GROUND WORM (EARTHWORM) CONTROL SERVICES IN METRO VANCOUVER, BC
Ground worms, commonly known as earthworms, are normally beneficial to soil, but when large numbers migrate into basements, garages, patios, sidewalks, and building entryways, they become a nuisance across Metro Vancouver. Earthworms typically surface during wet weather or temperature changes and enter buildings through cracks, door gaps, and foundation openings.
While earthworms are not aggressive pests, their presence indoors creates sanitation, slip hazards, moisture issues, and odor concerns when they die inside buildings. Accumulated worms can attract secondary pests such as flies and beetles, especially in damp environments.
From a health perspective, earthworms present low direct risk to humans, but contact with decomposing worms or contaminated soil may expose people to bacteria such as E. coli and Salmonella. Decaying worms can also contribute to respiratory irritation and allergic reactions due to odors and organic breakdown in enclosed spaces.
At MetroVan Pest Control, we provide professional ground worm inspection, control, and prevention services. Our approach focuses on moisture management, exclusion, sanitation, and structural correction to stop worms from entering buildings.

YOU MIGHT FIND YOUR ANSWER
What are the signs of a ground worm problem?
Common signs include:
- Worms on basement floors or garages

• Targeted powder or liquid treatments near foundations
• Moisture and drainage correction guidance
• Exclusion and sealing recommendations
• Sanitation and cleanup support
This addresses the cause, not just the worms.
What health concerns are associated with ground worms?
Ground worms may contribute to:
- Exposure to bacteria such as E. coli and Salmonella through soil contact
- Respiratory irritation from decomposing organic matter
- Allergic reactions in sensitive individuals
- Secondary pest attraction when worms die indoors
Why do ground worms enter buildings?
Worms are driven indoors by:
• Excess soil moisture
• Heavy rainfall
• Temperature changes
• Poor drainage
• Gaps at ground level
They are not nesting indoors, but seeking relief from saturated soil.
How can I prevent ground worms from coming back?
We recommend:
- Improving drainage around foundations
- Reducing overwatering of lawns
- Sealing door gaps and foundation cracks
- Using door sweeps
- Keeping basements dry and ventilated
Prevention is highly effective.
Do ground worms damage property?
They do not damage structures, but they:
- Create odors

- Attract flies and beetles
- Indicate moisture problems
Do ground worm issues require multiple visits?
Most cases resolve after moisture correction and exclusion, though seasonal follow-up may be helpful.
