Ladybugs appear when there are plants they find attractive and a food source like aphids.

Each spring, it’s exciting to see plants begin to sprout from the ground and new leaves unfurl. However, shortly after they emerge, I often notice aphids””an insect pest””showing up, eager to suck the life out of the newly emerging plants. In the past, as soon as I spotted them, I would grab some natural insecticide, like neem oil, hoping to rid my plants of the aphids. Unfortunately, this method didn’t always work. After researching, I found a fantastic book at the library called “Attracting Beneficial Bugs to Your Garden” by Jessica Walliser. This book taught me an important lesson about beneficial insects that eat aphids and how to create a healthy ecosystem in my yard to attract them. Two key lessons I took away from the book are:
1. Grow plants that attract beneficial bugs: Ladybugs and lacewings are voracious aphid eaters. They are attracted to plants such as fennel, yarrow, cosmos, dill, coriander, calendula, chives, and alyssum.
2. Let nature do its thing: Instead of intervening immediately to eliminate the aphids, I now wait a few days. Shortly after, I see the aphids, ladybugs, and their larvae arrive and begin devouring the pests.
When I let nature do its thing, the results are remarkable. In the photo below, you can see a plant covered in aphids. After waiting a few days, ladybugs arrived, laid eggs on the aphid-infested plant, and once the eggs hatched, the larvae feasted on the pesky aphids.
If you visit the Rust Belt Natives plant pop-up sale in my garden this month, you may have the chance to see this ecosystem in action. The sale will take place on June 14 from 10 a.m. to 1 p.m. and on July 12, Aug. 9, Sept. 13, and Oct. 11, all at the corner of N. Pacific Avenue and Gem Way. I hope to see you there, and happy springtime gardening!
