What Insects Does Sevin Dust Kill (UPD 2020)

What Insects Does Sevin Dust Kill?

Insects that Sevin dust kills include potato beetles, parasitic wasps, ladybugs, bees, roaches and fleas. Sevin dust contains a chemical called carbaryl, which kills over 100 types of insects.

Sevin dust works by degrading an insect’s nervous system through ingestion or direct contact. There are different variations of Sevin dust, including 5-percent carbaryl dust, 10-percent carbaryl dust and garden dust. Sevin-5 is reserved for outdoor use on garden lawns, and it kills 65 different pests, including Japanese beetles, grubs and ticks.

Sevin dust can be applied in powder form or mixed with water for spraying on crops, such as tomato plants. Sevin dust is normally applied on fruits and vegetables, but the crops must be washed with water before these foods are consumed. However, there are times when spraying around the plant is necessary. For instance, 2 tablespoons of 50-percent Sevin powder with 1 gallon of water is for application on weed-infested areas around tomato plants, which are havens in which stink bugs thrive. The solution should not be sprayed directly on the tomato plants, and Sevin dust must never be applied on flowering plants to avoid killing honeybees.

The liquid form of Sevin dust kills insects like Colorado potato beetles. Liquid Sevin dust works best on plants that reach up to waist or chest level. Adding water to liquid Sevin dust is still necessary for thorough application of an area.

Safety of Sevin Dust

I need to know if this pesticide Sevin Dust is a safe product to use in garden for pests and whether or not it is poisonous. I was reading about this stuff on a website foodtruthfreedom.wordpress.com and read that it is poison not just for insects but humans as well. They claim the Sevin dust is consumed via the leaf of the plant, the produce of the plant and that it gets in the water system after rain and or watering the garden. I been using this stuff for years due to my father using it when i was a kid. I hope it hadn’t affected my health in any way.

If Sevin Dust is bad for humans, why would they allow the stores to sell it? I learn that the technical name for it is Carbaryl and that it was first manufactured during the 50s by some plant which sold out. I noticed that it seemed to have damaged my tomato and squash plants as well for some reason or another. Don’t know whether to blame the Sevin dust, drought or too much rain lately. My squash plants are just rolling over and dying for some reason. I have always put Sevin dust on them in the past, especially at the bottom of plant where the squash bugs are at. I haven’t seen any squash bugs by the way, not yet. The tomato plants seems to be dying as well. I guess I will wash the dust off of them. I didn’t put that much on them, just sprinkled it as always.

i hope you can provide me with good information on this Sevin Dust. i think I will stop using pesticides in the future. I also read on the internet that self-rising flour is good for fighting pests. So is garlic/red pepper spray. Guess I will try and see. Thanks, hope to hear from you soon.


How to Use Sevin Dust on Tomato Plants

Sevin dust is one of the brand names of an insecticide labeled for use on tomatoes and other crops, and also for dusting the coats of farm animals afflicted with pests. The active chemical in it is carbaryl. It kills tomato armyworms, fruitworms, hornworms and stinkbugs, as well as bugs that attack other vegetables. This is a toxic powder; wear a mask, gloves and goggles when handling it.

Step 1

Select a Sevin dust formula that comes in a shaker can ready for use in the home garden.

Step 2

Check the weather outside for windy conditions. Postpone Sevin dust application whenever you expect a breezy day.

Step 3

Dust your tomato plants prior to harvest as needed. Coat both the top and bottom of all leaves with a thin layer of Sevin dust. One manufacturer recommends following the rate of ½ lb. of dust per 1,000 square feet of tomato plants as a guideline for how much is safe to use.


Stop using Sevin dust no later than three days before you harvest the tomatoes.


What Can I Put on the Turnip Greens in My Garden to Keep the Bugs Off?

Tender turnip greens are for some a well-kept garden secret. While chard and kale are popular greens in the garden, some people are devoted to other greens such as mustard, beet or turnips. Healthy greens are not only delicious on the dinner table, they’re important to the health of the whole plant. Turnips are prey to a number of pests and require careful attention to keep them free of insects. It is worth protecting turnip greens — they are high in vitamins E and C, have usable calcium, folate and a full range of amino acids.

