Great Pet Safe Product

[This review was collected as part of a promotion.] I really love that this is made with natural ingredients and safe to be used around pets. We have several inside animals and their safety is a priority. We've used this in our RV to keep out the ants and flies. It has a pleasant smell and sprays nicely for an even coverage.

STEM NO CHEMICAL SMELL

[This review was collected as part of a promotion.] Im not going to lie I didnt have high hopes for this spray to work on ants because its marketed as not being harmful. And that tells me if it doesn't have the chemical smell n probably wont work..but surprisingly it does..I didnt have to open the windows to air out the toxins and all that..now ungotta keep up but it does work.

On my third bottle!

[This review was collected as part of a promotion.] I LOVE this spray — this is my third bottle! I’m definitely a person who stays as far away from bugs as possible, so I really appreciate that the concentration and long reach of this spray lets me stay a good distance away as I spray unwanted critters. I feel comfortable spraying this in a house full of people and pets as it’s safe for both, and love that it’s a natural formula to make me feel extra confident in this.

Strong scent

[This review was collected as part of a promotion.] I like that this is a natural product and it does seem to work. It only works on contact with bugs. Besides that, I think the product smells very very strong. It smells like essential oils but it is very strong. It is super oily and I had to wipe it off after I sprayed it. It is hard to hit a bug with the spray unless it’s ants or something slow. I didn’t trust spraying it many places since it is oily I assume it will stain. This is not my favo...

Great product to help prevent critters

[This review was collected as part of a promotion.] Very easy to use. Bottle has worked very well for the exterior of my home. Not letting flies roaches or ants. Get in safe for animals and people has a pepper mini smell but that is for helping keep the critters away. Overall a great product.

Great product!

[This review was collected as part of a promotion.] I’m really impressed! I love that it’s a clean, plant-based option—especially important with a toddler in the house. It gives me peace of mind knowing I can keep pests away without worrying about harsh chemicals.

Eh

[This review was collected as part of a promotion.] I didn’t find this item very effective as I still got many bugs indoors. Many many flies around my house so the spray may not be the issue of the product but unsure.

It’s good

[This review was collected as part of a promotion.] It’s a soft approach to traditional insect spray. It does have a smell that i am not crazy about, but i like the fact that is safer for plants and around the house overall. I like the bottle spray, better than the other spray. The price is reasonable for the amount.

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.

Scadimg hot water works faster

[This review was collected as part of a promotion.] I received this product for free in return for my honest review of the product. I really didn't care for this product at all nor will I be purchasing it again. The scent was pungent and it hung around for hours afterwards. I had tried to use this product to kill ants that were around the outside of my home and it didn't kill them unless I really drowned them with it. I could have killed them faster with scalding hot water.

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 thi...
