Using Eggshells as Organic Pest Control

By | 154 Comments

Using eggshells as organic pest control is inexpensive, and easy! In this post, not only will I show you how to use eggshells in your garden, I will also show you exactly how to prepare eggshells for garden use – including tips for cleaning and drying eggshells, grinding them into powder, and storing eggshells and powder for later use.

Using Eggshells As Organic Pest Control

The flea beetles have been worse than ever in my garden this summer, and the Japanese beetles are no fun either. On top of that, the slugs have been turning my hostas into Swiss cheese (Ahhh, the joys of gardening). I need all the help I can get fighting these and other bugs in the garden organically.

Using Eggshells As Organic Pest Control

There is a well known organic pesticide called diatomaceous earth, which is basically the fossilized remains of creatures that are ground into a fine powder.

This works as a pesticide because it gets under the shells of beetles and acts like bits of glass to cut them up and kill them. Snails and slugs will also die if they slink across it.

Well guess what, ground eggshells can work the same way. I eat a lot of eggs, so I have plenty of eggshells. Which means I can have the benefits of diatomaceous earth for free – Oh, and I’m all about free pest control!

How To Make Eggshell Powder For Your Garden

There are lots of uses for eggshells in the garden. So, whether you want to try using eggshells as organic pest control, or you plan to use it in other ways, the steps for making organic eggshell powder are the same.

Below I will show you how to prepare eggshells for garden use, and give you details of each of the steps. The steps include cleaning and drying eggshells, grinding them into powder, how to use your eggshells as organic pest control, and how to store leftover eggshells or eggshell powder for later use in the garden.

How To Clean Eggshells

I get asked about the steps I use for cleaning eggshells before crushing them all the time. But the truth is, I don’t really fuss too much about this. If there is yolk or a lot of egg whites left in the shells, I will give them a quick rinse with water before drying them.

But if they’re already fairly clean, I don’t bother taking the time to clean them. I’ve never had a problem with my eggshell powder stinking. So, my advice on this would be… if your eggshells are dirty, then definitely rinse them with water before drying and crushing them.

Methods Of Drying Eggshells

You’ll definitely need to allow the eggshells to dry out before crushing them, so don’t skip this step. There are a few methods you could use for drying eggshells. Just as with cleaning the eggshells, my method for drying them isn’t fancy here either. I simply lay them out on a paper towel and leave them sitting on the counter for a few days.

If I have a lot of eggshells to dry and I don’t want to clutter up my counters, then I toss them into a paper bag in the pantry where they dry out in a few days. If you choose to toss them into a paper bag like I do, just make sure you don’t stack the eggshells. Toss each one in there loosely, otherwise they won’t dry as fast, and they might even start to mold or stink (I’ve never had this problem with mine, but some people have).

I’ve also heard of people putting their eggshells into the oven on low and drying them that way. But I’ve never tried this method, so I can’t speak to it.

How To Grind Eggshells Into Powder

Once the eggshells are completely dry they will be very brittle and break easily so you know they’re ready to be ground into powder. To grind eggshells into a powder, you can use a mini food chopper or a coffee grinder.

You’ll probably need to crush the eggshells up a bit before grinding them so you can fit more into the grinder at once. I simply crush mine up in the paper bag or the paper towel quick before putting them into the grinder.

In my experience, the best grinder for eggshells is a coffee grinder. The coffee grinder does a great job of grinding the eggshells into a powder. When I used my mini food chopper, I found that the shell pieces were larger than the ones I crushed in the coffee grinder.

The food chopper still grinds the eggshells, but the result isn’t as fine of a powder as you get with the coffee grinder. So, if all you have is a mini food chopper, then you can try using that. Otherwise, I recommend getting yourself an inexpensive coffee grinder to use as your eggshell grinder.

How To Use Eggshells In The Garden

After the eggshells are ground into powder, you can take them out to the garden and use them right away. To use eggshells as organic pest control, sprinkle the eggshell powder directly onto the pest insect.

Here I’m using it on Japanese beetles. They really don’t like it, and will start to squirm and move around. It won’t kill them right away, and sometimes they will fly away, but they’ll die in time.

Be careful though, eggshells will kill any type of garden beetle – even beneficial ones. It’s best to sprinkle the eggshell powder directly on the specific pests you are trying to control. I do not recommend sprinkling it all over your garden, or you could end up killing the good garden bugs by accident.

To use crushed eggshells for slugs, snails and flea beetle control, sprinkle the eggshell powder around the base of the plant. Eggshell powder sprinkled around plants will need to be reapplied after a heavy rain.