Common Pests

Turnips and other greens are especially bothered by several insect pests. Aphids are a number one culprit. They suck the sap from the plant. Cabbage loopers love turnip greens just as you do. Flea beetles can be a major problem. Take the time to learn what these turnip pests look like and how to spot the adults and larvae. This will give you an idea where to target your approach to getting rid of them.

Garden Health

Prevention is always the fist line of defense when it comes to any garden pests. Keep weeds away from your plants to reduce habitat for insects. Insects are interdependent, so if one type is encouraged by weeds or other foods they may like, the ones who prefer leafy greens may move in too. Keep the ground free of dead and dying plants and rotted vegetables to reduce their food. Keep your turnips well nourished with rich compost because healthy plants have more resistance to pests.

Beneficial Insects

Introducing beneficial insects to the turnip bed can reduce the population of harmful insects. Examples of these are ladybugs, green lacewings and beneficial nematodes. You can purchase them at some garden centers or through an online distributor. These are predator and parasitic insects that can help you battle the undesirable bugs on your turnip greens. Make your garden attractive to them by providing other foods they like such as flowers for nectar.

Synthetic Pesticides

The synthetic pesticides for turnips include spinosad, whose makers claim it has low environmental impact, long residual effect and is no harmful to beneficial insects. For aphids or whiteflies use pymetrozine. It is a direct spray specifically for this type of bug and can kill them quickly.

Natural Insecticides

Turnips can be benefited by an interplanting of some other plants. These discourage insects that target turnips. They include mint, onions and garlic or herbs like anise, chives and coriander. You can also combine household products to create a useful natural pesticide. A homemade horticultural oil can be made from soybean oil mixed with liquid dish-washing soap to suffocate the bugs. Some people simply spray them off with a hose. But if you do this, make sure to also remove them from the ground beneath the plant. Purchase diatomaceous earth at a garden center to dust on plants to deter aphids.

    Keep in mind this is NOT an organic solution like Neem oil, but Sevin 5 dust is very effective on a broad spectrum of garden pests. It WILL KILL honey bees and other good pollinators, so DO NOT use when plant is flowering or near the flowers of the plant! No use in saving the plant if you can’t get live pollinators in there so to help produce fruit. For application please use gloves and wash your hands and clothes. Using fine cheese cloth or pantyhose over the container will create a finer powder, but you should probably wear a mask to apply so you don’t inhale. Also, for many veggies, you should limit use to 3 times in one season. Over use is not only bad for environment but can end up in your food supply. Take care.

    Try dish soap mixed with water and a few drops of peppermint oil or any pungent essential oil………..I have been doing this for 35 years, I wouldnt put Sevin near anything I was going to eat. You can google dish soap for insecticide and read about it and get ideas and mix ratios………definitely stops leaf eaters

  • Brittney Pearson says:

    Do not listen to those whom recommend dish soap mixed products as they will harm your plants. Seven is safer as long as you don’t apply in right on the food you will harvest, and don’t reapply any at all a week before harvest xoxo. And do not allow pets near seven until the dust settles.
    But just Incase you get some on your food that will be harvest, just wash it well before consumption xoxo, just be fair warned.. seven kills basically ALL bugs. Which sadly, includes some kinds of bees.

  • Gabe Val says:

    Cutworms, they work at night BT is a better solution to a organic garden. Another way is to lightly dig with your finger around our devoured plants and I will find them. They will wake up at night and move to the next plant. Good luck

  • snoop furlow says:

    Yes it works!because i had blowed in a wall void using ,4 cans.. it took out over 5000 stinging wrasps,their larva in a wall void!its deadly. is very toxic to honey bees, as well..i wouldnt apply it inside a home.,i did a test,its not easy to wash away.i also treated a bumble bee hole as well 9 months ago,on dry surface,sevin dust was still in the hole..iam buying some more of that stuff!
