How to get rid of Edmonton Spiders?

During the summer in Edmonton, an array of spiders emerges, and while most spiders are harmless, there are a few notable exceptions to be cautious of, including the Black Widow, the Brown Recluse, and the more common Hobo spider. These spiders often hitch a ride on shipments of fruit and vegetables from various exotic locations. If you happen to be bitten, the most severe symptoms you might experience are nausea, itching, or swelling in the affected area. Maintaining a clean home and regularly clearing away spider webs is a proactive measure to keep these eight-legged creatures at bay.

Common Canadian household spiders include house spiders, wolf spiders, cellar spiders, fishing spiders, and, less frequently, black widow spiders. You can find them in room corners, closets, boxes, dark crevices, basements, garages, and gardens.

Spiders possess an unsegmented body with two primary divisions and four pairs of legs. They also produce silk, which is used for constructing nests, prey-catching webs, or egg cocoons.

Most spiders are insect predators, targeting various pests. When their prey gets ensnared in their webs, spiders immobilize it by wrapping it in additional silk and injecting venom to paralyze it. Subsequently, they introduce a predigested liquid and extract the nutrients. However, not all spiders spin webs, and there are various spider species that employ different hunting strategies.

Types of spiders

Wolf spiders

Although spiders can possess up to eight eyes, it may come as a surprise that most of them are actually near-sighted.

Wolf spiders stand out due to their unique behavior; they don’t construct webs but instead actively hunt for prey. These spiders can reach sizes of up to 3 cm (a little over 1 inch) in length and typically sport a dark brown hue. They are commonly spotted on the ground in environments such as grasslands, woodland floors, beaches, and gardens, where they primarily feed on insects. During the autumn season, they seek warmer locations, making it more likely for them to enter our homes during this time.

Cellar spiders

Cellar spiders, characterized by their notably lengthy legs, construct their webs in the corners of cellars or in cool, damp basements. These spiders are entirely harmless and can be managed by removing their webs and decreasing the humidity levels in that particular area of your home.

Cellar spiders are sometimes referred to as daddy-long-leg spiders, and they can occasionally be mistaken for another arachnid relative commonly known as the harvestman or daddy long-legs. It’s important to note that the harvestman lacks the two distinct body parts typical of true spiders, and it doesn’t possess silk-producing glands. However, it does have four pairs of slender, elongated legs, which can initially give the impression of a spider.

House spiders and black widow spiders

House and black widow spiders belong to the same family. House spiders are commonly found indoors, while black widow spiders tend to inhabit dark crawl spaces, garages, or outhouses. House spiders come in various colors, ranging from dirty white to nearly black, often marked on their bodies. Their first pair of legs can be up to three times the length of their bodies. They construct webs in dim corners, beneath furniture, and other places to catch insects.

Black widow spiders are rare in Canada, primarily located in southern regions along the Canada-United States border. They are shiny black with a distinctive red hourglass-shaped mark on their abdomens’ undersides. These spiders create small silk webs close to the ground, favoring secluded areas such as garages, sheds, or under rocks or fallen trees outdoors. Black widows are not typically aggressive and will usually flee when disturbed; they only bite in self-defense.

While a few black widow species can be found in Canada, particularly in the southern regions, they are not prevalent. If you’re concerned about the potential presence of black widow spiders, exercise caution when working near spider webs in isolated areas and consider wearing protective gloves if necessary.

Fishing spiders

Fishing spiders, despite their resemblance to wolf spiders, exhibit a distinct eye pattern. Adult fishing spiders can attain widths of up to 7.5 cm (3 inches). They are frequently sighted near cottages and waterfronts, particularly in the vicinity of rocks along the shoreline. These spiders hunt for prey, which includes insects and minnows. A key difference from wolf spiders is in their egg sac carrying behavior; fishing spiders bear their egg sac beneath their head and front thorax, whereas wolf spiders carry theirs behind their body.

Should Edmontonian be concerned?

Spiders serve as valuable allies in pest control. Among them, wolf spiders play a particularly beneficial role for farmers and gardeners, as they target common crop pests such as caterpillars, plant bugs, and aphids.

It’s important to note that spiders do not transmit diseases. While most spiders possess venom glands, they rarely bite humans, and only a few species, like the black widow spider, may deliver a venomous bite, which is typically not fatal. The majority of spiders are nocturnal, timid, and prefer to flee rather than confront a threat. They will only resort to biting when they perceive a direct threat, such as being squeezed or restrained.

The severity of a reaction to a black widow spider bite depends on factors like the bite location, the amount of venom injected, and an individual’s sensitivity to the venom. Instances of severe long-term complications or fatalities are extremely rare. If bitten, it is advisable to stay calm and seek immediate medical attention by contacting your doctor, hospital, or poison control center. Applying an ice pack directly to the bite area can help alleviate swelling and pain.

How can I get rid of spiders?

Prevention

Maintaining a clean home serves to decrease the presence of pests, which, in turn, function as a food source for spiders. To deter pests from infiltrating your residence, take steps such as weather stripping or caulking your windows and doors, and promptly repairing any damaged screens. When tending to cleaning tasks in your garage, basement, or while working in your garden, it is advisable to don gloves to minimize the risk of unintended spider bites. It’s important to note that spiders, for the most part, offer valuable contributions; allowing a few spiders to inhabit your basement and crawlspaces can aid in capturing pests like earwigs and other insects.

Physical Control

Avoid resorting to chemical means for complete spider eradication, as spiders serve as natural and effective pest controllers. Choose Classic Pest Control for your spider control needs in Edmonton.
