The product appears to be an effective insect killer that successfully eliminates a variety of garden pests. Many users report it effectively controls insects like Japanese beetles, ants, fleas, and ticks, with fast-acting and long-lasting effects.

The BEST THING EVER!!!!!

Would Recommend

I hate bugs. Stink Bugs and ants are the worst invaders and I would do anything to never see one again. I found Sevin Concentrate and bought a sprayer. I was living in a house next to a herd of cows and there were ants everywhere and every kind of bug imaginable. The ants were coming in...there were dead stinkbugs everywhere in the house (I moved in during the month of April when they are trying to get back outside and dying) and the outlets were infested with ants as well as the rotted broken f...

Great for Fire Ants here in F.L. it's on contact though

Would Recommend

It took about two days to completely rid the ant colony the 2nd day they were still squirming my only concern is the bigger bugs like beetles got spray on them and the lizards ate the bugs, now I don't want to start killing my geckos so that was my only worry and I tried to catch the lizard but he ate a huge bug with spray all over it.

Used all season and has no effect

Would Not Recommend

I have used this product since March of this year and have had mo luck with it. Aphids, white flies, and spider mites just keep coming in masses. Use it at least once a month as well as spot treatment. I have used the comcentrate as well as the dust. Does not even kill ants. Have spent upwards of $200 this year in hopes due to how many recommend it. I would highly appreciate my money back.

Awesome bug killer!

Would Recommend

First time I sprayed killed black widow spiders and other spiders quickly! Dead bugs are showing up everywhere. Don't know why reviews would be negative. If you have a bug problem will work! I used it and works!

Used on my tomatoe and bean plants as well as peppers.

Would Recommend

Here in Texas, there are many kinds of insects that like to eat veggie plants. I used sevin liquid on all, killed all of the bugs. My plants look great. I'll be using again and again. My dad and grand pa used sevin as far back as i can remember. They swore by it. This is a safe and effective product when used as directed. I would highly recommend it to anyone who needs insect control in garden and / or yard. Keep up the good work Sevin.

Waste of Money

Would Not Recommend

I used Liquid Sevin for years and always had great results. The last couple of Concentrate I have purchased are worthless and a water of money. Why did you have to ruin a great product. Make cheaper sell for more greed? Thank you for ruining s great product.

Does not even kill bugs at all!

Would Not Recommend

We bought some from our local co-op and when mixing the concentrate was very watery and didn't even have a smell. Sprayed on garden for beetles and it didn't even phase them. So we thought it was old so purchased at a local rural king and sprayed again and nothing. We triple dosed it on our potatoes for tater bugs and sprayed and it didn't even phase them. The bugs have literally about eat all our vegetables up this summer. We have never had a problem with Sevin and always used it but it's not w...

I will purchase seven products again.

Would Recommend

I use the bag granules for the lawn last couple years and wipes out ticks. I use the liquid in my vegtable and flower gardens, and works great usually only have to use once. The only problem I have is with the ready to use that attaches to water hose. The sprayer doesn't work right so I won't purchase again, inless company fixes. Would be easier to use then the concentrated. But for now I'll use the concentrated.

Fairly easy

Would Recommend

[This review was collected as part of a promotion.] The container comes with its own measuring cup in the lid. I normally use the dust, but it doesn't seem to last as long as the liquid does. So far, no squash bugs. Most produce is fine. We've just received so much rain recently that spraying has been futile. Hoping for a squash bug free summer, though!

Works Great

Would Recommend

[This review was collected as part of a promotion.] I received Sevin Insect Killer Concentrate free for my honest review. I received this product at the perfect time. With the weather getting hot I needed something to kill mosquitoes, ants and other insects that I started seeing around the house. This product was easy to use. I spread it around the outside perimeter of my house and I am no longer seeing the bugs. It only took a couple of days for me to see the change. I will continue using this ...

Keeps the bugs out

Would Recommend

[This review was collected as part of a promotion.] I use this Sevin Insect Killer Concentrate to keep bugs out of my house. It's a concentrate so it has to be diluted in water in order to use it. I spray this product around the perimeter of my house so that bugs will stay far away. Since using this product, I haven't seen and indoor insects. I like to use this after a good rain. It works great!

Works great!

[This review was collected as part of a promotion.] I just started using these on my plants and so far so good. It seems to be keeping the bugs from eating my plants. Definitely will continue to use and hopefully it will keep working. It's easy to use, just mix and spray.
