It’s winter. The garden looks quiet and peaceful, with bare branches and a layer of frost on the grass. You might think that all the uninvited guests have neatly retreated. But then – sliiiiime ! A sudden slippery discovery under that pile of leaves. Yes, slugs can play a role even in winter. How? Let’s find out!
Are slugs active in winter?
Most people associate slugs with spring and summer, when it is humid and warm, and everything is in bloom. But don't underestimate them; slugs are tough guys. Although they are less active in winter, they don't disappear completely. As soon as the mercury rises above 5°C, they can crawl out of their hiding places and start looking for food. Especially during mild winters, which we have had more and more of in recent years, they remain a potential pest.
Where do they hide during the winter?
Slugs are smart (or maybe just lazy). They seek shelter in damp, dark places where they are protected from the cold. Think of piles of leaves, compost heaps, under tree bark, or even in your greenhouse. These places not only offer shelter, but often a tasty snack or two.
Is your garden safe during frost?
When temperatures drop below freezing, slugs have a hard time. Many of them die or retreat deep into the ground to hibernate. However, they lay eggs for the winter that can be frost-resistant. And yes, as soon as spring arrives, those little slug babies emerge, ready to feast on your plants. Nice prospect, huh?
What can you do to keep them under control?
Fortunately, you can do some prep work during the winter to prevent an invasion in the spring. Here are a few tips:
- Clean up, but in moderation : Clear away loose leaves and garden waste, especially near vulnerable plants. But also leave some natural hiding places for beneficial insects.
- Check your greenhouse : Do you have a greenhouse? Slugs love the constant temperature inside. Make sure there are no damp places for them to hide.
- Use slug pellets : For those who want to add an extra layer of protection, slug pellets can be a handy option. Preferably choose ecologically responsible slug pellets that are safe for pets and other animals. These pellets are effective and can even be used preventatively in the winter.
- Nematodes in stock : Start thinking about using nematodes as soon as the temperatures rise. They are the natural enemies of slugs and help keep your garden healthy. ( And yes, we know where to find them 😉 ).
Winter-ready with peace of mind
Although slugs aren’t as active in the winter as they are in warmer months, they’re certainly not gone. With a few simple steps, you can make sure your garden doesn’t look like a slug buffet come spring. So, grab those gardening gloves and get winter-ready. Because a little bit of preparation can save you a lot of garden heartache in the new year.
