    • Spiders hate it! Arachnophobes love it!
I'm glad this is seemingly non-toxic (enough) to pets as long as it's allowed to dry. While walking the perimeter of the house, spraying any spots that bugs might be able to crawl in through, I noticed something peculiar... All of our window screens on the first floor have a conveniently cat-sized hole ripped through them. It explains why I've found so many dang spiders in the house as of late, and why I have a seemingly never-ending supply of flies to swat. I don't mind the latter so much, mostly because of the satisfaction I get from it (stemming from my pure hatred of flies, as well as the 'thump' sound from hitting them mid-flight) but the spiders/webs left and right were driving me crazy! I don't wanna eat them in my sleep! As I went window to window, doorframe to doorframe, spraying a neat foam rectangle around each, I stumbled upon 2 (3?) different test subjects to help me see just how effective this product is. - Test subject #1: Jumping Spider Now, I really don't mind jumping spiders all that much. They're small, mostly stick to themselves, and curiously enough, I've never seen one weave a web. Alas, this poor laddie wandered right into my line of sight while I was treating the first window, so I gave it a go. I doused him thoroughly in the spray, and he didn't even try to jump! I would say he technically 'died' within a few seconds, as the last few seconds of movement were so minuscule, I doubt his spider-mind was able to comprehend much after the initial blast. All-in-all, it took the spray about 10 seconds to erase all signs of life from this almost-tolerable jumpy boi. Test subject #2: Demon-Spawn Tarzan (I hate this spider so much ew oh god gross looks so nasty) At the third window I went to treat, I walked through a web that got in my hair and face (I might buy the gallon next time) and I stopped to ins[p]ect myself (haha) for any spiders that might've got on me. Good thing I stopped and took a moment, because out of the corner of my eye, I see a little brown crawly boi swinging at me like the king of the jungle himself. I jumped back and gave him a tactical spritz (a tiny amount of fine mist, like a department store cologne sample) that undoubtedly made contact, but was so scarce that there was no visible sign of the spray on the demon afterwards. His nasty, evil legs started dancing like a madman, constantly stabbing at the air as if his last, dying wish were to give me nightmares and creepy-crawlies for days. I aimed the can to give him another spray as good measure, but before I even got the chance to double-dose him, he ceased - thank god. All-in-all, this nasty brown arachnid died in about 8 seconds after receiving just a tiny spritz of the product. Test subject #3: Satan's scavenger (winged feces-muncher) When I finally got to the shed, I was happily lining the corners with this wonder-foam when I heard a buzzing that was all too familiar, and all too close-by. A fly! He buzzed around stupidly in a 12-inch circle, making it easy enough to catch him in just a tiny bit of mist. This definitely bothered him, as he started flying more frantically, and charged towards me blindly a couple of times. Each time, he was met with another cloud of 0.03% Deltamethrin blasted in his direction. Now, being a fly and all, it was hard to tell how much of the product actually made contact with the ugly beast, but it's fair to assume that he got a slightly higher dose than #2 did. [The reason I marked #3 as (3?) is because this product was not marketed as a fly-killer, and I can't tell if it is effective as such. Besides, the can says to 'not spray into the air', so most fly-hunting with this product would be deemed irresponsible.] Sadly, I lost track of him when I stepped out of the shed for some fresh air, and was not able to locate him when I went back in. Did he die at my hands - er.. Spray? Or did he live to fly another few hours? The world will never know. I like to think he lived out the rest of his days getting rejected by potential dates all because of the funny smell I put on him. But that's just me. All-in-all, this product works great for killing spiders, and is cheaper than replacing your window screen every time your cat tears through it - Although it will probably not do much against mosquitos and flies; You need the ol'-fashioned zap-racket for those ones. The straw nozzle works great, and is so satisfying that I'm going to buy another can just for the fun of reinforcing my houses bug-barrier in another month! Will update then. ... show more

    • Foaming Ant Killer
Read the directions on the bottle. It worked today, in conjunction with another Ortho product. Did not have to vacate the premises, but did cover and remove all food items, and cleaned all food prep surfaces when finished. I also opened a few windows. Killed a lot of ants. Can use again in a week if needed. Was a bit pricey, but also effective. I was grateful it came packaged in good amount of sealed plastic, as it was shipped with another amazon item. Did not appear to have leaked. Grateful it is working so far. ... show more

    • Seems to work well
Seems to work really well but it goes really fast. They need a bigger bottle of it. This is good for one good coverage of a room in all walls in that room.

    • Actually works!
This stuff actually works! I encountered a critter someone frequently when I first moved into my place, but after one application of this along the outside doorframes and first floor windows, I haven't seen a single bug inside.

    • Need to spray quite a bit to kill
Review Image by Justin Wang Justin Wang
So, I just got this earlier today and my room got invaded tonight by another house centipede. I sprayed directly onto it and covered it in foam, but it still kept moving and didn't really seem very affected. I wanted to wait and see if the centipede would die from being sprayed, but I couldn't take it anymore and in the end, I killed it with my vacuum cleaner again like I usually do. I also sprayed it where my floor meets the walls and hopefully it'll prevent more bugs from popping up in my room. So far, I feel disappointed, but I guess I'll see if it lowers the amount of bugs I get. At the very least, it's nice that it dries without leaving a mark on the wall or the floor. Edit: Today, I got a spider in my room. I must not have sprayed the right area yet to prevent them from coming. Anyways, first, I sprayed the spider directly, and it kept moving, then I sprayed it a lot more, and it stopped and died pretty much right away. I took a picture afterwards to show how much I sprayed. I imagine for larger house centupedes, you'd have to spray even more to kill them. ... show more

    • Great for Crickets + Roaches
This is my second summer using and REE-ordering this product, so that should tell you something right there. I use it mainly for Roaches indoors and out, but it also takes care of other bugs like crickets. Last night I heard a cricket in my garage and sprayed a small line on the floor near where I heard the chirping. Tonight? No more chirping. It works the same with roaches. Now, don’t expect to spray it directly on a roach and watch it die. It doesn’t work like that. It seems to be more of a bait, and that’s exactly what you want with roaches so they can take it back to feed the others and eradicate them at their source. No smell, no fumes. I live in the Phoenix area where we get those big sewer roaches and they’re no match for this product. Love it! ... show more

    • centipedes
I never usually write reviews but i felt this product needed one. I was going just about crazy with centipedes getting into my apartment. It was just about every other day in the warmer weather months that I found them near my AC units or randomly crawling up the walls. I bought this product based on the reviews and tried it. I went from seeing one frequently to now killing one every like 6 weeks. I believe the product says it lasts longer than that before needed to be reapplied, but to be safe I now spray the cracks and openings monthly. I don’t know how safe it is with kids or animals, or really even for my personal health, but it works on keeping those nasty things away. ... show more

    • Worst cockroach spray
The media could not be loaded. I almost sprayed 50 ML on one single cockroach. It actually does a refreshing walk after the spray. Not sure if the company gives a medicine to kill roaches or a tonic to boost roaches. Could the manufacturer please respond me
