    • Super Effective Ant Repellant!
Scent: Unscented Size: 12 Fl Oz
Cannot say enough good things about this spay! We have struggled with ants for years in our old farmhouse and this is hands down the best ant replant product I’ve ever used. The scent is a bit strong immediately after application, and it can leave a bit of a greasy residue if you don’t wipe it down after spraying, but all things I’m willing to deal with in exchange for how well it works. I waited a few weeks before writing a review to see how long it would be effective after applying, and so far so good! I have not had to reapply to any of the areas I’ve treated thus far and have not had any issues or any colonies return. I will absolutely be a repeat customer! ... show more

    • It works
Scent: Unscented Size: 12 Fl Oz
I don't like the smell at all. Certain scents bother my nose. But having water bugs and I started seeing a few roaches here and there. Hadn't seen roches in over 15 years. But there are new neighbors and since then new roaches They moved in rent free. The neighbors who have bug phobias are hysterical. Funny to me but whatever. I wanted to try this because it's natural but I really dislike the ordor it leaves but it works great!! Warning it's not a spray that dries up. I spray under the sink cabinets and it's a bit greasy. I have to clean up after a dew days. But I rather do this than have them running around having more critters. Also if you spray directly on a water bug or roach. It kills them instantly. Good stuff. ... show more

    • Great product, a little strong on the odor.
Scent: Unscented Size: 12 Fl Oz
Works great. A little oily & the smell is a bit strong, so if your sensitive to odors, vent well for a couple hours.

    • Top Notch
Scent: Unscented Size: 12 Fl Oz
Was hesitant on the effectiveness of this product, but WOW does it work, quickly and effectively. I have pets like the fact it's not toxic. smell is strong at first but of an herbal oil goes away if left out in fresh air. No sign of pests

    • Works Great & Safe Ingredients!
Scent: Unscented Size: 12 Fl Oz
I’m very impressed with this bug spray! The quality is excellent—it’s effective yet made with plant-based ingredients, which I love. The price is reasonable for how well it works. It arrived in perfect condition, securely packaged with no leaks. The effect is fast—I’ve used it on ants, roaches, and flies, and it gets rid of them quickly without a harsh chemical smell. Great for both indoor and outdoor use. Highly recommend! ... show more

    • STEM for Flies, Roaches, & Ants, NOT what I want!
Scent: Unscented Size: 12 Fl Oz
If you heed to kill bugs,, don't rely on this product! I had a sudden infestation of not only roaches, but tiny, biting ants, & drain flies! The product DOES kill the bugs, but has no residual effect per the company. I believe it actually has SOME, but very short-lived. I need a product which continues to kill after it is sprayed on surfaces! This product is not to be used on porous surfaces either like bath mats, throw rugs, underneath cushions, etc where bugs hide. Also do not use on floors b/c it is a slip/fall danger. The product is oil. I do not have the time nor the energy to sit & spray each & every bug as they appear, nor can I be in multiple areas at once! Plus, it uses a LOT of product to directly spray every bug! That makes no sense!! Well, not for the consumer, but makes much sense for the company coffers! So, no, in my opinion, 1) it isn't so easy to use, 2) it is not worth it's cost in the long run, & 3) the fragrance is very strong & somewhat unpleasant to me. In fact, the 1st time I used it was in my master bathroom, the main area bugs congregate: I got an instant headache & mild nausea which grew as time went on b/c the scent was so strong it reached my bedroom! The scent lasted for about an hour, the discomfort lasted hours. This effect seems to have diminished in severity over time, but remains unpleasant. I am very disappointed by this product & will not be buying any other products made by this company...unless they change them to have lasting effects. I do not recommend it unless you have only a few bugs, but as we know, especially w/ roaches: for each one you see there are likely more than 100 you DON'T see! ... show more

    • This actually works (on earwigs too!)
Scent: Unscented Size: 12 Fl Oz
I don't know what happened this year, but suddenly my house was the meeting point for every earwig in the neighborhood. I mean, they were crawling on my screen door in waves, if you picked up anything outside at night, there was a mat of them - there were literally so many crawling on my hosta stalks that they were bending over. It was gross. Some even made their way into my basement window wells and got in the window down there. Absolutely not. I've tried a few ant killers here and there before, they usually smell foul, don't really last, and are expensive. This product was none of that. It does have a smell, but it's not that strong or awful. It lasted about 4-7 days per application around my sliding doors and the window wells. Obviously it lasted a bit longer with inside application than outside, but the fact that it lasted outside at all is high praise against other products that do not at all. It also seems to kill both ants and earwigs on contact as well as repel them (I live in the woods with a high humidity level, so we get roaming carpenter ants too, and this worked on them as well). It's a bit oily, but I didn't have any issues with it staining bricks, stone, or the white painted trim I put it on outside. It sprays very fine, so it doesn't take a ton to cover a decent area. Also, my dogs and cat had no issue with it, which is great. Since I was spraying it liberally on the threshold where they do into and out of the yard, they came in contact with it to some degree, and they had no issues with it. They didn't even sniff at it. I have a degree in Chemical Engineering, so I'm definitely not one of those "omg chemicals are bad!" people that avoids all pesticide or only buys "natural" things, but I bought this on a whim on sale and highly recommend it. Works AT LEAST as good as standard commercial ant killers like Raid for sure. I will 100% be buying it again next year. ... show more
