Where Do Woodlice Come From (1)

What are woodlice?

Woodlice are not insects but a species of crustacean that are related to shrimp and lobsters.

Unlike shrimp and lobsters that live in water, woodlice thrive on land.

They feed on decaying matters, including animal droppings, rotting fruits, and dead plants. Woodlice are somehow harmless pests because they don’t feast on living creatures.

You can easily spot them as they have an oval shape with greyish color. Furthermore, their body is segmented and made of a softshell. They are about 13mm to 15mm long with two pairs of antennae and seven pairs of legs.

Here are some answers to woodlice-related questions I put together!


Where do you find woodlice?

Dealing with woodlice isn’t easy as they can be found anywhere that is damp and covered.

However, the most common places you can find woodlice are in your garden, home, basement, and bathroom.

Let’s look at a few of these places and how you can get rid of woodlice before they reproduce themselves and infest your home.


Gardens

Woodlice are commonly found in gardens from where they can easily find their way into your home.

Most times, they usually live beneath soil and stones. However, you can see woodlice in your home as well.

Generally, their natural habitat is the garden; they live under rotting leaves, dead wood, stones, plants, and stumps.

While woodlice don’t harm the plants in your garden, they carry diseases that can transfer through your pets.

Woodlice are different from other insects that you can easily control using traps or spraying something around your surroundings.

A mulch bed, for instance, is one of the best breeding grounds for woodlice since they like moist environments. You can spray insecticides around this area but be warned; it doesn’t discriminate! It will kill lots of insects in that mulch bed too.


Basement

If your basement is damp or you live in an area with moisture, you may easily find woodlice in these areas.

Your basements or damp spots will attract woodlice because they love being anywhere close to water sources.

You have a totally different situation if you observe woodlice inside your basement or bathroom. The best way is to remove their eggs to avoid reproduction in the affected area.

Another option is to use a fan or dehumidifier to minimize the humidity in your basement.

It might be a good idea to keep your humidity level below 60% to reduce the chances of infestation in your home.


Home

You can also find woodlice in your home if your surroundings are damp. Mold, rotting items, and damp wood are what attract them the most.

In the worst case, you might find them eating paper, including wallpaper, inside your home. One of the first things to do to avoid woodlice from entering is to ensure you remove any vegetation within the perimeter of your home.


Treatment Woodlice at home

As mentioned earlier, woodlice are pests you see mostly outside but can gain access to your home. In most situations, you will find them outside the perimeter of your building.

However, to minimize woodlice indoors, it is advisable to remove any tubs or pots from the wall of your home. These are known for serving as breeding nests for woodlice.

In addition, you need to seal any cracks in your home while sealing door frames and windows as well, using a mastic sealant.

You can also remove any vegetation close to your home, especially plants that grow close to your wall from the outside. These will attract woodlice close enough to your home to be a potential problem.

There are also chemical methods to control woodlice, but that can be very toxic to the environment and health. Always consult a professional pest control technician if you want to go this route.


Outdoor Control Measures

Dealing with woodlice shouldn’t cost you much money. You can do some things outside your home to reduce the chances of getting a woodlice infestation.

  • Clear your gutter regularly
  • Keep your drains free of any debris
  • Fix any water leakages near or inside your home
  • Apply insecticide to your plants near your home
  • Do not store any wood or rotting materials near your home

General Tips for Removing Woodlice

If you find woodlice in your basement, garden, or bedroom, the first thing to do is remove hiding places.

Allow the soil to dry (if you can) since they like to hang around damp areas. Furthermore, remove any dead plants and trash around your house; you can also check if you have any firewood and remove it.

You can also seal any cracks in your walls to avoid points of entry.

Use anti-insect spray. If you have kids and pets in your home, this might be very toxic, so always read the instructions first and adhere to them.

Alternatively, you can use electronic pulsing devices that emit high-frequency waves to repel any pest around your home. Some folks I know have had success when using these to control pests such as woodlice.


Conclusion

Woodlice are household pests that can be a pain if left.

They like dark and damp places, so you can easily find them hiding in compost heaps, under stones, and in the walls.

Usually, woodlice get attracted by moist areas and enter your home as they wander around your premises.

Although being very common, they are actually harmless, unlike other household pests. Furthermore, they don’t transmit diseases, bite, or sting.

Nevertheless, if you have wallpaper in your home that is moist, it can become a feasting place for those little creatures. That is why it is essential to make sure your home and surroundings are woodlice-free, as it is much harder to get rid of them once they have already infested your premises.

Good luck!
