    Works(slowly), but too many downsides

    Leaves greasy residue. Does not dry fast. Smell is overwhelming. Somehow the outside of the can seems to be coated in it. Every time I use it, despite washing my hands numerous times, and my face, I get tingly sensations in my fingers and around my eyes even if only a small spray was used and well away from me.

    Hate

    I really hate this stuff. The smell is quite strong. Strong enough that pets, children, and adults will vacate the premises even quicker than the bugs. It smells like cancer. The oily residue is a pain to clean off of any surface. It stained my wall in a very obvious way. I used the product twice to give it a fair shot. The spray upset me more than the bugs ever did. I put the remainder of this product in the garbage, as it is obviously trash.

    Very Greasy

    Not what I expected. It leaves your walls and floor so greasy, and the smell gives you a headache. It leaks while you’re spraying it. I needed to use a lot of amount to kill the ants .

    Works on fruit flies

    I bought this about a year ago to have on hand especially if I get an army of ants again. I don't get any 'bad' spiders and only catch & release daddy long leg spiders sending them back outside. But this spray works great including fruit flies & any bugs or roaches. I use it sparingly.

    A must have!

    It works wonders for us ! Instantly killed the roach among contact ! And by morning everything was dead! I would absolutely recommend it. The smell is strong but worth it since it’s eliminating the bug problem the residue it oily so we spray at night and in the morning When cleaning up we wipe everything down! I have 3 young children and it does not seem to bother them at all.

    (no review title)

    This worked great on those waterbug roaches we get in the summer. It does not work on contact it takes a min but so does raid so I dont know why everyone is complaining. It stuns them then takes a min for them to die but they do. Everyone is also complaining about the smell. Yes the odor is strong especially if you use a couple squirts which kills bugs faster but you are SUPPOSED TO CLEAN AREA you sprayed with Soap and water after!!!! If you do that and open a window the smell goes away quick. I think this works great and the fact it is safe for pets and kids is a win win!

    Not effective

    I’m disappointed in the stem insect spray. While it’s pet friendly it has a strong smell and leaves an oily mess behind. It basically drowned the ants and did not keep them from coming right back.

    We're so sorry to hear about your experience. Excess product can be wiped away with soapy water. As this is a contact spray, insects need to be sprayed directly as this does not offer residual action. That said, our team is here to help.

    Kills roaches

    This kills ants, but more importantly cockroaches! And on the spot! As soon as I sprayed it on the roach, the roach did not run because of the poison. Though it did not die instantly, it was not going anywhere. I swept it up and flushed it down the toilet since it was big and I didn’t want to smash it.

    Works well. Spray the ants, it slows them down and you can then smash them. I've yet to see if it keeps them away. Smell stays forever.

    Ineffective on spiders

    Spiders are refreshed by this product. I did a continuous spray on several spiders for more than 10 seconds. They did not budge. They almost seemed to be laughing or one might see their reaction as them enjoying a glass of wine at the end of a long day. They were CHILLIN!! It’s garbage. I’m going to see about returning it.

    Does Not Work!

    Overwhelming strong scent. Doesn't work on roaches. After spraying on them, they just keep moving. Not sure how long it takes for this product to work, but it's now been 10 minutes and the roach is still moving.

    Ruined my floors

    Do not use this! It ruined my polished concrete floors. I bought this versus the other brands because it said it was safe to use around people but it ruined my polished concrete floors. It would probably ruin wood floors too.

    It doesnt kill the spider immediately

    I used this to kill a spider on the ceiling. It did reach the spider which was like 2 feet away. However it knocked the spider to the floor and it was still moving although with difficulty. Eventually it froze up and although it was still alive it wasn't moving places just movint it's legs. While it's organic it does have a bit of a scent although it's not unpleasant. It might just be better to use raid cause that actually worked for me to kill a roach and it didn't smell bad. Overall it seems to stun the spider not kill it you have to do it yourself.

    SKIN IRRITATION!!!!

    1) I got a very severe ear dermatitis using this spray trying to kill ants. I woke up next morning with a huge rash on my ear. (After doing research, it is a side affect from using this spray) 2) Does not work! I was spraying the ant and the ant was literally still walking around soaked in the spray! Windex works better than this so called ant killer!
