Reliable, Long-Lasting Defense Against Bugs
By Alex on Reviewed in the United States on August 1, 2025
After dealing with a steady stream of ants and spiders around my home, I gave this insect killer a try—and it has completely exceeded expectations. I applied it both inside and along the exterior perimeter, focusing on common entry points like baseboards, doors, and window frames. Within a day, the pests were gone. The comfort wand makes application simple and mess-free. It’s especially helpful if you want to avoid bending or getting your hands near surfaces. The spray dries quickly, has no lingering odor, and doesn’t leave behind any visible residue. It’s ideal for indoor use, even in high-traffic areas or homes with kids. One of the best parts is the long-lasting barrier it creates. Weeks later, I’m still seeing results without needing to reapply. Compared to sprays that require weekly touch-ups, this one saves time and effort. For added peace of mind, I appreciate that it works just as well on outdoor pests like mosquitoes and flies, especially in areas near moisture or vegetation. Whether you’re battling bugs seasonally or year-round, this is a dependable and cost-effective alternative to hiring an exterminator. Highly recommended for anyone wanting an easy, effective solution. (Great for spiders)

Short term review…..Edit drop down to 3 stars
By ChomChom on Reviewed in the United States on July 29, 2023
So I used this like last week to get rid of spiders by my window. They keep setting up shop there. I went back today and sprayed again, expecting them to be back. Because that’s the usual for when I spray some repellents. After it dries, their webs are back up. But it wasn’t even one spider there. And it was some big ones before(california big. Not Australia). So I didn’t fully spray. Just one area but I quickly realized no spiders so I stopped. So this is a short term review. I’m going to set a reminder in my phone to check it in 3 months. I know it is advertised to last longer. But I want to check it at 3 month intervals, to see if it’s still working. Of course if it rains, the experiment is over lol. So I’ll come back in 3 months for an update. Mid Edit: As of 09/10/23, there’s still no spiders. And there are no huge spiders around where I live. Like a tarantula, wolf, or huntsman. Not that I’ve seen at least. This is a spider repellent review. Not a flamethrower review lol. And it rained from the hurricane/tropical storm that passed recently. I guess it didn’t hit the area directly or it wasn’t enough to wash it away. So that’s good it lasted this long. I’ll come back near the end of October for one final update. But I’m already sold with it lasting over a month. 10/23/23 Final update. Still no spiders outside my window. So it works for at least 3 months, which is good for me. One thing, don’t spray it in high bug areas like outside trash cans. I sprayed my outside trash cans because I don’t like touching spider webs when taking out the trash. Next time I’ll just spray the handles or something. Because there were so many more flies in and around the trash after there were no spiders left around there to catch them. So just be mindful of that. AND, it didn’t repel the flies. So it worked for spiders, not for the house flies. Edit: 05/05/2024 I had no intentions of doing another edit. But I was so impressed I had to. I went out to spray my window again just now. And there were no spiders or other insects where I sprayed. No spider webs or anything. After rains, winds, time, and it’s living up to the claims so far of being long lasting defense. I just thought that was cool. This is the last update though. Because I sprayed it again even though it wasn’t needed. I was trying to see if a spider would come running out from where I couldn’t see it or something. lol nothing ran out. I wish it worked better for flies. But this is a must to keep handy if you deal with a lot of spiders. Oh. Side note. It hasn’t messed up my paint either. But this is a case by case basis. Do a spot check on your intended surface to test it first, if concerned. Ok. That’s all. Thank you for reading. Have a good day edit: June 1, 2024. I sprayed in the doorway because spiders kept going there. They would come every couple of weeks. I sprayed and within 2 days I saw 3 spiders right where I sprayed. Didn't phase them at all. The daddy long leg ones. Not sure why it works so well for the outside spiders and not for the long legs. But hey. If I had to choose which spiders I wanted to stay away, it's definitely the ones outside. still disappointed though.
