Is Sevin Dust Safe For Plants?


Spreading Sevin dust over your houseplants or garden plants, lawn, and other places may deter insects and other pests.

Although some people put it on their lawns to ward off fleas and ticks, it is mostly utilized in vegetable gardens. However, since you came across this article, you must be wondering, is Sevin dust safe for plants?

In general, Sevin dust can be safe when used properly. However, pets (particularly cats) and people should wait until it has rained before going into areas where the dust has been applied. Sevin dust can cause toxicity if handled improperly.

In this article, we will discuss how to use Sevin dust properly to avoid any additional damage.

What Is Sevin Dust Used For?

A pesticide called Sevin dust is also known as Sevendust and majorly is used to kill insects. A broad-spectrum insecticide, as its name implies, lacks a specific target species. Most of the insects in your yard can be killed by it. Unfortunately, if bees get into touch with it, they will also be affected. You may use Sevin dust to keep vegetable crops secure. Additionally, it may be applied to safeguard flowers, and lawns, to prevent fleas and ticks.

Sevin dust is available in several distinct forms. It can be found in the forms of pellets, granules, powder, and liquid concentration. The majority of people prefer to use the Sevin dust that is granulated or pellet rather than powdered. As long as you do not touch it or ingest it, all forms of Sevin dust are safe.

The pellets,  dust, or grains of Sevin dust disintegrate when they get moist. Once the basic materials have disintegrated, the environment is once more deemed safe for people and animals.

Physical touch is how Sevin dust functions. Although most insects are immediately killed by it, it won’t stop insects from living in your garden.

Carbaryl is one of the major elements in Sevin dust. A neurotoxin known as Carbaryl affects the neurological system of insects. This helps prevent infestations and hastens population control. Sevin dust can, however, also affect helpful insects due to its contact-based toxicity.

Can You Use Sevin Dust On Houseplants?

Zeta-cypermethrin, the active component in Sevin dust kills more than 500 insect pests when it comes into contact with fruits, vegetables (including tomato plants), flowers, decorative plants, and ornaments. And it offers up to three months of protection for your tomato plants. Zeta-cypermethrin is known to be a non-systemic insecticide you may use on vegetables and fruits and is only present in Sevin spray pesticide in amounts of around 0.35 percent.

Sevin Dust is safe to use as a dust or spray on specified plants, such as flowers, roses, citrus fruits, trees, shrubs, and vegetables. Even more,  it doesn’t hurt plants or blooms on them.

It’s crucial to appropriately apply Sevin dust to your garden and lawn. Here are some tips to help you appropriately apply Sevin dust to your plant. Sevin dust has minimal toxicity for people and pets when used as recommended.

When an infestation initially shows signs, which can come with soil or developed over time, it is time to apply the Sevin dust to your plants. In order to avoid having to make multiple treatments later, when it could be too late to undo the harm, it is preferable to stop the pest and bugs from growing into a significant population in the very beginning. Here are some instructions which can tell you what to do and what to avoid:

  • Spread out as you move backward. By doing this, you can avoid inhaling the dust or breathing it after it has spread.
  • Put on a mask. This helps to further keep you from inhaling dust.
  • Put on gloves. Wear gloves and thoroughly wash your hands after using the easy-spread canister, even if you’re not contacting the dust directly.
  • Wait for the rain to come. Just Before it rains, sprinkle Sevin dust over the affected area. Wait for a couple of hours to reach where it needs to be before it starts to rain. The raw material will then dissolve, enhancing the effectiveness of the rain. It is secure for kids and animals once the vegetation and the ground has dried.
  • Read the guidelines. Read the labels, instructions, and other materials that come with Sevin dust. There are separate procedures and guidelines for each form of Sevin dust including granulated, liquid, and pelleted.
  • Avoid spraying or putting the Sevin dust on the flowers, especially make sure not to aim to where the pollinators land because it can kill them.  Leaving pollinating insects alive is crucial, therefore stay away from applying directly to flowers.
  • Take caution while handling veggies. Although it is okay to apply Sevin dust on plants, use caution. Avoid using it if harvest time is approaching. Before consuming veggies, make sure to give them a thorough wash.
