works great to deter most bugs. This year people have been swarmed with earrings in my area and we have only had a few get in. There are dead earrings outside daily, which is great because the only good earwig it is a dead one. It doesn't seem to work as good on spiders but not bad enough to lose a star.

I get this to use with the original jug that came with the electric sprayer. It says it works for 12 months. I use it every month over 2,000 ft . It's cheap enough to use every month just for peace of mind and it definitely is hundreds of dollars cheaper than Terminix every year.
