Over time any garden will pick up residents: snails, ladybugs, aphids, snakes and spiders. Our herb gardens are ringed with large rocks and these make a perfect home for Black Widow spiders. Lift a rock and you’re likely greeted by one waving one of its eight legs at you and thanking you for giving her such a nice place to drop an egg sac. The problem is, I don’t want them. I have a child that likes to play in the yard and I don’t want to worry about her being bit and I should have to tell her to stay away from places in the yard. Another problem is the herb garden is organic so poisons are a no-no there as they are anywhere else in our yard. I have read that cinnamon oil and eucalyptus oils work to repel the spiders but those aren’t working too well. So, does anyone have any experience in driving these garden residents away?
