Table of Contents

In this post, we'll discuss everything there is to know about woodlice, including their behavior, their effects on your garden, and what you can do to prevent them.

Woodlice are common insects that are found in gardens across the world. They belong to the group of crustaceans and are related to crabs, lobsters, and shrimps. Woodlice thrive in damp, dark environments and they feed on decaying organic matter such as dead plants and fungi.

What are woodlice?

Woodlice are small, black or greyish-brown insects with a hard exoskeleton. They have seven pairs of legs and two antennae. Unlike other insects, they cannot fly or jump. They move slowly and curl up into a ball when threatened, which gives them their nickname “pillbug”.

Where do they live?

Woodlice live in moist environments such as gardens, where they can often be found under rocks, logs, and flower pots. They prefer cooler temperatures, which is why they are more active at night.

Signs of woodlice infestation under garden pots

One sign of woodlice infestation is finding them crawling around under garden pots or other containers. Another sign is seeing damage to plants near containers or pots, which can be caused by woodlice eating roots or leaves.

Woodlouse habits

Understanding the habits of woodlice is key to preventing them from causing damage in your garden.

Food source:

Woodlice eat a variety of things, including decaying plant matter, dead animals, and fungi. They also feed on living plants, although this is less common. In a garden, they may target root systems or feed on tender stems and foliage.

Behavior:

Woodlice are nocturnal and will often hide during the day in damp places such as under leaves, rocks, and flowerpots. They prefer cooler temperatures and will avoid areas that become too hot or dry.

Reproduction:

Woodlice reproduce sexually, and females carry their eggs in a brood pouch until they hatch. They can lay up to 200 eggs at a time, which hatch within about six weeks. The larvae look like miniature adults but are much lighter-colored and have fewer legs.

Harmed caused by woodlice in gardens

While woodlice may not be harmful to humans, they can cause damage to plants and garden structures.

Plant damage:

As mentioned earlier, woodlice can feed on plant roots and stems, causing damage to young seedlings, vegetables, and flower beds. They often target weak or sick plants but can also attack healthy ones.

Household Damage:

In addition to damaging plants, woodlice can also harm outdoor furniture and wooden structures. They have been known to gnaw on wood and may create tunnels that weaken the structure.

Health Risks:

While woodlice themselves are not harmful to humans, they can carry bacteria and other pathogens that can make us sick. They are also a potential allergen for some people.

How to prevent woodlice damage

There are several ways to prevent woodlice from causing damage in your garden.

Improve garden hygiene:

Clean up any dead plant material or debris in your garden. Woodlice feed on decaying organic matter, so removing it will help deter them.

Reduce excess humidity:

Woodlice thrive in moist environments, so reducing excess humidity around your garden can help discourage them. Consider using a dehumidifier in enclosed spaces or installing a gutter system that prevents water from pooling near your plants.

Natural predator control:

Many natural predators of woodlice, such as birds and hedgehogs, will eat them if they come across them in your garden. Consider planting hedges, bushes, and trees that attract these animals to your garden.

Pesticide control:

If natural methods are not working, using an insecticide can be effective in controlling woodlice infestations. Be sure to follow the instructions on the label when applying pesticides.

In woodlice are common garden pests that can cause damage to plants and structures. By taking the proper precautions, such as maintaining a clean and dry environment, using natural predators, or pesticides, you can easily prevent them from doing harm to your garden.
