Perfect for ants!

[This review was collected as part of a promotion.] This STEM spray has been perfect for getting rid of ants in my house. I love that you can use it indoor and outdoor. Since it's plant based, I feel more comfortable with spraying it in the house around my dogs opposed to other brands. It's super effective, works so quickly, and easy to clean. The scent is also not overwhelming! The bottle is easy to use and definitely worth the money.

It Works!!!!

[This review was collected as part of a promotion.] This stuff works!! I had a wasp nest on my porch I decided to try this and they started dropping!! The smell I think reminds me of a mosquito repellent. It may be a bit oily. The price is great for the job it does and the packaging is nice too. I would definitely buy again and I would highly recommend especially since it's safe around kids and pets.

STEM Bug spray works effectively !

[This review was collected as part of a promotion.] I tried the STEM Indoor and Outdoor Bug Spray and was impressed with how well it worked. It killed ants and flies on contact, and I felt comfortable using it since it's plant-based and safe around kids and pets. I also really liked the light lemongrass scent it's much better than the strong chemical smell of other sprays. The only small downside is that I needed to reapply it a couple of times, and it can leave a slight residue. Overall, I think it's a great eco-friendly option that I'll keep using.

The best!

[This review was collected as part of a promotion.] This is a fantastic bug spray! It's extremely effective; ants and roaches worst enemy, flies too. It has a strong herbal scent, which is not unpleasant. You only need to use a little at a time so the bottle definitely lasts. It's also super easy to use, just spray and you're done. I also love that it's safe to use around people and pets!

Safe for Pets

[This review was collected as part of a promotion.] I don't use insect sprays often because I have a dog and worry about how it could affect him in the long run. This one specifically says that it's safe for pets, which gave me peace of mind. Lately I've had issues with ants! They're all over my potted plants. Tried this out, and it was very effective around my plants. I didn't spray directly though because I wasn't sure if it was plant safe as well. Pretty scent less as well.

Kills bugs, smells good, no poison!

[This review was collected as part of a promotion.] The STEM ant, roach, fly spray works well without using poisons. The bugs die within about 10 to 15 seconds after being sprayed. The residue appears the keep them away, as well. I used it on sugar ants getting in the house-or killed them and kept them away from the area for several days. It does have a strong smell, but it's a lemon grass scent.

Works well, smells good

[This review was collected as part of a promotion.] Nobody wants to deal with pesky ants. Our pest control missed any areas under the pool cover but once off, we had several areas to deal with. This spray handled with ease and smelled a lot better than competitors.

Effective!

[This review was collected as part of a promotion.] This was very effective, we actually sprayed the screen door going into our garage and it worked quite well. I would say our only complaint is that it is rather oily. We sprayed a little haphazardly and it made our kitchen floor slippery. So we will be more careful when using next time. It has almost light citrus scent so it was rather pleasant for a bug spray! I would recommend this product.

Safer option

[This review was collected as part of a promotion.] Seems to work well. I like the fact that it's a safer choice than other ant and roach sprays out there. Safety is a big factor for my household. The only issue really can be the residue it leaves.
