At first glance, those little white butterflies fluttering around your vegetable patch might seem like a welcome sign of spring. Unfortunately, if they're hovering around your cabbages, broccoli, kale or cauliflower, they're probably not butterflies at all in the harmless sense — they're commonly known as cabbage moths (or cabbage white butterflies), and they can spell trouble for your garden.
While the adults don't actually chew on your plants, they're experts at finding leafy greens where they can lay their eggs. That's when the real problem begins. Before long, those tiny eggs hatch into ravenous green caterpillars that seem to have only one mission — devour every tender leaf they can find. A healthy crop can quickly end up looking like lace, with ragged holes, damaged hearts and disappointing harvests.
In a video, gardening expert Nicole Johnsey Burke (@thegardenaryco) explains just how quickly cabbage moths can become a major headache. A single female can lay hundreds of eggs over her lifetime, meaning what starts as one or two innocent-looking visitors can soon become an army of hungry caterpillars munching their way through your vegetable patch. Catching the problem early is the key to keeping your crops healthy.
How to Keep White Butterflies Away From Your Garden Naturally
The good news is you don't have to reach for harsh chemicals to fight back. One of the easiest natural deterrents is companion planting. Strongly scented herbs such as rosemary, thyme, sage, mint and oregano can help confuse cabbage moths as they search for their favorite plants. Flowers like marigolds, nasturtiums and calendula not only brighten the garden but can also help attract beneficial insects that prey on common pests.
Many gardeners also swear by planting dill, fennel or parsley nearby. These herbs attract tiny parasitic wasps and other helpful insects that naturally keep caterpillar populations in check. Adding biodiversity to your garden creates a healthier ecosystem where pests are less likely to take over.

Physical barriers work wonders too. Fine insect netting or floating row covers can stop cabbage moths from reaching your crops in the first place while still allowing sunlight and rain to reach your plants. Regularly checking the undersides of leaves for small yellow eggs and removing them by hand can also prevent an infestation before it starts.
The next time you spot those cheerful white visitors fluttering through your garden, don't panic — but don't ignore them either. With a little vigilance, clever companion planting and a few natural defenses, you can keep cabbage moths from turning your prized vegetables into an all-you-can-eat buffet.