Just be careful if you’re wearing dark pants, and don’t wipe your hands on your pants as you are spreading the eggshell powder (oops!). It can be a messy job.

Better yet, avoid the mess of spreading eggshell or diatomaceous earth powder by using a pest mini duster – awesome!

How To Store Eggshells For Garden Use

As long as they stay dry, you can store eggshells or eggshell powder for later use in the garden. Simply store your unused eggshell powder in a dry location.

I keep mine on a shelf in my garage, it doesn’t matter if it freezes in the winter. You could also keep them in a pantry or even the fridge or freezer if you would rather.

There are many uses for eggshells in the garden. They’re great for the health of your garden, and they add calcium to the soil. Simply toss them into the compost bin, or add the powder directly to your garden beds. Be sure to try using eggshells as organic pest control in your garden too, and see if it works for you! Don’t worry, if you don’t have access to eggshells, you can buy diatomaceous earth for pretty cheap too.

      • Could I use egg shells to control spiders?
        I live by Lake Erie and I’m innendated with them. I don’t like using pesticides to control the problem.

        • I would not recommend using eggshells for any type of broad application, because they can kill other beneficial bugs too. You could try sprinkling the eggshell powder directly on the spiders, but it sounds like that would be a lot of work given the amount of spiders you have.

        • Hi Kathy, I just saw a post that if you make a mint solution and spray it around the outside of your house and it’s safe to spray inside your house as well, that it repells spiders, crickets and ants. I haven’t tried it yet, but plan on doing so.
          How to: It didn’t really say, but I think you would get some mint leaves and make a slurry with water. You’d have to get the leave really tiny in order to use a spray bottle.
          It’s a thought….and mint smells good!

    • Awesome! I always used to put the eggshells into my compost bin too, but they really stick around a long time. Then I started crushing the eggshells I put into the compost bin. Now I just use them as pest control and add the eggshell powder to the soil of my raised beds directly rather than put them whole into the compost bin. I feel like they are more beneficial this way.

  4. I'm definitely going to try this! I always just toss egg shells in the compost and they are so slow to break down. I did effective rid my apple tree of Japanese Beetles with a homemade pepper spray, but that stuff was potent!

    • Yes, eggshells are very slow to break down when they're whole. Good for you for being diligent enough to rid your apple tree of those pesky beetles using pepper spray. Wow, you must have had to wear a mask for that job. I've touched my eyes after cutting up peppers, and it is very painful!

  7. How long can you keep this stored? I am just starting to build raised garden beds for the spring. We can't plant anything right now with the snow and cold (we live in CO). If I keep these in an airtight container, can I start stocking up now?

    • Eggshells don't have an expiration date. I save mine though the winter and use them throughout the summer. Just make sure they are completely dry before putting them in a sealed container or they could get moldy.

    • As far as I understand, it only harms bugs with a hard outer shell, like Japanese beetles. But, it’s best to only use it directly on the pest insect rather than just sprinkling it everywhere.

      • Sweet. This will kill the ticks here in Northern, About, Canada. Hopefully I can get a lot fast…want to spread my yard with them….Would it be okay for people to walk on them or would that run the whole process and be a waste of time? Lots of people saying their kids are biten this year

        Reply

        • I wouldn’t recommend spreading them around your whole yard. The eggshells can kill beneficial insect in your yard too. Also, the eggshells would be washed away or pushed down into the soil after a heavy rain, so they don’t have a very long lasting effect. Sorry to hear about your tick problems. Keep your grass mowed low to help prevent ticks in your yard.

  10. Hello. This looks great. Thanks for the tip. One quick question. How about ladybugs? I don't want to harm them… Need them for my basil! So should I just avoid using on my basil?

  12. I especially want to know if you have any idea if this would get rid of bedbugs?
    Or how about along the baseboards for roach control?

    And maybe you do or don’t know about this:
    What about on the floors, baseboards or porch for flea or tick control?
    Could it be directly applied directly to the fur of pets? Seems like the calcium would be good for dogs and cats, but I haven’t a clue how it would affect their digestive tract.

    Thanks!

      • Trusted websites promoting a natural raw diet for dogs recommend using ground egg shells mixed with the dogs food to obtain the correct amount of phosphorus. Dogs require a high ratio of phosphorus to calcium ratio.

    • I used to do that, but now I just toss them into a paper bag (not plastic). That way, I can just leave the bag in the pantry, and don’t have eggshells drying on the counter all the time. As long as they’re not stacked together, they will dry quickly. If they’re stacked or crushed while they’re wet, they could mold.

  14. I have been using broken up eggshells in my garden for years now. I don’t have the beetles, just slugs and earwigs, so I don’t need to ground them up. The eggshells work wonderfully. I haven’t had a bug problem since I started using the shells.

