What Customers Are Saying

Customers report mixed results, with most praising effectiveness against Japanese beetles, ants, stink bugs, aphids, spider mites, and caterpillars, noting visible results within days and protection lasting up to 90 days. However, many express frustration that the formula no longer works as effectively as before, with pests persisting despite proper application. Some report plant damage including blackened leaves and wilting, while others note the product washes off easily with rain, requiring frequent reapplication. Overall, reviewers remain divided on whether current performance justifies use.

Buy it and use it

Would Recommend

Live in Ohio and at this summer season (July) the Japanese Beetles were destroying newly grafted apple trees, raspberry's and blackberries. I tried two insecticides I had labeled for use on these plants. They kill exposed Japanese Beetles but the next day they were back in the dozens eating leaves and mating on all the plants. I was told Liquid Sevin should be tried. I bought some, mixed it in my sprayer and applied it according to directions. Exposed beetles were dead in about 10 minutes. Today...

This product is a total joke Japanese beetles grow larger

Would Not Recommend

I mix in 25 gallon spot sprayer at an extreme rate of 4 oz per gallon of water. Beetles love the bath it gives them. I would strongly recommend Bayer stop lying to people that this products controls Japanese beetles.

Great on Plants, HORRIBLE for lawns

I have used this product for years on my plants and it has worked awesome. This year I decided to treat my lawn with their lawn product and I had more insects than I did before I used it. Absolutely horrible. I gave it a 3 as the plant product is awesome but lawn is not worth a lick!

Used for a Lantern Fly infestation.

Would Recommend

I used the Sevin that connects to the water hose. Was extremely easy to use and easy to view how much is in the bottle because the water stays out of the bottle. I covered a large area. The Lantern Flys were killed in a couple of minutes after contact. 1,000's were scattered across the ground in minutes. I highly recommended. Also after spraying my tree added a sticky tape with screen over it to protect the birds and it is also working well. I simple not costly way to help combat Lantern Flys. T...

I've been using Sevin for 35 years

Would Recommend

My parents used it before that. All these people who say it doesn't work must be using it wrong.

Nope

Would Not Recommend

I used a hose sprayer, we have a lot of Spittle Bug. I sprayed 4000 sq. It seemed to knock the bugs down then three days later they are starting to show up, the bugs and the nymphs. Bubbles and all. What a waste of time. I'm trying to save my $3,000 front yard.
