Ineffective

I received product reimbursement in exchange for my honest review. I sprayed the product directly on a handful of ants. They appeared a little irritated, but walked away after a few minutes. The bottle says virtually nothing except "kills ants, roaches, flies", and it doesn't appear to do that. The packaging is very short on information and the product doesn't appear to do anything.

This works within 1-2 seconds

I received product reimbursement in exchange for my honest review. This was a unique product. I really liked it. We have little, red, fire ants all over our driveway. My husband has sprayed the driveway with other pest control formula and didn't work. As soon as I sprayed this, they died within 1-2 seconds. The scent is quite strong and something I would avoid inhaling while spraying this. But I can tell it has some natural ingredients in it also. I think my only complaint is the price. It is quite expensive for the size you get, but somethings are worth paying extra for if they get the job done. I would recommend this product.

I am satisfied so far.

I received product reimbursement in exchange for my honest review. I live in a very grassy area with all sorts of insects. My favorite part of this product is that it is safe for kids, as I have a 2 year old. So far the product works good. I haven't seen any bugs since I've sprayed by the front and back doors. I look forward to purchasing their insecticide for spiders, although I haven't seen spiders since spraying this product. I look forward to seeing how things are down the road.

Works great!

I received product reimbursement in exchange for my honest review. I have, or rather had, ants crawling around my windowsills and with the weather getting warmer I didn't want a trail of them coming into my house, so I sprayed a little STEM along the window line. Ants were dead on contact! This was a couple of days ago and I still don't see a single ant in the area so it must also work as a deterrent. Very pleased with this product and I much prefer the pump spray bottle over an aerosol because I can better control where it goes.

Effective with reservation.

I received product reimbursement in exchange for my honest review. This review is for STEM Ants Roaches Flies. My intent was to use this on flies, which are particularly overwhelming this years. I will say that it successfully killed any flies on which it was sprayed, but that is my problem. I would prefer to not wait for the flies to have landed bc then it's a race to spray before it flies away again. Also, it leaves an oily residue which is not easy to clean up. It may be better suited for ants which do not move so fast.

Solid product, oil-based and strong scent

I received product reimbursement in exchange for my honest review. this bug killer is a solid product that seems to be safe for pets and kids, safe to the touch and includes a somewhat pleasant fragrance, although it is strong. it seems to be oil-based, so you can't really wash it off your hands easily with water and soap, and it won't necessarily evaporate and disappear like other bug sprays. overall, it seems to do the job And I would recommend it to other people.

Mediocre product; strong smell

[This review was collected as part of a promotion.] I had a massive ant outbreak in my car thanks to some crackers that got trapped in my daughter's car seat. I used this product to spray the baseboards of the car since it said it was safe to use around kids and pets. It did not completely eliminate the problem (removing the car seat for a total scrub down and vacuuming did) and it does not kill ants on direct contact. Even with the product spray directly on them, they are still alive and then eventually die. It leaves behind a very greasy residue and a strong pesticide smell.

Great natural product

I received product reimbursement in exchange for my honest review. Having fruit flies in the summer months has been terrible, but STEM has helped eradicate that problem. I love that it is a natural product and doesn't have a bunch of chemicals I can't pronounce

Proven Effective!

[This review was collected as part of a promotion.] I'd like to start off by disclosing that I received a sample of this product, for free; from Influenster, in exchange for an honest review. With it being extra hot in LA this summer, we've had a few more flies than we normally do. Therefore, they're getting into the house more every time someone opens and closes the door. The ants were dead quickly after contact. It smells kind of nice, not unpleasant. The things I like about this product -- made of botanical extracts, safe to use these ingredients throughout your home. No added dyes, fragrance or harsh chemical odor. It also says it's safe for use around kids and pets! That's a win!

My only complaint!

The bottle says use as directed, but there are no instructions on the bottle. It worked great but I did not no to shake it or to wipe it clean til I searched and found the site. Love that it is safe for pets, as it was my cats bowls that have been the major target.
