What are woodlice?
Woodlice are small crustaceans, more closely related to crabs and shrimp than to insects. They're typically grey or brown with a segmented body, and some species roll into a ball when disturbed. They feed mostly on decaying plant material.
Why you're finding them indoors
Woodlice lose moisture quickly, so they stay in damp, dark places. Indoors, they usually turn up where something is wet:
- Leaking pipes, taps or air-conditioning drip areas.
- Damp corners, bathrooms and laundry rooms.
- Damp, rotting wood or cardboard.
- Poor ventilation in closets and storage rooms.
- Heavy rain pushing them in from outside.
Outdoor attractions near the building
- Leaf litter, mulch and plant debris piled against walls.
- Pots, mats and stacked items that stay damp underneath.
- Poor drainage that leaves soil wet near the foundation.
Are they harmful?
Woodlice don't bite or sting, and they generally aren't a health risk. They're mostly a nuisance. But because they point to moisture, they can be a clue to a bigger problem, such as a leak or damp that could damage wood and attract other pests.
What you can do
- Find and fix leaks, and dry damp areas.
- Improve ventilation with fans, open windows and dehumidifiers where needed.
- Clear debris, leaf litter and mulch from the base of walls.
- Move pots and items off damp ground, and make sure water drains away from the building.
- Seal gaps around doors, windows and pipes.
Removing the moisture is usually the real fix. Treating the woodlice without fixing the damp is likely to bring them back.
When you should call a pest control company
- You keep finding woodlice indoors.
- You can't find the source of the moisture.
- You see other pests along with the damp.
- You're concerned about damp near timber.
What happens at an inspection
A technician checks inside and outside the property, looks for signs of activity, works out where pests are getting in and what is attracting them, and explains what was found. You then get a clear recommendation. Protek Pest Services offers a free, no-obligation inspection across St. Kitts & Nevis.
Frequently asked questions
Are woodlice the same as pill bugs and slaters?
They're closely related names. Woodlice, slaters, pill bugs and roly-polies are often used for similar small creatures, though they're not all exactly the same species.
Do woodlice damage homes?
They mainly feed on decaying material, so they aren't usually a structural pest. But the damp they point to can damage wood.
Will they go away on their own?
If you fix the moisture, many will leave or die off. If the damp stays, they tend to stay too.
