Sevin Insect Killer Insecticide Review

Hi Rosemary,
As far as I know, yes, Sevin is effective against wasps. However, the label of the product says that you shouldn’t use it indoors, so I am not sure if this treatment would be the best course of action for treating your balcony, which is adjacent to your apartment. I would recommend you to look into other insecticides, that might be a bit more efficient in your case. I can advise you to check out the EcoSMART Wasp and Hornet Killer or Prescription Treatment Pressurized Insecticide.
Hope this helps!
Best,
Karen

We have used a “waspinator”, a fake wasp nest, with success. New wasps are intimidated by an “established large nest”.

Thanks, I’ll try that!

Hi Collins,
I am not an expert on insect killers that kill cockroaches, however, from what I can tell the Advion Cockroach Gel Bait and Rockwell Invict Gold Cockroach German Roach Control Gel Bait are some of the most efficient products on the market for this purpose.
Best,
Karen

Terro brand roach and ant liquid baits work awesome. So does that roach gel that you squeeze out along base of your walls and baseboards. Get both of these for a one two punch to get rid of roaches. Also get rid of any cardboard boxes in your home as the glue in those boxes attracts roaches.

Although the label of the product doesn’t specify that it kills Walnut Husk Fly, since it kills so many other different insects, including other fly varieties, then I would say that it might work on Walnut Husk Flies as well.

As long as the are not harvester, carpenter or Pharaoh ants, Sevin should work on them.

Sorry to hear that! It’s interesting, though, how it worked for you in Michigan and how now it doesn’t work for you in Arizona. I would recommend for you to try contacting GardenTech, who manufactures Sevin, maybe they will have an idea why it is so.

Read the label carefully. You want to use the one that has Zeta-Cypermethrin – 0.35%. I use it at 1/2 strength and add some neem oil. VERY EFFECTIVE!

I sprayed this on all my herbs in my patio planter including Basil because I have a problem with earwigs eating holes in my Serrano peppers as well as my Basil at night
Is this harmful for us humans ?

You should check the label to see how long after the application you have to wait for each specific herb. The time is different for different types of plants. For example, peppers shouldn’t be treated within 3 days of harvest. The product shouldn’t cause any harm, as long as used according to the label.

Sevin should kill Tawny crazy ants. As for how to kill ant nest, unfortunately, I am not an expert in this, so I can’t really help you in this matter, but there are many great resources on the internet that do explain how to make sure that the ants don’t come back after treatment.

Sevin should kill Crane flies, when they come in contact with the product.

It definitely will kill Ticks and Fleas! And it should work for several weeks, as long as you let the product dry for at least 24 full hours.

Sevin does kill fire ants, yes! The only ants it doesn’t kill is harvester, carpenter, and Pharaoh ants. And although Sevin is intended to be used as a perimeter treatment, I believe you can apply it to the fire ant colony mound. Although a better practice would be to spray Sevin on the area around the mound because this way it is more likely that the ants will come into contact with Sevin and be killed by it.

Can Sevin spray be used safely on collard greens?

As for Collards, the label suggests you shouldn’t use the spray 1 day before the harvest. Also, make sure to always check the label and follow all the instructions mentioned there!

Sorry to hear that, Norm. Indeed lesson learned. Hope you manage to rebuild your greenhouse garden.

Yes, Sevin should kill aphids. And I don’t see a reason why not to use it on succulents if it can even be used on veggie plants.

So sorry this happened to you and your flowers, Susan! You should contact GardenTech, who manufactures Sevin, about this and make sure they are aware of what Sevin did to your flowers.

So sorry to hear that, Jose. Lately, there have been quite a few mentions of Sevin burning plants and killing them, so I’d recommend you contact Sevin manufacturers (GardenTech) and voice your concerns to them since we are not responsible for formulating or manufacturing the product.

The label of the product mentions that Sevin does combat the Pine and Spruce Engraver Beetles among other common pine tree bugs. However, the manufacturer also doesn’t recommend that you apply this product to trees taller than 10 feet. Sevin should mainly be used as a spot treatment for pest infestations on trees. For further clarification, I’d recommend you to contact the manufacturer directly.

Check out our article on top termite sprays. Most of the products listed there can be used not only on termites but on carpenter ants as well.

The manufacturer says that the Sevin concentrate can last up to 5 years provided that the bottle is kept out of direct sunlight and the lid is screwed on tight. So your bottle should still be good. Just shake the concentrate before using it again.

No, the granules will likely not dissolve.

No, most insecticides will have trouble dealing with eggs.

Was the product new, or was there a chance it might have been expired? You also have to make sure you used the right proportions when mixing the product (as provided on the label). Also, how long did you wait to see the results? Cause it won’t always happen immediately.

I’m not sure about beach sand specifically, but I assume it might be safe for kids later on, considering it can be sprayed on fruits and vegetables. Though, keep in mind that the product is extremely toxic to aquatic invertebrates, so you should never let it get into the water.

Sevin Ready-To-Use 5% Dust isn’t meant to only be used outdoors, so one probably shouldn’t use it on carpets or anything else indoors. As for the fleas themselves, you should recommend your friend our article about getting rid of them. Good luck finding the best solution!

The label does say not to use it more often than once every 7 days. To get a better understanding of properly using the product, you can find the label in this article, by clicking on the link at the beginning of the review. However, we’re glad the product has proven itself being useful to you!

We would suggest disposing of the product. There’s a chance it’s still good to use, however, since you’ve stored the product in conditions other than the ones given by the manufacturer, the product might also be damaged and unfit for use.

Couldn’t find it on the label specifically. Generally, the label has stated the product to be safe for use on many plants, therefore, your palms most likely would be fine. However, there have been complaints about the product burning the leaves of plants, so it might not be a bad idea to contact the manufacturer.

It might take a while for you to get rid of the bugs, as well as you might need to repeat the treatment.

The label doesn’t specify Columbine sawfly specifically, though, it’s worth a try.

Sevin is an insecticide, therefore, aimed at killing insects. If you’re dealing with mice, you should look into some rodenticides.

Have you seen the insects? I think you might be dealing with pine weevils. The product is labeled to be used for them, so it should help you fix the problem.

The shelf life is approximately 3 to 5 years, so it’s possible the product will not be effective anymore. You can also try contacting the manufacturer to get a more reliable answer.

The label suggests reapplying if insects return, but not more than once every seven days and according to the pre-harvest interval.

We suggest waiting for 24h so the product can dry. Also, don’t use too much pressure when watering your veggies.

You should check the label for specific advice depending on the type of vegetables you’re about to plant. Usually, the product can be used up until a certain amount of days before harvesting the plants.

A specific time is hard to say, as it might depend (we suggest at least 12 hours, perhaps 24). Make sure it has dried, though.
