Yep, it's poison

Would Recommend

Used se7en concentrate on the entire outside of my home. From the perimeter of foundation around the house, soaked the shrubs, probably about head height on pine trees also treated the yard. It seemed to work pretty good for me. Years past you couldn't mow or do anything outside without a spider bite or some kind of pest bothering you. Now I treat my property about three times per year and maintain a mostly bug free environment. This stuff does have an oder till it dries and it does irritate the...

makes a mess

Would Not Recommend

Used to kill large group of red ants in my newly paved driveway. Mixture is milky white and left a large white spot. Tried twice to powerwash away. Still there. Maybe state DOT can use it to line roads. Don't use where you don't want to look at it every day. I now have white ants instead of red ones!!!!!!!!!!!!

Not as concentrated as they claim

Would Recommend

Been using Sevin under various names for a few decades. Usually the powder in a panty hose in the garden and on the dig when I was a kid. But you talk about how a little goes a long way. Then say 4 ounces to a gallon of water. But you leave out the part of the equation. How much area does that cover? A 10' X 25' area. You can put 4oz in a quart or 10 gallons, but the area it covers determines just how concentrated it is. 250 square feet needs 4 ounces of product. Would you please make that infor...

I used the Garden Tech Sevin Dus liquid concentrate

Would Not Recommend

I used it my small garden on my cucumber, tomato and squash tec and also my rose bush and other flowers. Every time I came across a big of any kind and I came across a lot of bettles, Grass hoppers stink bugs, worms you name it. They just stayed their and some moved from one place to another on the leaves and just looked at me and laughed or may me feel that way. I measured the right amount my husband watched me and shuck it and he pumped it. What was wrong!

Great product --- but

Would Recommend

We use it primarily to control squash bugs in our small garden. It works great, but I would NOT recommend the Ready to Use bottle that attaches to the end of a garden hose. I purchased two bottles thinking it would be super easy, but neither bottle will dispense product. As I said, it works great but go for the concentrate or dust and save yourself the headache.

Stains everything white.

Would Not Recommend

Sevin spray kills 100 insects. Also stains everything it gets on. No warning. Do not get it on your deck! Wood or Trex.

Need to be cautious of the pollinators

Would Not Recommend

I purchased this product because a lot of my Facebook garden groups recommended this product for my large infestation of cucumber beetles and squash bugs. I applied it last night, and 24 hours later I went to my large vegetable garden to look around. I did not notice one bug flying in the air or on my plants. It did rain all day and it's still dreary. However, I'm saddened because the only dead bug which I saw was actually a honey bee on one of the leaves of my pumpkin. I'll know more tomorrow, ...
