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.

Bug Free

I pour this 1 Gal. refill onto my own 1 Gal. pump sprayer. I spray the outside perimeter of my home and it keeps the pests out. Florida is home to over 30 species of cockroaches. It does a good job of keeping the cockroaches out. I spray about every 6 months or so.

Great Value, Effective Results, No Problems!

We use this product weekly, both in our home, our screens, on our porches, around all exterior doors and thresholds throughout spring, summer and fall. In winter, we spray monthly. We have had no problems in using it and very successful results. The refill jug is a true value. Home Defense has low odor, has never discolored any fabrics or carpets, is safe around pets after it dries. Honestly, we have had better results using this product than professional treatments and won't go back!
