There is almost no more widespread and common fear among people than the fear of spiders.

Arachnophobia is one of the most common phobias in the world, with most studies finding more than 5% of all people suffering from it. And while many spiders are not harmful, several species of spiders can be very dangerous, meaning you want to do everything you can to keep the creepy crawlies out of your house.

In homes, spiders tend to build webs in basements, garages, and corners of rooms, gaining entry through cracks in the building. Unlike many other pests, they do not go after your food, but rather build webs in sheltered areas to collect flies and other insects.

The most common times spiders enter your home is in the late summer or early autumn to search for mates. Any areas that are not commonly cleaned can act as a refuge for spiders, meaning hard to reach corners and dusty areas of your home are usually their favourite hiding spots.

While the average spider tends to avoid humans, spider bites still can occur and can cause serious harm. Bites typically result from the victim putting on a shoe or piece of clothing with a spider trapped inside. The widow spider is the only spider found in Canada that can be dangerous to humans. Symptoms depend on the bite area, victim sensitivity, and amount of venom injected. A house spider’s poison will not harm people because it is quite weak.

However, if left untreated, the bite can carry infectious diseases such as Lyme disease.

If large numbers of spiders continue to appear in your home, extermination can become much more difficult. Professional spider and pest control services have the wide range capabilities to cover and treat all ends of your home. Pest control is the best exterminator for spiders and should be consulted if your spider population grows to infestation levels.
