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.

Sevin InsecticideSince 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.
