Stem is a one shot killer. It's severely effective, they don't like the smell, they fall and die less than 30 seconds. When summer comes again, I'm getting a case!! I'm painting my kitchen and Im ordering after Xmas. The smell is different but not overpowering. I spray before work and come back , all gone. YEAHHHHHHHH!!! TRACY🔥

I recently tried this bug spray, and I am thrilled with the results! It works instantly to eliminate pesky bugs, which has been a game changer for my home. I love how quickly I can see the effects—it really gives me peace of mind. What's even better is that the product is both effective and safe around my kids. I can use it without worrying about harmful chemicals or potential hazards, which is a huge relief. It's great to have a solution that protects my family while keeping our home bug-free. I highly recommend this product to anyone looking for a reliable and safe way to tackle bug problems!

STEM the bug killer

STEM works very well. It kills all types of bugs. I had a problem with carpet beetles and STEM killed them instantly. The only problem is that this product has a faint unpleasant order. However my husband disagrees and says he can not smell it. Either way a little ventilation is well worth this small inconvenience for this very effective bug killer.
