Harris Home Insect Killer, Liquid Gallon Spray with Odorless and Non Staining Residual Formula - Kills Stinkbugs, Ants, Roaches, Spiders, Fleas, Mosquitos, Moths, Scorpions, Flies and Silverfish

Someone suggested this to help with our out of control Asian lady beetle swarms. And it did the job!! Sprayed around garage doors and outside doors and windows. We couldn’t believe how many dead bugs there were within two days. It’s a little pricey, but it’s worth the money. The size is pretty generous, too. It worked so well our pest control guy said he was going to start using it.

I usually use Terro ant baits with very good luck if I can stand the ant trail for a day, but for some reason this set of ants was impervious to my normal approach. I didn't want anything too toxic in my kitchen, so I went with this because I could spray it across the Garden Window behind the sink and let it dry overnight and it woulnd't still reek in the morning.Pros:No smell. At least, none I could smell, but I did vacate after spraying and did not go back in the kitchen until morning.It worked. Better than I originally thought because the next morning I went into the kitchen and there were still ants. But 2 hours later, they were 100% GONE. And never came back. Here it is, two months later and they have never returned. That is unheard of, as I think this house was built on an anthill.....It was easy to clean off the back side of the sink with some 409 and paper towels (with a clorox followup because I am just that way)Cons:I wish I could have gotten it in smaller bottles. As it is, I had to pour it into a smaller spray bottle and label the heck out of it.Sprayer didn't work. That happens with a lot of things, but while trying to fix it, the bottle slipped, and then the sprayer was REALLY broken.The actual spray is wonderful, the packaging and sprayer, not so much. But in a small bottle, for indoor applications near windows and such, I'll keep using it.

Good product, but it does spit out a lot so I feel like I might’ve needed to. It is very expensive. I did have to go buy another brand to finish spraying but once it’s sprayed, there was no problem. It did not have a scent of pesticide or anything it’s easy to use really easy to set up once you push the thing in of spray

Kills Asian bettles and stink bugs too!

I purchased the Harris Home Insect Killer hoping it would solve my pest problem, but unfortunately, this product has been a total disappointment. After following the instructions carefully and spraying the entire gallon TWICE, the results were far from what was promised.1. Does Not Work as AdvertisedThe product claims to kill ants, roaches, spiders, fleas, and a range of other insects, but in my experience, it has done the opposite. After using the whole gallon, not only did it fail to eliminate the spiders in my home, but I now have more spiders than before. It’s as if the spray has attracted them rather than repelled or killed them.2. No Noticeable ResultsDespite being labeled as odorless and non-staining, which is true, the most important feature – actually killing pests – simply doesn’t work. I’ve tried other insect sprays that at least reduced the number of insects after a single use, but this product had zero impact. It’s frustrating to waste time and effort only to see the situation worsen.3. Low Quality and Misleading AdvertisingThe product description and advertising give you the impression that this spray will protect your home with a residual effect. However, after multiple applications, I saw no evidence of it working at all. It feels like the product’s promises are purely for marketing purposes and have no real basis in performance.4. Wasted MoneyThis product is not cheap, and for something that doesn’t work, it’s an absolute waste of money. I regret purchasing this insect killer and wish I had gone with a more reliable brand. There are far better options on the market, and this one is certainly not worth the cost.5. Final Thoughts – Don’t Buy This ProductIf you're looking for a solution to your insect problems, save yourself the frustration and skip this product. It is completely ineffective, and you'll likely end up with more pests than before. The time and effort I invested in using this spray have been wasted, and I can confidently say this is one of the worst insect repellents I’ve ever used.

The product help to remove the cock roaches, however it doesnt kill right away, or prevent the cock roaches too much. I sprayed it around the condo i rent and the new house, with the new house i spray around the cabinet and other pantry stuff, i still see some cock roaches around. I used the product outside to remove spider o ants doesnt seem to be too effective. My house have ton of ants crawling around and spider everywhere around the house.For cockrocaches i have spray like few times for the cockroaches to die. Even if i sprayed a few times at cockroaches, and look it dead, but few mins later i can see it crawl again. Im not sure whether the spray it really effective in killing cockroaches.

Works well

Update - It took 2-3 days, but the dead bugs have started accumulating to levels that indicate it is working well. It is not an immediate kill.Doesn't seem to be effective anymore for box elder bugs. I have tried this formula and the one specifically for box elder bugs. I had bought this stuff 2 years ago and the next morning there were 100's of dead box elder bugs on my roof. This time, there are just a few and they are still swarming all over my house.
