These reclusive visitors tend to seek out secluded, undisturbed areas to build their webs. In Alberta, spiders like humid and moist locations and can be found in basements, crawl spaces and other damp parts of buildings.
Spiders in Alberta
Spiders provide natural pest control by catching insects in their webs, but that does not necessarily mean that you want them inside your home or business. They can cause contamination of food and may pose health risks and trigger allergies. With over 580 species of spiders found in this province alone, it’s not uncommon for Albertan basements and attics to harbour spider infestations.
The following video includes some interesting information about spiders in Alberta.
Spiders are air breathing arthropods that have eight legs and chelicerae with fangs that inject venom. They differ from other arthropods in that the usual body segments are fused into 2 tagmata. The cephalothorax and abdomen are joined by a small cylindrical pedicel. Unlike insects, spiders do not have antennae.
Unlike most arthropods, spiders have no extensor muscles in their limbs and instead extend them by hydraulic pressure. Their abdomens bear appendages that have been modified into spinnerets that extrude silk from up to six types of glands. Spider webs vary widely in size, shape and the amount of sticky thread used.
Most known species are predators preying on insects and other spiders, although a few large species also take birds, lizards and fish. They use a wide range of strategies to capture prey; trapping it in sticky webs, lassoing it with sticky bolas, mimicking the prey to avoid detection, or running it down. Spiders’ guts are too narrow to take solids, so they liquefy their food by flooding it with digestive enzymes and grind it with the bases of their pedipalps, as they do not have true jaws.
How Do Spiders Get in Your Home?
Some spiders are dormant during the winter months, waking in the spring hungry and looking for prey. They get into your home via open, poorly screened windows and doors and will find the smallest cracks and gaps around door and window frames. They can also enter your home or business unintentionally when you bring in boxes or outdoor items.
