Controlling Cabbage WormsControlling Cabbage Worms

If you have tried growing cabbage before you will know that these little green guys can turn a perfectly good cabbage plant into a piece of green Swiss cheese!

Well I was fed up with losing all my cabbage to these damned green worms so I found an article about Controlling Cabbage Worms.

Turns out it is really simple to Controlling Cabbage Worms.

All you need is some baking soda and some flour.

So what you will do is take some baking soda and some flour in equal parts.

So in a bowl mix 1 cup of flour with 1 cup of baking soda.

Make sure to mix it well.

Take the mixture and dust your cabbage plants with it.

The cabbage worms will still come and eat your cabbage leaves, but within a day or two the mixture of baking soda and flour will kill the cabbage worms!

Make sure to repeat this as often as you need to.

Like most things with gardening there is no permanent solutions, just band aids.

This is a very effective, natural and non-intrusive way of Controlling Cabbage Worms.

    I found that using a “Jelly Bag” and “pouncing” the jelly bag over my garden plants helps in dusting. I also do this using Diatomaceous Earth.

    1. Joy says:

      Good idea!

      1. Jana says:

        Jelly bag?

        1. Laura says:

          Right I’m wondering too! Details plz!

    I.covered my cabbage last year and wound up trapping them cabbage worms inside. They had a heyday,.I picked them off but couldn’t began to stay ahead them.

      I no longer have a problem with the cabbage white caterpillars. For the last 6 years I cover my entire cabbage, broccoli, kale and kohlrabi bed (4×8 feet) with a mosquito net for cots right after I plant them. You can get them at sporting goods suppliers online for about $14 to $16. I put 7ft cane pole at the corner of my bed and short pieces acoss each pair of end poles at the top to make a frame to support the net. The nets come with either fabric loops or metal rings in the four corners which I attach to the corner poles. The edges are then held down with rocks to keep it from blowing around. These last me about 4 years if i don’t let the broccoli go to flowers late in the summer. If I do then bees around here come and cut big holes in my netting to get to the flowers. I usually remove the netting after harvesting all but the last of the broccoli which I then let go to flowers for the cabbage white caterpillars which turn into those cute little white butterflyies.

    Now, any answers to getting rid of the squash borers!!!!!

    1. Sheri says:

      SQUASH VINE BORERS: Melittia cucurbitae: The clear winged wasp-like moths lay single eggs, often bnear the base of stalks. The caterpillars hatch, then bore into the stalk or leaf stems. They tunnel along, feeding on inner tissues, growing into fat, one inch long borers with wrinkled skin, The boreres push brown refuse out of thier entrance holes. These borers attack squash, pumpkins cucumbers and others. LIFE CYCLE: Two generations may occur before wintering over as pupae. 1. Eggs laid in the soil. 2. Larva or caterpillar stage, white with dark head. 3. Pupate in soil after about a month as a caterpillar. 4. Adult moth. CONTROLS: Biological: Release trichogramma to attack borer eggs. Use Nc nematode as a mulch around vines. CULTURAL: Inter-plant garlic and onion. Use fall plowing (turn and break up soil) to destroy pupa. (In early spring I turn, break-up and treat with Diatomaceous Earth and at this time I can see and kill them in the soil, just make sure you have eye protection when you squeeze the life out of them!)Use pheromone traps to monitor for adult moths. ACUTE: Try injecting Nc nematodes into the borehole with a medicine dropper. Slit stem to remove borers and pack dirt over the slit. Use weekly spraying of Bt when first vine runners appear.

        very cool info thanks a lot

        I use small, plastic Dixie cups. I spray then the same colour yellow as squash flowers, and I put dish liquid in them about a third of the way. They try to feed on the “flowers,” but get trapped and die, instead.

  4. Ted Thompson says:

    The gal that covered her cabbage needs to use something like cheese cloth. You should try to do this shotly after planting, use somthing t hold it off the plants. It is the little white butterflies that leave the worms. As soon as you see them it is hard to stop, unless you treat the plants then recover them. I’ve used diatamatues earth before also.

    1. Martin says:

      I have white cloth how do I treat the cadage with bakeing soda

  5. Gail says:

    Cabbage ‘worms’ are actually catepillars that eventually turn into cabbage white butterflies!

  6. Gwynn says:

    In one place you say baking soda and in another you say baking powder. Which one should I use?

    1. MrCompEng says:

      Thank you for correcting that! You want to use baking powder!

      1. Penny says:

        I just re-read the recipe and it says “baking soda” throughout?

        1. MrCompEng says:

          This has been a bit of a screw up lol. Baking soda is what I corrected them all to. I am so sorry for the misinformation!

          1. Lee says:

            Sorry i got confused! should we use baking soda or baking powder?

          2. Dianna says:

            Baking Soda, the post has been updated 🙂

    Diatomaceous Earth is not a safe substance. It’s known as an agent to cause cancer especially in the lung. It is from the earth it’s not a chemical but it’s used in pool filters and the pool industry warns of the dust. Use a dust mask around it. It’s no joke. It’s kills insects by cutting their skin asDE is fossil remains of tiny marine creatures. To the insects it’s like broken glass.

    1. S. ali says:

      Hi chuck I use Diatomaceous Earth in my chicken coop and in their dust bath.
      It’s basically to keep them from mites.

  8. Cricket says:

    Do you have a remedy to getting rid of fleas in the house??

    1. torben says:

      i put diatomaceous earth all over a heavily invested rug. when walking over the rug my ankles would get covered in fleas. it killed all of them really quickly.

  9. barbara says:

    what is the difference between baking soda and powder?

  10. Traci Merrix says:

    We dust our cabbage, greens, green beans with self rising floor, about once a week…it has baking soda and powder in it when the pesky critters ingest the flour they bust, die

  11. Beverly Bates says:

    I mixed half flour and half baking soda. My cabbage died.

  12. Amy says:

    Yes I used the baking soda and flour mixture and dusted mine with it and over night the plants have yellow wilted areas on the leaves and they have started to die. You might not want to use this recipe or it needs to read baking powder if that’s the correct ingredient

  13. Jacky says:

    Will this work on brussel sprouts?

  14. Stacey Hamilton says:

    I used half flour and half baking soda and it white blotches all over my kale.

  15. S. ali says:

    I use diatomaceous Earth in my chicken coop and in their dust bath.
    It’s used to kill the mites on the chicken and in the coop.
    So far it has been working coz I’ve had chicken for over a year and thankfully my chickens are mite free☺️

  16. Tiarnie says:

    Ok so I’m a bit sceptical about using this method. Can anyone tell me what actually works please???
    Desperatly looking for a natural way to get reed of these little buggers
