Spiders have an ominous, but often undeserved reputation. Though most spiders are venomous and considered predators, of the thousands of species found in Canada, few are actually considered a health threat.

The Spider

In fact, spiders are actually helpful in controlling other pests in the home or garden since they feed on other insects. Spiders, however, rarely bite humans. Although spiders are often unpopular, the venom of most species is not very toxic to humans, usually resulting in no more than slight swelling, inflammation, or itching sensation. Most spiders’ fangs are too small or weak to puncture human skin. The average life span of a spider is usually one to two years, but some species can live five years or even up to 20 years.

Spider Prevention Tips


Trim back shrubs and bushes. Spiders often climb from nearby branches onto home walls or rooftops. They may also make their way into overgrowth around homes in order to hide and build webs. 


Clear away clutter outside and inside your home. Spiders thrive in cluttered, messy environments. They like the cover, hiding places, and web-building environments it provides. They build their webs around various clutter to catch other pests making their way from cover to cover.


Seal any cracks or crevices found near windows and doors. They provide an easy way for spiders to make their way inside your home.


Prevent any other pests you find around your home. Eliminating their food source is an effective way to get rid of them from your home.


Remove any visible spider webs. Building webs is hard work, so spiders like them to last as long as they can. If you can keep removing webs as soon as spiders make them, they’ll probably get the message.


Replace your white porch lights with yellow LED’s. White incandescent bulbs attract all kinds of insects. Moths, flies, beetles, and more all fly toward and around lights.