    Reply

    • I have a major problem with earwigs in my mulch. I’ve tried wet newspaper to no avail. Sherry and/or Amy, how should I use eggshells? Whole or crushed? Should I put them on top of the mulch or underneath? The earwigs are mostly living and multiplying in the mulch under my apple trees.SO many and SO gross!! Will the eggshells harm the trees? Are the earwigs harming anything or just giving me a bad case of the heeby-geebies? :/

      Reply

      • Yuck, sounds nasty! Earwigs can be both beneficial and pest insects. They are beneficial in orchards, as they eat aphids and other small insects. You can sprinkle the eggshells right over the top of the mulch where you see the earwigs. Also, try to allow your mulch to dry out a bit if you can, and only water that area in the morning. Earwigs love it moist and they feed at night. So watering at night will only help them thrive. And no, the eggshells won’t harm your trees, they are actually really good for the soil. Here’s a really great post that I found about how to control earwigs… How To Control Earwigs

  21. I have been using crushed egg shells for a couple of years now but I have been removing the inner film first. I was told to do that. Do you do that or even think it is nessessary? I also just crushed them using a mortor. Do you find grinding them better?

    Reply

    • I don’t remove the inner film (I don’t even rinse them out). I don’t think it’s necessary, and it sounds like a lot of extra work. I’ve never tried crushing eggshells with a mortar, so I’m not sure how fine they get. I like the coffee grinder the best because it grinds the eggshells into a powder. Also, it seems like less work than manually crushing them.

      Reply

      • I’ve used a mortar and pestle for grinding egg shells on the farm. Works well. As mentioned, more labor than a grinder. But it isn’t hard work and I find it is a relaxing moment, almost meditative. Worms in the garden benefit from the egg shells for reproduction, I find grinding them first speeds up the usability.

  26. I have been using eggshells for so much anyway, but I had no idea you can do this much stuff with them. I just read another post about how you can use the skin as a band aid, use the shells for planter (to keep as a decorative piece, or use a planter) cups you don’t have to remove before planting either – the whole thing gets planted. You can use them for decorative pieces, too. I my self mix them in to every potter I set up for healthy soil; it does so much for the soil and plant alike. You can even use them for Easter decorations and Christmas ornaments! Eggs are the by far the most repurpose-able item in our kitchens; yet so many get thrown out in to the garbage. I am glad more people are starting to use them for other things. They are little miracles! Enjoy your eggs everyone! <3

  35. I’ve been using egg shells in the garden for the past two years. I keep an empty #10 can in the warming oven of my wood cookstove and throw all my eggshells into the can as I use them. They dry quickly in the warming oven, then I grind them to a powder in the blender. I put a Tbsp of the powder at the base of tomato, eggplant, and pepper plants and water it in. It’s amazing! The plants grow big and tall and I’ve not had any problem with blossom-end rot since I started this. I haven’t tried the powder on pests, though, but I certainly will this year! Thanks for the information.

  36. I have been using ground fine eggshells to feed back to my chickens for 3 years now. Not only does it strengthen the eggshells, but it stops the hens from eating the eggs. Also I have noticed that when a hen has chicks, they encourage the chicks to eat the powdered shells. I am so happy to learn that I can use them as an insecticide. And that it stops blossom end rot on tomatoes and peppers. I am planning to do as advised for them this year and also to do it for my melons. I have a hard time getting my melons to reach maturity due to blossom end rot. fingers crossed! m

    • Oh wow, that is very interesting about the chickens! Eggshells are beneficial in so many ways! I hope the added calcium will help with your melons too. Also, make sure to water the melon plants consistently. Inconsistent watering is another factor in blossom end rot. Good luck!

I had heard eggshells could be ground up to repel insects, so today I ground them fine in a coffee grinder, and I powdered it on those nasty ants & aphids. The ants went into a tizzy! Thanks for the great information. I’m going to put it at the base of my tomato and zucchini plants, too.

    • Great! It’s not the ants that are destroying the flowers, it’s the aphids. Ants are known to bring aphids to plants so that they can feed off the sweet dew that’s created as a bi-product of the aphids feeding on plants. The eggshells won’t harm the aphids, unfortunately. But soapy water works great. Here’s more information about getting rid of aphids… How To Get Rid Of Aphids On Plants

  45. I have been adding crushed up egg shells to my raised bed vegetable garden for years. This year I got six chickens and have been crushing the shells with a mortar and pestle and putting the tiny pieces into the vegetables I now feed for added treats instead of putting them into my compost pile. After I crack an egg for people consumption I place the shells on my kitchen counter for three days and then put them into a quart sized canning jar. As the jar fills I smash the egg shells down with a knife or the handle of a hammer and I continue adding more shells until the jar is full of coarsley ground shells. When the quart jar gets full of crushed egg shells, I take my mortar and pestle and crush them finer, but not to a powder. I put these finer ground shells into a clean parmesan container with holes in the lid. I always have ground up shells available for the garden and for adding to the feed of the chickens. When I have used all the DE that I bought for mite and flea control for the chickens I will try the egg shells instead. But, will I have enough egg shells for all of the new and old uses? Thanks for all of your gardening tips.

