Do woodlice prefer dark or light?

In their natural environment, woodlice are found in damp, dark places (e.g. under stones and amongst rotting wood/leaf litter). They dry out quickly in dry air (e.g. in the open and/or in bright sunlight). For example, woodlice are more active in dry conditions and less active in damp conditions.

Why do woodlice like dark conditions?

Woodlice do not have a highly developed nervous system but do show some basic forms of behaviour. They have a relatively high surface area to volume ratio and lose water through their surface. This type of behaviour is called kinesis and results in woodlice accumulating in the dark and damp conditions that they prefer.

Are woodlice sensitive to light?

Woodlice can detect black/light contrasts (Meyer-Rochow, 2001), and could even see under low light intensities (Nilsson & Nilsson, 1981).

What conditions do woodlice like?

Woodlice like damp, dark places and can be found hiding in walls, under stones and in compost heaps. Some species such as the common sea slater are only found on the coast.

Why do woodlice prefer moist?

While most crustaceans live in water, woodlice live on land but breathe through gills like fish. Their gills need to be covered with a thin layer of water to work well, so they prefer to live in places with a lot of moisture.

How do I get rid of a woodlice infestation?

How to get rid of woodlice in your home

1. Vacuum them up. This is the simplest way to deal with a woodlice invasion and the first stage to getting rid of them in your home.
2. Anti-insect spray. Use an anti-insect spray in the areas where you are finding the woodlice.
3. Seal up the holes.
4. Try an electronic pulsing device.

Why do woodlice clump together?

Woodlice tend to move quicker in dry places than damp places. You may also see them ‘clump’ together. This helps them to reduce their water loss as it reduces the surface area that is in the open air, as by less air passing their outer layer, less water is lost in that way.

What Behavioural response does a woodlouse take when it is in danger?

Woodlice have several behavioural adaptations that help them to survive and reproduce. If they detect a threat they roll themselves up into a ball, so they are surrounded by exoskeleton.

Do woodlice like the cold?

When the weather gets warmer, woodlice search for damp, cooler spots to live in. You may not think your home is damp and cold, but for them, a slightly rotting window frame or skirting board can be perfect.

Do woodlice bite humans?

Warm and damp habitats with plenty of crevices are favourites, including rotting wood, brick walls and even cellars. This spider’s jaws are strong enough to give humans a painful nip if handled.

Why does a woodlice live in the dark?

They have this ability because they possess light receptors (ocelli) that are sensitive to levels of illumination. In their natural environment, dark places are normally damp places whereas bright places tend to be drier and warmer.

What does a woodlice do in a choice chamber?

You can state that woodlice do have a preference for one set of conditions over another. Animal behaviours in choice chambers may show directional responses (movement directly towards or away from particular stimuli), or may show behaviours such as increasing speed and increase in turning rate.

What’s the best way to keep woodlice alive?

Keep the container covered to exclude light and retain moisture. Place it in a relatively cool and sheltered place out of direct sunlight. Keep the soil moist but not waterlogged. Put a variety of stones, bark and rotting wood on the soil for the woodlice to live in.

How many observers do you need for a woodlice?

Place one or two woodlice in the choice chamber. Each woodlouse needs a different observer. If two woodlice are used it helps if they look different and you can tell them apart, even if they move close to one another.
