No harsh chemical spray for ants, roaches and flie

[This review was collected as part of a promotion.] This plant based product had a pleasant smell. It doesn't contain any harsh chemicals so you don't have to worry about little ones or pets. The spray bottle was easy to work and it didn't drip after spraying the area. It worked well when sprayed directly on ants. It might be a little more pricey than other ant sprays but knowing that it doesn't have any harsh chemicals was an easy sell for me.

Safe and effective

[This review was collected as part of a promotion.] Our house is in a very wooded neighborhood and with that comes bugs. Lots of them! It is their home too after all. But because we have pets and kids, I've always hesitated to purchase mainstream pest control products. I was very happy to see this natural line of pest control products that are available everywhere! And they aren't just accessible, they're effective!! We were shocked how quickly this spray takes effect on pests around the house. The only knock I have against it is that you'll want to make sure to wipe up any spray on the floor. It's a little slick. It smells like lemongrass which is miles better than anything else we've tried. I will definitely be buying this brand for the foreseeable future!

Definitely kills flies!

[This review was collected as part of a promotion.] This actually works to kill flies. When they land and you spray them, they can barely fly after and later die. The scent isn't harsh, and I sprayed it around my houseplants, so we'll see if the ones near it are affected. I will say it's very greasy so spraying bugs anywhere that wouldn't be easily cleaned after.

Strong effective product.

[This review was collected as part of a promotion.] Effective product, it was easy to use and came in a quality bottle. I'm glad it warned me to not use it near pets and kids though because I would say you shouldn't uses those spaces for several hours after as it has a very strong chemical scent.

No More Ants

[This review was collected as part of a promotion.] We always have an ant issue at the beginning of summer, so I was excited to give the Stem bug spray a try. I am always nervous to use these types of products around my house because of our pets, but this one is made from botanical extracts. It's not a spray to 'spray and forget' but rather, one you spray directly at the little buggers. It killed them almost instantly. I was very impressed with the effectiveness and will continue to use this product whenever the ants reappear.

Works!

[This review was collected as part of a promotion.] STEM, ant, roach, and fly spray has exceeded my expectations. There were little sugar ants in my mother's kitchen, and I have seen a major decrease. The spray has a pleasant smell, that may be strong for others, but I didn't mind it. The consistency of the spray is very liquidy with it almost being a little oily. When spraying, I used a paper towel to help spread it along the edge of where I sprayed. I think it is overall effective and I would continue using it.

Effective, but strong smell

[This review was collected as part of a promotion.] The product seems very effective at repelling ants and other bugs from areas where you spray it. I like that there's a clear on and off toggle for the spray. Two things to note - there is a slight smell, and if using this spray on carpet it may leave a stain over time (as seen in the picture).

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 favorite product. I'll stick to the flyswatter inside and maybe use this outdoors but even that makes me nervous because I'm not sure if it'll stain certain surfaces.

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.

Problem solved

[This review was collected as part of a promotion.] Stem for ants, roaches and flies works great. We were having an issue with ants around the dog food and it has done such a great job of keeping them away. It was easy to find at my local stores and a great value. It works great for both inside and outside of the house. It does leave a mark when sprayed on certain surfaces (looks like oil sprayed) but works great and the mark eventually goes away.