    • Great! I have tried using a product called squirrel stopper with some success. It keeps them off the bird feeders, but you have to keep reapplying. Knock on wood, but I’ve only had problems with them digging in my dirt, so I haven’t had to worry about them in the garden yet. If they’re bugging a specific plant of yours, you could surround it with chicken wire. Not pretty, but that’s what I do to keep the rabbits from destroying some of my plants.

  48. Amy, after I saw this tip last year to use powdered egg shells to combat Japanese Beetles, I saved every single egg shell from ever single egg my family ate. I rinse them out briefly so they dry faster, place them on a paper towel, and slide the paper towel over the glass cook top burner (still warm but not hot enough to burn the paper towel) I just used to cook the eggs. They dry in a few minutes and then get tossed into a recycled ice cream plastic tub. a few minutes in the oven would work as well, but set a timer! Burned egg shells woud ruin the house! When the tub is full I put the shells into the food processor to grind them to a powder. I used to use a small electric coffee grinder, but it only ground up a few shells at a time. The food processor can handle much, much more. I store them in ziplock bags, ready to dust the garden.

    I have several pounds of ground egg shells for my annual effort. So far this year I have used them on my tomato and potato plants (these were destroyed last year, but are strong and healthy this year). This evening I wet down my small apple trees and dusted them as well. The Japanese Beetles LOVE apple tree leaves! Wetting down the plants helps the shell dust to stick to the plant. Light rain does not seem to remove the egg shell dust, but heavy rain certainly does. The egg shells keep the slugs away from my potato plants as well.

    Another resource for egg shells might be your local diner or breakfast place. My local eatery said they just throw them out, but if I pick them up at the end of the day, they will save them for me. They go through dozens of eggs a day. I could probably double my annual effort in just a week or two. I’m going to try this out this coming week. I’m going to drop off some sealed containers to make their job easier.

    • I don’t know the answer to that, sorry. I know there are some people who bake or microwave the eggshells before grinding them, so you could do that if you’re concerned. Or you could boil them to get them hot enough to kill any salmonella.

  51. Amy, I am so glad that I came across your website! I love gardening and have been doing so for almost three years. (Yep, I’m still new at this). I find that I want to plant many different varieties of vegetables and so far so good. I am learning rather quickly what to plant, spacing, getting more than one harvest from some vegetables. I’m having fun and I truly enjoy growing my own!!! I am so glad that I ordered your ebook on controlling pesky bugs (grrr I hate them!) I have bookmarked your web page as a reference and I thank you for helping all of us that want to grow a healthy and abundant garden year after year with fresh produce. They taste so good! I’ve even dehydrated vegetables and herbs and took up canning as well to preserve and use at a later date. My family loves it!

    When I read about using the eggshells I almost fell over in my chair! Why? Because I started using eggshells as a deterrent to control slugs, but I never thought that they could control other garden pests (Japanese Beetles….boy did they have a field day with some of my plants) I was so mad. The one thing I didn’t do is make the egg shells into a fine powder. Also, do I just let the egg shells just dry out? I’ve been letting them dry out on a low temp in my oven. Maybe I should stop doing that. I save ALL my egg shells and crush them up, put them in empty plastic coffee cans and wait until it’s time for my garden. I thank you so much! I will continue to read, learn, take notes from you, including “building” my own trellis…I am interested in vertical gardening for more space so my plants can breathe…..you’re awesome! THANK YOU AGAIN!!!!

I just leave mine sitting on the counter or toss them into a paper bag for a few days to dry them. But either way works fine. So excited to hear you’re getting into vertical gardening! Keep your eyes peeled, because I have a TON of information planned next year all about vertical gardening, starting in late winter/early spring. It’s going to be EPIC! 😉

  58. Hi , I have been using egg shells for my outdoor plants. They really work good. I recently got couple of indoor plants and getting gnats around them. Can I sprinkle egg shell powder on my indoor plants ?

  59. Thanks for the info on eggshells, but does it works on ants too? Never noticed if they have hard shells or not. I’m also going to use it in my soil for plants and tomatoes.
