Kills flies instantly... & smells great!

I normally don't like using any type of bug killers in the house, unless absolutely necessary, since I have pets. With the STEM Bug Killer Spray, I can use it indoors without worrying about safety concerns. We've been getting flies coming into the house this summer & this spray has been the best solution. It kills the bugs instantly yet is safe to use throughout the home. It's made with plant-derived ingredients & extracts, including geraniol & lemongrass, so it smells great as well. Highly recommend if you are looking for a pet & child safe bug spray!

Would purchase again

I received product reimbursement in exchange for my honest review. I had not heard of this brand prior to testing it out, but so far I am pleased with the product. I like that it is safe to use around pets and children as we are a household with both. I enjoyed the scent of it as it did not have the typical strong bug spray smell to it. It seems to work pretty well on the ants so far, but I cannot say how it will work in the long term. I would definitely purchase again.

Good bug spray

I received product reimbursement in exchange for my honest review. I thought this was a pretty good bug spray. I really like that it is safe to use around pets and it seemed to get rid of the few pesky flies that I had in my kitchen. The only thing I didn't completely like was the smell. It seemed to initially have a lemongrass scent but when sprayed it smelled a bit like chemicals. Luckily it didn't linger and seemed to fade away after a bit.

Safe without harsh chemicals.

I received product reimbursement in exchange for my honest review. I was interested in trying Stem to help with an ant problem I have outside the house. I definitely don't want the ants to march themselves inside. I sprayed this a few times where I had been seeing ants and so far it seems to be a deterrent. I'll see how it goes over the next few days, I may need to spray a few more times. I've been resisting using a harsh chemical because of pets and the likelihood that it would kill more than the bugs I don't like but the pollinators or butterflies. Hopefully the plant botanicals won't harm the "good" bugs.

Works for Roaches
5 out of 5 stars review

Would Buy Again

Our apartment complex has continual issues with roaches. I sprayed this on the baseboards and borders of all our cupboards including in kitchen and bathroom. I have a cat and kids. The smell is strong like tea tree but, I liked that it left behind the oils where I sprayed because not only did it kill roaches on direct spray, it killed them whenever they contacted the oil, and I haven't seen any in weeks. The only thing is the oils linger on whatever it's sprayed on so hardwood or laminate floors become slick. I'm going to buy it again and continue to use as described.

Safe and Effective

I received product reimbursement in exchange for my honest review. First of all, I really liked this product because it is safe for pets and kids since I have both. Secondly, it was effective at keeping ants out of my kitchen, which is where we usually get them. The smell was a little different, in my opinion, but not too strong. I would recommend.

Great for our RV inside and out

I received product reimbursement in exchange for my honest review. Ants tend to be our biggest concern every time we go to a new campsite with our RV. I was pleasantly surprised how well this worked inside the living area as well as storage compartments underneath. It left a pleasant lemongrass scent as with no worry for anyones safety and In a bottle that is perfect to keep in the RV.
