This stuff is AMAZING!! Other sprays that tout to be “on contract” usually fall short. This stuff is AWESOME! And it is only that much better that it's natural. I don't have to worry about our other pets being negatively affected. The only thing that would make it perfect is if it could somehow get rid of the greasy residue it leaves behind. Otherwise, I love this stuff and would highly recommend it!

Product works

I like the natural v. chemical ingredients of this company's products. Easy to spray with effective results. Odor isn't offensive and dissipates quickly. I spray around outside doors, garage, basement every month and, frankly, I haven't seen a bug inside since. I originally bought this produce when heavy rains brought small ants inside..... gone within an hour with one spray. I've been using this product for about 3 months and think I'll stick with it. Price is about half what I've been paying a 'BUG COMPANY' under an annual contract. I have since started using STEM's wasp spray on the outside of my home. I am not paid for this review. Just want to help my fellow Americans so we don't waste money and get quality products. I've been ordering STEM products thru Walmart only but really have no opinion about suppliers.

Buy them all!!

This stuff works GREAT! Smells good, doesn't take a lot, great area coverage with one spray go and zero stress over using it with young kids and animals running around after spraying it. This is a staple! I use every one of their sprays and they're all fantastic!
