Know the signs

Signs of Sow Bugs

Sow bugs are grey, oval crustaceans, not insects. They need damp, dark places to survive, so where you find them says a lot about moisture.

Grey bugs on basement floors

Small, flat, grey bugs with segmented shells moving across concrete floors, often after rain.

Activity after heavy rain

Sudden numbers indoors after a storm or snowmelt, when wet soil pushes them toward the foundation.

Clusters under damp items

Groups under flower pots, firewood, mulch, rocks or wet cardboard near the house.

Bugs around doors and windows

Sow bugs near basement doors, window wells, garage doors and utility openings.

Damp, musty areas

Wet crawl spaces, leaking downspouts or soil that stays soggy next to the foundation.
How we treat it

Our Sow Bug Treatment Options

We use two methods, sometimes together. The choice depends on whether activity is inside or outside and where sow bugs are entering: the foundation, crawl space, basement or landscaping.

Chemical Spray Treatment

A residual spray goes where sow bugs are active, entering or hiding: foundation walls, door and window frames, vents, utility openings and, where needed, interior cracks and baseboards. Outside, it forms a treated barrier around the building.

Best for: Most sow bug problems around homes and buildings, inside or outside.

Fogging Treatment

Fogging reaches enclosed or hard-to-treat spaces such as crawl spaces, unfinished basements and utility areas where sow bugs gather in larger numbers. It reduces exposed sow bugs in that area but does not replace moisture correction or sealing.

Best for: Heavy activity in crawl spaces, unfinished basements or other enclosed areas.

What to expect

How Sow Bug Control Works

Contact us

Call or email our Edmonton or Calgary team. Tell us where you are seeing sow bugs: basement, crawl space, garage or outside.

Inspection

A licensed technician inspects inside and outside, finds likely entry points and notes the moisture conditions that support sow bugs.

Treatment plan and quote

We recommend a spray treatment, fogging or a combination, explain the reasons and give you a quote and any preparation steps.

Treatment

We treat entry points, harbourage areas and, where needed, interior cracks and enclosed spaces. Our vehicles and equipment are unmarked.

Follow-up and moisture advice

We review the moisture and drainage fixes that keep sow bugs from returning, and schedule a follow-up visit if activity continues.
Why it matters

Why Sow Bugs Keep Coming Back

Sow bugs do not bite or eat healthy plants. The concern is what they signal: damp soil, poor drainage, leaking gutters or a wet crawl space next to your foundation. Those same conditions can lead to mould and wood rot. Treatment lowers the numbers, but fixing the moisture is what keeps them out.

How to Prevent Sow Bugs

Pull mulch back

Keep mulch, leaves and debris away from the foundation so the soil next to the house can dry.

Move water away

Fix leaking gutters and add downspout extensions so water drains away from the walls.

Dry the basement

Run a dehumidifier in damp basements and crawl spaces and improve ventilation where you can.

Seal and store

Seal cracks and gaps at the foundation. Keep firewood and lumber off the ground and away from the house.
Common questions

Frequently asked questions

How do you treat for sow bugs?

Indoors, we use residual sprays and dusts along baseboards, cracks and entry points. Outdoors, a perimeter spray around the foundation reduces breeding sites and entry. In crawl spaces or unfinished basements with heavy activity, fogging may be added. We also point out moisture fixes.

What is the difference between sow bugs and pill bugs?

They look almost the same and live in the same damp places. Pill bugs roll into a tight ball when disturbed. Sow bugs only curl slightly and have two small tail-like points at the back. Our treatment approach is the same for both.

Why do I see so many sow bugs after rain?

Heavy rain and snowmelt soak the soil and push sow bugs out of the ground. If there is moisture near your foundation, they move toward the house looking for more damp cover. Improving drainage is the lasting fix.

Is the treatment safe for pets and children?

Products are applied to cracks, entry points and the foundation, not where your family spends its time. Treated areas are safe for people and pets once dry, when applied as directed. We will tell you how long to keep pets and children away.
