eggs four-2031

Via Facebook, I discovered a Minneapolis blogger by the name of Amy Andrychowicz who had an eggs-cellent idea for using eggshells as organic pest control. Basically, she suggests grinding them up and applying them to your vegetables at ground level and on the leaves to control all manner of bugs and beetles we don’t want on our veggies. I encourage you to visit her blog to get the full scoop on it. This post was #3 on her blog’s Top Ten list for 2013 and you know the idea was good if it continues to be passed around on Facebook.


  1. Grits (the kind you eat, not the girls raised in) is good to pour around veggies to keep caterpillars away. They fill up on the grits and die. This was taught to me by an old gardening aunt. It is NOT Master Gardener knowledge. I have heard of using egg shells as well.

    1. Becky B – I had previously heard of eggshells, too, but not grinding them up like that. That seemed genius to me because you could then sprinkle them on tomato leaves for caterpillars. GRITS, though! I’m not sure I’ve heard about grits. I’ll have to try that around my squash. The only decent squash crop I’ve had was the year I took a seed planting class at McDuff and they gave us some Zephyr F1 squash seeds. It’s a yellow squash with a green bottom. Excellent flavor, blah blah blah but the seeds seem to be available ONLY through Johnny’s Seeds who is too expensive for my meager budget. I am waiting until they are released to the general market. The Juliet plum-like tomatoes were also given to me in that class and their seeds were finally released this year (2014). I have patience…

  2. Cinnamon powder will do wonders for dealing with ants. Great for keeping them out of the house or out of sections of your garden. The grits trick I’ve heard of, but not used. Eggshells can be good for certain specific pests, but I don’t think I’d want to put them on the leaves. They’ll also add calcium to the soil – but don’t use them for blossom end rot – just use less nitrogen fertilizer and that will usually take care of itself. I’ve been experimenting with using them (ground up) to tie up the sulfur in my soil in an attempt to make my onions sweeter. The jury is still out on that one.
