As Halloween approaches, plastic spiders invade our decorations, but what do you do when real spiders take up residence in your home? As temperatures plummet in Quebec, these eight-legged creatures seek refuge in our warm homes. Knowing how to recognize the signs of an infestation can save you a lot of trouble.
Spider Webs: More Than Just a Halloween Decoration
Unlike the fake webs you put up to scare your little costumed visitors, real spider webs in your home indicate an active presence. One or two occasional webs are normal, but when you start noticing them regularly in ceiling corners, behind furniture, in the basement or garage, it’s a warning sign.
Abandoned, dusty, and gray webs are evidence that spiders have been active recently. Fresh webs, with their shiny, strong threads, indicate current occupancy. If you clean regularly and webs appear quickly in the same location, you are dealing with an established population.
Direct observation of numerous spiders
Occasionally seeing a spider does not constitute an infestation. However, certain behaviors should raise alarm bells:
- Frequent sightings: You encounter spiders several times a day or in different rooms
- Daytime presence: Spiders come out during the day, a sign that their numbers are high
- Specimens of various sizes: The simultaneous presence of adult and juvenile spiders indicates active reproduction
- Concentration in certain areas: Basements, attics, storage spaces, or closets become their favorite refuges.
Egg sacs: The invisible threat
Egg sacs are the most worrying sign of an infestation. These small, silky structures, often beige or white, contain hundreds of eggs. A single sac can release between 100 and 300 baby spiders.
You’ll usually find them in dark, undisturbed places: behind picture frames, in closet corners, under furniture, or in wall cracks. Their presence confirms that spiders are actively breeding in your property.
Accumulation of Dead Insects
Spiders often leave the remains of their prey near their webs. If you regularly discover the carcasses of flies, mosquitoes, or other insects in certain areas, it’s a sign that a spider is actively feeding there.
Spider Droppings
Although less well-known, spider droppings are a reliable indicator of infestation. They appear as small dark spots on walls, near baseboards, or around webs. These marks resemble ink splatters and accumulate where spiders are active.
Why Quebec’s autumn favors infestations
With the arrival of the cold fall weather, spiders that used to live outdoors seek the warmth of our homes. This seasonal migration explains why so many Quebec homeowners notice an increase in their presence in October and November. Cracks in the foundation, poorly sealed doors and windows, and unprotected vents become their entry points.
The Importance of Professional Intervention
Although spiders play an important ecological role outdoors by controlling insect populations, an indoor infestation requires rapid action. Homemade treatments rarely offer lasting results because they don’t address the source of the problem. professional exterminators have the expertise to:
- Accurately identify the species present and their level of danger
- Locate all entry points and nesting areas
- Apply targeted and safe treatments for your family and pets
- Implement preventative measures to avoid recurrences
- Ensure long-lasting results with proven methods

Frequently Asked Questions
1. How long does it take for a spider infestation to develop?
An infestation can develop in a few weeks to a few months, depending on the species and conditions. Spiders reproduce quickly when they find a favorable environment with abundant food, warmth, and quiet areas. A single fertilized female can produce hundreds of offspring.
2. Are house spiders in Quebec dangerous?
Most Quebec spiders are harmless to humans. Common species such as the house spider or the pholca rarely cause bites. Even if a bite occurs, it usually causes mild irritation similar to a mosquito bite. Serious reactions are extremely rare.
3. Can a spider infestation attract other pests?
No, it’s the other way around. Spiders feed on insects, so their massive presence often indicates that another insect infestation (flies, ants, woodlice) already exists. Eliminating only the spiders without treating the food source will rarely solve the problem in the long term.
4. Do natural spider repellents really work?
Natural repellents such as peppermint, citrus fruits, or horse chestnut have limited and temporary effectiveness. They may deter a few spiders locally, but are not a reliable solution for an established infestation. Their effect fades quickly and requires frequent applications.
5. Can spiders damage my home or property?
Spiders do not cause structural damage like termites or carpenter ants. They do not eat wood, fabric, or other materials. Their impact is mainly limited to unsightly webs and the psychological discomfort they can cause to occupants.
