Ladybugs in the Garden

Did you know, our kids' favourite insect to catch in the yard, are a tiny garden warrior? If you’ve ever spotted a ladybug crawling across your plants, count yourself lucky—these tiny beetles are among the best allies a gardener can have in southern Saskatchewan.

Why Ladybugs Are a Gardener’s Best Friend

Ladybugs (also called lady beetles) are natural predators of some of the most common garden pests, especially aphids. A single adult ladybug can eat up to 50 aphids a day, and their larvae are even hungrier—devouring hundreds over their lifespan. In addition to aphids, they also feed on scale insects, mites, and mealybugs.

For gardeners this is especially helpful. Aphids can be a major nuisance on everything from roses and delphiniums to tomatoes and fruit trees. 

Native Ladybug Species in Saskatchewan

Southern Saskatchewan is home to several native species of ladybugs, including the Convergent Lady Beetle (Hippodamia convergens) and the Two-Spotted Lady Beetle (Adalia bipunctata). However, in recent years, gardeners may also encounter the Asian Lady Beetle (Harmonia axyridis), which was introduced as a biological control and has since become widespread.

How to Attract Ladybugs to Your Garden

To encourage ladybugs to make your yard their home, try the following:

• Avoid chemical pesticides. These kill both the pests and the beneficial insects that feed on them.
• Grow pollen-rich flowers. Ladybugs also enjoy nectar and pollen. Try planting yarrow, dill, marigolds, calendula, sweet alyssum, or tansy.
• Provide shelter. Leave small patches of grass, mulch, or even a log pile where ladybugs can overwinter or hide during hot days.
• Water lightly. Shallow dishes or dew on leaves give them drinking water.

A Symbol of Good Luck—and Good Gardening

Ladybugs aren’t just charming—they’re essential players in a balanced garden ecosystem. For gardeners, they offer a free and effective line of defense against destructive insects. If you spot one, take it as a sign: your garden is healthy, welcoming, and doing something right.
