Will definitely continue to use!

I received product reimbursement in exchange for my honest review. I have 2 boys who are constantly going in and out of the house while playing and always forget to close the back door. During the summer, flies are a huge issue. I used this product and each one I sprayed instantly died. I did wait for each one to land on a surface before spraying, so they were doused in the spray. I love the way the product smells, especially since I will be using it inside. The only downfall is it did tend to leave an oily residue on the surface sprayed, but it isn't a huge issue since I disinfected the surfaces after wiping away the dead flies. I will definitely continue to use this product in the future!

Works great, safe for pets!

I received product reimbursement in exchange for my honest review. I love that this ant, roach and fly killer is safe for pets. I have a cat and I always try to find items that are safe for him. I also like that it has no fragrances because I hate using bug killers that smell super strong. I've been having ants come into my apartment lately since it's right by a bunch of plants since spraying this I haven't seen any.

BITING FLIES BYE BYE!

I received product reimbursement in exchange for my honest review. I really like this product. I especially like that it is pet friendly and safe around kids. The smell is little chemically, but overall it is tolerable, and dare I say pleasant. Being disabled, I especially like that the spray bottle is easy to use and not too heavy. I even like the clear packaging, so I can see how much is left. In addition, I like how effective STEM is, especially against those biting flies that tend to devour my legs and make sitting outside a pain! I will say that the spray tends to not wipe up super easy on the concrete, so you may want to use a little water on the concrete to dilute. (Always taking those extra steps for my babies). Oh, and the bottle is recyclable! All in all, I really like STEM. It does the job and makes me feel like I am taking care of the environment!

Less effective and damages plants.

I received product reimbursement in exchange for my honest review. I really wanted to like this product and find a more natural way to kill bugs in and around my home. I tested it by spraying one anthill and one ant trail in my driveway. After 4 hours the ants were still moving as normal in both places, after 16 hours some ants died but the majority remained. Word of caution: as the bottle warns, the spray can damage plants and it did damage my grass around the anthill. I would consider using this product to spot treat areas inside where my kids and pets play, but I don't think it is particularly effective on any larger scale.

This works wonders!

I received product reimbursement in exchange for my honest review. This is the best, safest, most effective multi insect killer on the market. It is quick and effective to act while treating bugs inside your home. It has no terrible odor that other brands tend to have. I feel good about using this brand of product around my children and my pets without risking harm. I will never use another brand going forward.

Great product!

I received product reimbursement in exchange for my honest review. STEM kills ants roaches and flies works great. I used it on a string of ants near my mailbox, they were dead within minutes. There is a slight odor to the spray, but similar to citronella so its pleasant for the short time you notice it.

So far so good.

I received product reimbursement in exchange for my honest review. The smell of the product is similar to other natural roach and ant sprays. I can't speak to how long it lasts at keeping roaches and ants at bay, but it definitely kills flies as advertised. The ingredients are pretty basic and similar to other products in this category. Definitely worth a try.

I am totally sold on this product

My apartment building is bring renovated (apartments) and they are shaking up some cockroach individuals. I have a cat and I need something that is safe. I saw STEM at a store and decided to try it. I love this product. Just two sprays and they died within 1-2 minutes. Great product!!!

Safe for pets

I received product reimbursement in exchange for my honest review. I love that this product is made with natural ingredients like plant botanicals. I have two cats and it's really important that the products I use are safe for them, especially since the ants I have noticed are close to their food dish.

so far, so good

[This review was collected as part of a promotion.] I haven't had a chance to try this on ants yet, since it is winter they are dormant. But I did use it on a spider that invaded by space. The spray bottle worked well and the product worked fast to where the slide died instantly. The smell of the spray is very herbal-y, so much better than the chemical stuff. I sprayed it on my laminate flooring and the surface was just fine after I cleaned up the dead spider/residue. I'm looking forward to using it this spring when there will most certainly be ants.
