Why Do I Have Spiders In Calgary?

Many people are repulsed by and afraid of spiders. Spiders can cause psychological distress and the condition arachnophobia. They gain entry to homes and businesses utilizing cracks, gaps, and holes in and along walls and doors. Typically spiders prefer to build their webs in dark and quiet areas such as basements and garages. 

The majority of spiders found in Canada are harmless. Only two species of venomous spiders are found in Canada, the brown recluse spider and the black widow spider. If you see any spider in your home, be sure to contact Major Pest Control so they can take care of it for you.

Types Of Venomous Spiders Around Calgary

Brown Recluse Spider: The brown recluse (Loxosceles reclusa), is a recluse spider with necrotic venom. Similar to those of other recluse spiders, their bites sometimes require medical attention. Brown recluse spiders are usually between 6 and 20 mm, but may grow larger. While typically light to medium brown, they range in color from whitish to dark brown or blackish gray.

Brown recluse spiders build asymmetrical webs that frequently include a shelter consisting of disorderly threads. They frequently build their webs in woodpiles and sheds, closets, garages, plenum spaces, cellars, and other places that are dry and generally undisturbed. When dwelling in human residences they seem to favor cardboard, possibly because it mimics the rotting tree bark which they inhabit naturally.

Black Widow Spider: Latrodectus hesperus, the western black widow spider or western widow, is a venomous spider species found in western regions of North America. The female’s body is 14–16 mm in length and is black, often with an hourglass-shaped red mark on the lower abdomen. This mark can be yellow, and on rare occasions, white. The male of the species is around half this length and generally a tan color with lighter striping on the abdomen. Female black widows have potent venom containing a neurotoxin active against a range of mammals.

What months are spiders active?

Spiders’ activity level depends on the species. The common black and yellow orb weavers frequently seen in the garden are most active in late summer into fall, as are most common house spiders. Cellar spiders, on the other hand, are active throughout the year.

Are Calgary spiders dangerous?

Generally spiders found in Canada may bite a human if they perceive a threat or if disturbed when concealed in clothing like shoes or gloves. For many people, spiders can contribute to psychological distress, especially those suffering with arachnophobia. The presence of spiders can diminish the aesthetics of your home or building. Rather than being especially hazardous, spiders are typically more of a nuisance.

Are there venomous spiders in Calgary or Canada?

The majority of spiders one encounters in Canada are non-venomous. There are two notable exceptions: the brown recluse spider and the black widow spider. Sometimes a non-native venomous spider can sneak in when hiding in shipping containers from other countries.

A common misconception persists that bites from a venomous spider from Canada are deadly, however fatalities from spider bites are extremely rare. The most common symptoms following a spider bite are swelling, pain, and cramping. For the bites of a brown recluse, often a small area of necrotic tissue will develop at the site of the bite. Most spider bites appear identical and so it is difficult to identify a spider species based on the bite alone.

Why do I have a spider infestation in my home?

Many spiders prefer dark and moist environments, often making homes in caves, tree hollows, shrubs, soil, or under rocks. In homes, you’ll often find spiders making their webs in basements, garages, and other dark, quiet spaces. They get in your home through cracks and holes in your walls or open doors.

In general, most spiders choose to live in dark and damp conditions such as in caves, tree hollows, shrubs, soil, and beneath rocks. When indoors, spiders frequently construct their webs in garages and basements or other dark and undisturbed areas. Spiders invade your home utilizing cracks and gaps in walls or through open doors. Detecting one spider is not necessarily indicative of a spider infestation. Most spiders lead solitary lives, and some may live up to 15 years. 

How worried should I be about carpet beetles?

Carpet beetle larvae can damage carpets and fabrics by eating irregular holes into them as well as damage wool, silk, feathers, and leather by consuming entire chunks. Carpet beetle larvae have bristly hairs that may cause skin irritation. Additionally, the molted skins of larvae can cause allergic reactions and dermatitis in susceptible individuals. Eradication of a carpet beetle infestation is best achieved by employing the services of a trusted and reputable professional pest control company, like Major Pest Control.

How can I stop spiders from entering my home?

Because spiders typically gain entry into homes via cracks and gaps, start with keeping windows and doors closed and sealed to prevent them from entering. Also use caulk or sealant to repair any foundation cracks or gaps. Preventing other insects from entering your home also discourages spiders from taking up residence. Another tactic is to remove existing spider webs. Dehumidifiers remove humidity from air in basements which makes the environment less attractive to spiders.
