What Customers Are Saying

The insect killer concentrate is generally effective at eliminating a range of pests, including ants and Japanese beetles, according to many customers. The concentrated formula allows users to mix the desired amount with water and cover a large area, and the product is reported to act quickly, killing insects within minutes of application. However, some customers found the product less effective, particularly against Japanese beetles, and a few raised concerns about its potential environmental impact and issues with the packaging and measurements. Overall, the majority of users seem satisfied with the product's performance as a reliable and cost-effective pest control solution.

I would buy this again

Would Recommend

[This review was collected as part of a promotion.] Easy to use - just follow the directions. Will be interested to see how long this works or when we'll need to reapply, but so far so good.

The BUG Boss

Would Recommend

[This review was collected as part of a promotion.] I love this insect killer. It protects our apple tree's from all sorts of pesky tree eaters. I use it for multiple things consider I live out in the country. I use it to protect my roses from those Beatles that like to eat them and destroy them. It also protects the outside of our house from little intruders. It's very concentrated so it lasts a long time. You can use it in a spray that connects to a hose or a pump sprayer. This is the number o...

So easy to use!

Would Recommend

[This review was collected as part of a promotion.] I love how this is liquid and makes so much! It's super easy to use, much better than the powdered form. And it works so well!! I haven't seen any pests on my plants and they are thriving.

Great product; seemed to do the job

Would Recommend

[This review was collected as part of a promotion.] Product works very well for beetles as they've always been an issue. You should only use a small amount mixed with water as it's extremely potent. I find the best time (in my opinion) is right after a good rain and in the evening. This way the soil is already moist. Otherwise, there's the possibility of damaging your garden. I deducted a point because the design of the container left me rather annoyed. I prefer the old fashioned bottles.

Amazing bug killer

Would Recommend

[This review was collected as part of a promotion.] This bottle is small but mighty. This concentrate gets the job done and covers a lot of square footage. Goes on easy and really gets the bugs gone! I'm super impressed with this brand! Will be a repeat customer!

Works Great!

Would Recommend

[This review was collected as part of a promotion.] This is the only bug killer I buy, it works great on my vegetable garden and my flowers. As soon as I see the first leaf damage we get it out and use it. I never see bugs again just after the first use. The price is great and its sold everywhere I shop so it's a win win.

Sevin insect killer concentrate

Would Recommend

[This review was collected as part of a promotion.] I absolutely love this product. I have always just used water and soap in a spray jar to spray my vegetables in my garden and it works most of the time but we still have bugs. I use this product a couple of times now and I have not seen any bugs in the garden at all. I am so happy that I won't have to throw away any vegetables that we're half-eaten by bugs. I will be purchasing this from now on for my garden

Fantastic product!

Would Recommend

[This review was collected as part of a promotion.] I love gardening but I'm scared to death of bugs. This spray works so well. I started it about a week ago and I have zero ants and bugs on my flowers!! I'm so shocked. Usually my garden is full of insects but this did the trick. It also didn't harm my flowers. What I also love is that this is a concentrate so you get so much more for your money.

Finally! Something that works!

Would Recommend

[This review was collected as part of a promotion.] This you can use as much or little as you need - there's a guide telling how much for what type plant. I also learned adding a couple caps fulls to 2 gallons of water is sufficient to kill rather large ant colonies within 24 hours. I have had an ant problem for a few years now, and finally I have something that works!

Great for spiders

Would Recommend

[This review was collected as part of a promotion.] Sevin Insect Killer has been amazing so far. With it getting warmer here in North East Ohio the spiders that have been finding there way into my house is crazy. I have been looking for something that will kill them and also keep them away. We sprayed this insect killer all around the outside of the house and also around my basement walls. After a couple days I have noticed I haven't seen as many spiders and definitely found a ton of dead ones i...

Would Not Recommend

I tried product for the first time 1-2 weeks ago and it FAILED miserably!.....I have ants in my yard and following the listed directions, I applied your product accordingly...It made the "colonies" immobile for 2 days and then, they came back with a vengeance!....I then increased the amount over the next 1-2 weeks for each additional application of your product almost to the point of putting it on straight from the container and guess what?, even checking today 10-24-2018, the ants have gone no-...

Works for Lanternfly

Would Recommend

My maple trees were loaded with Lanternflies. In order to reach the high branches, I stood on a ladder and used the 32 oz bottle as the "soap" in my power washer, using the low pressure soap setting, The flies immediately dropped when hit by the spray. When they hit the ground they walked around a bit, more sluggish than usual. They started walking back toward the tree and started climbing back up, again more sluggish than usual. I was a bit disappointed. But then about 20 minutes later they sta...

Lanternfly

Works great on the lanternfly. Doesn't kill immediately but you can tell it's working. Once the lanternfly comes in contact they being to appear drunk then die.

Would Recommend

I have used this product for many years to treat fire ants. It has always done a wonderful job! However, I just bought a new bottle, mixed it in a gallon bottle as usual. The usual thing I would see is the liquid would be white when I treated the mounds. This new bottle pours out of the gallon bottle (when mixed with water) practically clear. I thought maybe I forgot to add it! But, I know I did. I did shake the concentrate and measure as usual.... Is it now almost clear when mixed? The liquid f...
