Types of Spiders We Remove in Markham
Giant House Spider
Eratigena atrica
Large, fast and brown. Builds funnel webs in basements, garages and window wells, and wanders indoors in late summer looking for mates.
Cellar Spider
Pholcus phalangioides
Long thin legs and a small body. Fills ceiling corners, crawl spaces and laundry rooms with loose, messy webs.
Wolf Spider
Lycosidae family
Hairy, ground-hunting spider that does not spin webs. Common in basements, ground-floor units and garages near grass and gardens.
Yellow Sac Spider
Cheiracanthium mildei
Pale yellow hunter that hides in silk sacs in wall corners and ceilings. One of the few house spiders whose bite can leave a sore welt.
Dark Fishing Spider
Dolomedes tenebrosus
Very large spider found near ravines, creeks and damp basements. Startling size but shy and rarely bites.
Northern Black Widow
Latrodectus variolus
Rare in the city but present in southern Ontario. Glossy black with a red mark. Lives in woodpiles, stone walls and sheds, often confused with the more common false black widow. Do not handle it.
Signs You Need Spider Control in Markham
- Webs that come back in corners, ceilings and windows
- Round, papery egg sacs tucked into webs
- Spiders in the basement, garage or laundry room
- Funnel webs in window wells and around the foundation
- Webs clustered around exterior lights and balconies
- Spiders crawling on walls or floors at night
- Lots of other insects indoors, which spiders feed on
- Bite marks after time in the basement or storage areas
A few spiders are normal. Webs that return within days, egg sacs, or spiders showing up in bedrooms and kids' rooms mean an established population with a steady food source. Store-bought sprays kill the spider you see, not the egg sacs or the insects that keep feeding them.
Spider Problems in Markham
Homes backing onto Rouge National Urban Park, Milne Dam Conservation Park and the Rouge River see wolf spiders and fishing spiders wander indoors each fall. Heritage houses in Unionville and Markham Village have stone foundations with many small gaps, and newer townhomes in Cornell share garages where cellar spiders and giant house spiders spread between units.
Our Spider Control Process
Free spider inspection
We identify the species, find where they nest and locate the insects they feed on and the gaps they use to get inside.
De-webbing and egg sac removal
We vacuum and remove webs and egg sacs from basements, garages, eaves, window wells and exterior walls.
Crack and crevice treatment
We apply Health Canada registered products and insecticidal dust where spiders hide: baseboards, wall voids, sill plates and storage areas.
Exterior perimeter barrier
We treat the foundation, doors, windows, soffits and light fixtures so spiders are stopped before they reach the house.
Sealing and follow-up
We point out and seal small entry points, then check back to confirm the activity has stopped.

How Much Does Spider Control Cost in Markham?
Most spider jobs are a single treatment visit plus a follow-up check. The price depends on the size of the home, how many levels and outbuildings need treatment and how heavy the activity is. You get a fixed quote after the free inspection, before any work starts. For year-round protection against spiders and the insects they eat, our home protection plans start at $39 per month.
How to Keep Spiders Out After Treatment
- Vacuum webs and egg sacs weekly in basements, garages and corners
- Seal gaps around windows, doors, pipes and dryer vents
- Switch exterior bulbs to yellow LED lights that attract fewer insects
- Keep firewood, bins and boxes away from the foundation
- Store items in sealed plastic bins instead of cardboard
- Run a dehumidifier in damp basements
Spider Control FAQ
Straight answers from our licensed technicians. Still have a question? Call (647) 471-1332, we are open 24 hours.
Are spiders in Markham dangerous?
Most spiders found in Markham homes are harmless and their bites are rare. The northern black widow is the main exception: it is uncommon but present in southern Ontario. If you see a glossy black spider with a red mark, do not handle it and call us for safe removal.
How long does spider treatment take?
A typical home takes 45 to 90 minutes for the interior and exterior treatment. You can usually return to treated rooms once surfaces are dry, which is about 2 to 4 hours.
Why do I see more spiders in late summer and fall?
From August to October, male house spiders wander indoors looking for mates, and cooler nights push outdoor spiders toward warm foundations. That is the best time to book a perimeter treatment.
Is spider treatment safe for children and pets?
Yes. We use Health Canada registered products applied by licensed technicians, focused on cracks, voids and the exterior. We tell you exactly when each area is safe to use again.
Will the spiders come back?
Our treatment removes egg sacs and leaves a residual barrier, and we seal the entry points we find. If spiders return within the warranty period, we come back at no charge.
Do you also remove spider webs outside?
Yes. We de-web eaves, soffits, decks, balconies and exterior lights as part of the service, then treat those areas so webs do not rebuild quickly.
Do you treat heritage homes in Unionville?
Yes. We use targeted, low-impact treatments suited to older homes and finishes.
Do you treat commercial buildings in Markham?
Yes. We offer perimeter and de-webbing programs for offices, plazas and warehouses.
