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.

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.

Works great!

I have been using this in and around my house and I see a lot of various types of bugs dead, centipedes would be the worst and I've seen dead ones, bigger ones take a direct spray and it's very effective. I also bought a Craftsman battery powered sprayer that works way better than the Ortho one. Been using it for about 2 years and still works perfect. I alternate bug spray with plant killer.
