SPIDER SPECIES WE TREAT

The 4 spider species we treat most across Winnipeg & Manitoba

Most spiders in Winnipeg homes are harmless — but they leave webs everywhere and signal a larger insect problem. Accurate ID drives the right treatment for each species and the underlying prey insect.

WARNING SIGNS

Signs you need professional spider extermination in Winnipeg

Killing visible spiders won't stop the population. They are feeding on something in your walls, baseboards, or basement, so treatment must address both spiders and their prey.

Cobwebs in corners, ceilings, behind furniture, or around lights
Multiple live spiders spotted indoors over days or weeks
Spider egg sacs — small white silk balls tucked into dark corners
Wolf spiders sprinting across floors as autumn temperatures drop
Web build-up in basement corners, window wells, or eaves
Flies, moths, or ants on the same surfaces — spider prey
OUR PROCESS

Our 4-step spider extermination process in Winnipeg

A predictable sequence from species identification through web removal, targeted residual treatment, and entry-point prevention.

01

Identify

Identify the species, locate web hot-spots and harbourage points, grade activity, and inspect the prey insects keeping spiders fed.

02

Target

Knock down active webs, sweep egg sacs, and apply residual treatment to baseboards, corners, window frames, and entry points.

03

Protect

Apply Health Canada-approved products to crack-and-crevice zones. People and pets return after treated surfaces are fully dry.

04

Prevent

Seal entry points, treat prey insects, advise on lighting and landscaping, and include a free re-treatment warranty.

LOCAL CONDITIONS

Why spiders thrive in Winnipeg homes and basements

Winnipeg's long cold winters drive prey insects indoors, and spiders follow. Wolf spiders and house spiders push into basements, garages, and ground-floor apartments from September onward, looking for warmth, prey, and dark harbourage.

Older homes in River Heights, Wolseley, and Crescentwood have decades of foundation cracks and rim-joist gaps that spiders use as entry highways. We address those entry points along with the spiders.

AFTERCARE

How to keep spiders out of your Winnipeg home

Spider treatment kills the visible population and the prey insects supporting it. These habits stop the next population from settling indoors.

  1. Vacuum corners, window frames, and basements weekly to break web build-up.
  2. Swap bright white outdoor bulbs for yellow LED bulbs that attract fewer prey insects.
  3. Seal cracks around windows, doors, foundations, and rim joists with caulk or steel wool.
  4. Trim shrubs and grass back at least 30 cm from the foundation.
  5. Reduce indoor clutter because boxes and stored fabrics provide harbourage.
  6. Treat the prey first: ants, flies, and silverfish keep spiders fed indoors.
