Sevin insecticide review
This Sevin insecticide is effective and highly concentrated insecticide that is able to kill more than 100 different pest species (full list of Sevin insecticide target insects here) and will leave your outdoors space insect-free for several days.
The reason why this particular insecticide is so efficient is the active ingredient that is blended with all the other ingredients that make this insecticide what it is. This ingredient is called 1-naphthyl N-methylcarbamate or Carbaryl for short. It is a carbamate family chemical that was introduced in 1958 and now is mainly used as an insecticide because it is highly effective at killing all pests, unfortunately, including honeybees and other beneficial insects as well as most aquatic invertebrates. And because it can be toxic to humans if inhaled, swallowed or absorbed through the skin, it should be used only outdoors.
Since this Sevin spray insecticide contains only about 22.5% Carbaryl it also can be used on vegetables, fruits, and gardens because it will effectively kill insects that target them, without seeping through the fruit or vegetable skins or penetrating their tissue and poisoning them or making then inedible. However, it is still recommended to rinse the fruits and vegetables thoroughly before eating, it they have been treated with this or any other insecticide for that matter, to make sure you don’t eat any remaining particles of the insecticide.
One of the greatest things about this particular Sevin insecticide is the bottle that it comes in. It is specially designed so that it is easy to dose the appropriate amount of the insecticide into a gallon of water without there even being a chance that you have to touch the insecticide. Use up to 1.5 ounces (44.3 ml) of the insecticide on 1 gallon of water depending on how insect infested your outdoor area is. And because you have to use only a small amount of the Sevin insecticide each time, even the 32-ounce bottle will go a long way and last you a long time.
The recommended application options for this Sevin insecticide are either with a pump style sprayer, dial-style sprayer or concentrate plus water hose-end sprayer, because these types of sprayers will ensure that the insecticide will be evenly distributed and applied in thick enough layer, so that it is actually able to kill all pests that it comes in contact with. But you can also try to use the insecticide-water solution with a cold fogger turned on largest droplet size, so the insecticide doesn’t vaporize without getting to settle on your sprayed area.
Because the insecticide is broken down by environment quite easily, make sure that you apply the insecticide in fairly calm weather without a lot of wind and defiantly without any precipitation. You should also try to get at least 24 hours of no precipitation period after the application of this Sevin spray insecticide, as that will let the insecticide thoroughly dry and take effect, allowing it to last longer. And remember to shake the insecticide solution before use, to make sure it has mixed with water because even though it is a water-based insecticide, it can still not mix properly if just added together without shaking.
Also, you should wear gloves, long clothing, protective glasses and respirator if possible, as they will protect you from inhaling the insecticide solution or it coming in contact with your skin, which can cause a severe allergic reaction. And make sure at least 7 days pass before you treat the area with the Sevin insecticide again because that will give time for the treated area to breathe a little and the insecticide to break down enough for the environment to be ready for spraying again.

Summary
This Sevin insecticide is one that not only goes a long way, because you need to use no more than 1.5 ounces of the insecticide concentrate on a gallon of water for it to be very efficient, but it is able to kill around 100 different insect species and will last up to few weeks depending on the weather conditions, letting you have insect-free outdoors space to enjoy. So don’t hesitate to choose this Sevin insecticide over other similar ones.
Is there a way to use Sevin to deter wasps from taking over my 3rd floor balcony? Sevin is an effective insecticide for gardens & lawns, but is it ONLY for use on plants?
I need to reclaim my balcony. Other than wasps, the only thing on my balcony is a stationary air conditioning unit (exposed) and the air intake vent to the forced air unit. No plants. I can’t use my balcony at all because wasps take it over & keep control. I need a way to get rid of wasps without poisoning myself! What can I do???
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!
I’m tired of cockroaches in my house what is the best insect killer to get rid of cockroaches.
Hi Collins,
I am not an expert on insect killers that kill cockroaches, however, from what I can tell the Advion Syngenta 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
Will seven kill walnut husk fly
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.
Will seven dust kill black ants
As long as the are not harvester, carpenter or Pharaoh ants, Sevin should work on them.
I need to get this out there. And I am going tostart here. Yes I always use as directed. 7-Dust and 7- Concentrate does not work on anything it states it is suppose to work on here in Yuma, AZ. I spent years in Michigan and it was always my first choice. Never again. What ever bugs are on the lable. It does not get rid of them, I am so dissappointed.
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.
WILL THIS KILL TAWNY ANTS/CRAZY ANTS.IF SO,HOW DO YOU KILL THE NESTS SO THEY DON’T COME BACK.
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.
Does it kill Crane fly (Leather jackets) which part of the grub family ?
Sevin should kill Crane flies, when they come in contact with the product.
will this kill ticks and fleas and if so for how long
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.
Does Sevin kill fire ants? And can I put it directly on the fire ant colony mound?
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.
It would be nice if Sevin provided a list of plants that are phytotoxic with Sevin. Sprayed a greenhouse full of flats of small plants and Sevin burned a lot of them and stunted others. Very unhappy with this product. I deliberately didn’t use Neem or Insecticidal Soap because of the oils in those; was not aware Sevin is an oil. I thought it was water soluable like Spinosad. Lesson learned.
Sorry to hear that, Norm. Indeed lesson learned. Hope you manage to rebuild your greenhouse garden.
Will Sevin kill aphids(sp) . Can it be used on Sucullents?
Karen
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.
I bought the “Sevin” insect killer ready to use, 1 gallon pump spray for $17.21 at Tractor Supply. Followed all directions by reading all directions, then shook the container gently and proceeded to spray my prettiest flowers.
Within 15 minutes all the flowers and leaves sprayed had turned brown, curled up and died. I was so appalled……….could not believe my eyes!
After about an hour, I sprayed a few more plants, mostly wild flowers…..and much too my sadness and anger…………watched them curl up turn brown and die!!!!!!
Not finding ANY phone number anywhere on the directions for Sevin headquarters, I brought the container back to Tractor Supply, along with a bag of the murdered flowers. They promptly refunded my money……………and said they would remove all products remaining on their shelves.
Cannot believe how deadly and powerful this is and wonder WHY it is even on the market!
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.
this stuff is crap. the dispenser stopped working, and it burned the leaves killing my garden.
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.
