Spiders that are commonly found in Canadian homes include house spiders, wolf spiders, cellar spiders, fishing spiders and, much more infrequently, black widow spiders. These spiders are usually found in corners of rooms, closets, boxes, dark crevices, basements, garages, and gardens. There are only a few species in Canada are that considered to be health threats.
While spiders may creep some people out, they are actually beneficial to have around when it comes to controlling other insects and pests in garden and homes since they will feed on other insects and spiders.
One of the most common misconceptions about spiders is that they are classified as insects. This is not true—they are arachnids and are closely related to mites, ticks and scorpions.
Spiders have 2 body parts—the cephalothorax and the abdomen—8 legs and generally 6-8 eyes. The average life span of a spider is usually between 1-2 years however, some can live up to 5 years and in extreme cases up to 20 years.
Life Cycles and Habits
Spiders lay eggs in a silken egg sac that is often ball-shaped and is either hidden in a web, carried by the female or affixed to a surface. Each egg sac can house up to several hundred eggs (aka. Several hundred baby spiders). Spiders will shed their skin (aka molt) usually between 4 – 12 times before they reach maturity as they are growing.
All spiders produce silk, which is secreted as a liquid through the spinneret e and hardens with air contact. This silk is used for a variety of purposes such as making the egg sacs, capturing and holding prey, making shelters or retreats and for transferring sperm during mating.
Spiders are predators when it comes to insects and other spiders. They will typically feed on live prey by producing a venom that is poisonous to the prey. This venom is injected into the prey through their hollow fangs to immobilize the prey so they can begin the digestion process.
Because spiders can only ingest liquid, they will either inject or regurgitate digestive fluids into their prey and then they will suck in the digested liquid food.
Spiders also have a number of tactics for capturing their prey. Some species will use webbing to catch their prey, while active hunters will hunt down their prey.
How to Get Rid of Spiders (or at least evict them from your home)
So, you want to get rid of your spiders? Well the simplest method to controlling the population of spiders inside your home is to reduce the population of insects within your home, so the spiders will seek out a more dependable food source outside. Control of spiders is best achieved by following an integrated pest management (IPM) approach that involves multiple tactics, such as preventive measures, exclusion, sanitation, and chemicals applied to targeted sites.
Cottage Country Pest Control can help with this. We can come in and use a pyrethrum-based spray to eliminate the spiders from your home (both inside and outside) and also on docks, boats, garages, sheds, etc to help the outside of your home or cottage look cleaner. We also have the option available to use other environmentally conscious methods as well if that is your preference. We recommend that you book your spider spray as soon as you start seeing an excessive amount of spiders in your home, but the best time is around May since that is usually when they start showing up more (it really depends on the conditions). We also recommend booking a spider spray for early spring so that spiders don’t have the chance to make their webs in the first place.
