How Insect Activity Changes in Your Garden During Winter.
As the cold sets in and your garden slows down, so too does the bustling activity of insects. But contrary to what many think, winter doesn’t mean your garden is completely bug-free. Understanding how insect activity shift in winter can help you better prepare your garden for the colder months and support healthy biodiversity year-round.
Where Do All the Insects Go?
When temperatures drop, many insects either migrate, hibernate, or go into a dormant state known as diapause. Here’s how it works:
- Bees and Butterflies: Some species, like the monarch butterfly, migrate to warmer regions. Others, such as native bees, stay close by but hunker down in tree bark, dead stems, or underground burrows.
- Ladybugs and Lacewings: These beneficial insects seek shelter in clusters inside tree crevices, under mulch, or even in your home’s warmer corners.
- Aphids and Pests: While less active, some pests survive winter by laying eggs on plant stems or roots, ready to hatch as spring begins.
Fewer Pests, But Not Pest-Free
You may notice a decline in visible pests during winter, but many remain hidden. Slugs, mites, and even some beetles can survive in the soil or mulch. That’s why winter is an ideal time for garden cleanup—removing debris and dead plants can reduce the number of overwintering pests.
Why Winter Insects Matter
Even in their slower state, winter insects play a role in your garden’s ecosystem:
- Pollinators like bees emerge early in spring and rely on winter survival to keep their colonies strong.
- Predators such as ladybugs help control aphids when the growing season begins again.
- Decomposers continue breaking down organic matter, enriching your soil even in the cold.
Tips to Support Winter Insects
To maintain a healthy balance in your garden:
- Leave some leaf litter and hollow stems for shelter.
- Avoid unnecessary pesticide use in winter.
- Add native plants and late-blooming flowers to support insects emerging early in spring.
Winter in your garden isn’t lifeless—it’s simply resting. By understanding insect patterns this season, you’re nurturing a healthier garden come spring.
