Spiders are a sign as much as a pest: where there are spiders, there are the insects they're feeding on. Terra13's spider control service, from Terra13 Pest Control, treats house, wolf, cellar, and yellow sac spiders across Winnipeg — reducing the webs, the egg sacs, and the insect prey that keep them around.
Most Winnipeg spiders are harmless and even helpful, but heavy webbing, egg sacs, and the occasional yellow sac spider (which can deliver a nip) make them an unwelcome presence in homes, garages, and basements. Knocking down webs only helps for a day or two if the conditions that drew the spiders remain.
Because spiders follow their food, lasting control treats two things at once: the spiders and harbourage themselves, and the insect population feeding them.
The Spiders We Treat in Winnipeg
The species Terra13 handles most across Winnipeg include:
- House spiders — the classic cobweb builders in corners, ceilings, and window frames.
- Wolf spiders — large ground hunters that wander in from outside, often startling but not web-builders.
- Cellar spiders — long-legged spiders that cluster in basements, crawl spaces, and garages.
- Yellow sac spiders — pale nocturnal spiders whose bite can sting; treated with extra attention to harbourage.
Targeted Treatment Plus Prey Reduction
Terra13 applies Health Canada–approved products to targeted harbourage and perimeter zones — corners, eaves, window frames, basements, and entry points — away from where children and pets play. Webs and egg sacs are removed so the population can't rebuild.
Just as important, the perimeter treatment reduces the insect prey that spiders feed on. Cut off the food supply and seal the gaps insects use to get in, and the property becomes far less attractive to spiders over time.
